Many different types of grinding machines, there are surface grinder, cylindrical grinder, internal grinder, universal cylindrical grinding machine (which can also grind the hole), gear grinding, thread grinding machine, rail grinding, centerless grinder (grinding cylindrical) and tool grinder (grinding stone) and so on. Here are surface grinder and its movement.
1. Surface grinding machine structure (in M7120A for example, where: granite - grinding machine category; 71 - desktop surface grinder horizontal spindle and rectangular; 20 - working table width 200mm; A - the first major improvement.)
(1) wheel rack - Install wheel and drive wheel for high-speed rotation, the wheel frame can slide along the dovetail guide for manual or hydraulic lateral clearance campaign.
(2) slide - Installation of wheel and drive wheel frame rail up and down movement along the column.
(3) column - bearing slide and wheel frame.
(4) table - install a workpiece driven by the hydraulic system for reciprocating linear motion.
(5) bed - supporting table, install the other components.
(6) coolant system - to provide coolant to the grinding zone (saponified oil).
(7) hydraulic drive system - its components are: 1) dynamic components - the pump, oil supply pressure of hydraulic system; 2) implementation of the components - the fuel tanks, and other parts of table driven movement; 3) control components - for a variety of valves, pressure control, speed and direction; 4) Auxiliary components - such as tanks, pressure gauges and so on.
Hydraulic and mechanical transmission compared with the smooth transmission, can overload protection in a large range of stepless speed regulation and so on.
2. Plane Grinding Movement
(1) The main sports - high-speed rotating wheel.
(2) the feed movement 1) vertical feed - Table driven parts of the reciprocating linear motion; 2) vertical feed - the depth of the direction of wheel movement to the workpiece; 3) cross feed - wheel movement along the axis of the gap.
