Product Description

High Efficiency Self Drilling Screw Machines

The process for making self drilling screws:

Step 1: Cold heading machine

Step 2: Self drilling screw forming machine

Step 3: Thread rolling machine

1. Automatic Cold heading machine
This equipment adopts cold heading way to make the wire rod upsetting by double-click the whole mould form. Finished Feeding, straightening, cutting material, forming, discharging by one machine.

2. Self drilling screw forming machine
This equipment adopts cam surface design, does not affect the processing of forming the molding cycle time, can extend the time of stamping, and reduce the air travel time, to achieve good characteristics of the movement to ensure that mold life.

HRC60 ° grinding precision, rolling friction wear less, perfect zero backlash curve.
High-speed no noise, no energy waste.
High precision, OPR, absolute synchronization.
Simple structure Screw drive, very few failures.

3. Fully automatic thread rolling machine

This equipment adopts two thread profile thread rolling plate staggered 1/2 screw distance design, dead plate is fixed, movable plate equal to dead plate do straight line motion back and forth, when the work piece feed between two plates, movable plate move forward twist work piece, make its surface plastic deformation into thread.

Thread rolling machine is portable, flexible, high efficiency and has some irreplaceable advantages compared with similar equipment, avoid the limit of lathe, drill or hand tapping, save time, labor, not easy to rotten teeth, screw tap not easy to break off.
