Drill Series Enables Accurate High-Speed Machining
IMTS 2018: Kyocera Precision Tools’ DRV Magic Drill series of indexable drills is designed for holemaking in the machine tool business.
Kyocera Precision Tools’ DRV Magic Drill series of indexable drills is designed for holemaking in the automotive, aerospace and medical device industries. The series combines a CVD-coated insert on the outside cutting edge and a PVD-coated insert on the inside cutting edge. This enables high-speed machining and drilling precision.
The insert chipbreakers improve chip evacuation, and the holder’s thick center core provides rigidity. The series can reach depths from 2×D to 6×D. The series includes diameters ranging from 0.625" to 1.000" and from 14 to 32 mm. Four chipbreaker designs cover a range of machining applications.
The inserts are designed with four usable cutting edges to reduce machining costs. The outside insert cutting edge has a U-shaped design that provides smooth chip evacuation and compact chips that reduce chip clogging. The inside cutting edge has a spoon-shaped design to reduce cutting forces for smoother chip evacuation even at 6×D drilling depth. The holder body’s flutes provide a large web thickness. A high-rigidity holder body with low cutting resistance provides stable indexable drilling.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
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.
Consider these alternatives when conventional drilling can't do the job.
