Control of screw-cutting lathe DIP-300 (1d63a)
Gearbox
Depending on the working position, starting, stopping and changing the direction of rotation of the spindle is done by handle 11 at the headstock or handle 17 at the apron. These handles control the two-way slip plate clutch and brake located inside the gearbox. The brake operates automatically in the middle disengaged position of the clutch, ensuring a quick stop of the gearbox mechanism and spindle. When moving the indicated handles to one of the extreme positions, you need to slowly move them to the middle position, and then vigorously move them to the desired extreme position.
To change the spindle rotation speed, handles 1, 2 and 5 need to be moved only at low speed or when the machine is stopped.
Gearbox
Feeds and threads are set with handles 6(A), 7(B), 9(C) and the Norton cone switch 8 according to the table located on the cover of the box. The lead screw or lead roller is turned on using handle 10(D). To directly transfer rotation from the guitar to the lead screw, the feed box is turned off with handle 6(A), and handle 7(B) is placed in the middle position. This may be necessary when cutting high-precision threads or with a special pitch using a special set of replacement gears on the guitar. It is possible to rearrange the feed box handles only at low speed.
Apron and caliper
The caliper feed mechanisms are turned on and off by the handle 14 of the falling worm located inside the apron. Manual feed of the caliper is carried out using handles 18 and 20.
Technical characteristics and operating principle
Lathe Features:
- normal accuracy of turning parts;
- the presence of additional supports allows you to sharpen long parts;
- the largest size of the workpiece is 100 cm, above the support – 60 cm;
- maximum workpiece weight – 5000 kg;
- the equipment operates using 4 electric motors of different power;
- cooling and lubrication are carried out using two pumps;
- the caliper can move both along and across in accelerated mode;
- Changing gears allows you to precisely adjust the size of thread pitches.
The main working moment is cutting the part while it is rotating in the chuck or centers. The cutting tool can be moved using the auxiliary feed motion.
Cross feed regulates the processing depth. The cutter configuration determines the shape of the part.

Design features of the machine
The DIP-500 machine has a conventional design for machines of its class. It is resistant to vibrations and heavy loads. The parts are made of cast iron.
Location of controls
On the front panel there are controls - five handles, above which there is a special plate describing the positions of the handles and their modes.
They control turning the engine on and off, setting the thread pitch and direction, and regulating the rotation speed.
Headstock
It is used to secure the part, give it rotation, and with its help all processing parameters are regulated. The headstock is located to the left of the turner.
Caliper
The caliper moves along the frame between the headstocks and feeds the cutter to the part, determining the speed and pitch of the thread. It can operate in two modes: manual and mechanical.
Apron
Used to move the carriage. Can work both mechanically and manually. There is another trigger mechanism on the apron, which can also turn on the machine and change the rotation of the part.
The front apron cover is removed, inside it there is an overrunning clutch.
Gearbox
The box is located on the headstock and is responsible for controlling the transmission mechanism. With its help, you can turn on the motion shafts and set thread parameters. It provides cutting of metric, inch and modular threads.
Replacement gears
The replacement gears are located in an assembly called the "guitar". They transmit rotation to the feed box.
Tailstock
Located to the right of the worker. Can be moved around the frame by rotating the handle and gearbox. Tools for carving, making holes are attached to it, and parts are precisely fixed.
History of the model
He was the first in the USSR to begin producing universal screw-cutting lathes in the thirties of the twentieth century. In its markings of machine tools, the plant had the slogan of the USSR machine tool industry - DIP. This abbreviation stands for “catch up and overtake.” Subsequently, DIP-500 began to be produced by the Ryazan Machine Tool Plant in the fifties of the twentieth century, and it received the marking 1M65.

Operating instructions, passport
For proper operation of the machine, you must follow the operating instructions.
- The machine weighs more than 10 tons; together with the workpiece, its weight can increase significantly. Therefore, it is necessary to prepare a separate foundation and a flat, stable platform.
- The device has four electric motors. For them to work, you need to correctly calculate the electrical load. The equipment operates from a three-phase 380 V network.
- During installation, it is necessary to check the reliability of all fasteners. Be sure to monitor the oil level and timely lubrication of mechanisms.
- The bed must be installed strictly horizontally both lengthwise and crosswise. Check the level.
The passport of the DIP-500 machine is similar to its new model 1M65. It can be viewed here.

Description
The DIP-500 machine is a turning equipment that is universal; it can be used in various fields of industry for turning operations for manufacturing products. With its help, it is possible to perform the above work with normal accuracy (H) and high productivity. Over the entire period of operation, the machine has proven itself to be highly reliable due to the quality of manufacture and ease of maintenance, and also did not require high attention or special conditions during operation.
The main movement, the cutting movement in this machine, is the rotation of the workpiece, which is processed in the chuck or centers. An auxiliary movement is a feed movement that moves the cutting tool.

The cutting tools for this type of equipment are turning tools of various types with plates made of hard alloys and high-speed materials, as well as drills, reamers, countersinks, countersinks and various thread-cutting tools and devices.
The passport of this machine contains practical information on technical characteristics and maintenance, thanks to which it had some advantages during operation, namely, it is possible to:
- perform cutting operations at high speeds;
- sharpen long and short cones thanks to the mechanical movement of the caliper;
- achieve a surface roughness index of Ra = 1.6;
- change the spindle shaft speed by switching the gearbox handles;
- adjust the feed amount over a wide range;
- perform cutting of standard threads;
- using handwheels you can extend the quill and move the tailstock;
- using the method of changing gears, adjust the pitch sizes of the cut threads and the movement of the caliper;
- using a separate electric motor of the caliper, move it in the transverse and longitudinal directions in accelerated mode.
Main technical characteristics
Design of DIP-500
The main structural elements of turning machines are: bed, headstock and tailstock.
Like all lathes of the turning group, the main structural element of the DIP-500 is the bed; it is joined by the headstock, tailstock, support, and then all other structural elements.
The bed is made of solid cast iron, at the top there are slides for longitudinal movement of the caliper, and in the middle there are hatches for cleaning chips and lubricating coolant located at an angle from the workplace.
The headstock is located on the left, it is installed using pins and secured with bolts. It contains: a spindle shaft, a gearbox, a feed switchbox, a lubrication system with an oil pump and an electrical control panel. At the bottom there are: an electric circulation pump with a container for lubricating coolant and a main drive mechanism with an electric motor.
The tailstock is located on the right; it moves along guides on the frame using a gearbox, which is driven by the rotation of its handwheel. A rotating shaft is built into the quill, which is also moved by rotating the handwheel.
