New Neidlein Face Drivers offer even more productivity gains

When turning shafts, the common way is to hold one end in a chuck and the other supported by a live centre.

However, the issue with this procedure is that a part of the end of the bar remains un-machined. This means that the shaft needs to be removed and turned around to maintain concentricity whilst re-gripping the turned diameter – a time consuming and annoying practice, usually requiring overhead lifting equipment.

By using a face driver, either in a chuck, or directly mounted to the spindle nose, the shaft is supported between centres and the shaft is driven by means of a series of special drive pins.

This means the entire surface of the work piece can be machined in one set-up.

“Using a face driver eliminates second operations, maintains concentricity along the full length of the shaft and allows for faster loading and unloading times,” said Dimac Managing Director, Paul Fowler.

“Face drivers optimise production flow, reduce manufacturing costs and of course eliminate wastage. The Neidlein unit is also very reliable as it has no internal hydraulics,” Mr Fowler went on to say.

Founded more than 60 years ago, the German based Neidlein-Spannzeuge GmbH has been operating successfully on the international market throughout that time.

Their specialised and highly motivated team manufacture a range of face drivers for clamping between centres for turning, cylindrical grinding, milling and hard turning operation.

When required, the company is also able to develop customised solutions in close co-operation with their customers.

The latest range of Neidlein face drivers just released now offer even more benefits.

Thanks to an innovative floating quick change drive head, it can now handle a wider range of shaft diameters without the need to refit the face driver body.

“This new quick change drive head dramatically reduces set up time if you’re processing a range of shaft sizes, leading to a big increase in productivity,” said Mr Fowler.

“Like all Neidlein products, the face drivers are manufactured in Germany, so high quality and durability is a given,” Mr Fowler added.

Dimac Tooling is Australia and New Zealand’s leading supplier of accessories and workholding solutions for CNC milling and CNC turning machine tools. The company also manufactures soft and hard jaws in their own CNC equipped machine shop in Dandenong, Victoria.

“Like all the products we sell, the Neidlein range has the full back up and support of Dimac technical personnel to ensure the product is installed correctly and operates at optimum performance,” Mr Fowler concluded.
