Drilling unit head

SF-110VDLT-Z/Z

Max.drilling spindle travel:150mm

Spindle outer diameter:φ110mm

Max. drilling diameter:φ50mm

Spindle taper: BT40 .

1,Spindle feeding controlled by built-in oil hydraulic pressure.

2, Unit head is with functions of fast forward, slowing processing, fast backward

3,Feeding depth is adjustable.

4, Feeding depth is adjustable, mechanical limit switch, repeated positioning accuracy 0.03mm.

5,Movement change signal in unit head are all controlled by limit switch.

Tapping unit head

SF-110VDLT-Z/G

Tapping spindle max. Travel:120mm

Spindle outer diameter: φ110m

max. Tapping capability: M40

the processing thread lead depends on the exact work piece

Spindle taper: BT40.

1,Driven by lead screw, automatic feed to tapping, ensuring standard thread pitch and is easy to change.

2,Tapping depth are within ±0.1mm

3,The change of the movement of the unit head are all controlled by limit switch.

The table is precisely indexed to 3 parts

inner table :φ340mm

cycling table:φ550mm

hydraulic pressure:35kg/cm

indexing precision(accumulation value): 4″

Repeated precision:±1″

time for cycling and locking one position is about:1.3s.

1,Adopts rotary indexed table, do the drilling and tapping operations synchronously,dramatically reduce the processing time.

2,The indexing and positioning of the rotary table uses triple plates gear, there is not lift movement when indexing,plus with rigid sealing structure, thus not leakage of chip or cutting liquid to the inside of the rotary table even in circumstances of large cutting liquid.

3,The indexing and positioning operations are all driven by hydraulic pressure.
