12.2 - DEFECTS OF THE BLADE / CAUSES / SOLUTIONS
In case of broken teeth, broken blades or short blade life, please check the defects; look for them in the following list
and read the solution of the cutting problem .
1. PREMATURE AND EXCESSIVE TEETH WEAR AND TEAR
- insufficient pressure - the teeth slide on the material
- cutting speed to high - the teeth slide on the material
- cooling jet too short;
- improper cooling emulsion;
- toothing too big or overloaded;
- running-in of the blade not appropriate;
- the blade has been mounted contrarily: turn the blade.
2. THE TEETH BREAK / THE BLADE BREAKS
- the teeth are too big for the section that must be cut; they are overloaded, at least 3 teeth should work at the
same time
- the teeth are too thin for the section that must be cut; exhaust throats are full of chips
- the material is not perfectly blocked;
- cutting pressure is too high, possible locking in the material
- the blade is not well fixed to the spindle
- the cut has beeb started against one angle
- high pressure: the teeth are overloaded and lock in the workpiece
3. BENT CUTS
- pressure is too high
- the speed is too high
- the blade must be sharpened
22 - MACHINE DEMOLITION
This paragraph may give some informations about the macrooperations of machine disassembly for its scrapping.
Special procedures are not required but it is necessary to take only some cares to avoid damages in the last phase of
the machine life.
