HZ-KD series CNC gantry guide rail grinder is a kind of guide grinding machine developed for machine tool industry. It is suitable for grinding machine guide rails such as bed, workbench, beam, trawling plate and column. The series of products have formed a series of grinding width 1000mm-2000mm, grinding length 2000mm-8000mm, grinding height of 600mm-1000mm.

■ The gantry layout is adopted, and the closed frame structure is composed of bed, double columns and beams. The bed and worktable adopt double V-type self-aligning guide rail pair (HZ- KD2010 adopts flat-v-type guide rail); the worktable guide rail is stick plastic guide rail.

■ There are two carriage on the crossbeam, which are respectively equipped with peripheral grinding head and universal grinding head. The double grinding head moves up and down vertically along the guide rail of the carriage, and the carriage moves horizontally along the guide rail of the crossbeam. Both peripheral grinding head and universal grinding head are equipped with wheel dresser.

■ The vertical movement of the worktable is driven by hydraulic pressure, which can be stepless speed regulation, smooth movement, and oil temperature control device.

■ Vertical feed, transverse feed movement of peripheral grinding head and feed movement of grinding wheel dressing; The vertical feed, transverse feed and rotary indexing motion of the universal grinding head are all driven by the AC servo system, and each feed shaft can be used for fast feed movement or intermittent feed movement.

■ It can realize both automatic grinding cycle controlled by program and manual grinding cycle controlled by electric hand wheel.

■ With modular design, the worktable can be increased by one meter. According to the special requirements of users, the following functions can be added: spindle motor frequency control; concave convex grinding; CNC shaft full closed loop control; grinding wheel online dynamic balance, etc.
