Diamond Grinding Wheel for PCB Micro Tools Precision Grinding

PCB micro drill

There are many products have an extremely high demand for drilling micro holes , such as fuel injection nozzles, cameras, mobile phones, medical instruments, micro dies and molds, computers, watches, bearings, especially printed circuit boards (PCB). So micro drill bit with higher accuracy，the flute of drill plays a significant role in its cutting performance.

PCB micro drill are used primarily in CNC machines for drilling small precision holes for printed circuit boards, medical and aerospace,etc industries.

Application of diamond grinding wheel for micro drills grinding
PCB micro dril grinding wheel is mainly used for small diameter tungsten, stainless steel or hss drills, micro drills, and end mills used in electronics, medical technology, and the automotive industry.
Processing objects: solid carbide, stainless steel welding type PCB processing micro-milling cutters, drills grinding.

* Moresuperhard can provide diamond tools for PCB micro drill such as diamond cut off wheel (for cutting bar material),cylindrical grinding bar(rough grinding wheel), peel grinding wheel and diamond fluting wheel for slotting PCB micro drill.

PCB micro drill manufacture process:                                

1. Cut off of Bar
2. First step:Rough grinding
3. Second step: Peel grinding
