A significant part of the company’s extensive machine pool consists of numerical control machines. There are more than 500 of them.
In recent years, completely new types of machines have been purchased, that meet the modern requirements of metalworking, new technologies and NC systems. Turning pool is equipped with modern NC machines with the processing center functions. Complex-profile parts are processed on them with simultaneous drilling and milling, both along the axis of the part and off the axis, with the accuracy of 8-10 tolerance grades.
Large turning and boring equipment is being replenished modern NC machines that are equipped with additional functions:
- Milling with the accuracy of 0.01 mm;
- Processing of holes, profile contours in different planes, thread cutting (maximum processing diameter up to 3,500 mm).
In milling processing, vertical processing centers are used (including portal), as well as horizontal machining center.
Some machines are equipped with a programmable turntable that allows for processing of complex body parts on five sides with high concentration of technological operations with the accuracy of 0.01 mm. Complex five-axis processing by methods of power straight and contour milling, drilling, countersinking and boring on NC machines.
It is possible to process blanks with a maximum size of 1,800×2,000×1,400 mm, weighing up to 8 t, using up to 60 purchased cutting tools. For high-speed machining, processing centers are used with the accuracy of 0.005 mm. For grinding operations, grinding NC machines are used. The company introduced electric erosion processing that continues to evolve due to the purchase of new modern machines.
