Precision Mechanics Shop
Precision Mechanics Shop is a production unit of BIS LLC. It manufactures turned and milled precision parts.
It is located in an insulated room equipped with split systems in order to keep stability of temperature, which is very important for manufacturing of precision parts.
Precision Mechanics Shop has 4 highly-efficient CNC precision machines by OKUMA (Japan):
- OSP-P200LA CNC turning machines: LB 200 MC and LB 2000 EX MC
- OSP 200 MA CNC milling machines: two MB 46 VAE's
This equipment supports the manufacturing of any parts up to quality class 6 and degree of roughness 1,6 Ra of various materials: structural steel, stainless steel, duralumin alloys, copper, brass and bronze alloys, and various kinds of plastic (PTFE, Tecaform, nylon plastic, acryl).
