Various machine car knife blade frequency welding applications, welding technology to provide simple, easy to use.

Ultra-luxury carbide knife- carving instruments permanent plate carving knife.

In the metal processing drilling, milling, boring, stamping process, the less there will be approved front and glitches, and all we want to remove, unwanted parts, the better.

However, in some parts, just want as many processed batch front and burrs. And industry and also involves a lot of scope, including metal furniture, metal doors, metal lighting, air conditioning ducts, metal connecting frame construction, metal shelves, seat belt bearing holder, pressure vessels watershed hole, metal pipe connections, medical equipment, automotive accessories, fitness equipment, switching system piping ......

Under normal circumstances, some industries listed above pipe connections are direct drilling, welding or tapping. But encountered some special requirements, it is not strong enough direct drilling soldering, welding sealing is not ideal; or direct drilling and tapping, only the thickness of the wall of the thread tooth is too short, not strong enough, such as a metal stool , shaking shaking thread on the bad.

The above problem, a change of the processing tool can be solved. Direct drilling waste will be drilled, but the diamond drill replaced melt, melt scrap that part will be able to drill up under the direction of extrusion. Extrusion scrap that we pursue the approved front and glitches, it could have been only a 1mm wall thickness 2mm becomes even 3mm. Tapping this point in time, that tooth length is two to three times the original.

Feng batch melt drill and burr advantages arise after processing, determines it is widely used in metal processing.

Hot melt drilling is on a metal sheet or pipe holes and machined bushings chipless processing technology, completely replace the welding on thin-walled workpieces (riveting) pick nut craft. Melt drill with wear, made of high-temperature alloy materials. When the melt drill and workpiece contact, high speed (1000 to 3500), and appropriate axial thrust (feed force), so that the occurrence of severe friction between the drill bit and metal drill melt temperatures up to 900 degrees, processing instant point reached 650 ° ~ 750 ° C temperature. Metal area around the drill bit to soften quickly and continue to apply an axial pressure on the workpiece rapidly, the lower surface of the extruded sheet is about three times the initial thickness of the bosses and the liner. The whole process takes only 2-6 seconds. As a nut applications, and the number and intensity of the thread teeth were significantly improved after the bushing may tapping. Is the best alternative to weld nuts. Bush can serve as soldering, welding or brazing fastening connection port.

Squeeze through wire tapping tapping it on the thin material of high-precision, high-strength thread, effective solution to the thin sheet, tube, pipe parts tapping problems, greatly improving the connection strength; without using point welding cylinder, nuts, washers, simplifying manufacturing processes, and high precision, thereby reducing product scrap, saving production costs.

The processing method using the conventional rivet, low intensity; or weld nut and bushing, cumbersome and complex and costly process. The use of hot melt drilling only two steps, you can produce high-precision, high strength threaded bushing, effort and material cost savings will not only save time, but no debris polluting, easy 6S management.

Use hot melt drilling is an efficient new technology, new technology. Hot melt drilling can be installed in the robot, gas drilling, manual bench, pistol drill. Without special equipment, ordinary drilling, CNC milling machine or CNC machining center can be used. No hot melt extrusion molding drill cuttings because chipless machining, drilling precision, long service life, particularly suitable for industrial automation.

Fusing drill very versatile: mainly used in automobiles, motorcycles, construction, decoration, machine tools, machinery, electronics, appliances, furniture, waterways and shipbuilding and automation equipment.

Due to the unique principle melt melt drilling performance, both on the high-speed steel, alloy steel bearing even after quenching the workpiece for drilling high hardness, but also stainless steel, mild steel, copper alloys and other components for processing.

Use: suitable for a variety of metal materials processing a wall thickness of 0.5-12.5mm.
