During the grinding process, the same pressure is maintained in real time by the pressure device, which ensures the flatness of the workpiece processing and improves the processing efficiency of the entire processing process.

The invention discloses a grinding workbench. The grinding workbench comprises a base (1), a push rod (4) and a platform seat (7) arranged at the upper end of the push rod (4). The lower end of the push rod (4) is provided with a first magnetic patch (9). A second magnetic patch (10) is arranged below the first magnetic patch (9) and has magnetism opposite to the first magnetic patch. A secondary support part used for providing a thrust supporting effect is arranged below the second magnetic patch (10).The grinding workbench has following beneficial effects: due to a simple structure and low weight, the grinding workbench is adapted to a wire-drawing die in the larger size range for grinding and polishing so that border applicability is obtained and convenience is achieved so that working efficiency is improved and working cost is reduced.

The Honing Machining Method of Carburizing Holes of Aero-engine Tappet Guide Sleeves
ActiveCN112743442BUniform grinding forceHigh cooling frequencyGrinding drivesGrinding feed controlNumerical controlSurface finish
The invention discloses a method for honing a carburized hole of a lifter guide sleeve of an aero-engine. A numerical control boring tool is used to process the carburized hole of a lifter guide sleeve to remove the allowance to 0.2 mm to 0.3 mm, and the lifter guide sleeve is installed on the On the honing machine, align the carburized hole of the tappet guide bush, and process the carburized hole four times until the surface finish of the carburized hole is Ra≤0.02. The four honing processes include rough honing, semi-finishing honing, and fine honing Processing and ultra-fine honing processing, and the honing process parameters are optimized, so that there is no burn or crack defect in the carburized hole of the tappet guide bush, and the internal surface finish of the carburized hole of the tappet guide bush is close to the mirror level. The honing method of the carburized hole of the tappet guide sleeve of the aero-engine has high processing efficiency, uniform grinding force, high cooling frequency, sufficient cooling, no burns and crack defects, and the surface finish of the inner hole is close to the mirror surface level.
