WHY GRINDING MACHINE BHC CNC?

The universal BHC CNC is a fully CNC controlled center grinding machine with a controlled axis X (grinding wheel head in-feed), Z (longitudinal table feed), and a controlled axis C (grinding wheel peripheral speed).

The BHC universal grinding machine is designed for external and internal grinding of workpieces clamped between the centers or clamped in the chuck. The feed-in of the grinding wheel head and the table are realized by servomotors and ball screws. The BHC grinder is a very stable and precise machine that can be used in series production as well as in single-part production for workpieces up to 5 000 kg.

The machine grinds in working accuracy IT 4 and can be equipped with modern design features, as for example rolling bearing of the grinding spindle or hand scraping guideways with Teflon pads for minimal adhesion (stick-slip effect). In addition, the machine can be upgraded with an in-process gauge, axial probe, automatic (electric) steady rests, CNC rotary dresser, electric spindles, Z-axis encoder, etc.

The machine can be installed with, SINUMERIK 828D sl, SINUMERIK 840D sl, SINUMERIK ONE or FANUC control system.

The grinder is designed primarily for numerically controlled grinding of external cylindrical surfaces of various diameters and their neighbouring faces and radius. So called sweep cones may be ground by interpolation between axis X and Z. Grinding wheel head is mutually rotational. It enables vertical plunge-cut grinding using work head swivel. This method may be particularly used for grinding steep cones and simultaneous grinding of cylindrical and face surfaces of workpieces. A folding device with a separate spindle is used for internal grinding.

In the special version, the machine is equipped with a C axis for precise positioning and grinding of non-circular shapes, a stiffer clamping spindle or a polishing device for high surface quality. These superior features make the machine the most versatile and efficient solution on the grinding machines market.
