Drilling and tapping machines can use U-drills. U-drills are wear-resistant, heat-resistant, highly precise, and highly stable, ensuring accurate and consistent hole diameters during drilling. Furthermore, U-drills utilize indexable inserts, eliminating the need for resharpening when worn, allowing for simple replacement of inserts. This significantly improves processing efficiency and reduces costs.
When using U-drills on drilling and tapping machines, consider the following:
Machine Tool Rigidity: U-drills require high machine tool rigidity, so ensure the drilling and tapping machine has sufficient rigidity to support stable operation.
Speed and Feed Rate: Select the appropriate speed and feed rate based on the material being processed and the specifications of the U-drill to improve processing efficiency and ensure quality.
Insert Selection: Use a tough center insert and sharper peripheral inserts to accommodate varying machining requirements.
Cooling and Lubrication: Ensure adequate cooling and lubrication during machining to reduce tool wear and extend tool life.
