CNC Gundrilling Machine

Main machines of Gun drilling series:

ZSK Three-dimensional deep hole drilling machines

ZSK Single-dimensional multi-spindlle deep hole drilling machines

Gundrilling is a deep hole drilling process that uses a long, thin cutting tool to produce holes at high depth-to-diameter ratios.

Our gun drilling machines, adopts gun drill chips remove methods, though one time continue drilling, can get the processing quality of drilling, expanding and reaming.

Diameter accuracy IT7-IT11

Surface roughness: Ra0.4-Ra6.3

Diameter central linear less than 0.5-1/1000mm

Drilling diameter range:3mm -40mm
