2. Driving gear is installed into the frame and gear is immersed in oil reservoir. Customer could choose Electromagnetic governor. which is stepless speed regulation within a certain range and enlarge the area of craf.
3. The press adopts hexahedral rectangle lengthen gib, which has high guiding precision and steady precision.
4.PLC from Omron electrical control system allows various auto-equipment reprogrammed accord-lng to different requirements and perform various functions,to ensure high reliability and high adaptability,
5. Use adopts dual valve from TACO, Japan, which can guarantee the safety and reliability of clutch.
6. Machine is with both hands button and foot switch to achieve continuous, single and inching practices.
7. Auto grease lubrication system,easy stroke adjustment mechanism increases press versatility tremendously.
8. Pneumatic dual balance cylinder, which balances the slide block and punch weight to reduce noise and impact;
9. The press adopts cam controller which be combined with proximity switch (Schneider) which will realize the synchronous detection and monitoring reliably.
