Hainbuch quick-change system minimises set-ups

Becker GmbH in Wuppertal, Germany now relies on CentroteX quick change-over systems from Hainbuch to simplify set-up processes and guarantee repeatability of ≤0.003 mm.  

Optimal planning of Becker’s manufacturing processes is achieved by production technology manager Dirk Schmidt, using the SMED method [single minute exchange of die]. This makes it possible to set up a machine or a production line within a production cycle so that it can be reused with only minimal delay.

“The most important aspects of the method are accuracy, low-distortion clamping and set-up minimisation,” says Schmidt in describing the clamping device requirements. “Hainbuch is one of the few companies that helps the customer to develop solutions. I usually have an idea of what I need and discuss it with Hainbuch. We work together to optimise processes and achieve the best possible result.”

In a planned production line, Becker will machine several different vacuum pump housings. The first clamping set-up will use the Hainbuch CentroteX S quick change-over system with different mandrels for ID clamping to ensure maximum centring accuracy with minimum deformation. The workpiece is removed from the first clamping set-up and equipped with four zero-position clamping bolts, which will be used in all subsequent clamping set ups and potentially also in assembly. Downstream machining steps will then take place on a machining centre with a rotary table. A Hainbuch quick change-over system mounted on the table generates an additional axis.

In this set-up, Becker uses a pallet from another manufacturer on a Hainbuch clamping adapter. In this way, the company benefits from minimal set-up times and high repeatability of the Hainbuch quick change-over system if the factory’s set ups require clamping devices that are not included in the Hainbuch product range.
