Granite mechanical components are widely recognized in precision industries for their unmatched stability, hardness, and low thermal expansion. These properties make them essential in applications ranging from CNC machines to semiconductor equipment, coordinate measuring machines, and high-precision optical instruments. However, achieving accurate drilling and grooving in granite presents significant technical challenges due to its extreme hardness and brittleness.
Drilling and grooving granite components require a careful balance between cutting force, tool selection, and process parameters. Conventional methods using standard metal-cutting tools often lead to micro-cracks, chipping, or dimensional errors. To overcome these issues, modern precision manufacturers rely on diamond-coated tools and optimized cutting strategies. Diamond tools, due to their superior hardness, can efficiently cut granite while maintaining edge sharpness and surface integrity. Controlled feed rates, appropriate spindle speeds, and coolant application are critical factors to minimize vibration and thermal effects, ensuring the dimensional accuracy of the drilled holes and grooves.
Equally important is the process setup. Granite components must be firmly supported and precisely aligned during machining to prevent stress concentration and deformation. In high-end facilities, specialized vibration-damping fixtures and CNC-controlled machining centers are employed to achieve micron-level tolerances. Furthermore, advanced inspection techniques, including laser interferometry and coordinate measurement systems, are applied after machining to verify groove depth, hole diameter, and surface flatness. These steps ensure that each component meets stringent industry standards for precision and reliability.
Maintaining the performance of drilled and grooved granite components also involves proper post-machining care. Surfaces should be cleaned of debris, and contact points must be protected from contamination or impacts that could introduce micro-damage. When handled and maintained correctly, granite components retain their mechanical and metrological properties for decades, supporting consistent high-precision performance in demanding industrial environments.
