small hole drilling edm DS703A, X and Y axis DRO, High accuracy, Micro Hole 0.3mm, TM ISO9001:2008 - details see: https://www.machineto.com/small-hole-drilling-edm-ds703a-10124900

Main Technical Data Type DS703A Worktable Size 400×300mm Worktable Travel 250×200mm Servo Travel 330mm Spindle Travel 200mm Electrode Diameter Φ0.3 - Φ3mm Max. Working Current 22A Power Input 380V/50Hz 3.5kW Machine Weight 600kg Overall Dimension 1070×710×1970mm

This machine is mainly used for stainless steel, hardened steel, carbide, copper, aluminum and the deep hole processing of other conductive materials.

Such as moly wire of EDM cutting workpiece, fiber spinneret, spinning holes of spinning plate,

group holes of filter board and sieve plate, cooloing holes of motor blades and cylinder body, oil and gas channel hole of hydraulic and pneumatic valve.

Worktables’s X,Y axis is equipped with digital device.

Use pure water or tap water as the working fluid.

It can directly penetration process from inclined plane and curved plane.

The maximum depth ratio could be 200:1 or more.

This machine can also be used to remove aiguille and screw tap of workpiece and avoid damaging the original hole or threads.

The mechanical part is mainly composed of the coordinate worktable, spindle head, swivel head, column and machine tool body.

The electric cabinet is fixed in the machine tool body, including the pulse power supply, the principal axis servo system and the machine tool electric-appliances.

The operating fluid system includes the high-pressure pump and the operating fluid container, which are located at the side of machine tool body (seen as the above figure).
