Road Milling Tools Improve Processing Stability
- Jul 19, 2017 -

Road Milling Tools As manufacturers continue to introduce products with more features and higher performance, the components that make up these products are becoming more and more complex, and their manufacturing is becoming more and more difficult. In addition to complex surface profiles and increasingly stringent dimensional tolerances, these components are often made of high-performance materials with good strength and reliability, and these material properties adversely affect their cutting performance.

Tool manufacturers are also constantly developing new tools that maximize processing efficiency. The technological advancement of Road Milling Tools is an example of this effort. For a long time, the overall carbide cutter provides users with a high metal removal rate and excellent machining accuracy. However, the integration of such tools determines the need for grinding after they need to re-grinding. Replacing the tool will disrupt the production process and spend a lot of time and money. In addition, the use of re-grinding of the milling cutter need to modify the parameters of CNC machining procedures, and in order to process different parts profile, you may need to choose a more suitable tooth type of different types of milling cutter.

As a better alternative to the overall cost of the cutter, the tool manufacturer has developed a cutter that can be indexable and replaceable blades. When the cutting edge of the blade is worn,Road Milling Tools simply transfer the blade to the new cutting edge. When the blade cutting edge is completely worn out, it is possible to quickly replace the blade without having to remove the blade from the machine, and to insert the blades with different geometries on the same cutter body to accommodate the contours of the different parts need.

The geometries of indexable inserts are also evolving. Many of the indexable inserts have a cutting edge on the top and bottom surfaces. After this double-sided blade is turned, it can be turned over to the other side, and the number of available cutting edges is doubled. However, the design of the double-sided blade does not include the inclination angle of the blade body after the cutting edge, so that the cutter can not be cut with the front rake angle.

In the front rake cutter, the main body of the blade is tilted rearwardly from the cutting edge so that the cutting edge can cut the workpiece material. In contrast, the blade body of the negative rake cutter is tilted toward the workpiece, and the milling cutter is basically pushing the material to be cut. The design feature of the double-sided blade determines that the cutting edge must be close to the workpiece at a negative angle.

Negative front horn Road Milling Tools can provide some benefits: they have better strength, can withstand greater chip load and cutting force, so more suitable for rough milling,Road Milling Tools intermittent cutting and processing of high hardness, high abrasive workpiece material (Such as cast iron). As a result of the use of multi-cutting blade can reduce the cost of the tool, so easy to work in the workpiece material for a simple two-dimensional milling, double-sided negative blade is a good economic choice.

However, since the negative front horn cutter is primarily pushed (rather than shearing) the working material, it will produce a large amount of cutting force and a large amount of cutting heat. If the machine's power is low or the rigidity of the entire processing system is insufficient,Road Milling Tools it will adversely affect the final machining accuracy. For example, the cutting force generated by the negative rake cutter may distort the thin-walled workpiece.

In contrast, the positive rake cutter achieves free cutting, minimizing the cutting pressure, and often milling the negative profile of the negative front horn cutter that can not be reached. The right angle blade edge has excellent machining flexibility and can be used to perform a variety of processing,Road Milling Tools including milling, profiling, helical milling and slope milling. It is important to reduce the cutting force as much as possible when milling difficult-to-machine materials such as titanium alloys, Inconel alloys and a variety of stainless steels on old machine tools or rigid machine tools, while using the front rake cutter helps to improve processi
