Surface Grinding Machine
Main Features and Performance:
The Series 71 Horizontal-Spindle, Rectangular-Table Surface Grinder utilizes a cross-slide layout for models with a table width of 400 mm or less, while models with a table width exceeding 400 mm employ a moving-column layout. Its primary function is to grind the flat surfaces of workpieces using the periphery of the grinding wheel; additionally, the face of the wheel can be utilized to grind vertical surfaces or grooves on the workpiece.This type of surface grinder is suitable for machining rectangular tables, steel-insert guide rails, and cemented carbide components, as well as for the precision machining of various other parts.
