SELFEEDER DUO SD4 : Servo Feed Drilling and Tapping Unit

SF_SD4

SELFEEDER DUO SD4

SD4 type is a model with increased spindle torque and thrust copared to the SELFEEDER DUO (SD3), which is capable of both drilling and tappig in one unit.

Increased productivity by high-speed, high-feed machining, and speed reducer plus simultaneous machining multiple holes.

 

Max. drilling size  … φ18(Steel)/φ12(Aluminum)
Max. tapping size … M24(Steel)/ M22(Aluminum)

 

Specification Chart / Drilling and tapping dual-purpose type

Notes:

  • Select a model based on workpiece specifications, machinability, tool specifications and cutting speed.
    The maximum drilling capacity shown above is the value at a drilling depth of twice the drill diameter.
    Tapping capacities are conditional on the depth of tapping being limited to 1.5 times of the tap diameter.

  • If the maximum drilling capacity exceeds the chucking capacity, special tools (with steps) shall be prepared by the customer.

  • If your drilling and tapping needs exceed the figures in the capacity chart, please contact the nearest sales office.

  • ER collet is adopted for spindle nose. Use collet ER-GB when chucking a tap.

  • Misalignment between a pre-hole and a tap can cause early tap damage, select a tap holder.

  • A servo motor for feed is with a holding brake, “B” is added to the end of SELFEEDER DUO model number.

  • AL : Aluminum(ADC12) , FC : Cast iron(FC200) , ST : Steel(S45C)
