A.There is a window on the machine bed for pump pressure, which is easy and convenient to look and adapt water pressure .
B.Servo control system is adopted and improved, which make drilling re-track speed 2 times quicker than DB703
C.There is slider water tank, which saves space and is more environmental.
D.There is oil-tank for lubrication, which is more convenient to operate and fluid to lubricate.
E.Able to drill various conductive metals, such as stainless steel, chilly steel, solid carbide, copper, aluminum .
F. Able to drill holes range from diameter 0.2- 3mm with max depth-diameter ration 300:1.
G.It is more stable while drilling hole of 0.2mm
H. Drilling speed 30-60mm/min
I.Able to drill directly into bevel or curve surface.
J. Three axis digital display
K.Drilling depth positioning function for Z axis
L.Control system can drill group hole and positioning automatically.
Main performance indexes and technical requirements
Basic configuration:
（1）Three axes have digital displays; it is consistent with operation
（2）Z axis uses linear guide rail (driven by the step motor with 5 phases 10 beats), it is driven by DC motor
（3）The rotary head is of straight gear transmission, its volume is small
（4）The super large scales integrate circuits make the impulse power supply reliable
（5）The multiple power supply of high and low voltage and high-power VMOS field -effect transistor
（6）The double Z is moved by motor
（7）The operate-control box is adjustable, it is fully considered to convenience of operator
（8）It contains the operation and control mode of DB703
（9）The specialty plunger pump, thread gap filter
（10）The marble working table
（11）The stainless fixtures
（12）The accessories and consumable parts
（13）The processing polarity can be changed
（14）The processing stability is adjustable
