The small tool-specific hard coating equipment is a vacuum coating
device designed for precision micro-tools (such as PCB
micro-drills, dental tools, CNC micro-milling tools, engraving
tools, etc.). Its core lies in using physical vapor deposition
(PVD) or chemical vapor deposition (CVD) technologies to prepare
hard coatings like TiN, TiCN, TiAlN, and AlCrN on the surface of
the tools, thereby enhancing their hardness, wear resistance,
high-temperature resistance, and service life. 1. Core Features of the Small Tool-specific Hard Coating Equipment - 1.1 Compact cavity design, suitable for the clamping of precision
micro-tools
- 1.2 Fine coating process, meeting the strict performance
requirements of the tools
- 1.3 Efficient vacuum system, ensuring the purity and density of the
coatings
- 1.4 Convenient operation and maintenance, suitable for small-batch
production scenarios
- 1.5 Strong coating adhesion, suitable for the cutting conditions of
the tools
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.
