In April 2025, LINKUT established the Solid PCD Micro - cutting Tool Project Department. This move fills the gap in the industry for miniaturized and high - precision PCD cutting tools, marking the advancement of China's super - hard cutting tool technology towards "nanoscale precision" and "serialized applications". Currently, Solid PCD Thread milling cutter，Solid PCD Corner end mill ，Solid PCD  Micro Drill developed by the project department have been launched in batches and have been recognized by the market.

Technological Breakthroughs: Transcending Tradition and Building a Product Series

Relying on 12 years of experience in super - hard cutting tool manufacturing, the project department addressed the pain points of traditional cutting tools such as "limited specifications, insufficient precision, and short lifespan". Taking the R & D path of "material - process - application", it broke through the bottleneck of welding processes and formed a product matrix for multiple scenarios:

1）Solid  PCD Micro - edge Milling Cutter: With integrated molding, the number of cutting edges has increased by 3 times, and the strength has increased by over 40%.

2）Solid  PCD Thread Milling Cutter: Featuring a helical cutting edge and high - precision grinding, the processing efficiency has increased by 50%, and the qualified rate is over 99.8%.

3）Solid  PCD Drill Bit: By optimizing the chip - evacuation groove and crystal grain arrangement, its lifespan is 8 - 12 times that of traditional carbide drill bits, and it is suitable for micro - hole processing from 0.1mm to 5mm.

Quality Control: Ensuring the Whole Process and Winning Customer Praise

LINKUT has established a three - level quality control system for "raw materials - processing - finished products":

1）Raw Materials: Imported high - quality PCD is selected and tested against 12 indicators.

2）Processing: Five - axis equipment and on - line laser measurement are used to control the error within ±0.001mm.

3）Finished Products: 100% inspection is carried out, and SEM (Scanning Electron Microscope) and coordinate measuring machines are used to ensure nanoscale precision.
