Versality

They should be useful for a variety machining operations and be as low as possible to reduce vibration and avoid coming into contact with the machining path.
(Stephen F. Krar,Arthur Gill,Exploring advanced manufacturing technologies,p. 4-1-1)


Automated Pallet Cell

The automated pallet cell(APC) is an ideal machining and workholding solution to maximize productivity and profit.The horizontal machining center with an APC allow parts to be machined in less time, reducing cost as well as reducing inventory.Workpieces are easily loaded and unloaded at an off-line station.Pallets can be manually indexed, allowing acces to all sides of the fixture for part load and unload.

Self Centering Chuck

Chucks are designed to move all jaws equally and simultaneously to center the part
in the chuck.Self centering chucks normally have higher gripping forces and are more
accurate than other chuck types.These chucks are recommended for bar stock, forgings,
castings, or turned parts that are located from gripping diameter.Some Self centering
power chucks are equipped with centrifugal force counter balance that maintain the
gripping force at high speeds.

Power Chucks

power chucks are essential part of the automatic manufacturing process. Power chucks provide an even gripping force and their performance does not rely on the skill of the operator. The gripping power is provided by hydraulic or pneumatic cylinders that cause the chuck's jaw to increase their grip on the work piece before the machining force can cause the workpiece to slip out.
