Troubleshoot Guide
A bandsaw blade is a cutting tool and ultimately tool life is defined by machine tools and the skill of the operators. Kindly see the effect of five different relations of the blade to enhance its life.
Bimetal is composed of two metals fused together. In the case of the sawblades, the backup steel is composed of high alloy steel and the cutting edge is of M42 (8% cobalt) OR M51 (10% Cobalt), welded using our proprietary Laser welding system. (please insert corrections/ additions)
We have inhouse R&D setup for establishing unique tooth geometry for specific cutting applications. Milling of our saws are basically based on those geometries.
This is the most critical process, involving the chemical bonding of 2 dissimilar metals through laser technology. We have succeeded in developing and operating the laser welding process for welding HSS wire to suitable backing steel.
Quality is in our ethos and we have in place a careful quality control paradigm through the input and output stages, to assure consistency and quality to our customers.
Heat treatment is always the heart of a cutting tool. We have developed special continuous heat treatment process for our saws in very controlled atmosphere furnace. The rate of heating, soaking and rate of quenching is fully controlled by digital programming to have best homogenous and consistent micro structures in the tool.
A new band saw blade has razor sharp tooth tips. In order to withstand the cutting pressures used in band sawing, tooth tips should be honed to form micro-fine radius. Failure to perform this honing will cause microscopic damage to the tip of the teeth, resulting in reduced blade life
