Hard to Pick Out Suitable End Mills? These Basics May Help

The main cutting edge of the end mill is a cylindrical surface, and the cutting edge on the end face is a sub-blade. When the end mill without the center edge is working, it cannot make a feed motion along the axial direction of the milling cutter. End mills are currently widely used in various sectors such as automobile manufacturing, logistics, molds, machinery, etc., and because of the increasing use of various aspects, the application requirements are also increasing. Therefore, various problems that are common in the use of end mill applications are summarized and answered.

[Q] What is the difference between a reamer and an end mill?

[Answer] The reamer is a straight edge and the end mill is a spiral edge. The milling cutter has a bottom edge and the reamer does not! The reamer is used to finish the hole, while the milling cutter can be milled, washed, and side washed! Use is different!

[Q] What are the steps for milling the end mill?

[Answer] First install the end mill, then move the end mill to the top of the workpiece to be milled, gently lick the upper surface of the workpiece with the end teeth of the end mill, and then lift the dial of the milling machine Zero; then move the end mill to the side of the workpiece, lower the end mill to the side of the workpiece, then gently lick the side of the workpiece with the side of the cutter, and set the handle dial in the corresponding direction to zero, then Start milling the steps. The depth of the knife is determined according to the size of the machining allowance, the strength of the material, and the size of the milling cutter. After eating from at least one knife, it is completed by dividing into several knives.

[Q] What is the difference between an end mill and a keyway cutter?

[Answer] The main difference between the end mill and the keyway cutter is that the end mill is used to machine flat or cylindrical surfaces, so its outer diameter is relatively loose, and the keyway cutter is used to machine the keyway. The outer diameter dimension directly affects the mating quality of the keyway and the key, so the tolerance is stricter; in addition, the keyway milling cutter has only two blade belts for machining holes, and the end mill has more than two blade belts. The end face of the end mill has a center hole, and the end face of the keyway cutter has no center hole. Therefore, the end mill is not able to feed directly down, deep down, and the center hole will withstand. The keyway cutter can be fed directly down. In addition, the keyway milling cutter, as the name implies, is used to mill the keyway, so the dimensional accuracy of the outer diameter is very high, and generally can reach an accuracy of about 0.01 mm.
