What are the differences between end mills and keyway cutters?
The difference between end mills and keyway cutters is mainly based on their primary use. The end mill generally has more than three cutter teeth, keyway milling cutter is generally two teeth. The end mill is mainly used to process the surface, and the side blade requires smooth cutting, so it is often made more than three teeth. Because the cutter tooth is spiral, more than two are involved in the cutting at the same time, the work is smooth, the chip removal is good, the machining efficiency is high, and the machining surface is easy to obtain. Keyway milling cutter is mainly used to machining keyway, a milling keyway width size requirements meet the technical requirements, in order to overcome the influence of radial cutting force, the cutting tool design for cutter teeth of two mutually symmetrical, in the milling, cutting force distribution in the two tooth distance of the formation of couple, radial force offset each other so, can a processing of the same width and the diameter of the rotary cutter keyway. In addition to direct processing of the two ends closed keyway, length of the end edge of the keyway milling cutter directly to the rotary center of general milling cutter, can directly drill into the workpiece along the axial direction, and the end of the cutter rotating center part is in general no edge zone.
The main difference between the end milling cutter and the keyway cutter is that the end face of the end milling cutter is provided with a center hole, and the end face of the keyway milling cutter is without a central hole. Therefore, the end mill can not directly down the feed, down into the deep, the center hole will withstand. The keyway cutters can be drawn down directly. In addition, keyway milling cutter, as its name suggests, is used for milling keyway, so the size accuracy of its outer diameter is very high, generally can reach the accuracy of about 0.01mm.
The main difference between end mills and keyway cutters is that:Vertical milling cutter is used to produce flat or cylindrical surface, so its diameter size is relatively loose, and is used for machining keyway keyway milling cutter, its diameter size directly affects the quality of fit keyway and key, so more stringent tolerances; in order to have keyseats hole, only two blade, cutter is more than two of the cutting edge.The end face of the end milling cutter is provided with a central hole, and the end face of the keyway milling cutter is without a central hole. Therefore, the end mill can not directly down the feed, down into the deep, the center hole will withstand. The keyway cutters can be drawn down directly. In addition, keyway milling cutter, as its name suggests, is used for milling keyway, so the size accuracy of its outer diameter is very high, generally can reach the accuracy of about 0.01mm.
