2. Standard accuracy of machine tool:
After the centerless grinder grinding (through grinding) of Hotman Company, the following standard accuracy requirements must be met: (Different grinding wheels should be used for different materials).

No.	Grinding mode	Work piece size (MM)	Flatness	parallelism
1.	Through grinding	Standard sample	≤0.001mm	≤Ra0.1
2.	Entry grinding(press grinding)	Standard sample	≤0.002mm	≤Ra0.2

Note: Rough grinding (generally grinding amount 0.05~0.25mm); Fine grinding (generally 0.005~0.02mm).
3. Device description:
(1) Ontology
The body and components are cast with high-grade cast iron FC-30, which is artificially normalized heat treatment and then subjected to natural aging treatment. Component processing adopts YASDA, MITSUI SEIKI, TOSHIBA, ELB and other world-class equipment for one-time clamping processing, precision size up to micron level, to ensure the high precision of the basic components of the equipment.
(2) Spindle system
The main shaft adopts the Perrin type spindle, before and after the double support structure, after tempering, carburizing heat treatment and then by computer controlled cryogenic treatment, the surface hardness of HRC-62° above, one side of the effective hardening layer up to 1.5mm above, the main shaft adopts the bearing structure, independent lubrication and heat, the two ends of the support assembly, the runout is less than 0.002mm.
(3) Adjust the wheel drive system
Adjusting wheel spindle drive adopts servo motor, speed control 0-250rpm(digital control) can be arbitrarily set speed, adjust to the best linear speed, when adjusting wheel diameter changes still can maintain the same linear speed, grinding out the best product.
  The servo motor is cleverly designed and installed on the adjusting wheel box and directly driven by the synchronous belt. It can hit the tilt Angle with the adjusting wheel at the same time during grinding to ensure that the two belt wheels are always parallel. It overcomes many adverse effects caused by inertia loss and chain Angle caused by chain multi-segment transmission of old centerless grinder. And eliminates the need to constantly change chains and zipper springs.
(4) Double V track structure
Double V-shaped guide rail structure, the surface through the manual precision shovel, uninterrupted automatic lubrication, to ensure the accuracy and precision of feed.
(5)  Sand repair system
The cross structure two-axis servo automatic sand repair system is adopted, and the two-axis linkage interpolation sand repair is realized through the numerical control system, and the molding and cutting grinding of the workpiece with taper and radian is realized. Sand repairing device adopts dovetail groove pure hand-shoveling structure, sand repairing mechanism and grinding wheel seat separate design, to ensure the precision and stability of dressing device.

(6)  Circuit system
The circuit of the whole equipment adopts Beijing Schneider circuit system, beautiful and durable, good operation. Increase the height of the electric box, and equipped with air conditioning cooling device, convenient operation at the same time, more conducive to the circuit system heat dissipation.
(7) Numerical control system
Hotman secondary development of numerical control system, Chinese man-machine dialogue interface, easy to learn; With corresponding brand servo motor, one axis automatic feed, two axis CNC molding sand repair, good compatibility, accurate feed.
