Introduction To The Drilling Tools Manufacturer's Process


Because the position of the welded steel disc can be changed, the Drilling Tools Manufacturer must determine it before grinding, calculate the correct space path for grinding on the clamping surface, and determine the grinding of the relief angle according to the relevant path, which can e

   The main cutting edge of the drill tool face milling cutter is distributed on the cylindrical or conical surface, the end cutting edge is the secondary cutting edge, and the axis of the milling cutter is perpendicular to the machined surface. According to the tooth material, it can be divided into two categories: high-speed steel and cemented carbide , It is mostly made into a sleeve insert structure, and the tool body material is 40Cr.
   Compared with high-speed steel milling cutters, drill tools have higher milling speed, better surface quality, and can process workpieces with hard skin and hardened layers, so they are widely used. Carbide face milling cutters can be divided into three types: integral type, machine clamp-welded type and indexable type according to the different installation methods of blades and teeth. Drill tools are mainly used on vertical milling machines or horizontal milling machines to process stepped surfaces and planes. They are especially suitable for processing larger planes. The face milling cutter with an entering angle of 90° can mill wider stepped surfaces.
   The drill tool uses a face milling cutter to process the plane. At the same time, there are more teeth participating in the cutting, and the secondary cutting edge has a trimming effect, so that the surface roughness value of the processing is small, so a larger cutting amount can be used, and the productivity is higher. widely. Due to the reduction of drill tools required in the processing process, the entire production process is faster. The tolerances of the geometric dimensions of the parts are only related to the accuracy of the tool, and no longer involve the accuracy of the machining center, and the production process is easier to manage.
   Drill tools are mainly made of cemented carbide materials, which can form the best cutting edge geometry during the grinding process, and the surface quality of the parts is improved. The slot of the drill tool can be rotated or ground directly with a common circular milling cutter or a tapered milling cutter. Both left-handed or right-handed tools have the function of left-handed grinding or right-handed grinding. The core thickness can be programmed via loops or variables. In addition, the user can also use the cutting corner teeth for grinding. This solution is especially suitable for the grinding of high-speed steel bars and hard alloy steel plate welding materials, but not for the grinding of full hard alloy bars.
   Because the position of the welded steel disc can be changed, the Drilling Tools Manufacturer must determine it before grinding, calculate the correct space path for grinding on the clamping surface, and determine the grinding of the relief angle according to the relevant path, which can ensure that all The required profile achieves high precision grinding effect. When processing the back angle of the drill tool, you can use a cup grinding wheel, a drill point grinding wheel, a fillet grinding wheel, and a cylindrical grinding wheel for grinding as needed. It is usually also possible to use the secondary blade to grind the relief angle along the cutting edge. Another method is to use a continuous relief angle path to process by rotating grinding.
