Grinding wheel, known as the "tooth" of industry, is an indispensable basic tool in manufacturing industry. It micro-cuts the workpiece through countless high-hardness abrasive particles, and its application is wide, which runs through almost all links from rough blank treatment to nano-scale ultra-precision machining.
What can a grinding wheel do?
1. Precision grinding: the pursuit of the ultimate size and shape. This is the most classic and high-tech application field of grinding wheel, aiming at obtaining extremely high dimensional accuracy, geometric accuracy and surface smoothness. Cylindrical grinding: specialized in processing the outer surface of rotating parts such as shafts, rollers and rods. For example, the crankshaft of an automobile engine and the spindle of a machine tool all need cylindrical grinding to achieve micron-level accuracy and mirror-like smoothness. Internal grinding: used for finishing holes in workpieces. The inner ring of the bearing and the valve hole of the hydraulic valve all need internal grinding to ensure the roundness, cylindricity and size consistency of the hole. Surface grinding: used to create a high-precision plane. The base of the mold, precision measuring tools (such as block gauges) and the end face of the seal need to be ground by plane to ensure their flatness and parallelism. Centerless grinding: an efficient batch processing method, especially suitable for small-sized cylindrical parts, such as bearing rollers, pencil lead, piston pins, etc., which can be ground at high speed without locating the central hole.
2. Cutting separation: efficient and neat "industrial scissors" The thin-slice cutting grinding wheel is used to quickly separate various materials. This is one of the most intuitive and common uses of grinding wheel. Application scenario: cutting steel bars and stones on the construction site; Blanking section steel and steel pipes in a metal processing workshop; Used for demolition in emergency rescue; The samples were cut and sampled in the laboratory.
3. Polishing and dressing: "Beauty" and "Body" for the workpiece. This field focuses more on the surface condition and edge treatment of the workpiece than on the extreme dimensional accuracy. Cleaning and deburring: remove sand holes, scale, flash and riser on the surface of castings and forgings to prepare for subsequent processing. Welding seam treatment: smooth the convex welding seam to make it smoothly transition with the parent material, which is not only beautiful but also can eliminate stress concentration. Chamfering and fillet: grinding bevel or arc on the sharp edge of the workpiece to prevent scratching, facilitate assembly and improve the fatigue strength of the parts.
where does the grinding wheel play a role?
The footprints of grinding wheels are all over all heavy industries and high-tech industries. In the automobile manufacturing industry, from the crankshaft, camshaft and valve of the engine to the gear of the gearbox and then to the brake disc, it is inseparable from precision grinding. At the same time, in the whole vehicle production line, huge cutting grinding wheels and grinding grinding wheels are used for finishing and correcting the body after welding. In the aerospace field, grinding wheels are faced with "hard bones" such as titanium alloys and superalloys. Here, the superhard material (CBN/ diamond) grinding wheel is used to process key components such as heat-resistant turbine blades and landing gear, and the requirements for performance, safety and reliability have reached the extreme. In the tool and mold manufacturing industry, grinding wheel is the "machine tool" for manufacturing tools. Whether it is cemented carbide drill or high-speed steel milling cutter, it is necessary to use (usually diamond) grinding wheel to grind sharp cutting edges. The mold cavity also depends on high-precision grinding and polishing to ensure the quality of the final product.
