MATERIAL SELECTION
Different customers cut different materials. Even for the same customer, different materials are often cut on the same slitting machine. In this way, there are different requirements for the wear resistance and sharpness of the slitter knife. And the material itself is not omnipotent. Often, materials with good wear resistance and sharpness have poor impact resistance, and materials with good impact resistance have poor wear resistance and sharpness. Therefore, different blade materials should be chosen for different cutting materials.

TOLERANCE SELECTION
Flatness and Parallelism
Sufficiently high flatness and parallelism are necessary conditions to ensure that the shear clearance between the upper and lower slitter blades of the slitting machine is always consistent during dynamic operation. Correct clearance is at the heart of ensuring precision cutting. If the surfaces of circular slitter knives are not flat, or the two sides of the blade are not parallel, the gap between the upper and lower blades is always changing. In addition, the reaction force generated by the extrusion of the strip during slitting also causes the gap to change continuously. This will make it impossible to get burr-free strips.
Thickness Tolerance
The thickness tolerance of the blade is mainly to ensure the cutting accuracy of the width of the metal strip and prevent the cumulative error in the knife assembly. If a blade with a thickness tolerance of 1~2 μm or even 0.5 μm cannot be provided, the cumulative error when multiple shearing knives are assembled is unavoidable.
Surface Roughness
A good surface roughness of the slitter knife surface can improve the rigidity of the entire shearing system, increase the sharpness of the blade, reduce micro cracks on the blade and prolong the life of the blade. Different machining processes can result in different surface finishes. For high-precision non-ferrous metal processing, it is generally necessary to choose 0.05 - 0.1 μm. For slitting other thin coils, a surface roughness of 0.1 - 0.2 μm can be chosen.
OUTSTANDING PERFORMANCES
Depending on your budget and requirements, our team of experts will develop a customized solution for you, including but not limited to the selection of slitting tool materials, accuracy, etc. If necessary, our field team will come to your company to study the current cutting problems and improve your cutting quality.
INCREASED LIFESPAN & COST SAVEINGS
By selecting the right raw material for the slitter knife and combining it with proven heat treatment processes, we can produce knives that will last significantly longer and thus reduce your tool purchase costs.
PRECISE STRIP WIDTH CONTROL
Ultra-high precision slitting tools help you achieve perfect strip width control. The application of "+", "0" and "-" marks further improves the cutting accuracy.
width of the 2nd strip 27.95 mm
width of the 6th strip 27.95 mm
width of the 9th strip 27.95 mm
EDGE QUALITY CONTROL
Suitable raw materials for tools and advanced production processes ensure continuous sharpness of the slitter knives. Ultra-high precision slitting tooling ensures dynamic and stable upper and lower knives clearance.
QUALITY ASSURANCE
SGS AUTHORITATIVE TESTING
Goodklife has always been committed to providing high-quality, ultra-high-precision cutting tools to customers around the world. In order to enhance mutual trust, for the first cooperation, we now provide free SGS testing services to invited customers to dispel all your doubts.
MATERIAL QUALITY ASSURANCE
Raw material is the foundation of knife quality. Goodklife has the most complete range of blade raw materials in the world. We will recommend the most suitable blade material according to the customer's detailed cutting conditions to ensure that the blade is lastingly sharp without chipping. In order to meet the growing demand for high-strength steel shearing, Goodklife has also developed the national patented material G1, which greatly improves the shearing effect.
At present, the vast majority of knives on the market are made of raw materials smelted by conventional techniques. In order to further improve the quality of the raw materials for the knives, Goodklife only selects raw materials produced by the ESR process. The ESR process is a further purification of raw materials after the conventional steelmaking process.
Compared with raw materials smelted by conventional methods, ESR raw materials can largely avoid the phenomenon of chipping, and can also significantly improve the service life of the blade.
HEAT TREATMENT ASSURANCE
Goodklife's heat treatment workshop is fully equipped with various heating, annealing, quenching and tempering equipment, and is equipped with a number of experienced professional senior engineers. After years of experience summarization, the company's unique heat treatment process has been formed. Blades with a thickness of less than 100 mm can be fully hardened into the core, which can ensure that the performance of the blade is the same until it is ground to the minimum size. Not only the safety factor of the blade is high, but also the production efficiency can be significantly improved and the cutting cost can be reduced.
PRECISION TOLERANCE ASSURANCE
Goodklife ultra-high precision slitting knives are more like works of art. The company currently has a number of ultra fine grinding machines and lapping machines. Every employee in the finishing workshop is deeply rooted in the pursuit of high precision, and strictly abides by the operating system to ensure that every slitting tool is qualified.
