New, high value universal grinder from Kellenberger

A new universal cylindrical grinding machine from Swiss specialist Kellenberger & Co. majors on providing excellent value at the entry level while offering reliability, precision and high productivity via its state-of-the-art intuitive programming function.

Available in the UK from Rugby based Jones & Shipman Hardinge, the Kellenberger 10 (K10) combines proven technology using many Kellenberger components and sub-assemblies from the established K100 machine coupled with the latest programming technology.  This uses the Kellenberger Blue teach/programming software that enables semi-skilled operators to use the machine, thereby optimizing use of the work team.

The standard machine can accommodate workpieces up to 1000 x 400mm in size with a top table weight capacity of 100kg.  The table profile is also a proven Kellenberger design with the full length wheel dressing interface located on its rear to reduce re-tooling work and extend the wheel dressing possibilities.

The machine features generous X and Z axis strokes (X=365 mm / Z=1,150 mm), collision-free operation and dressing ratios. The low-maintenance, high-precision linear guide on the X axis and the V flat sliding guides on the Z axis are equipped with optical absolute linear position measuring systems. The B axis is designed as an automatic indexing axis (1° Hirth gearing) with high positioning accuracy and a +30°/-210° swivel range. 

The K10 also offers the ability for users to greatly expand or customise its capability by adding a range of optional equipment such as a second external grinding wheel, larger grinding wheels, a tailstock, gap control and balance sensors and measurement control via probing. 

It features an extremely stable sub-frame to minimise external influences and vibration which can adversely affect surface finish, all-round component quality and sustained process accuracy.  

The Kellenberger BLUE solution software is accessed through a Fanuc 0i-TFP CNC control with a 19” touch screen.  Programming, re-tooling and a remote diagnostic feature extend the opportunities for using the machine on a wide variety of applications across the machine shop.  The operator does not need DIN or ISO skills.

For optimum productivity and flexibility, the universal grinding head can optionally be equipped with two 500/400mm ø O.D. grinding wheels. Powerful high-frequency, grease-lubricated I.D. grinding spindles with direct drive are available in two speed ranges (6,000 – 40,000 rpm and 10,000 – 60,000 rpm.

“This machine brings all of the proven design, assembly and reliability features associated with the Kellenberger brand to a much wider market via its highly competitive pricing structure,” claims Mike Duignan, managing director of Jones & Shipman Hardinge.
