Reliable domestic retention knobs utilizing superior U.S. steel con enhanced set-up rigidity, which improves tool life and cycle times Contract machine shops and OEMs rely on CNC milling machines to produce very precise components in industries such as medical, aerospace, automotive, motorcycle, and gun manufacturing. However, consistently achieving precisely machined components requires a quality retention knob, particularly in high-speed, high-volume applications.

Aerospace manufacturing requires precision and very tight tolerances from CNC milling machines, even when machining exotic alloys and hard metals or aggressively removing more stock to stay competitively productive. However, consistently achieving precisely machined components requires a quality retention knob, particularly in high-speed, high-volume applications.

In milling machines, retention knobs used with tapered toolholders can engage drawbars that secure the toolholder firmly in the spindle. The tapered toolholder has threads designed to accept the retention knob, but improper seating of V-flange toolholders lowers productivity and causes runout and vibration that reduce machining precision, tool life, and spindle life.

For contract machine shops and OEMs that rely on CNC milling machines, T.J. Davies retention knobs utilize superior U.S. steel to enhance setup rigidity, while improving tool life and cycle times. Poorly designed retention knobs from overseas are often made of low-quality steel that may be prone to breaking during machining. Newer CNC milling machines exert significantly more drawbar pressure on retention knobs than in the past.
