The tools used during machining determine the quality of the finished goods and the productivity of the workers. Iscar provides tooling solutions for various applications to ensure that companies improve the efficiency of their processes. Carbide inserts are some of the range of products that the metalworking enterprise carries to cater to its diverse clientele, including die and mold, automotive, and aerospace sectors, among others.What are coated carbide inserts?
The development of milling tools with multi-functional capabilities has made it possible to use versatile insert styles. Coated inserts are one option that you have when buying Iscar cutting tools. A manufacturer can coat its carbide inserts with compounds titanium such as carbonitride, aluminum oxide, and zirconium carbonitride. The compounds can be used individually, or a manufacturer can opt to combine them with a chemical, physical, or multi-layer deposition process, which allows for more layers. The benefits of coating an indexable insert are:
- The extra layer of ceramic hardness the insert will improve is cutting ability. This fast action increases the milling speeds and production because you can do more.
- The wear-resistance property of these coatings is their biggest advantage because it improves tool life. For one, the coating reduces the temperature levels during cutting, which decreases the rate of wear of the tool. The coating also protects the insert substrate from abrasion and corrosion.
- Coated carbide inserts have a wider range of applications than uncoated carbide, and that makes them suitable tools for many machining tasks.
The grade of the carbide is a critical element when choosing an insert for a cutting process. Iscar uses a coating and post-coating treatment to create the carbide grade. The cemented carbide is the staple ingredient, and it consists of hard carbide particles that are bound using a metal, in most cases cobalt. The international standard ISO 513 is used to categorize hard cutting materials according to their applicability, and Iscar employs the same standard for its grades.
Products are marked with ISO 513 followed by several numbers and letters that indicate the engineering material that can be cut using a tool made from that grade. These classification numbers are based on an estimated scale to tell ratio of carbide hardness to toughness. Therefore, the higher the number, the tougher the grade; the lower the number, the harder it is.What are the considerations when buying Iscar carbide inserts?
Given the numerous alternatives that Iscar offers, selecting the right carbide indexable insert can be a complex process. A few guidelines are critical:
- Be clear about the metal cutting operation that the product will be used for. Iscar makes specific insert grades for milling, drilling, and turning, among other tasks.
- Identify the material to be machined. The classification of a carbide indexable insert grade determines to which material it can be applied. The tooling solution you get for hardened steel is not the same as for aluminum or brass.
- The type of machine tool will tell you which carbide inserts are appropriate. Various machines have different tool holders, capabilities, and specifications, which determines the suitability of an insert.
