Deep-hole drilling
to the center of the workpiece:
a little twist changes the result!

After receiving this inquiry, Muratec’s after-sales support team reviewed the situation and proposed a solution using simultaneous rotation of the spindle and the live tool.
Through this method, the workpiece is clamped in the chuck and rotated as usual, while the drill rotates in the opposite direction during machining.

By rotating both the workpiece and the drill, the required cutting speed can be achieved while keeping the drill’s individual rotation speed lower.
This helps suppress vibration caused by centrifugal force and stabilizes the machining process.

By adopting this machining method, the customer achieved stable coaxial accuracy.
In addition, this approach can be effective in addressing issues such as unexpected drill breakage, improving product accuracy, and enhancing overall process reliability.
