End Mill

In the metal processing industry, an end mill is a milling cutter (or milling tool), which is a cutting tool that removes work piece material by rotating the tool itself during industrial milling. It differs from drilling tools in terms of corresponding applications, geometry and production. The drill bit can only be cut in the axial direction, but due to the multiple axes installed on the machine body, the milling cutter can usually cut in various axial directions. Although some cannot cut axially, most can perform multi-axis milling.
 
For milling machines and machining centers, end mills are used in contour milling, tracer milling, face milling, and many other milling applications that can form complex contour cuts and simple curve machining. There are many substances that constitute end mills, but most are stainless steel and tungsten carbide. If the work piece is very hard, some may be diamonds.

In the machine tool industry, there are several sub-industries, such as mechanical products, parts, accessories and tool parts. Most cutting machines are designed for turning, drilling, milling and other cutting operations. In the tool market, an end mill is a milling cutter that is a cutting tool for industrial milling applications.

 

Distinctive functionality

End mills differ from drills in application, geometry and production. At the same time, drilled items can only be cut in the axial direction, while milled items can usually be cut in all axial directions, but some items cannot be cut axially in some cases. In fact, end mills are used in milling applications such as profile milling, tracer milling and face milling. In the market, there are various end mills and face mills, such as center cutting and non-center cutting. In practical applications, more and more cost-effective insert cutting tools have replaced traditional solid end mills. In addition, end mills are sold in inch, metric, and cutting diameters.

 

Installation

As a convenient tool, end mills are usually installed on high-speed milling centers. High-speed machining centers are highly developed machine tools that can handle many precision machining tasks at once. At first, the machine center was developed from a milling machine in the middle of the last century. The development of this particular type of machine tool has developed well in the industry. Since then, the machine tool center has been widely used in various industries, and has made extensive efforts for the industry.
 
Regarding the milling process, it is a machining process that uses a rotating tool to remove work piece material by advancing the tool into one or more work pieces. This processing method can be done in different directions. In addition to turning, milling also covers a variety of operations, and the range is very wide, from a single small part to heavy and large milling operations.
 
The end mill can be installed on the turret system. In addition to the power turret, the tool magazine and automatic tool changer (ATC) are also the best-selling products in the combination. Many tool suppliers that provide tool magazines and ATC systems are committed to provide customers with the best tool processing time based on cycle time engineering design, and can help manufacturers meet order requirements.
 
Compared with global competitors, Taiwan’s proprietary technology can provide comprehensive services to the best-planned global customers according to local conditions, so products equipped with machines or accessories have actually been upgraded to the latest modern version according to order requirements. Spindles, chucks and corresponding hydraulic cylinders are also very developed in Taiwan. Along with the CNC lathe market, there are a bunch of lathe products and accessories that have been widely distributed in different industrial fields and applications around the world.

 

The similarity to turning center

Similar to turning, milling is one of the most commonly used machining methods, providing precise tolerances. Because of its practical value, the development of milling methods is very popular in industry. Traditional lathes are relatively difficult to achieve the production and effective performance of work pieces with complex profiles. With this expectation, the following development and machine center concepts were gradually formed.
 
The term "machining center" can be used to describe various CNC (computer numerical control) drilling and milling machines, which are equipped with some key but sometimes optional accessories. These accessories are equipped with the machine body, such as tool magazine, ATC (automatic tool changer), electric turret, CMM (coordinate measuring machine), multi-axis table, to name a few. The classification of machining centers can be roughly divided into two categories: vertical and horizontal, and there are other categories in the inventory of machining centers. The vertical machining center is the vertical alignment of its structure, and the workpiece is processed by a cutting tool that moves vertically. With the vertical design, the weight of the workpiece will help it be firmly positioned on the fixture to make a heavier vertical cutting path without worrying about path deviation.
 
In addition, with the help of the power turret, the cycle time is greatly reduced. The machining of work pieces in machining centers is usually not circular, but other complex profiles. The former can be handled in a more efficient manner by a lathe with a powered turret.

 

Milling speeds

The speed of the spindle is a key parameter that determines the performance of the machining center. Standards for high speed are different around the world. Therefore, when customers are looking for the best high-speed machining center for their production line, they need to discuss the specifications further.

 

Summary

Since the invention of the milling machine, the human industry has undergone a series of major changes in the way we manufacture tools and objects. End mills are very important to us. The final quality of the workpiece can be determined and tightly connected to the work spindle for processing. The end mills must be used carefully according to the standard, and the end mills must be checked every time in order to make full use of the milling machine and end mill.
