A cutting machine has a blade mounted for reciprocating movement. A workpiece is rotated while the blade is reciprocated, and then the workpiece is rotated through smaller angles to complete the cut. A holder is attached to partially cut slices of the workpiece.

Method and apparatus for cutting workpieces

A radial cut profile is achieved while advancing a workpiece at a substantially constant rate in a direction towards a cutting blade by moving the workpiece vertically relative to the blade in synchronization with the oscillation of the workpiece. The vertical movement is provided by a linkage including two links pivotally connected to each other. The other end of one link is pivotally connected to the feed mechanism. The other end of the other link is fixed relative to the oscillating workpiece.

Method and apparatus to produce a radial cut profile

A cutting blade the core of which is generally tear-drop shaped in cross-section. The sides of the tear-drop shaped core form an included angle of not less than about 5 degrees (and typically not less than about 9 degrees), and abrasive is provided essentially on only the wide bottom surface of the core.

Shaped blades

A wafering machine having a multiplicity of wire cutting blades supported by a bladehead reciprocally moving past a workpiece supported by a holder that rocks about an axis perpendicular to the wires at a frequency less than the reciprocation of the bladehead.

Multi-wafer slicing with a fixed abrasive

A narrow wire blade with abrasive particles plated within a longitudinally-extending, plated cutting portion that extends from only one side of a wire core and has parallel side walls spaced by a controlled width.
