Insertable Form Drill System Reduces Setup Times
IMTS 2018: Schwanog’s PWP and PWP-D insertable form drill system reduces setup times with an insert holder that stays in the machine during insert change-over.
Schwanog’s PWP and PWP-D insertable form drill system reduce setup times with an insert holder that stays in the machine during insert change-over. This design keeps the center height unchanged. The insertable carbide tool is ground individually per customer specifications, it can hold a minimum tolerance of ±0.02 mm and the repeatability is 0.02 mm. The systems are available in several carbide grades.
The insertable form drill systems have a maximum bore diameter of 28 mm and a maximum depth of 16 mm. The company also offers solid carbide drills to complement for larger bore sizes and deeper holes. The solid carbide drills are ground individually per customer specifications, and accommodate a minimum tolerance of ±0.02 mm.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
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.
