Q: How to solve the problem of obvious corrugation on the inner surface during deep hole processing?

A: When using, first ensure that the radial runout of the drill bit is within the required range, and secondly ensure that there is sufficient internal cooling pressure to ensure 

good chip discharge.

Q: What is the maximum diameter of deep hole drilling?

A: Currently, OSG can produce 60 diameters.

Q: What is the tolerance of the guide hole?

A: The blade diameter tolerance of ADO-40D·50D is e8, and the guide drill diameter tolerance is recommended to be made as 0~+0.05.

Q: For stainless steel drilling, how to solve the problem of tool sticking during processing?

A: Use a stainless steel special drill that focuses on sharpness, such as the ADO-SUS series, and ensure sufficient internal cooling pressure, such as 3Mpa.

Q: What is the optimal parameter for the general feed rate of deep hole drilling?

A: We recommend 2% of the drill diameter as the starting parameter, and then adjust it according to the chip shape.

Q: How to ensure the straightness of deep hole processing?

A: This question is difficult to answer directly. First of all, you need a drill with excellent performance. Secondly, you need to cooperate with many factors to achieve the 

desired goal, such as pilot drilling, processing conditions...
