Self Drilling Screw Thread Rolling Machine

Details

Principle of operation
Parallel Plate Design: The screw thread rolling machine adopts two parallel plates, with the length of the stationary plate as the standard, which should be more than 20 times of the diameter of the object to be processed, but not more than 35 times, to ensure the accuracy and stability of the finished product.

Requirements for the number of turns: The design of the equipment requires that the number of turns of the tooth plate for wood screws should be not less than 6 turns, and that for machine screws should be not less than 4 turns. If the number of turns is not enough, the workpiece will be forced to be extruded and produce oval or other abnormal deformation, affecting the material structure and quality of the finished product.

Summary of advantages
Waste-free production: Direct pressing process, no cutting waste, saving material costs.
High efficiency: High-speed production improves productivity and is suitable for mass production.
High finish: Finished products have high surface finish and exquisite appearance.
Uniform precision: Ensure that the precision of each finished product is consistent, improve product quality.
