If you are machining high-heat-dissipation LED aluminum substrate boards, you surely understand this pain: standard tungsten carbide tools wear out extremely quickly—so much so that frequent tool changes make you question your life choices. Heat buildup during cutting causes thermal deformation of the substrate, resulting in low yield rates. Additionally, excessive burrs and even blackened edges frequently lead to customer rejection during inspection.
Tiansheng Hengzuan CVD Diamond-Coated End Mills, Specifically Designed for “Hard-on-Hard” Machining!
A recently completed customer case study：
Customer:
A large LED module manufacturer.
Challenge:
Continuous drilling of 2.0 mm thick, high-thermal-conductivity aluminum-based substrates.
Our solution:
Replace with TianShengHengDrill’s custom-grade diamond-coated end mills.
Test results are astonishing:
Remarkable tool life: Maintains hardness after 8 hours of continuous cutting—equivalent to 18 conventional tools!
Cool cutting performance: Exceptional thermal conductivity effectively lowers the cutting-zone temperature, eliminating workpiece deformation.
Mirror-smooth edges: Nano-coating minimizes friction, yielding perfectly smooth, mirror-finish cuts—no secondary edge finishing required.
The plant manager ran the numbers: Although each tool costs slightly more, factoring in tool-change labor, scrap rate, and total procurement volume reduces monthly costs by an impressive 38%!
