Appropriate tool
Is not easy to define the appropriate tool for a certain processing tasks. Many cases depending on the batch size of the workpiece and the actual processing of complexityOne approach is based on the process to be completed to perfect adjustment tool. Doing so the need to consider all the variables used as efficiently as possible to ensure the effective processing time for each step (the actual processing time). This method is disadvantageous in that requires a wide range of different tool. This will increase the downtime (machine / tool to adjust the time), to effectively reduce the available time. Briefly, this method provides a shorter effective time, but very idealized.abrasive wheel Another method is to use a general-purpose tool. This approach will reduce the downtime (less), thereby increasing the effective time available for the adjustment and maintenance of the tool. However, the effective time of use is not very efficient, because the tool is in the process does not achieve the best adjustment.abrasive manufacture The best method would be the mixing of the two alternatives. A practical application is feasible only through "analog": compare alternatives, determine the time and decide which method is the best overall solution.
The next step is to consider the tool selection cutting materials
The next step is to consider the tool selection cutting materials. The most common cutting materials in the metal processing industry can be divided into two categories: non-ferrous and ferrous materials. Non-ferrous materials including aluminum and aluminum alloy, copper and copper alloys, magnesium alloys, nickel and nickel alloys, titanium and titanium alloys. Ordinary ferrous materials including carbon steel, alloy steel, stainless steel, tool steel and iron casting materials such as cast iron. Non-ferrous metal is relatively soft, easy to cut, but other than nickel and titanium. Ferrous metals are usually hard and difficult to cut. Tool selection, tool material is the most important factor to consider. The majority of these tools are three basic materials: high-speed steel, carbide and carbide cog. Almost all of these basic tool material can be used for cutting of various materials. The only difference in performance. The hardness of high speed steel cutting tools is very high, but poor wear resistance. The carbide wear resistance is very good, but easy to break. Carbide cutting material suitable for use in high speed and feed rate, but the price is more expensive. Carbide cog tool is very suitable for mass production applications because each cog has a plurality of cutting edges. A cutting edge wear, you can be divided into degrees to another cutting edge have been used in all cutting edge, simply replace the cog, rather than the entire tool.grinding disc Tip: If you are using a high-speed steel drills, you must first use the center drill. Then drilling. This ensures that the correct location of the borehole. If you are using a carbide drill first drill center, carbide drill with their own pair nose. If you use a carbide drill drilling has been executed the center hole drilling process will damage the drill. Outer cutting edge in contact with the conical wall before the drill began cutting. This external impact cutting edge and lead drill fragmentation. Carbide drill must first begin cutting from the tip, and then use the outer cutting edge.abrasive tools
Blade maintenance
⒈ blade if not used immediately, it should be flat or inner hole suspension, not stack other items or foot flat on the saw blade, and pay attention to moisture-proof, grinding wheel,anti-rust.⒉ when the saw blade is no longer sharp cutting surface roughness, must be promptly re-grinding. Grinding can not change the original point of view, and the destruction of dynamic balance.⒊ saw blade diameter correction, positioning hole processing must be carried out by the factory. If the processing is bad, it will affect the effect of product use, and may be dangerous, cutting wheel,reaming principle it can exceed the original aperture 20mm, so as not to affect the balance of the stress.
The alloy saw the role
Alloy saw: also called carbide saw blade), is open in a the processed molding and heat treatment after circular thin steel sheet (substrate) on a number of teeth, and the tooth portions inlaid carbide tips a circular saw blade in the hole, through the center of the substrate, mounted on the rotating spindle, the chuck clamping, rotating cutting work.Carbide saw blades: by using the occasion can be divided into hand tools - power tools - professional use with circular saw blades, machinery and equipment (table saw, grinding wheel,sliding table saws, precision saws, woodworking machinery, etc.) type of circular saw blades, high precision professional precision than power tools. Its price is high.Aluminum alloy blade: also known as cut aluminum blade), mainly used for cutting aluminum extrusions,cutting wheel, aluminum, aluminum rod, aluminum radiators and other non-ferrous materials, non-ferrous materials are difficult to machine materials, thus cutting performance special accuracy requirements, require the targeted design, manufacturing.Woodworking saw blades: is alloy saw blade, carbide saw blades) used in woodworking and furniture manufacturing industry, dedicated to cutting all kinds of soft and hard solid wood, MDF, fiberboard, particleboard, bamboo such blade commonly known.
