Screw-cutting lathe 1M63N (3000) is metalworking equipment for industrial use, which is used to perform wide-profile turning operations (including turning conical workpieces and cutting all types of threads).

Design features

The design and technical performance of the screw-cutting lathe 1M63N (3000) are characterized by the following features:

• rigid frame with increased vibration resistance and protection from temperature fluctuations;
• controlled spindle head rotation speed and feed speed adjustable over a wide range;
• double-prism bed guides, ensuring long-term operation of the screw-cutting lathe 1M63N (3000) without loss of accuracy;
• the possibility of reverse rotation of the spindle for thread cutting (speed is 30% higher than with direct rotation);
• turning of long-length conical workpieces is carried out with simultaneous longitudinal movement of the support and rotary feed of the cutting slide;
• feed box with a rigid kinematic chain and two electromagnetic clutches for switching feeds without stopping work;
• all critical gears of the kinematic chain of the screw-cutting lathe 1M63N (3000) are made of ground and hardened alloy steel;
• the working area has protective fences, and the safety of the main technological processes is ensured by blockers.

Equipment

The basic equipment of the screw-cutting lathe 1M63N (3000) includes:

• three-jaw chuck;
• movable steady rest (20-150 mm);
• fixed steady rest (20-350 mm).

When purchasing a screw-cutting lathe 1M63N (3000), you can additionally order:

• four-jaw chuck with a diameter of 500 mm;
• fixed rests of various sizes (200-410 mm, 40-215 mm, 20-160 mm);
• cone ruler;
• thread indicator;
• quick release tool holder.

The spindle of the 1m63 machine is mounted on two bearings:

1. The front spindle bearing is a special 2-row radial bearing with short cylindrical rollers and a tapered inner ring, with adjustable radial clearance.
2. The rear spindle bearing is an angular contact ball, working in tandem with a thrust ball bearing that absorbs axial feed forces during straight turning.

A rod with a diameter of up to 65 mm passes through the 70 mm spindle hole.

The spindle receives from the gearbox 22 stages (actually 24 stages, 2 of which overlap) of rotation in the range from 10 to 1250 rpm (progression denominator 1.26) and 11 reverse rotation speeds in the range from 18 to 1800 rpm.

The spindle speed is changed by moving the gear blocks along the splined shafts using two handles located on the front wall of the headstock. The spindle is reversed by a friction clutch. Braking - electromagnetic clutch.

The front end of the spindle is made according to GOST 12593 (DIN 55027, ISO 702-3-75) for a rotary washer, with a centering short cone 1:4 (7°7′30″). The nominal diameter of the cone is D = 139.719 mm, the nominal size of the spindle end is 8. The internal (tool) cone of the spindle is Morse 6. The standard diameter of the lathe chuck is 250, 315, 400, 500 mm, version - type 2 (see article Lathe chucks)..

The support of the 1m63 machine of a cross design has a mechanical movement of the upper part, which allows turning long cones. Turning of short tapers is also carried out by moving the upper part of the support.

The caliper carriage moves along the frame guides (longitudinal movement), and the transverse caliper slide moves along the carriage guides (transverse movement); both can be manual, mechanical, working and accelerated. The rotating part of the caliper, located on the transverse slide, has guides for moving the upper part of the caliper (cutting slide) with the cutting head. The lower part of the support (cutting slide) can also be moved manually and mechanically. The cross screw nut has a slot for adjustment to eliminate backlash. The axial forces of the transverse screw and the screw of the upper slide are absorbed by thrust ball bearings. The guides for the longitudinal movement of the caliper have textolite linings.

All basic operations are mechanized in the machine:

• longitudinal mechanical movement of the caliper (longitudinal working feeds)
• transverse mechanical movement of the caliper (transverse working feeds)
• mechanical movement of the cutting slide (working feed of the cutting slide)
• accelerated movements of the caliper in the longitudinal direction from an individual electric motor
• accelerated movements of the caliper in the transverse direction
• accelerated movements of the cutting slide
• The spindle is also braked automatically when the friction clutch is turned off.

Changing the feed rates and adjusting the pitch of the thread being cut is carried out by switching the gears of the feed box and adjusting the set of interchangeable gears.

