Low Distortion - because the special indentations give a very secure grip, less chuck gripping pressure is required to securely hold the part. Typically grippping pressures can be reduced to one tenth of normal requirement. This means greatly reduced distortion especially on thin-walled parts. | |||
|
Fewer
Machining Operations - lower distortion means improved roundness
of bores and diameters such that a final turning or cylindrical
grinding
operation can be avoided. |
|||
 |
Less Material Wastage - parts only require 5mm depth of grip for secure and stable holding compared to the 20mm to 25mm required with other jaws. On a 100mm diameter steel part, saving 20mm on the depth of grip results in a material cost saving of about £0.50p per part. | |||
 |
Good Repeatability - the precise indentations allow the part to be removed from a chuck and re-inserted later with a repeatability of +/-0.005mm. Intermediate operations such as measuring are possible between roughing and finishing the part on the lathe. | |||
