This machine is used for grinding cylindrical and tapered holes in cylindrical parts e.g. cylindrical liners, various bushings etc. The workpiece is rotated between supporting roll, pressure roll and regulating wheel and is ground by the grinding wheel as illustrated in Fig. 29.19. We provide a large number of solutions for customers in more than 160 countries/regions around the world, and are committed to creating the most suitable solutions for customers. We welcome your inquiry 7/24 hours.

The FGC machine essentially is a five-axis machining center. However, because the work is grinding instead of milling milling in the conventional sense, that is, the machine had to deliver the sort of stiffness that is a key strength of the traditional horizontal platform.

Keep in mind that a grinding wheel is a form of cutting tool, and except in the case of wheel for general purpose grinding, the abrasive, grit size, grade and structure, bond type should be selected to fit the particular job on which the wheel is to be used, just as a cutter, drill or tap is selected for its specific job.

Oct 25, 2011nbsp018332The arc of contact in grinding is the portion of the circumference of the grinding wheel that is in contact with the workpiece. According to Foster, the longer the arc of contact, the more critical wetting becomes. The correct velocity also is very important. A lot of people will flood the grinding area, but this is actually not beneficial.

The external grinding principle is also applied to the internal grinding. In internal centreless grinding the work piece is supported by three rolls. One is the regulating roll, and the other is pressure roll to hold the work piece firmly against the support and the regulating rolls. This is illustrated in the diagram below.

Feb 27, 2015nbsp018332A balanced grinding wheel operates reliable at high peripheral speeds. An unbalanced grinding wheel produces chatter and leaves undue strain on the machine. The problem becomes serious in the wheels of large diameter and needs attention. The unbalancing of grinding wheels occurs due to following reasons Non-uniform density of the wheel material.

Dec 08, 2013nbsp018332INTRODUCTION TO GRINDING PROCESS It is the only economical method of cutting hard material like hardened steel. It produces very smooth surface, suitable for bearing surface. Surface pressure is minimum in grinding. It is suitable for light work,which will spring away from the cutting tool in the other machining processes.

About Steel Grinding. Steel grinding is a process that moves a grinding wheel or segment in a plane while the wheel contacts the work piece and removes material to create a flat surface. Parts may require surface grinding for several reasons, including Flat surface is required Accurate thickness tolerance is needed Smooth surface finish is required.

Grinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time.
