#CMT# #/CMT# The device has a base body comprising a base plate (2) and a cover plate (3) screwed with each other. A region of surface of the cover plate is formed as a flat seal (9). Another flat seal (10) is provided as a separate component at a lower side of a slide valve (8), where the lower side is turned towards a surface of the cover plate. The slide value is guided in a radial guide (7). A circulating O-ring seal (11) is mounted above the seal (10) at a side, which is turned away from the corresponding seal (9), under pre-stress such that the seal (10) is continually pressed against the seal (9). #CMT#USE : #/CMT# Three-jaw clamping device for clamping a workpiece e.g. pipe or component made of glass-fiber reinforced material or other brittle material, in a machine tool. #CMT#ADVANTAGE : #/CMT# The slide valve is guided in the radial guide, and the circulating O-ring seal is mounted above the flat seal at the side, which is turned away from the other flat seal, under pre-stress such that the former flat seal is continually pressed against the latter flat seal, thus providing a reliable sealing of the guide, ensuring that smaller particles, fine abrasive dust and diamond dust are reliably kept away from the guide of the jaw in a simple and clean manner, and ensuring free movement of the clamping jaw after long operating time. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a three-jaw clamping device with a slide valve in a moving direction. 2 : Base plate 3 : Cover plate 7 : Radial guide 8 : Slide valve 9, 10 : Flat seals 11 : O-ring seal. |
