Processing hardness and characteristics of different tools Serial number 1 2 3 4 5 Tool type Carbide tool Coated carbide tool ceramic knife CBN cubic boron nitride cutter PCBN polycrystalline cubic boron nitride Processing hardness HRC 40 40~50 45~55 50~60 60~68 Characteristics High flexural strength and impact toughness, Increased hardness and wear resistance for high speed turning High hardness, high strength, good wear resistance, Good chemical stability and low friction coefficient And low in price, suitable for processing hardened steel And hardened cast iron Heat resistance and chemical stability are slightly poor, However, the impact strength and crush resistance are good. Suitable for processing hardened steel, High hardness, good wear resistance, high compressive strength and good impact toughness, suitable for Metal processing online noun explanation: HRC Rockwellhardness, which was proposed by SPRockwell in 1921, is the hardness of a metal material measured using a Rockwell hardness tester. This value has no unit and is only represented by the code "HR". There are three different standards for A, B, and C in HRA, HRB, and HRC in Rockwell hardness. It is called scale A, scale B, and scale C. HRC is a hardness obtained with a 150Kg load and a diamond cone indenter for materials with high hardness. For example: hardened steel, etc.
High Speed self-Recovery Rapid doors are the technological evolution of old, PVC high speed doors or heavy folding doors, now obsolete and not suited to today's industrial needs.
High-quality panels, the resistive safety edge fitted to the bottom edge of the door, photocells and barriers make this product both safe and durable, being totally self-repairing, thanks to its special [Anti Crash System".
This door designed with a perimeter structure in galvanized or stainless steel, which is ideal for sliding panels. The door panel rides effortlessly within a track, thanks to the special profile and hinge designed by us, requiring low maintenance. The panel is rolled up on a roller placed within the upper crossbeam.
The door can be equipped with a counterweight or ups batteries, to fully open the door in case of power failure, and can also be equipped with large transparent sections to create a brighter and safer working environment.
Self-Repairing Door Curtain made of reinforced PVC, with flexible weighted soft bottom edge.
The edge of curtain has continuous injection molded teeth that then move up and down in a self-lubricating polyethylene track attached to structural galvanized side frames.

Processing hardness and characteristics of various tools
Metal processing online tips: Different types of tools should be selected for different materials to be processed to meet different processing hardness requirements. This will not cause the cutting tool to be damaged due to the "unreachable force", nor will it cause the waste of "anti-aircraft guns to fight mosquitoes". The following are the hardness and characteristics of different tools.
