The PCD cutter's tool body is typically constructed from highspeed steel or tungsten carbide. In milling machines, the end mill is typically used to process surfaces, steps, grooves, form surfaces, and cut workpieces after being tipmounted with a PCD blade. The blade's PCD material is a variety of polycrystalline diamonds.
WhatsApp: +86 18838072829Aluminum is one of the most popularly used metals in manufacturing industries, but grinding aluminum can be challenging as it tends to melt under the heat generated during the grinding operation. The primary reason for overheating of the workpiece is the use of an improper grinding wheel and lack of coolant .
