There are many varieties of precision surface grinders, including three-dimensional grinders, cylindrical grinders, internal grinders, all-weather cylindrical grinders (can also grind internal holes), cone grinders, fingerprint grinders, rail grinders, unintentional grinders (grinding outer cylindrical grinders), machine grinders (grinding machine tools), etc. There you will be introduced to the three-dimensional grinder and its activities. 1. Three-dimensional grinder structure (taking M7120A as an example, which: M - grinder tools; 71 - horizontal axis rectangular bench grinder; 20 - The width of the task table is 200mm; A - The first serious improvement. (1) Weight frame - the weight is installed and the sand is connected to the high-speed winding, and the weight frame can be moved manually or hydraulic transverse clearance along the sliding seat dovetail rail. (2) Slide seat - install the weight frame and pull the weight frame along the column rail for high and low activities. (3) Column - supporting slide seat and weight frame. (4) Task table - device workpiece and hydraulic fragment drive to and from the back and forth curve activity. (5) Bed body - supporting task table, device and other components. (6) Fragmentation of icing liquid - Icing liquid (saponification oil) is required for the grinding area. (7) Surface grinder hydraulic transmission fragmentation - its components are: 1) energy components - oil pump, supply hydraulic transmission fragmented pressure oil; 2) Execution parts - oil cylinders, pulling task tables and other components; 3) Master the components - for various groups of valves, master the pressure, progress, position, etc.; 4) Auxiliary components - such as fuel tank, pressure gauge, etc. Precision surface grinder Compared with the machine transmission, the hydraulic transmission is bumpy in the transmission, and the surface grinder can cover the overload and complete the advantages of stepless price adjustment in a large area. 2. Three-dimensional grinding activities (1) The main activity - the high-speed winding activity of the weight. (2) Feeding activity 1) Longitudinal feed - the task table opens the round-trip curve activity of the workpiece; 2) Vertical feed - the weight moves to the depth of the workpiece; 3) Lateral feed - the weight moves along its axis gap.
