Q:For example, to do a 14 hole, the depth of 12, drilling milling cutter is 12, how to do? Is not to make a hole, hit bottom?

Very simple ah, first a 11.5 deep bottom with 13 bits, and 12 mills with G03 go round a deep hole can be, if you can directly through hole with a drill.

Q:What is meant by end mills? What is the difference between end mills?

The end mill is a milling cutter with a top surface. It is of a disk type and can only be cut with an end face. The main cutting edge of the end milling cutter is cylindrical surface, and the cutting edge on the end face is an auxiliary blade. The end mill without a center edge can not feed along the axial direction of the cutter. According to the national standard: the end milling cutter diameter is 2-50 millimeters, can be divided into two kinds of coarse teeth and fine teeth. Diameter 2-20 is straight handle range, diameter 14-50 is taper handle range.

Q:The trimming method of straight shank 3 edge end milling cutter has the best video frequency

Hand grinding? With your right hand, rotate your left hand

Q:Why does the saw milling the workpiece have a noise?

The basic tool is not fast, need to be repaired ~ ~ or there is this possibility; the workpiece is not clamped

Q:Milling cutters are divided into several kinds

1. flat milling cutter, rough milling, to remove a large number of rough, small area, horizontal plane or contour milling;2. ball end mill for surface finish milling and fine milling. The knife can be used to finish milling the small chamfer of the steep surface / straight wall.3. flat milling cutter with chamfering, can do rough milling to remove a lot of rough, but also fine milling, fine surface (relative to the steep surface), small chamfer.4. forming milling cutter, including chamfering cutter, T shape milling cutter or drum type cutter, gear cutter, inner R knife.5. chamfer knife, chamfer knife shape and chamfer shape are identical, divide into milling circle, chamfer and slant chamfer milling cutter.6.T type cutter can be milled with T groove;7. gear cutters, milling out various tooth types, such as gears.8. rough skin knife, aiming at the design of Al Cu alloy cutting rough milling cutter, fast processing

Q:What milling cutters are used to process the step surface of the milling machine to ensure the vertical accuracy of the two surfaces at the same time?

Preferred alloy knife, but depends on the size of the processing margin, to 3.2 of the words, you have to go slow down knife, end mills can also reach I have tried.

Q:Do you have milling cutters with outer diameters of less than or equal to 1mm?

A lot of, do the milling cutter has, I have, but the general minimum is 0.3mm,There are also very few manufacturers doing 0.2mm knives

Q:What's the difference between a cutter and a drill bit?

Popular point of the milling cutter is the processing plane, with the blade of the ground is flat, so you can not directly like a brick vertical feed, and the drill has a 120 reading angle can be vertical feed, but not parallel washing

Q:The keyway milling cutter (taper shank) generally has a blade length of 22~50 and a straight shank of 5~25, depending on its diameter. The bit is generally 78~270 (taper shank) and the straight shank is 6~100, depending on the diameter

Q:When milling a workpiece, if the direction of the rotation of the cutter is opposite to the feed direction of the workpiece, what is the reason?

Reverse milling. Conversely, it becomes progressive milling. Thank you
