Abstract
Abstract A machine for simultaneously electrochemical processing a plurality of workpieces in which a workpiece receiver is mounted on spring loaded rails between a clamping unit and a base for horizontal movement between loading and operating positions. A working electrode extends through a bore in the clamping unit to create a working gap with a workpiece which is electrically connected via a spring loaded contact member to a source of eroding current. The clamping unit can be moved up and down to make and break electrical contact and to clamp and release the workpieces. Electrolyte is supplied to and removed from the working gap.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
A machine for simultaneously electrochemically machining a plurality of workpieces comprising; a workpiece receiver for mounting a plurality of workpieces; a plurality of working electrodes; guide rail means mounted on said support base, for removably mounting said receiver, to permit horizontal movement thereof between a loading and a processing position, said guide rail means accurately positioning said workpieces with respect to said electrodes for machining; a clamping element for holding said workpieces between said support base and said clamping element; means for vertically moving said clamping element to clamp and release, respectively, said receiver; means for defining a working gap between each electrode and workpiece; means for supplying electrolyte to and removing electrolyte from said gaps; and means for connecting a source of eroding current to said electrodes and workpieces.
Claim 2
Dependent Claim
130 words
A machine for simultaneously electrochemically machining a plurality of workpieces comprising; a workpiece receiver for mounting a plurality of workpieces; a plurality of working electrodes; guide rail means mounted on said support base, for removably mounting said receiver, to permit horizontal movement thereof between a loading and a processing position, said guide rail means accurately positioning said workpieces with respect to said electrodes for machining; a clamping element for holding said workpieces between said support base and said clamping element; means for vertically moving said clamping element to clamp and release, respectively, said receiver; means for defining a working gap between each electrode and workpiece; means for supplying electrolyte to and removing electrolyte from said gaps; and means for connecting a source of eroding current to said electrodes and workpieces.
Claim 3
Dependent Claim
158 words
A machine for simultaneously electrochemically processing a plurality of workpieces comprising: a workpiece receiver for mounting a plurality of workpieces; a support base; first and second guide rails, mounted on said support base for engaging said receiver, to permit horizontal movement thereof; a clamping element for holding said workpieces between said support base and said clamping element; means for vertically moving said clamping element to clamp and release, respectively, said receiver; a contact member extending for limited vertical movement in a bore in said support base to electrically contact said workpiece; first spring means engaging and urging said rails upward to break the contact between said contact member and said workpiece when said clamping element is lifted; a plurality of working electrodes; means for defining a working gap between each electrode and workpiece; means for supplying electrolyte to and removing electrolyte from said gap; and means for connecting a source of eroding current to said electrodes and workpieces.
Claim 4
Dependent Claim
158 words
A machine for simultaneously electrochemically processing a plurality of workpieces comprising: a workpiece receiver for mounting a plurality of workpieces; a support base; first and second guide rails, mounted on said support base for engaging said receiver, to permit horizontal movement thereof; a clamping element for holding said workpieces between said support base and said clamping element; means for vertically moving said clamping element to clamp and release, respectively, said receiver; a contact member extending for limited vertical movement in a bore in said support base to electrically contact said workpiece; first spring means engaging and urging said rails upward to break the contact between said contact member and said workpiece when said clamping element is lifted; a plurality of working electrodes; means for defining a working gap between each electrode and workpiece; means for supplying electrolyte to and removing electrolyte from said gap; and means for connecting a source of eroding current to said electrodes and workpieces.
Claim 5
Dependent Claim
