Features

It is applicable for grinding crank journal of auto, tractor and diesel engine repairing. In addition, it is fit for common cylindrical grinding. Rapid advance and retreat of tool wheel slide and longitudinal motion of working table are all hydraulic driving. The machine tool is armed with safe interlocking structure. As to crank processing, rotating switch to “crank”, when the wheel slide is at state of retreat, the working table is only manual drive. When grinding common workpieces, the working table is of longitudinal motion with hydraulic driving and its speed can be adjusted steplessly. Feeding of wheel slide can be transmitted by hand wheel. Machine Features: Workpieces are gripped by center or chuck and driven by headstock motor, grinding manually.Application of both manual and hydraulic transmission methods to realize longitudinal motion of the working table.Workpieces, grinding wheel, cooling pump and oil pump and oil pump are all driven by single motor.Rapid advance and retreat of wheel slide is driven by hydraulic. Safety feature:Electric interlocking structure of working table and wheel slide ensures safety in failure of adjusting and grinding.Wheel slide comes with reliable protection cover.
