1. Description
This product is a national patent product with independent
intellectual property rights.
The chuck itself is a cylinder with a built-in piston, and the
clamping and loosening actions are realized through the spindle
tail control mechanism. This product is a large diameter
wedge-shaped three-jaw through-hole, especially suitable for the
clamping of irregular objects. Sliding surfaces are hardened,
precision ground and directly lubricated. The advantages of this
product lie in its high rigid structure and high clamping accuracy.
Its advantages are: 1. High quality alloy steel, after special heat
treatment and surface nitriding treatment, higher strength, more
wear-resistant.
2. All mating surfaces are grinded by precision, with stable and
durable precision. Lubrication in place, long service life.
Products are suitable for gear processing, disk type, short shaft
type of workpiece processing.
In addition to standard size chucks, we also offer custom chucks
for CNC lathes, regular lathes and other equipment requiring rotary
lathes to be improved.
