The alphanumeric index of the 1M65 screw-cutting lathe means the following: number 1 is a lathe; the letter M is the generation of the machine, the number 6 means a screw-cutting lathe, the number 5 is the maximum radius of processing the workpiece (500 mm).
Screw-cutting lathe 1M65 today
The screw-cutting lathe model 1M65 was produced at the Ryazan Machine Tool Plant, but today the production of these machines has been suspended. At the same time, leading machine tool factories switched to the production of machines of a more modern design, focused on modern tools and high cutting speeds. Such machines are equipped with modern high-quality components and reliable electrical equipment. Thanks to the use of computer-aided design of beds, an increased accuracy class for a lathe produced at a modern machine tool plant is rather the rule today. At the same time, prices for modern machines are quite comparable with prices for machines of outdated design.

Price of screw-cutting lathe 1M65
Due to the discontinuation of production of the 1M65 screw-cutting lathe, it is impossible to purchase a new machine with exactly this designation. Today on the market you can find a used screw-cutting lathe 1M65, the condition and price of which will depend on the intensity of its use. Quite often you can find machines in good condition at a reasonable price. There are offers for 1M65 machines after a major overhaul - here the price depends both on the initial condition of the machine and on the amount of work performed: there are both simply repainted “refreshed” copies, and those with a re-polished bed, new components and electrics. The latest screw-cutting lathes are often provided with a warranty, but their cost is close to 2/3 of the price of a new screw-cutting lathe with similar characteristics (this is about 5 million rubles). At the same time, there are no new analogues of the 1M65 screw-cutting lathe of domestic production. We strongly recommend that you turn your attention to significantly more modern European-made machines, which, although more expensive, are significantly higher than the level of 1M65 screw-cutting lathes of an outdated design.

Description
A heavy screw-cutting lathe 1M65 (analogous to RZTS 1R65) can be bought in Moscow to solve the problem of turning spare parts and threading parts.
An important factor is the presence of a vibration-resistant body of increased rigidity and strength. Its operation in one temperature mode allows you to create workpieces from ferrous and non-ferrous metals at normal temperatures. Increased accuracy is achieved by installing a digital remote control system. Thread cutting is carried out in modular, metric, inch and pitch formats. Turning is carried out on cylindrical, round, conical, rotating surfaces. The fast operation of the spindle with a frequency of 1250 rpm makes it possible to process the part in a timely manner. The Ryazan Lathe Plant produces an analogue of this machine 1Р65Н. For ordering, consultation, or repair of machine equipment, please contact our specialists.

Main components and principle of operation
bed , being the base of the machine, houses all the mechanisms and assemblies. On its surface there are prismatic guides for basing and moving the caliper and tailstock.
When the machine is designed with an interaxial distance of 5000 mm or more, supporting brackets are located on the frame to prevent sagging of the lead screw. Open inclined windows at the bottom of the structure serve to drain emulsion and metal shavings.
Some models have a recess in the frame; the letter “G” is indicated in the marking to indicate it.
The headstock is attached to the frame on the left side with clamping bolts and fixing pins. The closed housing contains a spindle assembly, a brake clutch, a gearbox, shift forks, and a unit for changing the size of the thread being cut. The spindle is mounted on precision rolling bearings, which are lubricated and adjusted during assembly at the factory and do not require subsequent adjustment.
A through hole in the headstock allows processing bar workpieces with a diameter of up to 120 mm.
Steady rests are used when processing flexible shafts to eliminate axial deflection. The workpiece in this device rests on crackers and rollers. There are two types of lunettes:
Movable - moves in the longitudinal direction along with the cutting carriage and is stationary. The diameter of the installed parts is from 70 mm to 250 mm.
Fixed - fixed in any position on the surface of the guides with clamping bolts. Workpiece range 70…380 mm.
The tailstock is attached to the right side of the frame in a rigid position with strips and bolts. In addition, it can be moved along the guides and fixed in any place for subsequent work. The unit body houses a movable quill, which has an accelerated movement during idle and a working movement during processing. An axial tool is installed into the conical hole of the quill to process the workpiece from the end.
The support is used to place the working tool and transmit movement to it in the longitudinal and transverse directions. A four-position tool holder with mechanical or manual movement, capable of rotating at any angle around its own axis, is installed on the top. The accelerated movement of the caliper is carried out by a separate electric motor.
The standard lathe chuck The workpiece is clamped manually using a specialized key. If necessary, use cartridges of other sizes, as well as various faceplates.
To fix the workpiece, cams are used; straight cams are clamped by the outer surface, and reverse cams are clamped by the inner diameter.
A protective casing installed in the processing area prevents chips and coolant from flying out.
Electrical equipment of the machine
All production processes of turning on, turning off and monitoring the operation of the machine are carried out by electrical equipment. It consists of motors, wiring, a push-button panel, and control equipment. The electrical cabinet is located in the rear niche of the spindle head, and the control panel is in the front part. For trouble-free operation and the elimination of short circuits, the circuit includes thermal relays with automatic switch-offs.
Main motor 22 kW, electric motor for fast feeds of the caliper 1.5 kW, mains voltage 380 V, current frequency 50 Hz.
