2. Machine tool accuracy: 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 | ≤Ra0.2 |
2. | Entry grinding(press grinding) | Standard sample | ≤0.002mm | ≤Ra0.2 |
Note: Rough grinding (generally grinding amount 0.05~0.15mm); 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 is made of SNCM-21H alloy steel, after tempering, carburizing heat treatment and then computer controlled cryogenic treatment, its surface hardness up to HRC-62° above, single effective hardening layer up to 1.5mm above. FX-12CNC spindle uses dynamic pressure oil film bearing spindle.
(3) Adjust the wheel drive system The driving motor of the spindle of the adjusting wheel adopts Delta servomotor FX-12CNC to control the speed of 0~320rpm to adjust the optimal linear speed. When the outside diameter of the adjusting wheel changes, the linear speed can still maintain the same, ensuring the precision and finish of the machining workpiece, and grinding out the best products. The servo motor is skillfully designed and installed on the adjusting wheel box and directly driven by synchronous belt, which can be used to hit the tilt Angle with the adjusting wheel at the same time when grinding, to ensure that the two belt wheels are always parallel, which overcomes the inertia loss caused by the chain multi-section transmission of the old type centerless grinder and many adverse effects brought by the chain Angle, and avoids the frequent replacement of the chain and the zipper spring.(4) Main shaft circulating oil system Spindle automatic lubricating circulating oil (senior spindle oil 10#) and oil pressure dressing device is the same oil pump, external tank, easy to clean and change oil, spindle circulating oil through two oil filter devices and equipped with pressure controller, to ensure the life of the spindle.(5) Numerical control system: Hotman secondary development CNC system, Chinese operating interface, simple and easy to learn, with high precision servo motor, good compatibility, accurate feed!4.

7.Adjust the wheel drive system:The spindle of the adjusting wheel is directly driven by the servo motor synchronous belt. When the outside diameter changes, the speed can be adjusted to achieve the best linear speed to ensure the precision and finish of the workpiece. The tilt Angle of the pulley can be adjusted properly when grinding, so that the two pulley always keep parallel. It overcomes many adverse effects caused by inertia superposition caused by chain multi-segment transmission of the old centerless grinder, and does not need to change the chain and zipper spring often.8.Feed slideThe use of advanced casting materials, eliminate internal stress, high strength, low deformation affected by temperature difference.The contact surface through the precision manual shovel flowers, the slide through the lubrication system fully smooth, with strong wear resistance.Stable horizontal movement accuracy, grinding machining, feeding accuracy can reach μm level.Precision lead screwFeed screw with ball screw, high positioning accuracy. Excellent friction characteristics and reversible, can reach μm class positioning accuracy.Movement after sufficient lubrication, smooth movement. The contact surface of the track is scraped by manual, the movement resistance is small, and the accuracy of the machine can be maintained for a long time.9.Plant strength: Dongguan factory
