Product Application:
Tungsten carbide burr is used widely in the shipping construction,
auto engine porting and foundry fabrication. With its high rotating
speed and hardness, it can machine a lot of different materials
like cast iron, carbon steel, alloy steel and non ferrous material.
High life service of product is warranted for virgin and excellent
raw material which is one of most critical factors to the tools'
life.
Company Profile
Joint carbide co.,ltd was established on January 21, 2019, as a sales branch established
by Zigong joint carbide co.,ltd in Chengdu.Our company covers
20,000 square meters was a high-tech enterprise integrating
research, development, production and sales of cemented carbide
products and cemented carbide rotary burrs,carbide tire
studs,carbide repair tire stud,carbide particles & composite
welding rods.

The company is committed to providing high-precision, high-speed
and efficient metal grinding solutions and services for the
machinery manufacturing industry. The company introduced the most
advanced international five-axis five-linkage CNC tool grinder,
three-coordinate tool detector and other equipment from Germany.
The aim is to produce high-quality, internationally competitive
products using internationally advanced equipment. At present, our
company has become the largest rotary file production base in the
country, with a mature R&D team and management team in China,
and a stable supply chain.

As a metal cutting tool, the rotary file has been exported to
Europe, North America, South America and a small number of
Southeast Asian countries.A few days ago, the company has completed
the accumulation of various infrastructure and technology research
and development. Since 2020, our company has added 200 five-axis
and five-linkage rotary grinders. By 2023, our company will invest
a total of 400 five-axis and five-linkage rotary grinders. Grinding
machine (total value 150 million yuan). By then, our company will
become the world's largest supply base for rotary files.We have the
world's advanced raw material cemented carbide formula technology,
the most optimized advanced manufacturing process, and the
largest-scale production equipment.
