Big Stroke Front Mounted Pneumatic Chuck for Pipe Thread Machine
and Welding Equipment
1. Description
We are a company specializing in the production of chucks, like
self-centering chucks, power chucks and laser cutting chucks.
Accessories for CNC lathe are also provided. We have our own
R&D team to research and design the sructure of chucks
independently.
This kind of chuck is front mounted pneumatic chuck and is widely
used in lathe, pipe thread machine tool and welding equipment.
Because the connecting between the chuck and main shaft complies
with the national standard(short cylinder connecting mode), there’s
no need to change the structure of the lathe and just only prepare
the matching flange which can connect to the chuck and machine tool
when installing.
It is easy to install the chuck.The chuck body is the cylinder,
with piston and inverted valve inside to achieve super-long time
pressure-keeping function (more than 24 hours). The clamping and
loosing movement is achieved by rotary air inlet at the side. The
machine will not work before cutting off the gas supply.
