Product Description

 

1. The connecting between the chuck and main shaft complies with the national standard (short cylinder connecting mode),so users only need to prepare right connection flange compatible with the machine tool and chuck instead of changing the machine tool structure during installation.
2. The whole installation process is quite easy. The chuck boady is the cylinder, with piston and inverted valve inside to achieve super-long time pressure-keeping function(more than 24 hours). The clamping and lossing movement is achieved by rotary air inlet at the side.The machine will not work before cutting off the gas supply.
3. The chuck boasts advantages of less weight, big hole diameter, high stroke and high rotating speed, which is applicable for lathe, pipe thread machine tool and welding equipments.
