quality Tungsten Carbide Buttons & Tungsten Carbide Inserts manufacturer

    1.What's it?     1.Hot melt drilling technology is in sheet metal or pipe last time out of the hole and bushing chipless machining technology, completely replace the welding, riveting nut on the thin-walled workpiece process.Hot melt drill, adopt the wear-resisting, high temperature resistant cemented carbide materials.     2.Hot melt drilling technology is in sheet metal or pipe last time out of the hole and bushing chipless machining technology, completely replace the welding, riveting nut on the thin-walled workpiece process.Hot melt drill adopts wear-resisting, high temperature resistant cemented carbide materials.When the cutting tool and workpiece contact, high speed (1000 ~ 3500), and appropriate axial thrust (feed), the friction between the drill and metal, instantly at the temperature of 650 ° ~ 750 ° centigrade.The metal in the vicinity of bit softening quickly, to continue the axial pressure, squeeze about fast on the workpiece, the surface is three times the thickness of the board of the initial convex sets and bushing.The entire process takes only 2 to 6 seconds.For smooth connection surface or chamfer hole processing, can use planar prudential bit, with resection in workpiece surface convex platform.Liner can be used as a bearing pedestal, bifurcate throat welding mouth purposes, can also be tapping, for threaded connections.Thread for rolling into shape, processing of thread to withstand higher tension and torsion.Prudential chipless drilling technology is suitable for processing of ordinary steel, stainless steel, aluminum, copper, and other various has the ductility of the workpiece material, also can plating of workpieces.Can be used for manual bench drill or CNC numerical control machine tool, the required power 1.5 ~ 3.5 kW, the spindle speed of 1000 ~ 3500 r/min.According to the processing aperture, material and thickness of the different work piece, the selection of cutting parameters is also different.Advantages: high efficiency, economy, save material, and processing the workpiece more beautiful 2.Advantages:   1. No chip, thread can sustain tension and torsion   2. A chipless machining, without having to remove waste.   3. On the convex molding precision is high.   4. Suitable for a variety of tapping machine.   5. High speed, long life and production increase.   6. Suitable for a variety of material can melt bore 3.Apply to the following situations:   1.To lengthen thread   2.Welding company, multi-layer heat exchanger   3.Bearing brackets   4.Stainless steel construction or metal furniture screw connection 4.Application industry:  1.The car industry  2.Bicycle industry  3.Stainless steel furniture  4.Aeronautics and astronautics  5.The central heating  6.The lighting industry  7.Construction machinery and metal  8.Electroplating coating industry 5.Hot drill guide to the choose and buy   1.According to the need to drill through the workpiece thickness, there are two kinds of hot drilling length specifications:   2.Short drill: applicable to penetrate the workpiece thickness in 0.8 mm - 3 mm   3.Drill: used to penetrate the workpiece thickness is greater than 3 mm to 12 mm   4.According to the requirements of the workpiece after hot drilling through the surface, hot drilling, there are two specifications:   5.Standard hot drilling, hot drilling through the artifacts of the lining sleeve for the stretch forming on the surface to form a convex ring at the same time  6.Flat mouth hot drilling, hot drilling through the artifacts of the lining sleeve for the stretch forming cut the workpiece surface convex ring out at the same time, the surface smooth  7.Stainless steel drill, screw tooth aperture M8 or more, hot drilling diameter of 0.1 mm and larger lower drill speed 10-20% of non-ferrous metals, raise drilling speed by 50%
