SOLUTIONS FOR STELLITE TIPPING AND SWAGING FOR BAND, GANG AND CIRCULAR SAW BLADES

Stellite tipping

Stelliting refers to the process of applying stellite® to the saw teeth and thereby hardening them. This increases the abrasion resistance of the saw cutting edges, which in turn leads to longer machine service life, increased cutting accuracy and reduced set-up times.

Stelliting is especially advantageous when particularly abrasive and hard woods are to be sawn. Stellite® no. 12 (containing 59% Cobalt, 29% chrome, 9% tungsten and 1.8% carbon) has proved to be extremely successful for machining wood. It is wear-resistant while not being too brittle, and can be ground without problems. In some cases, stellite® no. 1 is used: This is an extremely hard alloy, which is primarily used for sawing wood with a high proportion of silicate.

Swaging

Swaging saw teeth is another possibility, along with setting, for ensuring that the saw can cut freely during machining. For the swaging process, a swaging bolt is placed in front of the saw tooth. The saw tooth is held in place with an anvil. By turning the eccentric swaging bolt, the sawing material is pushed towards the tooth tip. When the swaging process has ended, the swaging bolt turns back to its starting position.
