Double face grinding and centerless grinding is a kind of high efficiency grinding method, but it is a kind of grinding method which focuses on development. At present, double face grinding machine grinding is being paid attention to by production enterprises, and centerless grinding is basically applied by production enterprises, and its efficiency is very high. The high precision centerless grinder used in centerless grinding has better grinding effect. Double face grinding is also very promising. It is not only used in the metal field, but also in the non-metallic field.
Double end grinding machine is a kind of high efficiency plane machining machine, which can process plane products. In different cases, the double face grinder can grind two parallel end faces at the same time in one processing process. According to the structure, it can be divided into horizontal and vertical types, and according to the feeding mode, it can be divided into penetrating type, rotary table type and reciprocating type. Due to the high precision and high production efficiency of the grinding products, they are widely used in automobile and motorcycle, bearing, magnetic materials and many other industries. The products of piston, piston ring, valve washer, connecting rod, cross shaft, valve plate, fork, hydraulic pump blade, rotor, stator, compressor slide, oil bearing inner and outer rings and rollers, magnetic ring, magnetic steel sheet and graphite plate of electronic industry are suitable for processing. It turns out that part of the products that can be processed by a surface grinder in Taiwan can be transferred to a double face grinder for processing.
Compared with the flat grinding machine, the double face grinder has the following characteristics:
There will be some problems in the working process of double face grinder. If there is no good technical support in the operation process of double face grinder, it will not make better work pieces effectively
Of course, double end grinding machine also has many excellent characteristics, the excellent characteristics of double face grinder are mainly reflected in its production efficiency.
Compared with the surface grinder, its production efficiency is high. The processing time of double end grinder parts mainly includes two parts: mobile time and auxiliary time. The variation range of the spindle speed and feed rate of the double face grinder is larger than that of the ordinary surface grinder. Therefore, the most favorable cutting parameters can be selected for each working procedure of the double face grinder. Because of the good rigidity of the double end grinder, it is allowed to carry out heavy cutting with large cutting parameters, which improves the cutting efficiency of the double end grinder and saves the mobile time. The moving parts of CNC double face grinding machine have high speed of idle travel and short clamping time.
The characteristics of CNC system are as follows:
1. Rough grinding and fine grinding can be realized through the program setting of CNC system.
2. It can be formed with the decrease of the diameter of grinding wheel, automatic compensation of wheel correction, clearance error compensation of ball screw, and position compensation after correction;
3. The minimum setting unit of the system is 1um, and the grinding parameters can be displayed;
4. The use of linear motor, dynamic balance and other technical processes, greatly improving the efficiency of the machine tool.
Grinding workpieces: all kinds of metal or non-metallic material workpieces with double end faces to be precisely ground, especially thin-walled workpieces with high machining accuracy
1. Large quantities. Generally, the processing capacity is more than one million pieces.
2. Wide application. The grinding materials include cemented carbide, cast iron high speed steel, copper iron conforming material, magnetic material, ceramics, etc.
3. High machining precision. The general accuracy is flatness ≤ 2um; parallelism ≤ 3um; roughness value RA ≤ 0.2um
