When steel structure CNC deep hole drilling machine high-strength material workpieces, the cutting speed V should be appropriately reduced.
ALGSD40/2 High precision deep hole drilling machine worktable and bed of the ALGSD25/2 horizontal double-spindle CNC deep hole drilling machine are separated, so that the clamped workpiece will not be affected by the bed vibration. The worktable is cast with stable precision.

According to the material of the workpiece, the cutting amount is reasonably selected to control the degree of chip curling, and C-shaped chips which are favorable for chip removal are obtained. When machining high-strength material workpieces, the cutting speed V should be appropriately reduced. The amount of feed has a great influence on the formation of chips, and a small feed can be used under the premise of ensuring chip breaking.
