CNC vertical grinder. Calibrating and grinding machines

PURPOSE:

Jig grinding machines are designed for grinding complex shapes and holes, where the highest degrees of machining accuracy are required. According to the principle of operation, these machines are very similar to jig boring machines, but the difference is that grinding machines have a higher processing accuracy (much higher than that of a simple milling or turning machine) and the speed of the grinding spindle.

APPLICATION AREA:

Machine tools are used in tool production, the manufacture of dies, matrices, the production of complex modern mechanisms, wave gearboxes, products requiring particularly high machining accuracy, etc. These machines use linear actuators, high-speed pneumatic or electric motors and various systems cooling, both the machine itself and the workpiece.

The machine works with high frequency spindle rotation. Spindles can be changed depending on the requirements of the processing, in order to achieve an optimal result. Some of the spindles are fixed speed (60,000 rpm), others are adjustable (between 30,000 and 50,000 rpm) and still others are very high speed(150,000 rpm). The main spindle has a wide range of speeds to ensure the desired result. The machines have standard movement axes (X and Y). All axes are indexed to 0.0001 mm using an electronic flywheel. The machine is equipped with high-precision linear drives. The spindle rotates at variable speed and moves with an accuracy of 0.0001 mm for grinding high-precision holes. Only the use of such technologies will achieve the desired result with precision processing.

They produce cylindrical grinding, surface grinding, internal grinding, centerless grinding, contour grinding, CNC tool sharpening machines. Multi-purpose grinding machines have also been created that provide processing in a chuck from one setup of the external and internal surfaces of workpieces such as bodies of revolution. Such machines have several grinding spindles and automatic tool change either to replace a worn wheel or a wheel corresponding to the diametrical size of the hole being machined. Tool magazine capacity 12-18 pcs. On the basis of multi-purpose grinding machines, flexible production modules (FPM) serviced by PR were created.

CNC grinders, in terms of metal processing, perform the same types of work as a manual grinder. CNC machines use the same cutting tool, the same cutting speeds, coolant, etc. The increase in productivity and the expansion of the technological capabilities of CNC machines are not provided by the processes associated with metal removal, but only by controlling and reducing auxiliary time processing.

A feature of grinding that makes it difficult to programmatically control the process is that the wear of the grinding wheel is commensurate in magnitude with the machining allowance (in contrast to the blade tool). The amount of wheel wear is determined by the action of various factors and is 1/50 of the allowance to be removed. Therefore, CNC grinding machines are equipped with automatic wheel wear compensation mechanisms. The dressing mechanism is controlled by the CNC device. The CNC system must be closed to compensate for the elastic temperature deformations of the technological system, its geometric inaccuracies. Measuring systems of CNC machines must have a high resolution

A feature that provides small tolerances for positioning accuracy. In cylindrical grinding machines, the devices provide continuous measurement of diameters during grinding with a relative error of not more than 2 x 10 "5 mm. The control of the longitudinal movements of the table is carried out with an error of not more than 0.1 mm for cylindrical grinding and 0.02-0.03 mm for end-round grinding - wrapping machines.

Perforated tape is most often used as a program carrier. Grinding machines are usually equipped with CNC control systems that provide 3-4 coordinate control. In machines that work with several circles, it is possible to control 5-6 and even 9 coordinates. The relationship between the CNC and the operator of the CNC grinder is in most cases carried out interactively via the display.

CNC surface grinding machines, depending on the purpose, can have one, two or three programmable axes of movement: X-longitudinal feed of the table, Z-transverse feed of the table, Y-verti - 268

Kalalny giving of a grinding wheel (fig. 166, a). Additionally, it can carry out software control of the wheel speed as it wears out (to maintain a constant cutting speed), feed rate and other parameters. Processing of flat surfaces can be programmed in pendulum and creep grinding modes. With pendulum grinding (Fig. 167, a), a table with a workpiece fixed on it reciprocates relative to the grinding headstock carrying the circle. The feed along the Z-axis (transverse) can be carried out after one table move - working out one line (Fig. 167, 6) or simultaneously with the longitudinal feed along the X-axis (Fig. 167, c). In the latter case, the return stroke is usually performed without cross feed to improve
surface quality. After processing a flat surface, the wheel is fed down onto the workpiece to ensure metal removal during subsequent work strokes. With deep-feed grinding (Fig. 167, e), the allowance is removed in one working stroke at low speeds of movement of the workpiece relative to the circle. The processing of curved surfaces is carried out by moving the grinding headstock with a circle simultaneously along two coordinates (Fig. 167, e), or, as in conventional machines, by using the coordinate editing of the circle (Fig. 167, e). Editing is carried out according to the UE with a diamond pencil installed in a mechanism controlled by the CNC (Fig. 167, g). The required profile is obtained by simultaneously moving the wheel (Z-axis) and the diamond pencil (X-axis). According to UE, it is possible to set not only the trajectory of the dressing tool, but also the dressing process technology, taking into account wheel wear compensation. In most cases, editing is performed periodically (Fig. 167, h). In deep and profile grinding, when the wheel wears out, continuous dressing with compensatory displacement of the wheel is especially intensively used.

