There are over 200 units of modern high-precision equipment installed in production shops, including:
machining centres, CNC machines, flat surface and centerless grinders, assembly lines of the leading manufacturers, having the EU certificates and widely used in Europe, Asia and the USA.
The technological route at our enterprise starts with the receipt from suppliers of a machined blank with standardised allowances for its further heat-treatment, grinding and assembly operations.
Heat-treatment provides parameters of the metal structure and hardness of the blank.
In the course of grinding treatment, work surfaces are formed at starting operations (edges of internal and external rings and an external cylindrical surface of the external rings). During the subsequent operations, work surfaces are formed that pass grinding and superfinishing treatment (bearing races, borders and fitment bores).
Precision of the equipment at all technological stages allows manufacturing rings to assemble bearings of the accuracy grade 6 and above.Methods of statistical regulation of technological processes are introduced at all operations.
The assembly floor is organised by applying both short semi-automatic aggregates for assembling cylindrical and tapered bearings, and fully automatic assembly lines for assembling ball bearings.This equipment has devices for automated part delivery, accumulation of in-process stock, control, isolation of improper products, as well as washing and lubrication loading, thus minimising human influence on the process of assembling bearings.In the course of assembling, all bearings are subjected to the 100% operational control of key parameters in the automatic mode.Processes of marking and preparation for storage of bearings are also automated.
