How to choose carbide inserts for different metal parts

Carbide Inserts For Difficult Materials

The tools cutting industry has drastically changed, and these changes can be seen in inserts for Milling and turning the inappropriate materials. This section highlights that how carbide inserts change the inappropriate materials. Tungsten carbide inserts are extremely helpful in different industries,  why are tungsten carbide inserts so excellent?
Carbide inserts are efficient and cost effective compared to other similar tools. Tungsten carbide material is super micro and stuff in a much longer working life. It actually comes in over a dozen different grades, which can all be used for various applications.
CNC profile company produce a much better surface finish quality when used carbide inserts as cutting tools, additionally, carbide recycling materials like tungsten carbide inserts have so many uses, making these materials an essential part for many businesses.
Choosing Carbide Insert Grades
Primarily, the insert grade is usually determined based on the following;
Component material
Method of operation (Finishing, semi-finish, roughing)
Machining conditions include stable, average, or difficult.
Technically, the tool geometry and grade accompany each other.
For example, toughness of a grade can enhance for lower strength in a carbide insert geometry.

Aluminium ,Copper, Non-ferrous Material

Aluminium , copper and other non-ferrous metal removal rates are as high as eight to ten times faster than machining steel.
 It is hard to machine very smooth surfaces on these material, so polishing becomes a critical operation in the final process.
Machining aluminium requires C2 carbide grade inserts for rough and C3 grade for finishing. Only general grade carbide inserts grades with a medium grain with excellent wear resistance for roughing and finishing applications where sharp tips are required. 
Surgical Tools
So many medical professionals rely on accurate and durable tools for all kinds of medical procedures and tungsten carbide is one of the most popular. Surgical tools are one of the most notable uses for carbide. Although the base of the tool itself is typically crafted with titanium or stainless steel, the tip of the tool’s blade or the end of the utensil is made from tungsten carbide.
 
Jewelry
For both jewelry shaping and the jewelry itself, tungsten carbide is a great material for jewelers across the globe. Because tungsten falls just behind diamonds on the Moh’s hardness scale, it’s a great material for wedding rings and other pieces of jewelry. Additionally, jewelers need to rely on efficient tools to work on these pieces and tungsten carbide is great for that. Tungsten jewelry looks nice, is extremely hard, and is often more cost effective than gold — what’s not to like?
Nuclear Science
Tungsten carbide is also used as an effective neutron reflector. This strong material has also been used during early investigations into nuclear chain reactions, specifically for weapons protection. Although this industry doesn’t use tungsten material as much as perhaps some of the others, it’s imperative that everyone handling any materials do so as delicately as possible.
 
 
Feature of the inserts:
 Clearances is also referred to as relief angle value.
These angles are the difference from 90° measured in a plane normal to cutting edge derived from angle between flank and insert’s top surface.
Many carbide inserts have drafted faces on the walls.
Even so, good chip-breaker clear prevents carbide inserts walls from rubbing against the part that will give inferior machining.
The insert with zero clearance angle is usually used for rough machining.
ANSI B212.12-1991 standard describes nine relief angles, all denoted by capital letters. However, one more capital O was added on ANSI  B212.4-2002 standard.
Types denotes other relief angles for new designs of changeable inserts.
This element is denoted by a capital letter showing the differences in design of the carbide insert.
Some of these differences include countersinks, existence of fixing holes, and special features on rake surfaces. Size is the numeric value describing the cutting edge length of the carbide insert,it is denoted by a one or two-digit number, which indicates the value of inscribed circle.
This position also designates the number of eighths of an inch in the I.C nominal size. On rectangular and parallelogram length and width dimensions, thickness is the data, which describes the thickness of the insert.
It is the sixth position with a significant one or two-digit number denoting the number of sixteenths of an inch thickness of carbide insert.
However, it can be a one-digit number when the number of sixteenths of an inch in the thickness is a whole number.
All the dimension should match certain holders, the important feature is that we should check what holder used for the the inserts
Choosing the right carbide insert is not an easy work, but if you keep all the key point parameters in mind, this process can be easy and convenient. Always choose a carbide insert according to your use, whether for Milling, turning or any other industry.
