Surface grinding machine

Surface grinding machine structure as shown in figure 3 - 54 for horizontal spindle and rectangular table surface grinder figure shape. This kind of machine tool grinding wheel spindle is usually by inside even type asynchronous motor direct drive. Usually is the spindle motor shaft, the stator of the motor is installed in the grinding wheel rack 3 housing, grinding wheel rack can be made along the slide 4 dovetail guideway 3 intermittent traverse movement (for The manual or hydraulic, slide along the column with grinding wheel rack 3 4 5 guide for the vertical cut into the intermittent movement ( Manual) Table 2 longitudinal reciprocating motion along the slideway of lathe bed 1 ( Hydraulic drive) 。 China's production of horizontal spindle and rectangular table surface grinder is divided into ordinary precision and high accuracy. Using normal level precision machine tool after fine grinding, processing face locating datum parallelism of 0. 015 mm / 1000 mm, the surface roughness Ra of 0. 32 ~ 0. 63μm； After fine grinding, the machine use high precision level parallelism face positioning reference to 0. 005 mm / 000 mm, the surface roughness Ra is 0. 04 ~ 0. 01μm。 The type of surface grinding machine surface grinding machine grinding, the workpiece mounted on magnetic chuck worktable, suitable for small and medium-sized steel or cast iron parts processing plane, after grinding workpiece on the remanence, demagnetization. More than a highly consistent when grinding, grinding good rigidity, easy to operate, high productivity. The plane of the surface grinding machine for grinding various parts. According to the grinding wheel face is different, can be divided into surface grinder with grinding wheel rim ( Circumference of a circle) For grinding and grinding wheel face. With grinding wheel rim grinding surface grinder, grinding wheel spindle is often in a horizontal position; With grinding wheel face grinding surface grinder, grinding wheel spindle are usually vertical. Depending on the shape of the table surface grinding machine and can be divided into two categories, rectangular and round table table. Therefore, according to different grinding wheel face shape and workbench, the normal surface grinding machine can be divided into four categories: horizontal spindle and rectangular table surface grinder, Figure 3 - 55 ( a) ) ; Vertical shaft torque table surface grinder, Figure 3 - 55 ( b) ) ; Horizontal spindle surface grinding machine with rotary table type ( Figure 3 - 55 ( c) ) ; Vertical frustum of a cone type surface grinding machine ( Figure 3 - 55 ( d) ) 。
