Design features

	The cast bed made of high-strength cast iron provides exclusive rigidity and reliability of the machine, reduces vibrations to a minimum.
	The long front infeed table improves the quality and precision of the workpieces being machined.
	The electrical cabinet and control panel are equipped with modern equipment.
	The front clamps (sectional type) and the rear clamps are adjustable for the size of the processing, completely eliminate the "tear-outs" at the entry and exit of the workpiece.
	For processing workpieces with high humidity, the upper feed rollers are made with "wolf tooth" corrugation
	The task of facilitating the passage of the workpiece through the cutting zone and the removal of resin and dust from the surface of the tables is solved by the lubrication system.
	The spindle positioning system is mounted on the front panel of the machine. For ease of operation, the mechanisms are equipped with digital indicators with an accuracy of 0.1 mm, which facilitates adjustment and control.
	The feed rate change is stepless, provided by a variator. This guarantees a smooth and constant feed of workpieces during processing. Torque is transmitted to the lower feed rollers using cardan shafts.

C-25 desktop drilling machine. Purpose and scope

Table drilling machine "C-25" is a precision machine designed for drilling precise holes in small parts, parts made of cast iron, steel, non-ferrous alloys and non-metallic materials in conditions industrial enterprises, repair shops and household workshops.

S-25 machines allow you to perform the following operations:

drilling
countersinking
deployment
reaming

The main technical characteristics of the S-25 desktop drilling machine (Kalyazinsky Machine-Building College)

Start of mass production - 1953.

Maximum drilling diameter - Ø 5 mm
Maximum drilling depth (spindle stroke) - 75 mm
Distance from the spindle axis to the bed (outreach) - 185 mm
Spindle RPM Limits - (6 steps) 1600..8000 rpm
Spindle end - AT 10 O'CLOCK
Motor power: 400 Tue
Machine weight: 128 kg

Spindle C-25 machine receives three rotation speeds from three-stage drive pulleys, which provides a choice of 3 cutting speeds - 1600, 2500, 4000 rpm at engine speed 1400 rpm. At engine speed 2800 rpm spindle speed is - 3200, 5000, 8000 rpm.

The end of the spindle machine S-25- external shortened cone B10 (Morse taper KM1) according to GOST 9953 (Shortened tool cones) - shortened cone: D = 10.094 mm.

A shortened cone B10 corresponds to a three-jaw drilling chuck of the 4th standard size according to GOST 8522 (Three-jaw drilling chucks) with a clamping range of 0.5÷4 mm.

Example symbol drilling 3-jaw chuck size 4:

Cartridge 4-B10 GOST 8522-79

Morse taper tool shortened

Tool cone - Morse cone - one of the most widely used tool mounts. Introduced by Stephen A. Morse around 1864.

Morse taper is divided into eight sizes- KM0 to KM7 (English: MT0-MT7, German: MK0-MK7).

Standards for Morse taper: GOST 25557 (Tool cones. Main dimensions), ISO 296, DIN 228. Cones made according to inch and metric standards are interchangeable in everything except the shank thread.

For many applications, the length of the Morse taper has proven to be excessive. Therefore, a standard was introduced for nine standard sizes of short Morse tapers (B7, B10, B12, B16, B18, B22, B24, B32, B45), these dimensions are obtained by removing the thicker part of the cone. The number in the designation of the short cone is the diameter of the thick part of the cone in mm.

Russian standard for shortened cones GOST 9953 Tool cones are shortened.

Russian standard for drill chucks GOST 8522 Three-jaw drill chucks.

The C-25 benchtop drilling machine is a precision machine designed for drilling precise holes from 0.5mm to 4mm.

Spindle rotation, assembled on ball bearings, is made from an individual squirrel-cage type electric motor with a 3-stage pulley, so that the spindle can rotate at six different speeds ranging from 1600 to 8000 rpm with a two-speed electric motor 1400, 2800 rpm.

Motor start done with a package switch.

Spindle smooth operation thanks to lightweight, well-balanced aluminum pulleys, an endless flat belt protected by a molded casing with an easy-to-remove cover.

Belt tension carried out by moving the motor together with the bracket.

Upper end of the spindle unloaded from a pulley rotating on individual ball bearings mounted in the machine bed bushing. The bottom end is provided taper hole for inserting the collet and thread for the clamping nut.

Drill head includes the entire drive with drilling spindle and feed mechanism. It is set to a height corresponding to the size of the product by means of a screw and nut, and is clamped on the column with a handle.

The limb ring is installed in such a way that when the desired depth is reached, the ring receives a stop and stops the rotation of the roller with the gear.

Spindle feed- manual, produced by means of a sensitive lever, gear and spindle cup.

The drilling spindle, together with the sleeve, is balanced, located in the flange, by an adjustable flat spring, which is in connection with the gear and the lever. To set the spindle to a certain drilling depth, a special collar is used, which is located on the gear shaft, and a stop screw on the bed serves as a limiter.

drilling table It is a rectangular plate with stiffeners and at the same time is the base of the column. The table is equipped with a wide groove for draining coolant and two T-slots for attaching fixtures.

Machine column can be moved along the T-slot, leaving a large support surface for drilling large workpieces with holes lying on the side.

Replacing a normal table with a large one makes it possible to install several columns side by side, and the distance between individual columns can be adjusted as you like.

Installation of the drilling machine S-25

The machine is installed on a table. Before tightening the bolts, the machine must be precisely aligned, for which a level is placed on the table along and across. After reconciliation, the bolts must be tightened tightly, observing the level.

Machine start

Before start-up, the machine must be thoroughly cleaned, washed with kerosene, wiped and lubricated, paying special attention to friction surfaces and lubrication holes. After making sure of the correct installation and assembly of the machine, having checked the rotation and movement of units and mechanisms in any direction, the machine starts for a while, to idle, during which the operation of individual mechanisms is checked.

After carrying out the above operations, if nothing is in doubt, the machine is given a load.

Machine adjustment

The clamping of the spindle cup in the bed, the movement of the motor to tension the belt, the installation of the drilling head according to the height of the workpiece and at a given drilling depth are subjected to adjustment.

Control

Turning the machine on and off is done by starting and stopping the motor, using a batch switch.

The change in speed is made by transferring the belt from one step of the pulleys to another with the motor turned off and the cover of the casing removed, guided by the speed table placed on the casing of the machine.

Machine lubrication

The most important parts to be lubricated are the spindle and the spindle cup, which during the operation of the machine are lubricated once a decade by pouring spindle oil No. 2 into the oilers.

The technical vaseline in the ball bearings of the spindle and the spindle pulley is changed once every 3 months.
