Tungaloy Adds Changeable-Head Tool to Drilling Grade Series
Tungaloy is expanding its AH9130 drill head grade series to include the DMP drill head line from the DrillMeister changeable-head drill series.
Tungaloy is expanding its AH9130 drill head grade series to include the DMP drill head line from the DrillMeister changeable-head drill series. A self-locking interface connects the drill head and tool body to simplify tool changes. Operators can replace the tool without removing the drill body from the adapter or re-measuring tool offset values,
This AH9130-grade expansion encompasses the DMP line of general-purpose drilling, succeeding the DMC drill head for precision drilling. Developed specifically for drilling applications, AH9130 is a nano-multilayer PVD coating consisting of three layers. This coating configuration is designed to provide longer, more predictable tool life by adding wear, fracture and oxidation resistance as well as resistance to buildup and delamination.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
