The processed lumber meets the parameters below

straightness of the base side of the processed workpiece is no more than 0.3 mm over a length of 1000 mm;
the perpendicularity of the sides of the base face of the processed workpiece is no more than 0.25 mm over a length of 100 mm;

Design features

	The cast bed, made of high-strength cast iron, provides exceptional rigidity and reliability of the machine, and reduces vibration to a minimum.
	The long front feed table improves the quality and accuracy of processed workpieces.
	The electrical cabinet and control panel are equipped with modern equipment.
	The front clamps (sectional type) and the rear ones are adjustable for the processing size, completely eliminating “breakouts” 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 zones and removing 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 change in feed speed is stepless and is 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.

Feed drive

The workpiece feeding mechanism is driven by an electric motor (1).

The feed drive from the electric motor to the module shaft is organized by a pulley (2) on the electric motor shaft and a pulley (3) on the splined shaft (4) of the modules (5). Pulleys are 2-stage, 3-groove using common V-belts A-1000 III GOST 1284.1-88 (6).

The pulley on the splined shaft of the modules moves freely, which allows you to get 4 constant gears. In combination with a frequency converter installed in the electrical cabinet of the machine and changing the rotation speed of the electric motor, the resulting overall speed range is from 2 to 40 m/min. Tensioning, loosening or rearranging the belts is done by removing the guard (7) and rotating the threaded screw (8).

S-25 tabletop drilling machine. Purpose and scope

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

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

drilling
countersinking
deployment
reaming

Main technical characteristics of the tabletop drilling machine S-25 (Kalyazin Mechanical Engineering College)

Start serial production- 1953.

Maximum drilling diameter - Ø 5 mm
Maximum drilling depth (spindle stroke) - 75 mm
Distance from the spindle axis to the bed (overhang) - 185 mm
Limits of spindle revolutions per minute - (6 steps) 1600..8000 rpm
Spindle end - B10
Motor power: 400 W
Machine weight: 128 kg

Spindle The S-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 rotation speed is 3200, 5000, 8000 rpm.

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

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

An example of a symbol for a 3-jaw drill chuck of the 4th standard size:

Cartridge 4-B10 GOST 8522-79

Morse cone instrumental shortened

Tool taper - Morse taper is one of the most widely used tool mounts. It was proposed by Stephen A. Morse around 1864.

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

Morse taper standards: 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 cone turned out to be excessive. Therefore, a standard was introduced for nine standard sizes of shortened Morse cones (B7, B10, B12, B16, B18, B22, B24, B32, B45), these dimensions were obtained by removing the thicker part of the cone. The number in the designation of a 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 0.5 mm to 4 mm.

Spindle rotation, assembled on ball bearings, is produced from an individual squirrel-cage electric motor with a 3-speed pulley, thanks to which the spindle can rotate at six different speeds ranging from 1600 to 8,000 rpm with a two-speed electric motor of 1400, 2800 rpm.

Starting the engine performed via a packet switch.

Spindle Smooth operation is ensured by lightweight, well-balanced aluminum pulleys, an endless flat belt, protected by a die-cast housing with an easy-to-remove cover.

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

Spindle top end unloaded from a pulley rotating on individual ball bearings mounted in the machine bed bushing. The lower end is equipped with a tapered hole for inserting a collet and a thread for a clamping nut.

Drill head includes the entire drive with drill spindle and feed mechanism. It is set to a height corresponding to the size of the product using a screw and nut and clamped onto the column using a handle.

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

Drilling table It is a rectangular slab with stiffeners and at the same time serves as the base of the column. The table is equipped with a wide groove for draining coolant and two T-shaped slots for attaching accessories.

Machine column can be moved along the T-slot, resulting in 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 the individual columns can be adjusted as desired.

Installation of drilling machine S-25

The machine is installed on the table. Before tightening the bolts, the machine must be accurately aligned, for which a level is placed on the table lengthwise and crosswise. After alignment, the bolts must be tightened tightly, observing the level.

Starting the machine

Before starting up, the machine must be thoroughly cleaned, rinsed with kerosene, wiped and lubricated, paying special attention to rubbing surfaces and lubrication holes. After making sure that the machine is installed and assembled correctly, and having checked the rotation and movement of components and mechanisms in any direction, the machine is started for a while, idling, during which the operation of individual mechanisms is checked.

After carrying out the above operations, if nothing raises doubts, the machine is given a load.

Machine adjustment

Adjustments are made to the clamping of the spindle cup in the frame, the movement of the motor to tension the belt, and the installation of the drilling head according to the height of the workpiece and at a given drilling depth.

Control

The machine is turned on and off by starting and stopping the motor using a packet switch.

The speed is changed by moving the belt from one pulley stage to another with the motor turned off and the casing cover removed, guided by the speed table placed on the machine casing.

Machine lubrication

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

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