Cylindrical grinding machines with CNC have two main program-controlled movement axes (see Fig. 166, 6) Z-transverse feed of the grinding wheel, X-longitudinal feed of the workpiece. This allows you to program the processing of the necks of stepped shafts by the method of plunge (Fig. 168, a) and through grinding according to any work cycle; set the spark-out oscillation along the X axis after plunge grinding (Fig. 168, c), program the processing of the ends (Fig. 168, d), and with the X and Z axes simultaneously controlled, grind conical and more complex surfaces in a pass - 270

Schenia (Fig. 168, e). In machines, a larger number of coordinate axes can also be provided.

CNC face circular grinding machines can have up to ten controlled coordinates (see Fig. 166, c) - three main (X, Zy Q and six auxiliary positioning coordinates: B - table rotation for processing a cone, Y - axis of the active control device, Z - movement of the device for the axial orientation of the circle relative to the workpiece when processing stepped shafts, W - displacement of the tailstock when correcting the workpiece.

On machines, they program the processing of fillets with different radii (Fig. 169, a), grinding the ends (Fig. 169, b), simultaneous processing of cylindrical end surfaces (Fig. 169, c, d), plunge grinding of shaped surfaces (Fig. 169, e) and other operations. The presence on the universal CNC machine of an internal grinding head controlled from the UE allows simultaneous grinding of external and internal surfaces.

CNC internal grinding machines (see Fig. 166, d) can have one, two or more controlled coordinates. The main ones are Z-transverse feed, X-longitudinal feed. Often, for the convenience of developing a UE, the Xі coordinate is introduced, which coincides in direction with X, along which the longitudinal movement of the grinding wheel is specified. The presence of these axes allows you to program all the main grinding schemes performed on the machine: through and blind cylindrical holes (Fig. 170, a, b), inner end surface (Fig. 170, c), chamfer (Fig. 170, d), conical holes (Fig. 170, e),

The outer end surface (Fig. 170, g), etc. The machines also provide for editing the circle according to the UE.

Cylindrical grinding semiautomatic device ZM151F2 with CNC. The machine is used for grinding smooth and intermittent surfaces of stepped shafts. Are applied in the conditions of small and medium-scale production. The machine provides performance in automatic mode longitudinal, plunge and line grinding, followed by longitudinal grinding, as well as shoulder grinding. During processing, the diametrical dimensions of the shafts are actively controlled. The accuracy class of the machine is P, it ensures the accuracy of diametrical dimensions according to the 6th grade. The machine can be built into automated areas controlled from a computer.

Technical characteristics of the machine. Largest dimensions installed workpiece: diameter 200 mm, length 700 mm, diameter of the workpiece processed with active control, 0-85 mm, workpiece rotation speed 50-500 min "1 (steplessly adjustable), grinding wheel speed no more than 50 m / s, working feeds grinding headstock for pre-treatment 0.2-0.12 mm/min, final 0.1-0.6 mm/min, finishing 0.02-0.12 mm/min, fast approach speed of the grinding headstock 1700-930 mm/ min, table movement speed 0.05-5 m/min (number of steps 10), dimensions machine 4950 x x2400 x 2170 mm.

CNC - specialized for grinding machines. UE input - by means of decade switches. Dimensions in UE are set in absolute values. According to the UE, eight steps of the workpiece can be ground. The number of programmable coordinates is 2. Work is performed sequentially for each coordinate. The machine is equipped with two measuring devices and their corresponding corrective systems: to determine the deviation of the dimensions of the workpiece and circle. The wheel diametrical wear control (X coordinate) is performed and corrected indirectly when measuring the workpiece during processing with an active control device. The control of the base end of the workpiece (Z coordinate) is carried out by an axial orientation device. This control is needed to bind the workpiece to the machine coordinate system (for example, in the case of measuring the depth of end holes). The device has a probe, at the moment of contact of which the workpiece is corrected "zero" of the position sensor of the machine table. The discreteness of movement along the coordinates: X - 0.001 mm, Y - 0.01 mm. The CNC has a digital display.

