Oct 02, 2018While each cutting particle on the grinding wheel experiences a low force relative to other modes of grinding, the force imparted to the machine and part overall is likely to be high. Compensating for the heavy depth of cut in creep-feed is a traverse rate (feed rate) that is low, often on the order of 5

Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods. Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles, intricate contours or cavities in hard and

Sep 15, 2021A thread-grinding machine closely resembles a cylindrical grinder in appearance. It incorporates a precision lead screw to produce the correct pitch or lead on the threaded part. Thread-grinding machines also have a means of dressing or truing the cutting periphery of the grinding wheel so it will produce a precise thread form on the part.
