The grinding performance of cubic boron nitride abrasive tools is very good, not only can be used to process difficult-to-grind materials, improve productivity, but also help to strictly control the shape and dimensional accuracy of the workpiece, but also effectively improve the grinding quality of the workpiece and significantly improve The surface integrity of the workpiece after grinding improves the fatigue strength of the parts, extends the service life, and increases the reliability. In addition, the cubic boron nitride abrasive production process is better than ordinary abrasive production in terms of energy consumption and environmental pollution. Therefore, expanding the production and application of cubic boron nitride abrasive tools is mechanical application and an inevitable trend in the development of the machinery industry.
1. Sharpening and rough grinding of tungsten, tungsten and molybdenum and other high speed steels, especially vanadium alloy steel, cobalt alloy steel, special high speed steel cutters.
2. Precision grinding and final grinding of precision parts made of heat-resistant steel, stainless steel and high-hardness alloy structural steel. When these parts are used with ordinary abrasive tools, the abrasive tools are consumed or blunt too quickly, and high accuracy cannot be obtained.
3. Grinding of various material parts sensitive to local thermal stress and thermal shock.
4. Fine grinding and final grinding of large precision workpieces (machine tool guide rails, high-precision machine screws). These workpieces often cause large thermal deformation due to the high grinding temperature, which fails to achieve high accuracy.
5. Fine grinding and final grinding of workpieces (parts of instruments and miniature bearings) produced in large quantities on automatic and semi-automatic machine tools.
6. Grinding of complex profile workpieces (gear shaping cutter, broach, high-precision gear, master, punch) that require abrasive tools with good angular retention.
7. Grinding of profile surfaces of thread cutters and thread gauges (tap, thread roller, thread plug gauge, etc.).
8. Super finishing of difficult-to-process heat-resistant steel workpieces.
9. Grinding of other steel quenching tools.
