main / production /

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.
