Product Description Machine IntroductionEvery centerless grinder is derived from application requirements.1.The HC full series of centerless grinders have corresponding solutions for a grinding range of 0.08 to 200mm.2.Hydrodynamic spindles, hydrostatic spindles, and bearing spindles are available for selection.3.The patented products of the academician workstation - hydrostatic guideways and rectangular square guideways - are provided for different applications.4.The CNC series with various combinations of 1 to 6 axes can meet various grinding requirements. Machine ApplicationsThe applications of centerless grinders are everywhere.1.Through grinding: cylindrical shaft parts of various sizes2.Stop grinding: multi - stepped parts of various sizes, parts with complex shapes Product StructureDouble V tracks, rectangular square tracks, and hydrostatic tracks are used for different machine models, maximizing their respective advantages.1.Double V TracksThe double V tracks go through the manual scraping process. The slide plate is always fully attached to the guide rails of the machine tool bed throughout the entire stroke range, ensuring excellent movement performance within the effective stroke. The double V track structure is stable, has a low maintenance cost, and offers a high cost - performance ratio.2.Rectangular Square TracksRectangular square tracks have unique advantages when applied to large - scale centerless grinders. The enlarged track surface is combined with a wear - resistant plastic - coated slide plate, achieving both the sensitivity of sliding and ultra - high rigidity.3.Hydrostatic TracksThe hydrostatic tracks are products designed and developed by the Fuxincheng Academician Workstation and have successfully applied for invention patents. The track design adopts orifice throttling. During operation, the track floats in a high - pressure oil film, with a friction coefficient less than 0.001, no wear, and a long service life. The hydrostatic tracks can achieve a feed accuracy of 0.0001mm.4.Track · Slide PlateThe track · slide plate, combined with a high - precision ball screw, can be equipped with manual and automatic fine - feeding, with an accuracy of up to 0.001mm.Corresponding lubrication oil channels and lubrication systems are designed for various tracks to ensure normal operation of the tracks and safety against wear.Hydrodynamic Spindle / Hydrostatic Spindle1.The core shaft of the hydrodynamic spindle is made of Japanese SNCM-21H alloy steel through more than ten processes. It is manually and repeatedly matched, ground, scraped and assembled with the alloy bearing, and is equipped with a lubrication system to ensure the rotational accuracy and rigidity of the spindle.2.The hydrostatic spindle is a patented product of the academician and expert workstation. The spindle is supported by a high-pressure oil film, with no contact friction, reducing power consumption and improving accuracy and shock absorption performance. It performs even more outstandingly in high-speed cutting. Rolling bearing spindleSelect ultra-precision double row cylindrical roller bearings, lubricated with grease, requiring no maintenance in normal times. The unique design eliminates the need for a flange, making it suitable for high-precision grinding.Trimming seat / Grinding wheel and regulating wheel trimming1.Trimming seatThe trimming seat is made of a special alloy casting with hand-scraped patterns. It is driven by a variable-speed hydraulic pressure or can also be driven by a servo motor equipped with a precision ball screw for stepless speed change.2.Grinding wheel and regulating wheel trimmingAccording to the requirements of the workpiece grinding process, the trimming of the grinding wheel and the regulating wheel is divided into diamond pen trimming, diamond disc trimming, and diamond profile roll trimming. Under special circumstances, the diamond disc trimming wheel can be replaced with an ordinary silicon carbide grinding wheel to trim a new diamond grinding wheel.CNC system and softwareThe CNC control system is selected for the CNC centerless grinder. Precision ball screws are used in combination with servo motors for numerical control.It can achieve automatic feeding of the upper and lower slides according to the grinding process, and realize automatic dressing and automatic compensation of various shapes of the grinding wheel and regulating wheel. This greatly improves the processing ability of the centerless grinder for workpieces with complex shapes and reduces the difficulty of manual operation.A variety of automatic loading and unloading and automatic detection solutions are available for matching and selection, enabling fully automatic processing and production of high-precision parts.Through-type grindingThrough-type grinding is suitable for all kinds of round pipes, round bars, rods and valve cores. Different automated feeding and discharging devices can be matched according to the workpiece size. It has high grinding efficiency, reaching several meters per minute, which can greatly reduce the production cost.Stop-type grindingStop grinding is suitable for parts with multiple steps and complex shapes. According to the characteristics of the workpiece, different ways of dressing the grinding wheel can be selected, and different automatic feeding and discharging devices can be designed. This greatly reduces the operation difficulty and improves the production efficiency.
