What Is a Milling Cutter?
Milling cutters are rotary tools with one or more teeth for milling. During the work, each cutter tooth intermittently cuts off the remaining amount of the workpiece. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting workpieces on a milling machine.
- Clamping of milling cutter
- Most of the milling cutters for machining centers accept the spring clamp set clamping method, which is in a cantilever shape when used. Being
- Basic requirements for materials for milling cutters
- 1) High hardness and
Milling equipment maintenance
- Milling cutter
- The situation will be serious when the cutter axis and the workpiece edge line coincide or are close to the workpiece edge line.
- 1. Check the power and stiffness of the machine to ensure that the required cutter diameter is within
- Milling cutter
- 2. The overhang of the tool on the spindle is as short as possible to reduce the impact of the milling cutter axis and the workpiece position on the impact load.
- 3 Use the correct milling cutter pitch suitable for this process to ensure that there are not too many inserts engaged with the workpiece during the cutting to cause vibration. On the other hand, ensure that there are sufficient inserts when milling narrow workpieces or milling cavities. Engage with the workpiece.
- 4 Make sure that the feed per blade is used so that the correct cutting results are obtained when the chips are thick enough to reduce tool wear. Indexable inserts with positive rake grooves for smooth cutting results and lowest power.
- 5. Choose a cutter diameter suitable for the width of the workpiece.
- 6. Use the correct main declination.
- 7. Place the cutter correctly.
- 8. Use cutting fluids only when necessary.
- 9. Follow tool maintenance and repair rules and monitor tool wear.
Milling cutter mould
- Mold cutters are used to machine mold cavities or punch forming surfaces. The die milling cutter is evolved from an end milling cutter. According to the shape of the working part, it can be divided into three types: conical flat head, cylindrical ball head and conical ball head. Carbide mold milling cutters are very versatile. In addition to milling various mold cavities, they can also replace the use of files and grinding wheels to clean the burrs of cast, forged, and welded workpieces, as well as the finishing of certain forming surfaces Wait. The milling cutter can be used on pneumatic or electric tools, and its production efficiency and durability are dozens of times higher than those of grinding wheels and files.
Main purpose of milling cutter
- Broadly divided into:
- 1. Flat head milling cutter for rough milling to remove a large number of blanks, small area horizontal plane or contour fine milling.
- 2. Ball-end milling cutters for semi-finish and fine-milling of curved surfaces; small ball-end milling cutters can finish milling chamfers with steep / straight walls and irregular contours.
- 3 The flat-end milling cutter has chamfers, which can be used for rough milling to remove a large number of blanks, and also for fine milling of small flat chamfers (relative to steep surfaces).
- 4 Formed milling cutters include chamfering cutters, T-shaped milling cutters or drum cutters, tooth cutters, and inner R cutters.
- 5. The chamfering cutter and chamfering cutter have the same shape as the chamfering cutter, and are divided into milling cutters for round chamfering and chamfering.
- 6. T-shaped knife can mill T-shaped groove.
- 7. Tooth cutters, milling various tooth shapes, such as gears.
- 8. Rough leather cutter, rough milling cutter designed for aluminum-copper alloy cutting, can be processed quickly.
Milling FAQ
- Milling cutter
- 1. Overcutting:
- Reduced depth and width during cutting
- 2. Lack of accuracy of machine or fixture:
- Repair of machines and fixtures
- 3 Machine or fixture lacks rigidity:
- Change machine \ fixtures or cutting settings
- 4 Too few blades:
- Using a multi-edge end mill
- Milling cutters have developed very quickly. They are called rotary tools in the industry. As shown in the figure, they are only solid carbide milling cutters. In fact, more milling cutters are used in hole processing and cavity processing. Most of these milling cutters are equipped with blade !! [7]
