Defects on the material or material too
hard
Material surfaces can be oxidized or covered with
impurities making these areas harder than the
blade itself. Materials may have hardened areas
or inclusions inside the section due to production
materials such as castings and welding wastes,
etc. Avoid cutting these materials. In a situation
where a cut has to be made use extreme care,
cleaning and removing hard impurities as quickly
as possible.
Insufficient lubricating refrigerant or wrong
emulsion
Check level of liquid in the tank. Increase the
flow of lubricant. Check to ensure the blade
guide outlet hole and the liquid outlet pipe are not
blocked. Check the lubricant viscosity.
Blade breakage/damage
Faulty welding of blade
Switch to a superior quality blade.
Cut advancing too quickly
Decrease cutting advance, exerting less cutting
pressure. Adjust the braking device.
