Thame Stamps Its Mark on Workholding with MTD

Thame Stamps Its Mark on Workholding with MTD

Added to MTDCNC by Thame Workholding on 27 February 2017

For anybody that may be unfamiliar with the Lang range of workholding products, Gareth Barnett, Sales Manager at Thame Workholding talks us through the simple process of the Lang system from Thame.

The operation begins with a stamping process. The customer stamps the billet with an accurate form that determines a depth stop and also a form that locates with the teeth of the vice. By stamping the part prior to machining, the Lang system exerts less stress on the workpiece material. Rather than clamping the workpiece, the tapered face of the Lang device locates the pre-stamped parts and prevents movement in all directions. This stamping process provides the end user with a repeat accuracy of 10 microns, so if a part is removed and then re-inserted for re-machining, precision is assured.

The modular range has a choice of three different jaw widths, which are 46, 77 and 125mm wide. The modular devices work on a Lang zero-point clamping system that improves consistency, quality and reduces set-ups for the end users. The four locating studs can be rapidly tightened with a wrench to achieve up to 6 tonnes of pull-down force.

For the clamping of irregular parts, Thame offers a soft-jaw system that supports the machining of all component types. This flexible zero-point system can be used on 3, 4 and 5-axis machining centres as well as on horizontal machine tools. Thame can also supply multi-part plates or tombstones for the machining of multiple components. Furthermore, the introduction of a tombstone system will enable the end-user to orientate the component through 90 degrees for greater accessibility to difficult to access faces.
