NAME: Crankshaft Grinding Machine --- Hydraulic worktable
MODEL: MQ8240/1000
To introduce: Model MQ8240 is designed for grinding the crank journal and main journal of the crankshaft in several industries like automobile, truck and diesel engine as well as for external grinding.
--- In the process of operation, pieces to be ground are clamped tightly by specific tools and then via the grinding part driven by the motors mounted on the front-frame.
--- The work-bench is driven by either manual or hydraulic pressure to move to and fro vertically. The mechanical –driving unit is powered by motor.
--- The grinding wheel , work-bench, cooling –pump and oil-pump are driven by motor independently
--- Advanced plastic-coated guiding rails are adopted to support the moving machine table, proven to be reliable and secure.
--- The frame of the grinding wheel is driven hydraulically .
