The self-tapping threaded Turning parts are made of a standard 35mm diameter round rod as the base material, overall cylindrical and an outer threaded section at one end with a standard tooth profile, used for screwing into pre drilled holes or directly into soft materials; The other end is an inner threaded section, with multiple radial grooves designed in the inner hole to form an elastic expansion structure. 304 stainless steel has excellent corrosion resistance, mechanical resistance and stability, effectively prevents the sliding and displacement of the thread and improves the durability and reliability of the connecting parts. It is a highly adaptable Stainless Steel Self fitting Threaded Insert Parts.
Step 1: Select a 304 stainless steel round rod, perform high-precision cutting and end face leveling according to the specifications and dimensions of the self tapping screw sleeve to ensure consistency in the outer diameter and length of the raw material, laying the foundation for subsequent precision machining.
Step 2: Use a high-precision CNC lathe for one-time clamping and forming, sequentially completing processes such as inner hole boring, outer circle precision turning, inner and outer thread rolling turning, and end face chamfering. Based on the mature precision cnc turning machining capabilities, it controls the coaxiality, the roundness and precision of the slot profile strictly with precise and controllable dimensional tolerances, to ensure a uniform space between the screw couplings and a smooth use of the slot.
Step 3: Cut and mill the head of the self-tapping threaded insert into equal slots, accurately control the slot width, depth, and cutting angle, and ensure that the cutting slots are neat and free of burrs.
Step 4: Perform manual and machine dual deburring and precision chamfering treatment on the thread tip, port edge, slotted incision, and inner and outer hole walls to remove residual sharp edges and iron filings from CNC turning and CNC milling, improve surface smoothness, and avoid scratching the substrate and affecting installation accuracy during assembly.
Step 5: After ultrasonic degreasing and cleaning, perform a complete inspection of dimensions, specifications and appearance. Only qualified stainless steel self-tapping threaded insert parts can be packaged and shipped.
