Product Introduction
The double disc grinding machine is suitable for grinding parts of various shapes and different materials on the upper and lower surfaces, especially parts with high requirements for verticality, flatness and parallelism, such as bearings, pistons, stamping parts, cam pieces, piston pins, rollers, ceramic parts, etc. The grinding head of the double disc grinding machine adopts a V-shaped steel inlaid needle bearing guide rail, and the grinding is realized by integral movement. The rigidity of the double disc grinding machine is improved to the maximum extent due to the non spindle telescopic grinding. The spindle adopts the combination of double-row short cylindrical bearings and angular contact ball bearings, so that the cutting depth is large and the precision is high
Features and benefit
1. The spindle of double disc grinding machine is made of 40Cr material, has undergone forging, annealing, normalizing, quenching and tempering, high frequency quenching and stability treatment.
2. The guide rail of the double disc grinding machine is made of Gr15 material; The inlet and outlet plate are made of 65Mn material; Feeding adopts high-precision ball screw assembly.
3. The spindle of the double disc grinding machine has no spline and does not do telescopic movement. The concentricity of each bearing hole in the spindle box is ensured by a special processing technology so that the mechanical internal friction is very small. Then finally the machine achieves a different output power with the same power input.
4. The dresser of the double disc grinding machine is of an integral structure and belongs to a separate dressing system, one dressing arm and two grinding wheel are simultaneously dressed, so that the stability is good, the dressing precision is high. The swing arm are divided into two processes of coarse dressing and fine dressing, and automatic dressing and automatic compensation are realized.
5. The grinding of the double disc grinding machine realizes hydraulic inching and automatic compensation; Automatic lifting and lowering of the grinding wheel’s protective cover, with grinding wheel limit protection; Safety interlocking between action of the lifting - lowering the grinding wheel’s protective cover and the rotation of the grinding head; Correction and grinding interlock safety device. High degree of automation and high factor of safety.
6. Both the feeding and discharging guides of the double disc grinding machine adopt sleeve-type sliding. The feeding and discharging plates are adjusted by internal bolts which can be tightened through external screws. The feeding and discharging plates can be adjusted in the horizontal and vertical directions. The adjustment is convenient and the operation is simple. It fundamentally overcomes the problems of difficult adjustment, low efficiency, large size change and low precision.
