Semi-precision and finishing of various planes with high appearance quality requires a conventional planar grinding method. The machine tool for plane grinding is a planar grinding machine, and the outer surface of the grinding wheel can be applied, and the end face can be used. 1. The primary type and motion are elected as a grinding wheel peripheral grinding method, the grinding machine spindle is in the horizontal layout; when the grinding wheel end face grinding method is selected, the grinding spindle is in the formation layout. When planar grinding, the workpiece can be mounted on a rectangular working table for a backward movement, or on a circular workstay for circumferential motion. According to the combination of spindle layout and workbench shape, the general plane grinding machine can be divided into the following four categories: (1) Inlet torque table plane grinding machine (Fig. 1A) In this machine, the workpiece is sucked by a rectangular electromagnetic job stage. The grinding wheel is rotated mainlight N, the working table is longitudinally reciprocating f1, and the grinding wheel frame is bracketing vertical cutting movement F3 and the lateral feed moving F2. (2) Shax Mountain Table Planar Grinder (Fig. 1B) In this machine, the grinding wheel is rotated from the main motion N, the rectangular operation stage is longitudinally reciprocating f1, and the grinding wheel frame is intermittently cut into motion F2. (3) Vertical shaft round plain plane grinding machine (Fig. 1C) In this machine, the grinding wheel is rotated as a rotation of the main moving circular work table rotating as a circumference feed moving f1, and the grinding wheel frame is intermittently cut into motion F2. (4) The lying shaft round plain plane grinder (Fig. 1D) In \u200b\u200bthis machine, the grinding wheel is rotated from the main motion N, the circular work table rotates as a circumference feed moving F1, the grinding wheel frame is connected to the radial feed moving moving movement F2 and intermittent Vertical cut into exercise F3. In addition, the rotary centerline of the working table can be adjusted to the skewing orientation to grind the tapered surface. In the above four planar grinding machines, the planar grinding machine grinding with a grinding wheel is often larger than the grinding wheel diameter of the end surface, which can abrasive the full width and grinding area of \u200b\u200bthe workpiece with the grinding wheel diameter of the end surface. Larger, so the productivity is high. However, when the end face grinding, the outer surface of the grinding wheel and the workpiece is a curved wire or a surface touch, the touch area is large, the cooling is difficult, the chips is not easy to remove, so the processing accuracy and the outer surface roughness are slightly poor. The circular table planar grinder compared to the rectangular plane grinding machine, the productivity of the circular table is slightly higher, which is due to the circular table, and the torque stage has a reversal time loss. However, the circular table is only suitable for grinding small parts and large diameter annular parts and cannot grind the length of the length. Momential places can easily grind a variety of commonly used parts, including annular parts having a diameter less than a substantial width. Now, much is used, the lying angle torque platform plane grinding machine and vertical shaft round serial plane grinding machine. 2. The beef ruster plane plane grinding machine is a substantial plane grinding machine as shown in Figure 2. The main shaft of this machine tool is usually directly driven by an internal connection asynchronous motor. It is often a spindle, and an electric stator is attached to the body shell of the grinder 3. The grinding wheel frame 3 can be moved in a batch lateral feed (manual or liquid) along the swallow tail guide of the slide 4. The slide holder 4 and the grinding wheel frame 3 are permitted in the guide rails of the column 5 (manual). Workstat 2 along the guide rail along the bed 1 (Hydraulic Transmission).Nowadays, the processing quality of the layered torque of the torque produced in my country is: General precision level: After the test piece is refined, the surface of the process faces 0.015mm / 1000mm, the outer surface roughness Ra \u003d 0.32 ~ 0.63um; High-precision level: After the test piece is refined, the surface of the process faces is 0.005mm / 1000mm, the outer surface roughness Ra \u003d 0.04 ~ 0.01um.3.The vertical axis round counter planar grinding machine is shown in Figure 3.The spindle of the grinding wheel frame 1 is also directly driven by an inner contingent motor.The grinding wheel frame 1 can be moved in the guide rail of the column 2.The circular workstation 4 rotates as a circular feed movement.In order to facilitate loading and unloading, the circular workstay 4 can also move longitudinally along the bed.Since the grinding wheel is large, the insert grinding wheel is used.This grinding wheel bristles the cooling liquid into the cutting to make the grinding wheel easily.This type of machinery productivity is recommended for batch production.
