HSS-CO Hot Melt Drill Special Use Forming Tap M3 M4 M5 M6 M8 M10 M12

The hot-melt drill generates heat through high-speed rotation and axial pressure friction, plasticizes the material, and at the same time punches and forms a bushing about 3 times the thickness of the raw material. Precision, high-strength threads.
It effectively solves the problem of tapping thin plate, square tube and round tube parts and improves the connection strength; it does not need to use simplified spot welding, nuts and washers, which simplifies the processing sequence, and has high precision, thereby reducing the scrap rate of products and saving money. Cost of production.
The use of hot-melt drilling is a new process of energy saving and environmental protection. New technology.
Can be installed on machining centers, CNC machine tools, milling machines, bench drills, hand drills, drilling machines and other equipment
It is suitable for processing various metal materials with a diameter of 1.8-32MM and a wall thickness of 0.5-12.5MM. After processing, a circular boss will be formed on the surface of the workpiece.
The surface of the workpiece is flat after the flat-type hot drilling process, which is formed by flattening the annular boss by the cutting edge in front of the shank.
Because the thickness of the barrel after the hot melt drilling process is relatively thin, conventional cutting taps cannot be used when tapping threads, but cold extrusion taps are used, and the extruded threads are very strong. , High hardness is not easy to wear and enhance torque force.
The hot melt drill will generate high temperature during processing, which will transfer heat to the spindle of the drill rig and cause damage to the fixture.
The machine-clamping tool holder with special heat dissipation function is used together, which can not only improve the accuracy and protect the equipment, but also effectively dissipate heat.The clamping part of the cooling wing handle can be selected according to the connection method of the machine tool, and the chuck can be selected according to the size of the hot drill.
Due to the unique performance of the hot-melt principle of the hot-melt drill, it can not only drill high-speed steel, bearing alloy steel and high-hardness workpieces after quenching, but also process parts such as stainless steel, low-carbon steel, and copper alloys.
Widely used in automobile and motorcycle manufacturing, furniture, construction, decoration, machine tool machinery, aerospace, electronics, electrical appliances, waterways, shelves, shipbuilding and automation equipment, etc.
