Hard to Pick Out Suitable End Mills<\/a>? These Basics May Help<\/strong><\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

\"endmills<\/figure>\n\n\n\n

[Q] How should the \u00d812 of the two teeth of the end mill be ground?<\/p>\n\n\n\n

[Answer] First, the sand wheel should be ground, the edge of the grinding is a little angled, the milling cutter, the blade should pay attention, the outside should be higher than the inside… The slope inside should not be too oblique, probably just like this, this still has to grind more Practice only.<\/p>\n\n\n\n

[Q] What is an end mill and what is a disc milling cutter? What is the difference?<\/p>\n\n\n\n

[Answer] End mills are generally used for milling end faces, rather than keyway cutters for milling slots. The disc milling cutter is mainly used for milling large end faces, because the straight milling of the disc milling cutter is generally large, the milling end face is faster for milling, and the saw blade milling cutter is generally used for milling.<\/p>\n\n\n\n

[Q] Why can’t the end mill cut vertically?<\/p>\n\n\n\n

[Answer] When the end mill rotates, the midpoint of the bottom edge is relatively static. It does not have any machinability and chip removal, so it cannot be cut vertically.<\/p>\n\n\n\n

[Q] How is the feed rate of the \u0905\u0902\u0924 \u091a\u0915\u094d\u0915\u0940<\/a> determined?<\/p>\n\n\n\n

[Answer] The selection of cutting amount should be considered together with the factors such as tool, workpiece and machine tool. The main cutting edge of the end mill is the peripheral edge. The feed per tooth is generally about 0.1 during finishing. The amount is generally selected from 0.25 to 0.3 mm. Specifically, it should be matched with the cutting parameters such as cutting speed, axial depth of cut and radial depth of cut.<\/p>\n\n\n\n

[Q] What is the difference between the end mill and the ball end mill and its selection principle?<\/p>\n\n\n\n

[Answer] End mills and ball end mills, one is the ball head, one is the flat bottom, the end mill is mainly for conventional machining, and the ball end milling cutter can be used for milling the surface.<\/p>\n\n\n\n

[Q] What is the difference between the collet for the end mill and the collet for the tap? Do you have to use the company handle when tapping?<\/p>\n\n\n\n

[Answer] Although the collet for holding the straight shank end mill can be used to hold the tap for rigid tapping, the effect is not good, generally the small diameter tap is no problem; the ER collet for the tap is with a square groove That is, the flat-tailed limit function of the tap handle is now available in general tool manufacturers.<\/p>\n\n\n\n

[Q] What is the difference between a reamer and an end mill?<\/p>\n\n\n\n

[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!<\/p>\n\n\n\n

[Q] How is the feed rate of the end mill determined?<\/p>\n\n\n\n

[Answer] The selection of cutting amount should be considered together with the factors such as tool, workpiece and machine tool. The main cutting edge of the end mill is the peripheral edge. The feed per tooth is generally about 0.1 during finishing. The amount is generally selected from 0.25 to 0.3 mm. Specifically, it should be matched with the cutting parameters such as cutting speed, axial depth of cut and radial depth of cut.<\/p>\n\n\n\n

[Q] What are the steps for milling the end mill?<\/p>\n\n\n\n

[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.<\/p>\n\n\n\n

[Q] What is the difference between an end mill and a keyway cutter?<\/p>\n\n\n\n

[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.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