Basic mechanisms and movements in the machine. The rigid frame A of the machine (Fig. 171, a) has guides along which the table G reciprocates, carrying the upper rotary table, which can be rotated at an angle. The workpiece is installed in the centers of the front B and rear E headstocks. She gets a round-robin motion. The grinding headstock D moves along the transverse guides of the bed, on the body of which the transverse feed mechanism D is mounted. The grinding spindle, in addition to rotational movement, has axial movement in automatic mode. Auxiliary movements: insertion and withdrawal of measuring instruments into the processing zone, manual movements of the table and the grinding headstock, approach-retraction of the tailstock quill, movement of the follower stop, longitudinal movement and feed to the circle of the diamond tool during dressing, which is performed by device B. The machine is equipped with a device for circle balancing.

Machine kinematics. The main movement of the spindle of the VIII grinding wheel receives from an asynchronous electric motor Ml through a V-belt transmission. The spindle is mounted on hydrostatic bearings.

The axial movement of the spindle is carried out hydraulically. Oil enters the C5 cylinder and moves the piston-rack, which turns the pinion wheel Z = 17, the shaft XIV and the cam 4. The latter moves the spindle VIII through the plunger 5 and the lever system 6. After the contact of the circle with the end face of the workpiece, the forced feed stops and the end face is grinded. Spindle returns to starting position spring.

The table is moved by a hydraulic cylinder C1 or a manual movement mechanism from the handwheel 9 through gears Z= 14/62, Z= = 12/48 and rack and pinion. When moving the table from the hydraulic drive, the manual movement mechanism is automatically turned off. Hydraulic cylinder C2 disengages the shaft-wheel Z= 14.

The rotation of the workpiece is carried out from the electric motor constantly

Go current M2 through two V-belt drives. Spindle II is stationary, the rotation of the workpiece is transmitted by the faceplate leash.

The transverse feed mechanism provides an accelerated feed, which is reduced by 2 times during the cycle, a working feed and an adjusting manual movement of the grinding headstock. The installation supply is carried out by the handwheel 8 through the conical wheels Z= 39/39, the worm pair Z= 2/20 and the rolling screw-nut pair X (p = 10 mm). The accelerated movement of the grinding headstock is carried out from a two-speed asynchronous motor M4 through a worm gear Z= 2/30 and a pair of rolling screw-nut X.

The automatic working feed of the grinding head comes from an adjustable DC motor M3 (type SL-569) through the worm pairs Z= 2/30 and Z= 2/40 with the electromagnetic clutch M on and then through the gears Z= 39-39, Z= 2 -40. The frequency of rotation of the MZ electric motor shaft is controlled by a TG tachogenerator (type CJI161, N= 0.009 kW, n = 20...4000 min1).

In plunge grinding, feed deceleration from forced to finishing is carried out by changing the speed of the electric motor, which is controlled by the control signals of the measuring devices. The value of the working cross feed Sn \u003d \u003d n (2/30) x (2/40) x (39/39) x (2/40) x 10. Periodic cross feed is possible with periodic switching on of the Mx clutch.

Rear grandma. The axial retraction of the tailstock quill is carried out hydraulically when the rack piston is moved (/i = 2 mm) and manually by turning the wheel shaft Z = 24. The workpiece is clamped in the centers by a spring. The headstock is equipped with a cone-shaped ™ output mechanism on the workpiece being processed. taper hole under the center it is bored eccentrically relative to the outer diameter of the quill (see section 3 - 3). Therefore, when the M5 motor is turned on, it is possible to feed the workpiece by turning the quill. The center of the tailstock can then move 0.05 mm. Grinding of the neck of the workpiece at the headstock occurs after the preliminary installation of the axis of the centers. When the size of this neck is obtained, the neck located at the tailstock is ground. The diametrical size of the neck is controlled by the position sensor of the grinding headstock. The latter stops at a certain moment and the feed from the taper output mechanism begins.

