摘要： A cutting apparatus such as a metal-cutting circular saw apparatus has an axially displaceable shaft for mounting a saw blade. The shaft is hydrostatically supported both in the radial and in the axial direction. To provide for the axial displaceability of the shaft, the shaft is axially hydrostatically supported at one end by means of an annular piston. The piston bears with a radial end portion thereof against a shoulder in the bearing housing, the shoulder projecting into the cylinder in which the piston is displaceable. The piston is of such a cross-sectional shape and elasticity that in an operative position it is elastically pivoted or tilted, thereby reducing the clearance between the piston and the cylinder, so the piston can carry bearing forces in a radial direction, and also eliminating the need for piston sealing means.

摘要： A cutting apparatus has a cutting tool mounted on an e.g. pivotal support member, under the plane of cut, the cutting tool cutting upwardly through a workpiece to be cut by movement of the support member. The support member is carried by a pivot mounting on a vertical main support plate, the pivot mounting being so arranged that the plane of the cutting tool is substantially aligned with the middle of the pivot mounting. The tool feed forces are applied to the support member close to the notional plane of pivotal movement of the support member, which plane extends through the cutting tool, while the main support plate is adapted to carry clamping means on its top.

摘要： An apparatus and method of clamping tube-like members on a clamping support, for cutting off portions of the tube-like members are provided. Clamping forces are applied to the tubes alternately in horizontal and vertical directions in such a way that the clamping forces generated are higher than clamping forces which are applied only in a horizontal direction, without however causing permanent deformation of the tube-like members. The apparatus comprises a horizontal clamping mechanism and a vertically displaceable clamping member. A measuring device is associated with the horizontal clamping mechanism and the vertically displaceable clamping member, for measuring the geometrical deformation of the tube-like members which occurs during a clamping operation. The measuring device produces a signal to stop the clamping operation before the degree of deformation of the tube-like members reaches an inadmissible value.
