Comprehensive understanding of high-precision double-end grinding machines and solutions to their machining problems


  High-precision double-face grinding machineIt is a high-efficiency plane processing machine tool, which grinds two parallel surfaces at the same time in a processing process. According to the structure can be divided into horizontal and vertical, according to the feeding mode can be divided into penetrating, rotary and reciprocating. Due to its high precision and high production efficiency, grinding products are widely used in many industries such as automobiles and motorcycles, bearings, and magnetic materials. Valve gaskets, piston rings, cross shafts, connecting rods, compressor slides, hydraulic pump blades, shift forks, valve plates, stators, rotors, bearing inner and outer rings and rollers, magnetic steel plates, magnetic rings, Graphite plates and other products are suitable for processing.

High-precision double-end grinders will have some problems during the working process. During the operation of the double-end grinder, if there is no good technical support, it will not be able to effectively manufacture better workpieces. Of course, high-precision double-end grinders also have many characteristics, and the characteristics of double-sided grinders are mainly manifested in their production efficiency.

  High-precision double-face grinding machineThe production efficiency is high, and the time required for processing parts mainly includes two parts: mobile time and auxiliary time. The variation range of the spindle speed and feed speed of the double-sided grinder is larger than that of the ordinary machine tool, so it is possible to select favorable cutting parameters for each process of the double-sided grinder. Due to the good structural rigidity of the double-sided grinder, it allows strong cutting with a large cutting amount, which improves the cutting efficiency of the double-sided grinder and saves the maneuvering time. The moving parts of the CNC machine tool move quickly during the empty stroke, which hurts the clamping time of the workpiece. The tool can be replaced automatically, and the time is greatly reduced than that of ordinary machine tools. 1. Through the program setting of the numerical control system, rough grinding and fine grinding can be realized. 2. It can change with the decrease of grinding wheel diameter, and has the functions of automatic compensation of grinding wheel correction and error compensation of ball screw clearance. And the corrected position compensation function; 3, the system setting unit is 0.1m, which can display the grinding parameters of the grinding wheel; 4, the use of linear motor, dynamic balance and other technologies greatly improve the efficiency of the machine tool.

  High-precision double-face grinding machineTreatment of common problems: The grinding process is the process of extrusion, friction, plowing and debris separation of abrasive particles on the surface of the workpiece. The whole process is accompanied by the friction of the abrasive particles on the surface of the workpiece, especially the double-end grinding process, the friction resistance becomes larger, the grinding area is large, the heat generated by friction increases, and the temperature is high. The high temperature generated by friction is also concentrated in the place where the abrasive particles gather, which causes the local metal structure on the surface of the workpiece to anneal and shrink, forming a concave shape, making the surface color purple and causing grinding damage. To solve the grinding damage, the key is to choose the right grinding wheel. The grinding wheel should have the right hardness, not only have a strong self-sharpening, but also can not wear too fast, reduce the friction resistance generated during grinding. Secondly, the grinding wheel must have good chip removal performance, and the cutting fluid must be sufficient to play a better cooling effect. Also, if the grinding is only slightly damaged, the speed of the grinding wheel can be appropriately reduced, the cutting force can be reduced, and the problem of workpiece damage can be solved.

The above is the high-precision double-end grinding machine related content is introduced.