Editing the grinding wheel. The diamond tool installed in the quills of the dressing mechanism is fed to the grinding wheel automatically by a hydraulic system or manually by rotating the handwheel 2 located on the shaft K, through gear pairs Z= 2/72, Z= 27/7 and lead screw III. Fig. 171 not shown) turns the ratchet wheel Z= 200, mounted on the screw III, by means of the pawl. The longitudinal movement of the dressing device comes from the hydraulic cylinder of the central lock. On the carriage at an angle of 45 ° moves from the hydraulic cylinder Ts4 body, based on a probe on a straight copier 3. The copier provides editing in one or two working strokes. Fine adjustment of the position is carried out with a screw (p = 1.5 mm).

Mechanisms of water measuring clamp and axial orientation device (Fig. 171, b). Cylinder 2 is pivotally mounted in column 7 (not shown in Fig. 171, b). A measuring clamp 77 is installed on the rod 10. The rod moves along the axis of the circle and has two extreme positions. The removal of the bracket from the processing zone is carried out by supplying oil to the lower cavity of the cylinder 2. The rod 3, acting on the washer 7, through the lever 4 rotates the body 6 of the bracket on the axis 8. Thus, the bracket is removed from the measurement zone. With further movement of the rod J, the bracket and the mechanism for inserting the device of axial orientation mounted on the bracket 9 rotate around the axis 5 and move upwards. The input of the measuring clamp is carried out by moving the piston down.

The axial orientation device 16 is fixed with a terminal clamp on the bracket 75, which can rock on the shaft 14 from the piston 12 of the hydraulic cylinder 77. When the device is inserted, the oil enters the rodless cavity of the cylinder 77, and when it is output, it enters the rod cavity. In the absence of pressure in the rod cavity, spring 13 is activated. The end positions of the piston are fixed by microswitches.

Machine cycle. 1. Turn on the electric motors of the hydraulic system, lubrication pumps and machine operator, and then the grinding wheel drive. 2. The measuring clamp is raised, the tailstock quill is approached, the workpiece is clamped in the centers. 3. On the remote control panel program control press the "Automatic" button, while: a) the grinding headstock moves to the rearmost position controlled by the limit switch; b) the table occupies a position corresponding to the coordinate of the end face of the first stage being ground without taking into account the correction for centering; c) a measuring clamp and an axial orientation device are brought in, the probe of the latter rests against the workpiece, the table moves to the right until it touches the base end of the probe workpiece; d) the origin of the system is combined according to the established workpiece; e) the probe of the axial fixation device is removed. 4. The wheelhead starts moving forward at rapid feed (1700 mm/min) until the wheelhead position sensor engages the follower stop and commands it to slow down to twice the travel speed. The rotation of the workpiece and the coolant supply are turned on. 5. With further movement of the grinding headstock for 2-3 mm to a given size, the travel speed slows down to the value of the forced feed (6 mm / min). 6. The speed of movement of the grinding headstock is switched from forced to preliminary by the command of the contact relay of the circle with the workpiece, or by command from the position sensor 276 of the grinding headstock, if the machining allowance is less than 0.2 mm. 7. The speed of movement of the grinding headstock is switched from preliminary to final by command of the position sensor of the grinding headstock. When switching to the final speed, the jaws of the measuring clamp close on the workpiece and the subsequent commands to switch to finishing speed and end the work are given by the clamp. The latter cannot be used when processing intermittent surfaces. Therefore, finishing is performed by command of the wheelhead position sensor. 8. After grinding the first step, the table moves to set the next programmed step against the circle, the next step of the workpiece is ground. After finishing the processing of the last step of the workpiece, the grinding head moves to the rear end position and the measuring device is retracted.

Automatic wheel dressing is activated when grinding workpiece steps, where wheel wear compensation is provided (radial correction). Correction is carried out at the moment of processing the step, the diameter of which is controlled by a measuring clamp. Therefore, it is first necessary to grind that step of the workpiece, the control of which can be carried out with a bracket.

The hydraulic system of the machine performs: longitudinal reverse movement of the table with nine fixed speeds, longitudinal movement of the measuring bracket, opening of its jaws, approach and withdrawal of the probe of the axial orientation mechanism, input and output of measuring instruments, withdrawal of the tailstock quill, control of the grinding wheel dressing device, movement of the grinding spindle headstock, disabling the mechanism for manually moving the table, lubricating the bearings of the grinding headstock spindle and guides.
