Different  Machining processes  need use different cutting tools. Such as: holes need use driller, Screw need tapper, , Milling cutting  need use milling tools etc. MACHINING CUTTING TOOLS TYPES: AS PER MATERIAL QUALITY TO CLASSIFY CUTTING TOOLS TYPES White steel cutter : easy to wear and tear, used for roughening copper and small steel. Tungsten steel cutter:  used for angle clearing (especially steel) and smooth knife. Alloy cutting tool : similar to tungsten steel knife. Purple cutter:  used in high speed cutting, not easy to wear. machining cutting tool AS PER CUTTER HEADS TO CLASSIFY CUTTING TOOLS TYPES: Flat-bottomed cutting tool : for flat and straight side, clearing plane angle. Ball head cutting tool : It is used for light knife and light knife in all kinds of curved surface. Bull nose cutting tool:  (unilateral, bilateral and five sides): used for roughening of steel (R0.8, R0.3, R0.5, R0.4). Coarse cutting tool : used for roughening, pay attention to the

CNC machining  works for  Mold ,  Fixture ,  Prototype  or other  metal work pieces .  Roughing machining  and  Final Machining are the necessarily processes. What is Roughing Machining? Roughing machining:  Cut-out more materials from original blocks, bars by cutting tool. Machine tool  ( CNC lathe,  CNC milling  machine, CNC router  etc) adopts maximum load. Normally, the largest  cutting tool should be selected, the largest feeding amount and fastest feeding speed be chosen. When use same cutting tool, the feed is inversely proportional to the cutter feeding amount. Normally, the load of machine tools is not a problem. The principle of cutter selection is mainly based on whether the two-dimensional angle and three-dimensional arc of the product are too small. After choosing a good cutting tool, the length of the tool can be determined. The principle is that the length of the tool is larger than the machining depth. For large  machining workpieces , the interference of the

In the  machining process  of  CNC Turning  Lathe, CNC router,  CNC milling  machine,  machining work piece  clamping is an important step. A suitable clamping method affect the cutting tools choose, cutting parameters setting and save machining time to save cost. machining work piece clamping method MACHINING WORK PIECE CLAMPING METHOD AND RULES: 1.MACHINING WORK PIECES CLAMPING DIRECTION: All  machining part  clamp direction is: long horizontally and short vertically. CNC turning part be clamped 2.GEAR CLAMPING: The clamping height should not be less than 10 mm. The clamping height and the machining height must be specified when  processing the workpiece . The machining height should be about 5 mm higher than the plane of the vise in order to ensure its firmness without harming the vise. This kind of clamping belongs to general clamping. The clamping height is also related to the size of the work-piece. The larger the work-piece, the higher the clamping height. 3.SPL

Heat treatment  always used in steel iron metal parts to improve the hardness, to get quality  machined parts  which met mechanical design requirement. Heat treatments functions : improving the mechanical properties of materials eliminating residual stress improving the machinability of metals. metal machining part be heat treated According to different purposes, heat treatment process can be divided into two categories:  preparatory heat treatment  and  final heat treatment . 1.PREPARATORY HEAT TREATMENT The purpose of preparing heat treatment is to improve processing performance, eliminate internal stress and prepare good metallographic structure for final heat treatment. Its heat treatment process includes annealing, normalizing, aging, tempering and so on. 1) ANNEALING AND NORMALIZING Annealing and normalizing are used for hot-worked blanks. Carbon steel and alloy steel with carbon content more than 0.5% are usually annealed to reduce their hardness and easy to
