Tungsten steel melt drill, tungsten steel drill bit

Our thin sheet and tube processing industry insight, familiar with working conditions in these industries, we are using a dedicated hot melt drill tungsten steel materials processing, hot melt diamond to ensure ease of use and durability. Hot melt drilling is on the plate or pipe-time processing of the holes and the bush chipless process, completely replaced in the thin-walled workpieces welding (riveting) then nut craft. Hot melt drilling wear-resistant, high temperature materials processing tungsten steel made. When the hot melt drilling and workpiece contact, high-speed rotation (1000 to 3500), and the use of appropriate axial thrust (feed force), so that the occurrence of intense friction between the drill bit and the metal, and instantly reach a temperature of 650 ° ~ 750 ° Celsius in. Metal drill nearby area quickly softened, continue to exert axial pressure, fast on the workpiece, 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. The need for a smooth finished surface or chamfer connection holes, can be planar Fidelity drill to cut the workpiece surface projections. Bush can be used as a bearing support, bifurcated throat welding mouth and other purposes, can also be tapped for threaded connections. Thread the roll forming, processing out of the thread can withstand higher tension and torsion. Reliance chipless drilling process is suitable for processing ordinary steel, stainless steel, aluminum, copper, and other kinds of ductile workpiece materials can also be processed plated parts. Bench can be used for manual or CNC machine tools, the power required 1.5 ~ 3.5kW, spindle speed 1000 ~ 3500r / min. Depending on the workpiece aperture, workpiece material and thickness, the choice of cutting parameters are different.
