3, Polished bevel for minimum friction.

Problem	Reason	Measure
Uneven wear, frequent blade replacement	1. The surface of roller or dryer is uneven 2. The doctor holder is damaged or dirty 3. Sediment	1. Use a softer blade 2. Clean, repair or replace the doctor holder 3. Use abrasive blade
Excessive wear on middle or edge of blade	1. The blade is not installed on the top of the roller 2. The old blade sinks (or leaves) the roller or dryer	1. Refit or add gasket at the back of blade if necessary 2. Replace the old and sunken blade
Excessive wear at one end of blade	The displacement of blade is not parallel to the axial direction of roller or dryer	Add gasket, if necessary, move bearing and bracket to adjust scraper parallel to axial direction
The blade is worn evenly, but the end face is rough	1. There is deposit on the surface of roller or dryer 2. The pressure of blade is too high 3. The material of blade is too hard	1. Use abrasive blade when necessary 2. Reduce the pressure 3. Use a slightly soft blade
Excessive wear in sheet area	The sheet leaves sediment on the roller or dryer	1. Use abrasive blade when necessary 2. Trim the edge of blade frequently 3. Use blade with slotted end to prevent excessive pressure on both ends of roller or dryer
Excessive wear out of sheet area	The sheet lubricates the roller or dryer	Use blade with slotted end
Local depression	The blade is damaged, electrostatic (discharge/ electrolysis /heating)	Insulate the blade from the holder or use a non-metallic blade
The blade produces burr	1.The material of the blade is too soft 2. The pressure is too high 3. The angle of the blade is too small	1. Use a slightly hard scraper 2. Reduce the pressure 3. Adjust the bearing or bracket to increase the angle, and use the instrument to check and correct the angle
