Challenge: Elevate the face milling level with the new milling cutter concept and offer a variety of different models to meet specific needs.
Solution: A unique and innovative multi-cutting face milling cutter – a high-tech cutting tool technology.
Face milling is the creation of a flat area on a part that is the most basic and most frequently used method in a milling process. Although the milling is relatively simple, the factors involved are surprising. The success of milling surfaces needs to be measured in terms of process safety, production efficiency, machining costs, tool life and tool versatility.
Today, most of the factors in face milling have been incorporated into the design of the milling cutter, and the mechanical processing plant only needs to select the corresponding tool. For milling cutters that are purely used for face milling, the 45 degree lead angle is the most suitable and has many advantages:
(1) balanced axial and radial cutting forces;
(2) Good cut-in and cut-out features;
(3) The solid cutting edge can meet the demanding cutting requirements;
(4) Good surface finishing ability;
(5) The effect of having thin chips helps to increase the feed rate.
In the mid-1990s, the face milling concept took a step forward, mainly in two directions. One is the focus on performance, results and reliability. This is a square blade with 4 cutting edges with a 45° lead angle. Another direction is to maximize the number of available cutting edges, typically with 8 cutting edges per insert. However, since the tool cost only accounts for 3% of the manufacturing cost, especially considering the limitations associated with the octagonal concept at the time, it is most appropriate to have four cutting edge inserts that are more efficient.
For many years, the CoroMill 245 concept of four cutting face milling cutters has become the most widely used face milling cutter and industry benchmark. In fact, it is highly recognized and developed in two models: one for depths of up to 6 mm; the other for depths up to 10 mm, and is suitable for all materials, from roughing to mirror finishing. Processes, as well as milling cutter diameters of various sizes. However, it is always a good thing to incorporate improved tooling costs into this concept. If the CoroMill 245 is equipped with eight cutting edge inserts, this problem has long been solved. But the principle of the CoroMill user is that there should be no compromise on performance and reliability issues. Today, extensive R&D work has incorporated these two development directions (eight cutting edge inserts and uncompromising performance) into the same face milling concept.
The CoroMill 345 is a unique new face milling cutter concept that compromises reliability, efficiency, productivity or tooling costs. This proven new generation of 45 degree face milling cutters are equipped with double-sided inserts with 4 cutting edges on each side.
So, what is the difference between CoroMill 345 and how are all the face milling properties combined?
Like the CoroMill 245, the CoroMill 345 cutter retains the characteristics of non-destructive stability and strength. The CoroMill 245 is still a complementary option for some applications. CoroMill 245's square blade concept is the basis for improved indexable insert technology, the macrostructure of the cutter and the microscopic groove of the insert. CoroMill 345's insert cutting edges are advanced and vary in depth. When the depth of cut is small, the axial inclination of the positive rake angle is increased, and a gentle cutting action with a small axial pressure is generated, and the cutting force acts on the workpiece. As the depth of cut increases, the straighter edge portion continues to function, giving the blade a more robust structure for a highly safe effect, especially in difficult-to-machine conditions.
The challenge for CoroMill 345 is how to double the number of new intelligent cutting operations to the number of existing cutting edges per insert. The solution to overcome this challenge is to use a blade with four cutting edges per face and a basic shape with a negative rake angle. A knife pad with a special support island has been developed to match the blade's joint surface to ensure the stability of the blade on the body. The body is carefully calculated and designed to provide the right balance of support and accommodate more blades. CoroMill345 also has an additional pitch selection (HX) that increases metal removal by increasing the number of teeth in the cut. This unique development of milling technology has improved the new level of performance, which is confirmed by the sound during processing. As the preferred universal face milling cutter, CoroMill 245 has dominated face milling to date. CoroMill 345 is considered to be an excellent successor to CoroMill 245.
Maximize the face milling potential of the coromill 345 (1) Use down-cut milling as much as possible for optimum milling results.
(2) Select the most suitable tool diameter according to the milling condition and power; usually, the milling width should be two-thirds of the tool diameter.
(3) Refer to the position of the milling, properly place the milling cutter, taking into account the cutting and cutting of the milling cutter, and ensure that the center line of the milling cutter is not on the center line of the milling surface.
(4) If the face milling area is larger than the tool diameter, select the tool path that will keep the milling cutter in contact as much as possible.
(5) If the tool direction is to be changed while the milling cutter is in full cutting, the radial tool path must be taken into account in order to maintain the cutting, avoiding the tendency to pause and vibrate.
(6) Select the most suitable milling cutter pitch, and ensure that there are not too many teeth in the cutting from the power angle, but also consider the feeding ability to ensure sufficient number of teeth.
(7) According to the recommended maximum chip thickness of the milling cutter, select the most suitable feed per tooth to maximize the feed of the table.
(8) Observe the wear of the cutting edge to optimize the cutting speed and feed capacity to ensure tool life and safety.
Conclusion: CoroMill 345 is an advanced tooling concept that is suitable for both small batch processing and high volume special processing. It is versatile and has a wide range of optimization possibilities, from rough machining in harsh conditions to mirroring with wiper blades, from small low-power devices to large high-power devices.
