Abstract

1434884 Special processes; trepanning DE MAN ISOLATIE BV 28 Feb 1974 [9 March 1973] 9099/74 Headings B3C and B3T In a method of making hollow trough-like workpieces such as curved pipe insulation pieces from hard synthetic plastics material, a sheet or disc 1 of the material is supported on a worktable (not shown) and a rotary cutting device is fed perpendicularly towards the surface of the sheet, the device having a rotary spindle 2 which carries one or more radial arms 3 to which cutter blades 4, 5 and 9, 10 are attached, the blades being positioned at appropriate radial distances from the axis of the spindle about which they rotate and which corresponds to radius of curvature of the finished workpiece. In the embodiment described a pair of such cutting devices are shown one with cutting blades which form the internal configuration and one with blades 9, 10 which form the external configuration. The respective spindles 2 and 7 act as guide members during the infeed of the cutting blades, the spindle 2 making a guide bore through the sheet or disc and the spindle 7 entering the bore formed by the spindle 2 after the internal machining operation has been completed. Although Fig. 1 shows the sheet or disc being machined alternately from both sides it is preferable for the construction of the machine to perform the operation from one side and invert the sheet on the work-table after each internal machining operation.
