APos 800 / APos 1200
High speed small hole EDM drilling machine type APos 800 CNC with PC control system.
For the machine of these series a completely new layout was designed in co-operation with the company Abacus GmbH. The machine body is made of mineral concrete.
The new machine body is an especially developed, modular construction. The usability of the machine series is improved again by rearranging of the layout. Control system and generator are now placed in two separate electrical cabinets. Altogether a compact construction with small required space has been developed. The new housing, made of stainless steel meets highest safety standards. It can optionally be used as basin for machining in water or oil.
The main features and advantages of this new conception are:
- better thermal stability
- higher mechanical stiffness
- big work piece weight
- fully cased working area
- robot connection possible
- compact construction
- continuous path control for up to 5 axes simultaneous machining
- EDM milling
- Network compatible
- adaptive measuring sensor system
- integrated tank and filter unit (600 liter body housing)
- included camera-system
- minimum removal rate adjustable
- measuring used electrode & applicable again
