ado-susドリルで不水溶性切削油（内部給油）の使用は可能か | オーエスジー

Is it possible to use insoluble cutting oil (internal lubrication) in ADO-SUS drills?

Compared to water-soluble cutting oil, the cooling effect and oil discharge amount are poor, and the following problems are likely to occur.

 

・ chipping of cutting edges due to welding

・ Breakage due to chip jamming caused by an increase in chip size

 

In order to solve the problem, we recommend the following processing method.

 

・Reduce the cutting speed of the cutting condition table by 30%.

・Set the feed amount per rotation of the drill to 1.5%~2% of the drill diameter.

・ Insert a step of about 20% of the drill diameter and process. However, at this time, do not pull the drill back, but stop feeding for about 0.1 seconds by duel.
