Standard Configuration:
(1) Taiwan HIWIN linear guideway and precision ball screw

(2) Electrical plunger pump

(3) Patent integrated rotation head


Machine's characteristics:
(1) Can drill deep hole with diameters 0.2mm ~ 3mm (the depth-diameter ratio is 300:1)
(2) The speed of drill hole is 30mm~60mm depth per minute (it is different for different material)
(3) Can drill wire-cut starting hole, filter hole, jet hole, gas hole, group holes and hole of super depth etc.
(4) Can drill small holes on the various conductive materials, even semiconductor material, 
especially  stainless steel, chilled steel, copper, aluminums and hard alloy etc
(5) Can drill on oblique and curved surface directly
(6) Can easily erode the drill and screw tap etc which is broken in the workpiece and not 
destroy the  screw thread of the holes
(7) The working water can be normal water or saponification fluid and no pollution is brought
(8) The operation is easy and convenient
(9) X, Y two axes digital readout
