1. Surface grinder structure (take M7120A as an example, which: M - grinder type machine tool; 71 - horizontal axis bench top surface grinder; 20 - work surface width is 200mm; A - * major improvement.)
(1) Grinding wheel frame——Installing the grinding wheel and driving the grinding wheel to rotate at high speed, the grinding wheel frame can be moved manually or hydraulically along the sliding dovetail guide rail.
(2) Slider - Install the wheel frame and drive the wheel frame to move up and down along the column guide.
(3) Columns - support slides and grinding wheel frames.
(4) Workbench - The workpiece is mounted and driven by a hydraulic system for reciprocating linear motion.
(5) Bed body - support the workbench and install other components.
(6) Coolant system - supplies coolant (saponified oil) to the grinding zone.
(7) Hydraulic drive system - its composition is:
1) Power component - is the oil pump, supplying hydraulic transmission system pressure oil;
2) Actuator - for the cylinder, to drive the movement of the table and other components;
3) Control elements - for various valves, control pressure, speed, direction, etc.;
4) Auxiliary components - such as fuel tanks, pressure gauges, etc.
Compared with mechanical transmission, hydraulic transmission has smooth transmission, overload protection, and can realize stepless speed regulation in a large range.
2. Surface grinding motion
(1) Main motion - high-speed rotation of the grinding wheel.
(2) Feeding motion 1) Longitudinal feeding - the worktable drives the workpiece to reciprocate linear motion;
2) Vertical feed - the grinding wheel moves toward the depth of the workpiece;
3) Transverse feed - the grinding wheel moves along its axis gap.
Purpose: lock boxes, cabinets, doors, etc.
Features lock all-copper, shackle sturdy rustproof
