Technology and R&D Capabilities

The main drafter of three national and industry standards, including “Extra coarse grain cemented carbide tips for engineering” also holds over 20 technical patents, including three invention patents.

Industry standards lead the way

Xinda Machinery is the drafting unit for national and industry standards such as “Cutting Picks for Tunneling” and “Extra coarse grain cemented carbide tips for engineering” As a technological benchmark in China’s high-end cutting pick manufacturing sector, Xinda consistently sets stringent quality standards. Its products fully match the performance of world-class international brands and have successfully achieved domestic substitution in fields including hard-rock tunneling, coal mining, tunnel construction, and open-pit mining.

Core Process Breakthroughs

Focusing on the three core objectives of high toughness, high wear resistance, and high stability, Xinda continues to advance key materials and manufacturing processes:

Ultra-coarse-grain cemented carbide tips: Industry-leading impact resistance and fracture toughness;
High-strength steel body: Enhanced overall structural strength through combined heat treatment and precision forging;
Ultra wear-resistant protective layer (national patented): Effectively reduces wear of both carbide and steel body, significantly extending service life.

These innovations ensure stable performance, longer tool life, and reduced replacement frequency in UCS80-120MPa hard-rock conditions.

Research Collaboration Platform

Xinda is collaborating in depth with top domestic research institutions such as China Iron and Steel Research Institute Group to establish a joint innovation experimental platform, focusing on research into high-performance cemented carbide materials, advanced welding processes, heat treatment control, and failure mechanisms.

Through industry-academia-research collaboration, Xinda rapidly transforms laboratory technological achievements into mass-production capabilities, continuously advancing the localization of high-end engineering equipment components made in China.

Continuous innovation-driven

Xinda Machinery has accumulated numerous national patents and has established a dual-driven model of “R&D + Manufacturing,” seamlessly integrating the entire value chain—from materials design and process development to on-site application.
We remain committed to driving development through innovation, continuously exploring high-toughness and high-wear-resistant material systems, and striving to become a leading global brand in high-end cutting picks for the mining and tunneling industries.
