Schunk set to grip the crowds at Southern Manufacturing 2016

21 December 2015

At the Southern Manufacturing 2016 exhibition on stand S110, Schunk will be promoting a host of new products launched throughout 2015, plus established product lines.

Many manufacturers have now recognized they can improve surface finishes and tool service lives by utilising the innovative Tribos system; and at Southern Manufacturing from the 9th to 11th of February 2016, the latest interfaces will be on show. These new interfaces deliver a higher level of standardisation for the precision tool holding systems for micro machining and are now available with the Tribo-RM and Tribos-Mini ranges.

The Tribos-Mini that has been designed for high-speed micro applications can now be integrated with a high-speed HSK-E 20 spindle interface. The clamping technology experts at Schunk believes this newly standardised interface is superior to many short taper interfaces due to its accuracy at high speeds. In addition, it needs much less space compared with the HSK-E 25 interface. Schunk has designed the robust Tribos-RM with an extended L1 dimension of 78mm especially for high-efficiency 5-axes machining. 

In order to allow precision machining of hard-to-reach areas, the mount can also be combined with the standardized Tribos-SVL tool extension with adaptations for HSK-A 32, HSK-A 40, HSK-E 32 and HSK-E 40 interfaces. In addition, Schunk has expanded its range in such a way that many of the previous special solutions will now be included in the standard catalogue. For example, Tribos-Mini will be standardized with ø 1, 1.5, 2, 3, 4, 6mm and 1/8 inch.

Tribos-RM with ø 3, 4, 6, 8, 10, 12mm and 1/8 inch. In addition to the HSK-A 25, -A 32, -A 40, -E 25, -E 32, -E 40 interfaces that are already available, both mounts will also be available for HSK-E 20, HSK-F 32 as well as for BT 30 and SK 30. These units from Schunk are part of the world’s most comprehensive programs for high-precision tool clamping and can now be manually actuated via the SVP Mini and SVP-RM devices.

Additionally, Schunk will be keen to promote to the aerospace and composite machining fraternity the Tendo-E Compact hydraulic expansion toolholder. Capable of reducing set-up times by up to 60 percent whilst generating up to 2,000Nm of torque, the Tendo-E Compact delivers micron precision for a host of machining applications. With this precision toolholder, even demanding applications with tight tolerances on the form, position and surface finish can be rapidly and reliably machined.

Another product that will be of interest to the high-tech visitors and exhibitors alike at the show, will be the innovative SPM Plus 138 fixture membrane. Manufactured from aluminium, the SPM Plus provides the clamping of a multitude of geometries from all sides with its innovative pull-down effect. 

Firstly, a 0.5mm high tuning ring is inserted between the quick-change pallet module and the fixture membrane, and then the exact workpiece geometry is milled according to the blank on the fixture’s clamping surface. Once prepared and the tuning ring removed, the workpieces can be inserted within seconds and the complete circumference be clamped by locking the Vero-S module. This in turn deforms the fixture membrane to provide the clamping.

The SPM & Vero-S module will be complimented by the Schunk PRONTO quick jaw change system that has a change-over time of 5 seconds per jaw. The new Schunk Pronto quick jaw change system offers remarkably fast set-up times for all standard lathe chucks with fine serrations of 1/16in x 90° and 1.5mm x 60°. The quick-change retrofit set from the competence leader for clamping technology and gripping systems consists of supporting and changing jaws. 

The new innovation is suitable for OD clamping of pre-machined and finished parts. Utilising a selection of interchangeable inserts, the clamping range can be extended up to 16mm without having to re-set the supporting jaw - an increase of 300% in comparison to conventional lathe chucks. 

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 has a clever, forward-looking 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. 

Since the whole process is carried out within the elastic range of aluminium, the clamping operation can be repeated several thousand times. In contrast to conventional clamping blocks, the clamping force of this clamping method is carried out at the circumference of the whole workpiece contour and not just along an axis. Due to the clamping depth of only a few millimetres, the workpiece is fully accessible from five sides. 

From a maintenance perspective, the Linomax special grease from Schunk is recommended for the lubrication of power chucks. The light-coloured adhesive grease with solid lubricants has been specially developed for sliding surfaces exposed to high pressure loads and water in the form of metal machining emulsions. It is especially resistant to washout, prevents seizure and provides anti-corrosion and excellent anti-wear protection.
