Quartz glass is the core material for high-performance spray plates in semiconductor and photovoltaic industries, featuring excellent high-temperature resistance, chemical inertness and insulation properties.

However, precision micro-drilling on this ultra-hard brittle material has long been a major industrial bottleneck for precision machining, plagued by two persistent pain points: low machining efficiency and serious hole-edge chipping. These issues severely limit production capacity, lower product yield and raise manufacturing costs, pushing enterprises to seek high-performance PCD cutting tools for targeted solutions.
        

Traditional processing mainly adopts ordinary carbide drills, which are not suitable for precision machining of quartz glass. The insufficient hardness of carbide tools causes rapid wear, forcing low-speed and slow-feed machining that drags down efficiency sharply.

Besides, blunt cutting edges bring excessive cutting force and impact, leading to obvious hole-edge chipping, rough hole walls and hidden micro-cracks. For D0.5*5mm micro-holes, the conventional process takes 270 seconds per hole, with hole-edge chipping up to 0.4mm, resulting in long delivery cycles and high defective losses, highlighting the urgency of upgrading to professional PCD drills.

To break through these precision machining dilemmas, LINKUT launches high-performance solid PCD (Polycrystalline Diamond) drills, a professional PCD cutting tool specially designed for precision drilling of hard-brittle materials like quartz glass. 

Relying on the ultra-high hardness and superior wear resistance of PCD material, these solid PCD drills have sharp and durable cutting edges, which reduce mechanical impact on quartz glass effectively, realizing high-speed precision drilling while ensuring workpiece integrity and machining stability.

Mass production tests show remarkable and credible data: when conducting precision micro-drilling of D0.5*5mm holes on quartz glass spray plates, LINKUT solid PCD drills shorten single-hole processing time from 270 seconds to only 75 seconds, improving machining efficiency by 72%. A single PCD drill can stably machine 1200 holes continuously, avoiding frequent tool changes and enhancing production continuity. 

The finished holes have smooth and burr-free inner walls, with hole-edge chipping reduced from 0.4mm to 0.15mm, cutting chipping defects by 70%, fully meeting the strict precision machining standards of high-end semiconductor and photovoltaic components.

For manufacturers focusing on hard-brittle material precision machining, LINKUT solid PCD drills achieve a triple optimization of efficiency, quality and cost control. This high-end PCD cutting tool not only solves the core pain points of low efficiency and serious chipping in quartz glass spray plate drilling, but also reduces consumable loss and labor costs. 

It helps enterprises realize large-scale high-precision production, making it the preferred choice for precision drilling and high-end manufacturing of quartz glass and other hard-brittle materials.
