CBN valve stem end grinding machine
Valve rod end grinding machine (TS-DY-200B)
1. Processing range (original state of the workpiece):
2. Machining accuracy and beat:
Detection method and tool
MAX 0.02mm continuous machining and measuring 50 pieces
±0.03mm continuous machining and measuring 50 pieces
Special inspection tool + vernier caliper
Continuous processing and measuring 50 pieces within Ra0.8μm
With a machining allowance of 6.2 as standard within 6s/pcs
3. Main configuration:
Main structural features
It is cast from high-strength cast iron and then annealed to prevent deformation. The symmetrical structure design greatly improves the rigidity, vibration resistance and thermal deformation resistance of the bed.
Jin Fuling three-phase asynchronous motor 2.2KW (380V/50Hz) Y90L-2 (IP54)
Drive ribbed belt
8PL920 cushioning, vibration absorption, stable operation, low noise
Grinding wheel spindle: Angular contact bearing with mounting spindle (3000RPM), introduced in Taiwan.
Ceramic CBN, no need to trim
1. Grinding wheel service life: with the processing rod diameter of 6.2mm as the standard, 100000 pieces / piece or more
2. Spindle service life: above 30000Hr, no loss of precision
Grinding wheel specifications
Taiwan silver ball screw
Market standard parts configuration, smooth sliding resistance, high sensitivity, low noise; repeat positioning accuracy: 0.01mm
Taiwan silver roller linear guide
Huichuan servo + motor
The main shaft adopts sealed self-lubricating and must be filled with high-temperature grease; the feed is automatic lubrication oil pump, fixed point, timed and quantitative automatic lubrication. When the automatic oil filling pump is out of oil, the automatic operation stops, the alarm flashes promptly, and the refueling is forced.
Huichuan Programmable Controller (PLC)
1. The electrical part should have certain moisture and dustproof measures to adapt to the environment of 70% humidity work site in summer.
2. There are total accumulated numbers on the operation panel, the cumulative number of shifts, the clearing, and the production timing function.
3. The machine has a computer RS232 interface, with alarm signals, counting alarms and fault alarms.
4. The device is clearly positioned as a three-color signal light.
Huichuan 7-inch screen
Air pressure configuration
Connect the switch, open the door and stop
50L/min. High-pressure pump auxiliary and one-way valve control supply quickly, cold-worked workpiece and grinding wheel clearance
Fully enclosed protective cover, grinding wheel shield spoiler
Oil mist collector, powder centrifuge, filter water tank
Pneumatic automatic feeding, product spacing does not collide
Pneumatic automatic discharge, product spacing does not collide
Three-phase five-wire system 380V/50Hz, air pressure: 0.4~0.6MPa
