The semiautomatic machines are intended for grinding of smooth, stepped, conical and shaped surfaces of bodies-of-rotation type by method of plunge-cut or through-feed grinding. Workpieces of cast iron, steel, non-ferrous metals and their alloys before and after heat treatment, as well as workpieces of various nonmetallic materials with the corresponding selection of abrasive tool and work rest blade ma-terial are being ground. The special automatic machines can be produced on the base of the semiautomatic machines equipped with loading-unloading devise.

Structural features:
- Arrangement of the machines: BCA-180B NC2 with stationary wheelhead; the rest of the machines of above range are with movable wheelhead and work-head.
- High productivity, accuracy treatment and quality of workpieces surface are provided by availability of reliable and precision spindles: the working spindle is in high-precision antifriction bearings, the grinding spindle is in hydrodynamic bearings.
- Feed of grinding wheel on the workpiece with the compensation of re-movalling of abrasive layer when dressing, as well as minor setting-up are pro-vided by electromechanical mechanism of feeds with the servodrive (except of BCA-180B NC2).
- The machines are equipped with systems of automatic dressing of grinding wheels (except of BCA-180B NC2).
- Availability of programmable controller with the electronic operator s panel enables to carry out monitoring and controlling of operation of the machines efficiently.
- The machines are completed with the "SIEMENS" and "MITSUBISCHI" control systems and electric drives in consultation with the Customer.
