Factory Direct: WNMU Carbide Insert for Shoulder Milling

Shoulder milling cutters are index-able designed with wedge type clamping or screw-on type clamping to achieve high-quality machining. WNMU is one kind of double-sided square shoulder milling insert with sharp cutting edge and small cutting resistance. Thick specification design for stronger collapse resistance. No directional blade, left and right knife can be used; 6 double-sided blades is very economical.Types of Carbide Inserts Carbide inserts come in a large variety suited for different applications. The common types include the following: Turning carbide inserts Threading carbide inserts Grooving carbide inserts Milling carbide inserts Drilling carbide inserts Boring carbide inserts Main Considerations for Selecting Right Carbide Inserts When choosing the correct carbide inserts, there are several parameters you must consider. Ultimately, such factors determine whether you’ll attain good machining performance and chip control for desirable results. Here are the main parameters to have in mind; a)Carbide Insert Geometry Geometries can be divided into three primary styles based on mode of operation. These styles include Roughing – It is high depth of cut and feed rate combinations suitable mostly for operations, which require highest edge security. Medium – Ideal for medium operations to light roughing. Feed rate and wide range of cut depth combinations. Finishing – Suitable for operations at light depths of cut and relatively low feed rates. Fit for operations requiring low cutting forces. b)Carbide Insert Grade Primarily, the insert grade is usually determined based on the following; Component material Method of operation (Finishing, medium, roughing) Machining conditions, i.e., good, average, or difficult. Technically, the tool geometry and grade complement each other. For instance, toughness of a grade can compensate for a lack of strength in a carbide insert geometry. c)Carbide Insert Shape When selecting carbide shape, it is important to ensure it is a relatively required tool entering angle accessibility. Always consider choosing the largest possible nose angle to provide insert and reliability. However, this must be balanced against cuts variation that needs to be performed. Ideally, a large nose angle is sturdy but requires more machine power. Also, it has a higher tendency for vibration. On the other hand, a small nose angle is relatively weak and has small cutting edge engagement. Therefore, it tends to be more sensitive to the varied effects of heat. d)Carbide Insert Size Always select a carbide insert size based on the specific application needs and space for cutting tools in the application. Relatively large insert size provides better stability. Heavy machining requires a carbide insert size of above IC 25mm. When choosing the right size of carbide insert, always determine the largest depth of cut. Consider the cutting length while determining the tool holder entering tool, depth of cut, and machine specification. e)Material to be Machined Carbide inserts are used for machining different types of materials. Thus you must ensure you are choosing the right tool suitable for the specific material. Some of these materials include the following; Aluminum Bronze Hardened tool steel Soft tool steel Stainless steel Cast Iron Non-ferrous metals Heat-resistant alloy. Titanium alloy High hardness materials f)Type of Machine Tool Machine tools used with carbide inserts also come in a large variety. The commonly used ones include the following; Swiss-type, CNC lathe, 5 axis, turning machine, lathe machine, conventional VMC among others.
