PCD Microdrills and Integral Milling Tools for Machining Silicon Materials
 
Hole machining is a critical process in the field of manufacturing. This process is often challenging due to the semi-closed cutting environment, chip removal issues, heat transfer difficulties, short tool life, and defects such as cracks, burrs, and poor surface finish. These challenges are amplified when working with high-hardness, high-wear-resistance materials like quartz, monocrystalline silicon, polysilicon, ceramics, and titanium alloys, especially for micro holes with diameters ranging from Φ 0.1 to Φ 3 mm. The design and material of the tools used for hole machining, particularly micro-hole machining, are critical indicators of an enterprise's product competitiveness.
 
Addressing Micro-Hole Machining Challenges with PCD Microdrills
 
Industries such as semiconductors, aerospace, 3C, chip manufacturing, and medical equipment require precise micro-hole machining for high-hardness, brittle materials like monocrystalline silicon, quartz glass, zirconia ceramics, and graphite. To meet this demand, Moresuperhard has developed advanced diamond microdrill tools that excel in addressing these challenges.
