Purpose
The GS526U screw-cutting lathe is used to remove a layer of metal from the surfaces of bodies of revolution. It is screw-cutting, which allows you to create various types of threads. The technical potential and relatively low cost of the GS526U determined the spread of this model in a wide variety of industries. Despite the fact that a screw-cutting lathe is technically inferior to modern equipment, its maintainability and affordability make it a rather attractive offer for factories in the mechanical engineering industry.
Introduction to the topic
The Belarusian development, the screw-cutting lathe GS526U, offers many possibilities. The functional purpose of the equipment includes not only turning with class P precision on cylindrical workpieces and parts of other shapes, but also cutting threads of various types. An undoubted feature that makes this family of units very popular in repair shops and tool shops of enterprises is the ability to order the desired version of the machine, as well as additional sets of tools and equipment.
Peculiarities
The GS526U machine in question has technical characteristics that allow it to be used for processing parts with accuracy class P. The manufacturing plant produces this model in various versions to order from the buyer, its purpose is turning conical and cylindrical surfaces, thread cutting. Design of a screw-cutting lathe:
- The GS526U 01 lathe has a variety of holes in the spindle. The manufacturer allows you to specify this technical parameter depending on your needs.
- Gears are made of high-strength steel, which makes it possible to significantly increase service life: the gearbox can withstand heavy loads. The screw-cutting lathe GS526U has a design that allows you to replace gears at the time of gearbox repair.
- The replacement gear guitar does not change when cutting threads 11 and 19. This characteristic significantly simplifies the tasks assigned to the master. A universal screw-cutting lathe is used to produce high-quality threads.
- The GS526U screw-cutting turning machine is equipped with an apron that has its own drive.
- The center in the tailstock quill is Morse 5, created according to established standards.
- The feed box makes it possible to adjust the supply of the cutter. The feed box is connected to the main kinematic circuit. The mechanical feeding method is also highly accurate. The transverse stroke is also mechanical.
- The spindle speed varies from 16 to 2000 rpm. The installed gearbox allows you to adjust the processing mode with the greatest precision. The lead screw is also manufactured using high strength steel. The machine motor can operate smoothly all day long thanks to an efficient cooling system.
- The weight of the equipment together with the delivery set of screw-cutting equipment is 3,500 kg. Before installation, it is worth considering this characteristic, since the base must withstand the load and absorb some of the vibration. The heavy weight complicates the process of transporting the screw-cutting lathe GS526U.
- The delivery set includes a passport, which indicates the design of the GS526U screw-cutting lathe, an electrical diagram, an instruction manual and a kinematic diagram.

GS526 – Lathes 1K62, 16K20 and modifications
In general, I visited Gomel, the GZSU plant, walked through the production, looked at the full cycle of their activities. And, yes, this is the only manufacturer of a full cycle of universal lathes. The plant employs about 600 people. Production is operating. However, the production is clear that it is not new, the main park is from Soviet times.
From the purchased ones - only cast blanks. The camps are either Gomel or Sasovo. At that moment when I was in the camp there were Sasovskys. This can be seen by the molded "SASTA" on the open end of the bed. I examined with my own eyes the manufacturing cycle of the frame - milling, grinding, high-frequency hardening, finishing grinding.
Feed boxes, aprons, headstocks are also made there from cast iron castings. Lines for milling housings, manufacturing gears, shafts, spindles. The caliper is the same.
Assembly area - mechanics assemble the machines, scrape down the surfaces for paint. However, doubts crept in here - the caliper came from the factory with fittings on the guide planes made of polymer material. It is the attachments that are scraped onto the frame. Controversial point.
Then there was a meeting with the factory designer, where I asked a question regarding the cut threads on a standard guitar set. Here I fell into a complete stupor. The designer told me that the lead screw has only a direct drive through the guitar, for each thread you need to put your own set of gears in the guitar, and thread cutting in a standard set of guitars occurs not through the screw and the mother screw, but through the caliper drive shaft. At the same time, the designer leafed through the passport for a long time trying to find something there, and eventually showed me the formula... At the same time, I talked about the standard series of metric and inch threads.
But what can I say, at least not China. And they assured me that they haven’t supplied machine components to Russia for a long time - they don’t order them, the last one to take them was Astrakhan, and even that was closed. And Gomel was essentially a branch of the Red Proletary for the production of units, after which it inherited the license for the entire machine.

Transmission
Designed for smooth transmission of kinematic force to the drive shaft of the feed box. This transmission occurs in parallel with the installation of a certain combination of replaceable gears. Such machines redistribute gears based on the configured positions of the feedbox inlet holes.
Based on the technical properties of the gearbox, it is often compared to a guitar on which gears are located to change the position of the feed. Each replacement wheel is equipped with its own splined hole; thanks to this element, bolting occurs.
