摘要:
A single station shaper sander that uses a quick change retractable shaper and a quick change retractable profile sander is described. The shaper generates a profile in a substrate, and then the sander sands the profile in the substrate without intermediate removal of the substrate. Both the shaper and sander are retractable, moving away from the substrate when retracted, and are moved into contact with the substrate when engaged. Either an operator or automatic controls may be used to engage and retract the shaper or sander, so as to minimize operator access to dangerous moving surfaces on either. Further, each sander or shaper may have removable tools that are temporarily affixed to a spindle, affording tool changes of 15 seconds or less.

A shaping machine for making profiles on tools includes a mechanism for the mechanical adjustment of a grinding wheel at the same time as a positioning of the tool, to obtain substantially identical and accurate tool pieces using a dummy template. Movement of the grinding wheel and tool workpiece allows for the making of profiles of different shapes and sizes, having both concave and convex parts. The machine can also be used for grinding already moulded profiles to sharpen tools for example.

In a grinding or milling machine for machining spiral cylindrical cutters with a hemispherical head in one operation, comprising a horizontal displaceable carriage, or orientable work tool holder, a headstock including a cutter-supporting spindle adapted to slide on the carriage along a direction parallel to the axis of the spindle, and means for helically driving the headstock spindle, the headstock is secured on a support mounted on the carriage for rotation and inclination respectively about (a) a vertical axis intersecting the axis of the spindle and (b) a horizontal axis perpendicular to the plane of said intersecting axis.
