GD-12S High Precision Centerless Grinding Machine

Main Features
1, The Ontology
Ontology and nine components by m han with FC - 30 senior cast iron moulds.By artificial normalizing heat treatment, natural aging treatment after more than six months, nine processing components using YASDA, MITSUI SEIKI, TOSHIBA, ELB world-class equipment such as a clamping processing, precision can reach micron grade, to ensure that the equipment foundation components and high precision.

2, Main Shaft System
Main shaft is made of SNCM - 21 h alloy steel, after tempering, carburizing heat treatment then through computer control cryogenic treatment, the surface hardness of HRC - 62 ° above, unilateral effective hardening layer of more than 1.5 mm.FX - 12 s main shaft with dynamic pressure oil film bearing spindle.

3, Wheel Drive Adjustment System
Adjust wheel spindle drive Motor with Japan yaskawa Servo Motor (YAS KAWA) Servo Motor, FX - 12 s speed control 0 ~ 320 RPM nc, to adjust to the best linear velocity, when adjusting wheel diameter changes can still keep the same linear velocity, grinding out the best products.
Servo motor installed on the adjusting wheel box clever design using direct drive synchronous belt, can adjust the wheel in the grinding with play Angle at the same time, guarantee the two pulley parallel all the time, overcome the old type centerless grinding machine with chain more section is produced by the inertia loss and the chain Angle bring many adverse effects, and often to avoid the change chain and zipper spring.

4, Spindle Oil Circulation System
Spindle automatic lubrication cycle oil (advanced spindle oil 10 #) and hydraulic shaping device for the same pump, external fuel tank, convenient cleaning oil change, spindle oil, two circulating oil filtering equipment filter and equipped with a pressure controller, ensure the life of the spindle.
