II. Core Application Domains of Specialized Hard Coating Deposition Equipment for Small Tools

The application scenarios of specialized hard coating deposition equipment for small tools focus on the processing fields that require high precision and high wear resistance. The core application directions are as follows:

• 1. Electronic Information Industry: Coating for PCB Micro Drills and Milling Tools

  It is the core equipment for the PCB (Printed Circuit Board) industry, used for TiN, TiCN, TiAlN coating deposition of 0.1~0.5 mm ultra-fine PCB micro drills and slot milling tools. The lifespan of the coated micro drills can be increased by 3~5 times, solving the problems of "drill breakage and knife sticking" in PCB board processing, and meeting the processing requirements of high-density circuit boards.

  It can also be used for coating of semiconductor packaging tools (such as sawing tools, cutting tools), improving the cutting performance of the tools on silicon wafers and ceramic substrates.

• 2. Precision Processing Industry: Coating of Numerical Control Micro Tools

  For micro turning tools, ball-end milling tools, and engraving tools (diameter 1~10 mm) used in mold processing and precision part processing, coating is carried out. The coating types are mostly TiAlN and AlCrN, which can increase the cutting speed by 20%~40% and the lifespan by 2~3 times when processing hardened steel (HRC55 and above), stainless steel, and titanium alloys.

  It is suitable for micro processing tools for medical devices and aerospace fields, such as micro milling tools for bone implant processing and polishing tools for aircraft engine blades.

• 3. Dental Medical Industry: Dental Tool Coating

  Used for coating of dental high-speed drill needles, root canal files, etc. The coating materials are mainly TiN (golden yellow) and DLC (like diamond). The TiN coated drill needles have good wear resistance and are conspicuous in color, making it easy for doctors to observe; the DLC coated ones have self-lubricating properties, reducing damage to tooth tissues during dental surgeries.

  The coated dental tools can withstand high-temperature and high-pressure sterilization (134℃, 0.2 MPa), and the coating is not easy to fall off, meeting the hygiene standards of medical equipment.

• 4. Woodworking and Engraving Industry: Precise Engraving Tool Coating

  For small tools such as woodworking engraving tools, acrylic cutting tools, and jade engraving tools, TiN or CrN coatings are deposited to improve the cutting efficiency of the tools on wood, acrylic, and jade, avoiding the wear and dulling of the tool edges, and prolonging the tool lifespan.

• 5. Research and Laboratory Field: Process Research and Testing

  Universities and research institutions' material laboratories often use small equipment to conduct research on new coating materials, such as multi-component alloy coatings and nano-structured coatings. Through small-scale coating deposition testing, the coating performance is tested, and then scaled up for promotion.
