Ø The operation console cantilever-mounted, and its position and orientation can be adjusted at will, making the operation more convenient and quick.

Ø The X,Y,Z three-axis moving parts of the machine tool adopt precision linear guideway and ball screw.

Ø X, Y and Z axes adopt AC Servo system and DC servo motor, which has high speed and accurate positioning.

Ø The workbench moves fast, which shortens the moving time between holes and improves the processing efficiency.

Ø The structural parts are manufactured from high quality cast iron.

Ø The rotary head is of straight gear transmission.

Ø The specialty plunger pump, thread gap filter

Ø The marble working table, semi-submerged work tank.

Ø Equipped with stainless steel workpiece installation fixture

Ø Equipped with centralized lubrication system.

Controller characteristics

Ø Can drill deep hole with diameters 0.3mm ~ 3mm (the depth-diameter ratio is 300: Ø The speed of drilling hole is 10mm-100mm depth per minute (it is different for different material)

Ø Can drill small holes on the various conductive materials, even semiconductor material, especially stainless steel, chilled steel, copper, aluminium and hard alloy etc.

Ø Can drill on oblique and curved surface directly.

Ø Can easily erode the drill and screw tap etc which is broken in the workpiece and not destroy the screw thread of the holes.

Ø The working water can be normal water or saponification fluid and no pollution is brought.

Ø Convenient system operation, easy to use.

Ø Hand remote control box operation.
