Tensilgrind for Hard Metals

April 23, 2009

Tensilgrind is a precision contour grinding machine designed for the preparation of physical test specimens from high hardness metal foil and sheet. Tensilgrind employs the basic principle of Tensilkut, wherein a precision master template is manually guided across the table surface with the removal of metal accomplished in a series of light grinding passes.

Tensilgrind is designed to be located in the metallurgical laboratory, so it is available for grinding test specimens as they are needed, rather than waiting for them to be finished by a machine shop in days or weeks. Laboratory personnel without previous machining experience can readily grind specimens from hard metals and super alloys, resulting in a greatly reduced per specimen cost.

The formed grinding wheel with a ½” hub shaped to a 5/16” width obtains minimum wheel contact with the specimen, while providing maximum wheel rigidity. A radius dressed on the periphery of the wheel by a built in diamond wheel dresser reduces the contact of the wheel with the specimen to a small point for minimum generation of heat.

Tensilgrind templates are interchangeable with the Tensilkut machines, enabling the user of both machines to have just one set of templates. Accordingly, the Tensilgrind is offered with three different control head heights, although the maximum capacity of any machine is the same. The limitation on the thickness of the material which can be prepared on the Tensilgrind is caused by the radius of the grinding wheel, which would imprint upon too thick a sample.
