Surface-grinding machines

Example of horizontal spindle flat surface grinder with long table

Grinding the flat surfaces of parts and blanks.

Engineering company ENCE GmbH offers various ancillary equipment for metallurgical productions and metalworking, including machining facilities, these are millers, lathes, drilling equipment, grinders (roll-grinders and flat surface grinders).

Differential characteristic of flat surface equipment supplied by the company ENCE GmbH is heavy machining. The flat surface grinder design and grinding head feeding movement with zero-backlash, ensured by recirculating ball screw and nut in vertical movement of the grinding head of the machine, secure big surface high-precision machining. Flat surface grinders are equipped with an automatic lubrication system and abrasive dust protection.

Flat surface grinders have a stand-alone control panel. The whole grinding process is automated. High vibration resistance and rigidity of the flat surface grinder structure guarantee high machining accuracy.

Application sphere of a flat surface grinder: grinding of flat surfaces of workpieces and parts in various production conditions.