Mechanical movement of the upper part of the support allows turning of long cones. Turning of short tapers is also carried out by moving the upper part of the support.

Changing the feed rates and adjusting the pitch of the thread being cut is carried out by switching the gears of the feed box and adjusting the set of interchangeable gears.

The support has rapid movement in the longitudinal and transverse directions, which is carried out by an individual electric motor.

Closed apron with removable front wall (lid). The movement of the caliper group is transmitted by an apron from the lead screw or lead shaft. Due to the presence of 4 electromagnetic couplings in the apron, control of the apron is concentrated in one handle, and the directions of turning the handle on coincide with the direction of feed movement. An additional press of the button built into the same handle activates the accelerated movement of the caliper. Thanks to: the presence of an overrunning clutch in the apron, the inclusion of rapid speed is possible when the feed is on. To avoid simultaneous activation of the motherboard, the nuts and the feed of the activation handle are interlocked.

Closed feed box. Corrected gears installed in the feed box make it possible to cut two types of threads, metric and inch, without rearranging replaceable gears. When rearranging replaceable gears, it is possible to cut two more types: modular and pitch threads. Direct connection to the screw is also provided (bypassing the feedbox mechanisms) for cutting precise and special threads. To obtain increased feed or right-hand threads, a gear block located in the gearbox is provided. The feed box housing has 2 longitudinal bores in which shafts are mounted on rolling bearings. Gears are made of chrome steel and hardened. The selection of feed rates is carried out using two handles by moving the gear blocks. Selecting the type of thread or switching on the feed is also done using handles. To turn on the screw directly, handle 5 must be placed in the “metric thread” position, handle 1 in the “screw directly” position, handle 8 in the “lead screw” position (see control diagram Fig. 6; 7).

The 1M63N machine is time-tested.

This screw-cutting lathe of normal accuracy 1m63N is designed to perform various turning operations, such as turning cylindrical surfaces, trimming ends, turning grooves, cutting off a machined part, boring internal cylindrical surfaces, drilling, countersinking, reaming, processing conical surfaces, as well as for cutting metric, inch and pitch threads. High drive power and rigidity of the machine, a wide range of spindle speeds and feeds allow full use of the capabilities of progressive tools when processing various materials.

Design and operation of the main components of the machine

The machine consists of the following main components: Bed 1, feed box 2, replacement wheels 3, headstock 4 with spindle 6, electrical cabinet 5, apron 7 and support 9, movable 8 and fixed 10 rests, tailstock 11, electric motor for rapid movement support 13, support mechanism for the lead screw and shaft 14. Bed.
The bed is the basic assembly unit on which other assembly units are mounted. The bed is solid cast with stands, has two prismatic guides for the carriage and two for the tailstock, one of which is flat. Inside the frame there are inclined hatches (windows) for removing chips and coolant. The right cabinet contains a tank with emulsion and an electric pump. The main drive electric motor is mounted on the left pedestal at the back. Headstock. The headstock is installed on the left head part of the bed. All gears of the kinematic chain are mounted on shafts and spindles, made of chromium steel, hardened and ground. The shafts are mounted on rolling bearings. The spindle with a through hole and internal cones has two supports. The front support is a double-row bearing with short cylindrical rollers. The rear support is an angular contact bearing paired with a thrust ball bearing. Changing the spindle rotation speed is achieved by moving gear blocks along splined shafts using two handles located on the front wall. Direct and reverse rotation of the spindle is carried out by a friction mechanical clutch, and braking is carried out by an electromagnetic clutch. Tailstock. The tailstock moves along the bed guides on four radial ball bearings installed in the bridge. The headstock is secured to the frame guides using two strips with four bolts. The transverse displacement of the headstock body relative to the bridge is carried out using two screws and a nut installed in the bridge. The quill is moved by a handwheel. Caliper. The support of the cross design has longitudinal movement along the prismatic guides of the frame and transverse movement along the carriage guides. Movement can be carried out manually or mechanically. There is a mechanism for quickly moving the caliper. The rotating part of the caliper has guides for moving the upper part of the caliper with the cutting head. Apron. Closed apron with a removable front wall (lid). The movement of the caliper is transmitted through the apron from the lead screw or lead shaft. The apron mechanism is equipped with four electromagnetic clutches, which made it possible to concentrate control on one handle, and the directions of activation of the handle coincide with the direction of feed movement. The same handle has a built-in caliper fast travel button. Thanks to the presence of an overrunning clutch in the apron, high speed can be activated when the feed is on. Feed box . The feed box has two longitudinal bores in which shafts are mounted on rolling bearings. The gears are made of chrome steel and hardened. Adjustable gears make it possible to cut two types of threads, metric and inch, without rearranging replacement gears. When rearranging replaceable gears, it is possible to cut two more types of threads - modular and pitch. Replaceable gears . Replaceable gears located on the wall of the headstock housing allow for feeding and cutting metric, inch, modular and pitch threads in accordance with the passport data. Lunettes . For processing non-rigid parts with a diameter of 20 to 150 mm, the machine is equipped with movable and fixed rests. The steady rests are equipped with replaceable rollers and crackers, installed depending on the operating conditions. Cooling. From the electric pump installed in the right cabinet of the frame, the coolant is supplied to the tool through a pipeline and hose, and then flows into two troughs installed in front and behind the machine, from where it returns to the electric pump tank.
The troughs and tank must be cleaned at least once a month. You can get more detailed information here https://www.td-osz.ru/ beconected.com

