•Before doing precise work on a milling machine, one must locate the edges of a part accurately. An edgefinder is designed to help you do this. •An edgefinder is composed of two concentric cylinders, spring loaded together. To use it, offset the two halves slightly so that there is a wobble as it spins. Then, move the part into the tool slowly.

بیشترGrinding is one of the most important manufacturing process for high precision parts. Grinding characterized by low material removal rate and high surface finish is an abrasive machining process. Geometrically undefined grits of grinding wheel influences part surface finish. Cutting edges worn out during grinding are retained by timely dressing.
بیشترThe grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.
