Abstract
A traveling-wire electrical machining system with improved accuracy results by providing, in addition to the usual electrode guide arms straddling the workpiece and by which the electrode is sharply deflected in its path from the supply coil to the backup coil, a second pair of arms guiding the stretch of the electrode immediately forming the machining region. According to the invention, the second pair of arms, also straddling the workpiece, engages the electrode between each deflection location and the workpiece. The second pair of arms is mounted on the column independently of the first pair of arms so that the second arms are not affected by deflection of the first arms.
Claims5
A traveling-wire electrical discharge machine for electroerosively machining a workpiece located in a machining region with a condinuous elongate electrode, said machine comprising:
- a single column mounted on a machine base;
- supply reel means mounted on said column for feeding said continuous elongate electrode;
- takeup reel means mounted on said column for collecting said continuous elongate electrode;
- a pair of first arms individually mounted to said column and supporting at their respective end portions a pair of first guide sections for spanning said continuous elongate electrode therebetween across said machining region and for guiding said continuous electrode from said supply reel means toward said machining region and for guiding said spanned electrode toward said takeup reel, respectively;
- means for advancing said continuous electrode and transporting it through said machining region;
- a pair of second arms mounted individually to said column and supported independently of said first arms by said single column between said first arms and supporting at their respective end portions a pair of second wire guide sections spacedly positioned between said first wire guide sections across said machining region for guiding said spanned electrode precisely in line with a cutting section across a machining gap in said machining region.
