- Category : Industrial Machinery
- SKU : 1601211856980
Crankshaft grinding machine MQ8260BX1600
MAIN STRUCTURE：
A, The machine is controlled by mechanical, electric, hydraulic means; operated mainly by hand.
B, Left and right chucks of basic model are crisscross and adjustable, which can improve the efficiency of loading and adjusting workpiece.
C. The workpiece rotated by the workhead motor can be either between centers or on chucks and is ground by manual feed.
D. Power-driven is actuated by motor, which is used for jump displacement or adjustment.
E. Max. adjustment of left and right chucks in vertical is 110mm, in cross is 2mm; The chuck can realize micro-rotation from 0°to 30°.
F. Workpiece, wheel, work-table, coolant pump and oil pump are driven individually by separate motors.
G. Worktable and wheelhead is designed with hydraulic and electric interlocking mechanism, and the accident caused by mis-operation can be prevented whether in adjustment or grinding.
