Common problems and improvement strategy
1. product deformation: The fixture design is not reasonable, or product temperature is so hot to deform.
Improvement strategy: The fixture is designed in 3D or positioned slightly to pull, add water or coolant when brushing. raise the sand belt height of wire drawing machine. Or extend drawing time.
2. Deep line: Abrasive belt and nylon wheel surface wear or entrainment. Insufficient lubrication.
Improvement strategy: Replace the abrasive belt, Clean sand belt and nylon wheel with saw blade and copper brush, Wax or grease, Elevating the sand belt height and lowering the speed of drawing machine.
3. Product drawing Angle: There is no limit on the perimeter and hole position of the fixture.
Improvement strategy: Product perimeter and hole position limit. Heat treated or cemented carbide using D2, Limit replaceable