Controls

Most of the controls of the 1M63N screw-cutting lathe are concentrated on the headstock, carriage and caliper apron. The movement of the caliper in working directions can be carried out either mechanically or manually. Installed overrunning clutches allow you to enable fast feed of the caliper without stopping the machine. There is an electrical lock to prevent rapid feed when the lead screw nut is engaged.

Inside the frame body, under the working area, there are hatches for removing chips and draining coolant. The coolant and lubricant is reused many times, thanks to its return to the container through a filter system.

The outer (front and rear) cabinets of the frame are hollow. The main drive motor is located in the front (left), and the pump electric motor and a tank with cooling emulsion are located in the rear (right).

On the rear wall of the headstock there is a block of replaceable gears (guitar) for transmitting and adjusting rotation from the headstock to the feed shaft. Sets of replaceable gears allow you to rebuild the machine to cut threads of acceptable types.

Modifications

Time and growing needs bring with it the need to make improvements. Our unit could not do without them. Its main modifications include the following models:

• 1M63F306, produced since 1973, was distinguished by the presence of CNC (this difference is also present in 1M63FZ and 1M63RFZ);
• 1M63F101, released in 1976, had a digital display device (DDU), which counted the lateral movement of the caliper;
• 1M63B, distinguished by its speed and increased power (this also applies to modifications 1M63BG and 1M63BF101);
• 1M63M with increased power, like 1M63MF101 and 16P30;
• 1M63N, released in 1992 and completing the series, was distinguished by normal accuracy (1M63NF1 and 1M63NF101, moreover, were supplemented by a DRO system that counted movements in a 3-dimensional coordinate system);
• 1M63N-1, which had normal accuracy and a shorter frame (1M63NF10M also had a digital display);
• 1M63NG, distinguished by a notch on the frame;
• 1M63NP, the advantage of which was increased accuracy.

Some of the listed machines could use a little more attention. For example, considering one of the latest modifications (1M63N), we can highlight several design features of the model:

• the letter “N” in the name indicates normal processing accuracy, which was ensured by three factors: temperature stability, vibration resistance and structural rigidity;
• impressive service life of the turning machine, ensured by two prismatic guides located on the bed, and other highly reliable components;
• accelerated thread processing due to the fact that reverse rotation of the spindle has a 30% higher frequency than direct rotation;
• gears, which are made of alloy steel;
• increased operational safety guaranteed by machine locking systems, as well as enclosing cutting zones;
• a more powerful engine compared to the original model;
• ability to process workpieces up to 10 m long and weighing up to 3.5 tons.

The 1M63 machine we reviewed has enough features that have ensured its popularity and recognition not only at home, but also abroad. A huge number of modifications were created on its basis, adding even more advantages to this machine. Despite the fact that in the new century a huge number of modern machines have already been created, superior in many ways to the half-century-old hard worker, he and his improved models continue to be in service, processing thousands of new parts every day.
