Grinding is a machining process improving the surface finish of the job and producing small chips. The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. As shown in the image, the abrasive grains are held ...
Grinding pressure is the rate of in-feed used during a grinding operation; it affects the grade of wheel. A general rule to follow is that as grinding pressures increase harder wheels must be used. George Schneider, Jr., is the author of Cutting Tool Applications, a handbook to machine tool materials, principles, and designs.
Causes & Method of Correction – Grinding Chatter. Wheel grading too hard-Use softer grade or coarser grit. Wheel out of balance-Rebalance after truing operation. Run wheel without coolant to throw off excess water. When wheel is removed from machine store on side to prevent water from setting at lower edge of wheel.
Life of Grinding Wheel When a grinding wheel is applied to the workpiece, the sharp edges of the abrasive grains which are cutting, will, in the end, lose their cutting effect and become dull. At that stage, the abrasive grains should either split or form new edges or it should break away from the wheel exposing the next layer of grains to do work.
Balancing of the spindle and grinding wheel. The balancing of the spindle and grinding wheel is an essential operation to achieve the machining's surface quality and to ensure a long life of a rotary components.
