Performance and Features

The series CNC deep hole drill machine is the dedicated drilling machine with high efficiency, high precision and high automation.
The tool is rotating when feeding. It adopts the mode of external chip removal. Through one-off drilling process. It can finish several procedures including drilling, expanding and reaming, which is generally conducted by different machines in the conventional process.
This machine achieves the excellent machining accuracy and surface roughness.
It adopts CNC system and has automatic cycle function.
To improve the productivity, the machine can be equipped with single or 2 or 4 spindles configuration. So it is specially suitable for mass production. It can process through hole, blind hole and step hole.
