New pins alleviate need for external clamping

Dimac Tooling, a supplier of accessories and workholding solutions for CNC milling and CNC turning machine tools, is the exclusive agent for Mitee-Bite products and its latest offering, Modular XYZ Xpansion Pins.

The new Modular XYZ Xpansion Pins are designed for Tombstone, Grid Plate and Fixture Plate applications. The unique, patent pending design provides accurate location, repeatability and high holding forces for securing parts on the inside diameter.

Two types of pins are available, Press Fit and Threaded. Press Fit Pins are available in 1/4, 3/8, 1/2, 5/8, M6, M10, M12 and M16 diameters for custom applications and the Threaded version in standard sizes of 1/2, 5/8, M12 and M16 for tombstones and grid plates.

Manufactured from heat treatable 17-4PH stainless steel, the Pins expand up to 0.7mm and the diameter can be machined for specific applications.

The top of the Pins have a slight taper creating maximum line contact in bore and provides clearance during load/unload. The Pins are designed for quick set-ups on

secondary operations such as material coming off CNC lathes, prep stations, water-jets or applications outside machining centres.

Press Fit Pins are intended for press fit or close tolerance removable slide fit applications installed in a precision bore or a bushing with the centre threaded for the tapered screw. If precise location is not necessary, the pin can be used on top of the fixture plate. Mitee-Bite provides a simple tool to make installation and removal of the XYZ Pins quick and easy.

Threaded Pins incorporate an internal rotary broached hex for simple installation and removal from a tombstone, grid plate or fixture plate. Threaded Pins may be installed in a drilled and reamed hole for precise location or set in a hardened drill bushing for fixture strength and wear resistance.

“The XYZ Pin provides ‘out of the way’ workholding and accessibility to all work surfaces with absolutely no external clamping. This enables access to the entire face and sides of the workpiece without clamping interference,” said Dimac’s Managing Director, Paul Fowler.

“The other key benefit is that because there is no external clamping there is no chance of distorting the workpiece,” Fowler added.

Fowler expects the new XYZ Xpansion Pins to be of interest to a number of different industries including Aerospace, Medical and General Engineering.

Dimac has over 30 years experience in CNC machine tool accessories and are agents for many highly respected brands such as Kitagawa, Cooljet, Reven and Eron. The company also manufactures soft and hard jaws in their own CNC equipped machine shop.

“Like all the products we sell, Mitee-Bite XYZ Xpansion Pins will be supported by the full back up and support of Dimac technical personnel to ensure the right product is specified and operates at optimum performance,” Fowler concluded.
