About
Jiangsu Gaite Tungsten Technology Co.,Ltd.

As a China Tungsten Carbide Cutting Blade Manufacturers and OEM/ODM Tungsten Carbide Cutting Blade suppliers, established in 1990, the company is located in the southern suburb of Changzhou CityJiangsu Province, with the Yancheng historical site in its east, Xitaihu Lake in its west, No. 312 National Highway in its north and Yanjiang Highway in its south. Early this century, the company expanded its product line and started its cemented carbide road through the introduction of technical personnel and purchasing a batch of advanced production equipment from The origin of cemented carbide. After these years' accumulation, the products have covered ball teeth, brazing sheets, all kinds of blades, molds, and other special-shaped products to offer high-quality products and services to national and foreign customers. in 2009, the company purchased advanced low-pressure sintering furnaces, advanced TPA presses, and other equipment to improve our product's quantity and quality and start a new round of struggle.
In the meantime, our company can manufacture and design cutters and establish a comprehensive set of quality production management systems by buying the advanced equipment from Germany Walter, a five-axis ganged tool grinder from Australasia ANCA, digital tool settings from Sweden, and other processing apparatus, as well as attract high-quality technical and management personnel with rich production experience. And we also pass the lS09001 ,1S014000 and so on. Our company sets up comprehensive cooperative and supplying relationships with many large machinery enterprises and engine enterprises nationwide; high-precision carbide drill, expanding cutters, reamers, and other processing tools that are manufactured according to German Walter's standard production system not only solves the production needs of these enterprises but also can replace necessary tools for imported equipment to lower processing costs for customers.
"Gaite" focuses on shaping corporation culture,people-oriented, integrity management. And all the workers insist on developing themselves with the company.
Gaite people will always keep going forward to cooperate sincerely with friends of all circles and seek common development by relying on products, a sincere attitude, and comprehensive services!

Tungsten Carbide Cutting Blade Industry knowledge

How tungsten carbide cutting blades extend life?

Exceptional Hardness:
Tungsten carbide is a composite material made up of tungsten and carbide, known for their extreme hardness. This hardness is measured on the Mohs scale, with diamond being the hardest at 10 and tungsten carbide typically around 9.5. In comparison, steel typically falls around 5-6 on the Mohs scale.
This exceptional hardness makes tungsten carbide blades highly resistant to wear and tear, particularly when cutting through abrasive materials. As the blade encounters the material, the hard tungsten carbide teeth maintain their sharpness and edge geometry, rather than deforming or chipping like softer steel blades.

Reduced Edge Wear:
The superior hardness of tungsten carbide directly translates to reduced edge wear. As the blade cuts through the material, the hard carbide teeth glide through rather than grinding or scraping, minimizing the wear and tear on the cutting edge. This slow erosion of the edge allows the blade to stay sharp for significantly longer periods compared to steel blades.

Retention of Edge Sharpness:
The ability of tungsten carbide cutting blade to retain their edge sharpness over time is crucial for their extended lifespan. A sharp edge ensures clean, precise cuts and reduces the force required to cut through the material. As the blade dulls, it becomes more difficult to cut cleanly, leading to increased effort, potential material damage, and premature blade wear.
Tungsten carbide's exceptional hardness and edge retention allow it to maintain sharpness for extended periods, even when cutting through tough materials. This means fewer blade changes, reduced downtime, and overall lower costs associated with blade replacement.

Increased Cutting Efficiency:
The sharp and durable edges of tungsten carbide blades contribute to increased cutting efficiency. As the blade glides through the material with minimal resistance, it requires less force from the user or the tool, leading to faster and more efficient cutting. This efficiency translates to reduced cutting time, improved productivity, and less fatigue for the user.

Reduced Breakage:
Tungsten carbide's high toughness, in addition to its hardness, makes it less susceptible to breakage compared to steel blades. When cutting through hard or abrasive materials, steel blades may be more prone to chipping or breaking, especially if excessive force is applied. Tungsten carbide's ability to withstand impact and shock loads reduces the risk of breakage, further extending the blade's lifespan.

Overall Cost Savings:
While the initial cost of tungsten carbide blades may be higher than steel blades, the long-term savings often outweigh the upfront investment. Due to their extended lifespan, reduced downtime, and improved cutting efficiency, tungsten carbide blades can significantly lower the overall cost per cut. The reduced need for frequent blade replacements and the associated downtime contribute to these cost savings.

Why do tungsten carbide blades generate more heat than steel blades during cutting?

Tungsten carbide blades don't necessarily generate more heat  than steel blades during cutting, but they can contribute to a situation where more heat is generated in the overall cutting process. 
Here's why:
Friction: All cutting generates heat due to friction between the blade and the material being cut. This is true for both tungsten carbide and steel blades.
Cutting Mechanism: Tungsten carbide cutting blades often rely on a shearing action to cut through materials. This can be a more efficient cutting method compared to the scraping action of some steel blades. However, shearing can still generate friction and heat.
Dullness: A dull blade, regardless of material, creates more friction and therefore more heat during cutting. Tungsten carbide blades may hold their edge longer, but a dull carbide blade can still generate significant heat.

Factors Affecting Overall Heat Generation:
Cutting Speed: Faster cutting speeds generally create more heat due to increased friction.
Material Properties: Denser or harder materials require more force to cut, leading to increased friction and heat generation.
Lubrication: Using a lubricant can reduce friction and heat during cutting, regardless of the blade material.
