class=\"wp-block-heading\">Why Quartz Glass Drilling Is Challenging<\/h2>\n\n\n\n<p>Unlike metals or plastics, quartz behaves differently under machining forces.<\/p>\n\n\n\n<p>Key material characteristics include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>High hardness<\/li>\n\n\n\n<li>Brittle fracture behavior<\/li>\n\n\n\n<li>Niska rozszerzalno\u015b\u0107

become more pronounced:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Edge chipping<\/li>\n\n\n\n<li>Micro-cracks<\/li>\n\n\n\n<li>Surface defects<\/li>\n\n\n\n<li>Thermal damage<\/li>\n\n\n\n<li>Poor dimensional consistency<\/li>\n<\/ul>\n\n\n\n<p>These defects can affect optical performance, contamination control, and component lifetime.<\/p>\n\n\n\n<p>This is why selecting the appropriate drilling process becomes critical.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Two Main Technologies Used for Quartz Hole Drilling<\/h2>\n\n\n\n<p>For custom quartz fabrication, two common methods dominate:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CNC mechanical drilling<\/li>\n\n\n\n<li>Wiercenie laserowe<\/li>\n<\/ul>\n\n\n\n<p>Each technology offers unique advantages and limitations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">CNC Drilling for Quartz Glass<\/h2>\n\n\n\n<p>CNC drilling uses precision machine tools equipped with diamond-coated tools or specialized abrasive processes.<\/p>\n\n\n\n<p>Material removal occurs through controlled mechanical contact.<\/p>\n\n\n\n<p>Typical capabilities:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table

applications, hole diameters below approximately 0.5 mm become increasingly difficult.<\/p>\n\n\n\n<p>Actual capability depends on thickness and geometry.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Laser Drilling for Quartz Glass<\/h2>\n\n\n\n<p>Laser drilling removes material using concentrated thermal energy.<\/p>\n\n\n\n<p>Instead of direct mechanical contact, the

class=\"wp-block-heading\">Material Thickness<\/h3>\n\n\n\n<p>As thickness increases, maintaining straightness becomes more difficult.<\/p>\n\n\n\n<p>Example:<\/p>\n\n\n\n<figure
