Emergency Collets Provide Specialized Workholding
Hardinge's three 16C emergency collets fill the need for stepped, oddly sized or specially shaped collets.
Hardinge's three 16C emergency collets fill the need for stepped, oddly sized or specially shaped collets. The emergency collets feature 1/16" pilot holes and internal threads for positive stops. According to the company, the collets’ soft faces and small pilot holes enable rapid drilling, boring or stepping out to the exact size required. Pins are supplied with each collet for precise machining.
The emergency collets are offered in standard lengths, such as the 16C E-4 emergency collet, or with extended noses for deeper counterbores and better work clearance. The 16C EN2-4 and the 16C EN1-4 provide 1/2" and 1" straight out extended noses, respectively.
A non-woven porous material with a special coating enables vacuum chucks and tables to hold sheets of metal and other materials more effectively on CNC routing machines. The material, called Vilmill, is used as a substrate between the sheet or plate material to be machined and a suitable vacuum table or vacuum chuck where it is held securely in place by the vacuum.
These vise jaws use protruding, mechanical pins to repeatedly support workpieces either horizontally or at angles. They are said to allow quicker setups than conventional parallels.
Affordable indexers and fourth-axis rotary tables greatly enhance the capability of vertical machining centers. It’s almost as good as having a horizontal machining center.
