Abstract
A clamp for clamping parts on cutting machine tools includes a housing containing a rotary disc having a clamp arm and a toothed sector projecting from the disc which meshes with a tangential screw which rotates the disc to apply a clamping force to the clamp arm. The disc is journalled in a pair of cheek members that are fixed within the housing, and cooperate with the disc to present cylindrical radial bearing surfaces and planar annular lateral bearing surfaces. The annular lateral bearing surfaces of the disc are contiguous with the cylindrical outer surface of the disc on which a pair of scraper blades run, and the annular lateral bearing surfaces of the cheeks are substantially flush with the inner wall of the housing so as to protect the housing against ingress of foreign matter. The diameter of the outer cylindrical surface portion of the disc is less than the inner diameter of the toothed sector to enable a fixing screw to be accessible by a tool from the top of the housing.
