Solutions aplenty

Designed to complement 5-axis machining technology, Schunk Intec has developed a range of workholding solutions.

Unnecessarily long set-up operations can hinder productivity significantly but with Schunk's quick change pallet system the Schunk Unilock, the operator sets-up in parallel to the processing time, while the machine processes another workpiece, increasing output, reducing costs and eliminating potential operator error.

Within a few seconds during workpiece change, the workpiece pallets with the Schunk Unilock interface are fixed, positioned, and clamped precisely in the machine. According to Schunk, application examples show that using the system can reduce set-up costs by up to 90%.

With the Schunk Unilock, mounting and positioning are done via a short taper which ensures a repeat accuracy of < 0.005mm and thus offers ideal pre-conditions for precision machining on a 5-axis machine with holding forces of up to 75,000N.

The workpiece clamping devices in 5-axis machining should be compact and sturdy, ensure a safe hold and allow plenty of room for the workpiece and unimpeded access to the working spindles. The compact centric clamping device Kontec KSK from Schunk meets all the criteria. It has a large clamping range and can be used as a rough part clamping device and precision toolholder with a centring accuracy of 0.02mm. Its special geometry is ideally suited to 5-axis machining.

The Kontec KSK is a completely encapsulated centric clamping device. Even in harsh environments, it is fully functional and reliable and the metal housing saves personnel intensive and expensive cleaning times. With the modular changing jaw system, a wide variety of workpiece sizes and geometries can be safely clamped in the Kontec KSK.

Ideal for single part and small batch production the Kontec KSC accommodates conventional clamping, small clamping depths, moulded parts, plates or workpieces with saw cuts. The Kontec KSC features a forward facing construction that makes it possible to design high supporting jaws. In this way, all sides of the workpiece can be ideally reached without danger, even with standard tools at a clamping force that can be increased to as much as 35kN.

A powerful all rounder for the 5-axis machining of round workpieces is the stationary manual Rota-S plus chuck from Schunk. Through use of reversing top jaws, the user can rapidly switch from OD to ID clamping and thus cover a wide clamping range with the same top jaws. The quick change jaw system shortens the time for a complete jaw change to around one minute.

Functional components hardened and ground on all sides ensure the Rota-S plus has a high repeat accuracy of 0.02mm, so that turned, soft jaw sets can be used over and over again. Like the two Kontec clamping modules, the 3-jaw chuck Rota-S plus can be combined with the quick change Unilock pallet system.
