Stellite Tip Wide Bandsaws

Thode Knife & Saw Ltd utilise state of the art machinery to provide you with the highest quality, stellite tipped wide bandsaws. The operational time of a wood bandsaw can be considerably increased by tipping the teeth with wear resistant alloys such as stellite. This is especially evident on hardwood species, but is today also extensively used in the processing of softer woods like pine. Thode stellite tip bandsaws with No12 grade stellite. This grade has proved to be the best solution. It consists of 52% Cobalt, 30% Chromium, 9% Wolfram and 1.8% carbon with a hardness of 47-51 HRC.

EM2 Side Grinder	SAA Stellite Tipper

Stellite tipping at Thode is carried out by state of the art, Iseli SAA fully automatic stellite tipping machine. This provides for more accurate tip placement and significantly reduces the risk of downtime due to tip failure. It is vital that the grinding of the stellite is carried out correctly to achieve considerably longer operational times and better surface finishes. at Thode side grinding accuracy is assured as all side grinding of stellite saws is carried out on the fully automatic Iseli  EM2 CNC side grinder

Resistance Welded Tip	Finished Tip

The Iseli EM2 features resistance welding of the stellite tips to the saw. This method ensures that no cracks or holes are produced during the welding process. The base material is critical to the performance of the stellite saw and Thode use Sandvik Multishift Steel as a base material. This steel has a higher tensile strength which permits higher blade tension (approx 20%) and consequently gives better stability in sawing. Multishift steel also has higher relaxation resistance,  which means the blade will hold its tension longer and a higher fatigue strength allows for longer operational times. Close thickness tolerances and better steel flatness ensure advantages in both the manufacture and maintenance  of the stellite tipped bandsaw.
