4. Attention for Usage of New Saw Blade
Selected
1. Before loading the new saw blade, keeping the cleaning of the saw
blade wheel and checking if coolant and hydraulic system work
normally
2. Fine and coarse teeth saw blade should be applied according to size
of stocks, please check the above item 3 to choose the suitable saw
blade for your stock so that no any teeth of saw blade broken. For
example, if using small teeth blade (6 teeth blade) to cut big
work-piece (150mm diameter steel rod) will cause too much iron
scurf between teeth, further decrease blade service life.
3. Cutting speed should be lower while cutting material with quite
high hardness
4. The saw blade selecting also should be considered as per the shape
of the stock, teeth-change blade should be used for the profile stock,
keep at least two tooth inside the stock constantly
5. Reasonable to choose coolant liquid for variable stock, oil and
water ratio can be 1:5 for high alloy steel and 1:10 for low alloy
steel and carbon steel
