Square End Mills
Square end mills are used for rough milling, removal lots of blanks, finishing of small horizontal planes or contours.
The two-edged milling cutter is specially used for keyway machining. It not only has better chip removal performance for keyway machining, but also has the function of punching small batches and small processing volumes.
Carbide corner radius end mills have R-angle protection on the cutting edge, it has smooth cutting and long tool life, and their strength is higher than that of flat end milling cutters, which is not easy to chip. Besides, compared with ball nose cutters, the axial direction has a larger proportion of cutting under the same strength.
It can do rough milling to remove a lot of blanks, and finely mill small chamfers on fine flat surfaces, relative to steep surfaces.
Ball Nose End Mills
During the machining process, the center of the ball nose end mill always remains stationary, and the contact part between the center and the workpiece is not milling but grinding. Using a ball cutter can obtain a more stable processing state, the surface finish of the workpiece is better.

Ball nose end mills are widely used in various curved surfaces and arc groove semi-finishing and finishing processing. It has high temperature resistance, the maximum temperature to maintain cutting performance is 450-550/500-600 degrees Celsius. For more complex surface roughing, you can use 4-flute ball nose end mills.

How to choose the right face milling operation?2022-11-01T02:59:35+00:00

Since there are multiple options to combine particular tools and face milling operations, you may need some explanations on how to choose one. Here are some factors to pay attention to while making a decision:

Workload: Some types of face milling operations, like finishing with wiper inserts, suit the manufacturing of large batches of products better. It is correct only when the milling operations go with a combination of proper cutters. General face milling is an ideal option for mixes of small batches of components.

Your particular intent: For example, to remove large amounts of material rapidly and roughly or achieve the highest precision possible. Guide your choice accordingly.

Type of workpieces: In case you ordered castings, be prepared to apply for heavy-duty milling first. But if you have already prepared components, you can go with bare general face milling.

Design of a workpiece: It is highly inadvisable to mill over pre-drilled holes, for example. But the consistency of high feed machining consistency over the surface will severely deteriorate if applied to such a component. Heavy duty and general face milling are less demanding in this aspect.

Design of a finished component and technical requirements: It is frequent that you cannot achieve high precision by using, for example, heavy-duty or high feed milling. So be sure the chosen method meets the requirements set to the finished component’s design. Also, thin-walled components can be produced only by means of general face milling or finishing with wiper inserts (ineffective).

Material of a workpiece: Consider that high feed milling can be performed over the thick sheets of the durable metals by appropriate tooling. So, if you are unsure that a workpiece will withstand increased temperature and pressure, better go with general milling or finishing with wiper inserts.

You can make the decision regarding the choice of a face milling process alone. But do not forget to select an appropriate cutter with a sufficient entering angle as well as per their characteristics above.

What is fast feed milling? and what are the main factors to consider?2022-10-28T01:54:08+00:00

Fast feed milling is a machining method that combines a shallow depth of cut with a high feed rate of up to 2.0 mm per tooth. This combination maximizes the amount of metal being removed from a part and increases the number of finished parts in a given time.

Indexable tools with a low-pressure angle of approx. 10°to 15° are often suitable for high-speed milling. Using a low-pressure angle reduces the chip thickness by up to 80 percent compared with tools with a 90° pressure angle. In this type of machining operation, feed rates per tooth (fz) of well over 1 mm are common. A further advantage of high-feed milling cutters is that the cutting forces flow almost entirely in the direction of the spindle. The result is minimal vibration during roughing operations with large overhangs.

A toric tool can imitate these effects. If the depth of cut (ap) is smaller than the cutting radius, the effective pressure angle decreases. The smaller the depth of cut, the more the distribution of forces shifts in the direction of the spindle.

What is carbide end mill?2021-09-28T06:56:36+00:00

Carbide endmill is an industrial rotating cutting tool that can be used for milling operations, which is made from tungsten carbide (WC) and cobalt (Co) materials. They are also commonly referred to as a “carbide milling bit”. Center cutting end mill can be used for plunging operations (axial milling), and can also be used in side milling operations (radial milling). Non-center cutting bits may only be used in side milling applications.
The most common material used for end mills is tungsten carbide, but HSS (high speed steel) and Cobalt (high speed steel with cobalt as an alloy) are also available.

What is aluminum high-speed steel (HSS-Al)?2021-09-28T06:55:28+00:00

Aluminum-containing high-speed steel (HSS-Al) is smelted by a method of carbon (Al) elements based on molybdenum high-speed steel and is designed to increase thermal hardness and wear resistance.

The performance of the aluminum-containing high-speed steel is similar to the cobalt-containing ultra-hard high-speed steel, the hardness of the heat treatment is HRC67 ~ 69, the anti-bending strength is 290 kg / square millimeters, the impact value is 2.3~3kg 1m/cm² The high-temperature hardness at 600°C is HRC54~55.

Aluminum-containing high-speed steel (HSS-Al) forging performance and excellent cutting performance, but grinding performance is lower than normal high-speed steel when grinding with white jade wheels, and superior to high-speed steel and high vanadium high-speed steel and high vanadium Cobalt high-speed steel.

The durability of the HSS-Al tool is similar to the cobalt-containing ultra-hard high-speed steel, 1 to 2 times higher than the ordinary high-speed steel, up to 3 to 4 times.
