Russian high-quality soultions in the field of metalworking from Penza region

The Srednevolgsky stankozavod (machine-tool plant) Ltd. was established in 1876. It is one of the oldest machine building enterprises, not only in Russia, but also in the world. During more than 100 years the plant has produced more than half a million of lathes. Legendary models of machines 1А616 and 16B16 are still respected by turner for its high reliability, easy operation and high processing accuracy. The plant was the first in the USSR to master the production of CNC machines.

Srednevolgsky stankozavod Ltd. has all the technological competencies for production of high precision lathes. The Machine Plant range of products includes more than 200 units of technological equipment which enables high-pre­cision machining of large pieces of casting, gear process­ing, ultra-precise finishing operations of surface grinding of spindles, shafts, gears, precision boring operations. All me­chanical components of machines, including base frame, spindle assembly, stand, tailstock are made directly at the facilities of Srednevolgsky stankozavod Ltd.

To ensure the required accuracy and its long-term opera­tion, all basic parts of machines are subjected to various stabilization of geometrical sizes (natural and artificial ag­ing), bed guides of high quality cast iron are heat treated at high frequency current installations. Critical parts of ma­chines (spindles, quill, lead screws, gears, etc., are made of alloy steels which are subjected to various heat treatment methods, including ionic and gas nitriding, nitrogen and ionic carbonization, etc.

When manufacturing critical and basic parts, the follow­ing is widely used: ultra-precise grinding, gear-grinding and thread-grinding machines and other advanced equipment. The plant metrological service using advanced inspection instruments, for example, laser interferometers, profilers, different types of microscopes, hardness measuring instru­ments, etc. contributes to stable product quality.

The basic principle during assembly and installation of the products is subassembly and bench assembly with wide running-in of assembled units. To reduce noise and vibra­tion, the main motion drive components and individual parts are dynamically balanced. Finished machines are tested for reliability, rigidity and running under power (cut- ting1).

At present, the plant is completely focused on the produc­tion of machines with precision accuracy classes А, В and П according to GOST 8-82. The plant is the only Russian manufacturer of ultraprecision lathes.
