Do You Know the Advantages and Maintenance Methods of S-Type Milling Inserts?

First, let's understand what the letters on the milling cutter mean. The letters on the milling insert represent its performance and purpose, which usually include the following aspects. The first letter represents the material. H: high-speed steel; C: cemented carbide; S: solid carbide; K: ceramic.

The second letter represents the surface treatment. N: uncoated; T: coated; P: multi-layer coating; The third letter represents the purpose. M: milling; F: fine milling; S: drilling, punching; E: reamer, tapping; R: grooving; D: turning;

The advantages of S-type milling inserts mainly include the following aspects:

‌Good chip removal effect‌: The groove design of S-type milling inserts is conducive to chip removal, especially in the processing of high-viscosity materials, such as aluminum, titanium alloy, etc., which can ensure smooth chip removal and reduce the risk of tool clogging‌.

‌High processing quality‌: S-type milling inserts produce smooth and burr-free chips during processing, which can improve the surface quality and precision of the processed parts.

‌Wide application‌: This milling insert is suitable for processing a variety of materials, including ordinary steel, hardened steel, copper, aluminum, stainless steel, titanium alloy and other difficult-to-process materials, especially in deep groove processing of highly viscous materials.

‌Long service life‌: The design of S-type milling inserts reduces the friction between the front and rear blades, prolongs the service life of the tool and reduces the processing cost.

‌High processing efficiency‌: Due to its superior chip removal performance and smooth cutting surface, S-type milling inserts perform well in high-speed milling and can significantly improve processing efficiency.

S-type milling inserts have the best edge strength. With anti-micro-chipping performance, it can ensure consistent surface quality.

‌Precautions for using S-type milling inserts‌: Cutting parameter selection‌: Select appropriate cutting parameters to avoid tool damage caused by improper cutting process selection or machine tool accuracy problems. Coolant usage: Use coolant reasonably during the processing to ensure that the temperature of the tool and workpiece is controlled within a reasonable range, extend the tool life and improve the processing quality.
