Hydraulic chucks are an excellent choice for high accuracy applications due to their ability to maintain runout accuracy over an extended period of time.
Cleanliness is key to achieving good runout control when assembling tool holders. Small particles or oil in a tool holder can cause large runout of the cutting tool, deceasing tool life and performance.
Coated carbide micro deep hole drills manufactured by SPHINX Tools can reliably create wire EDM starter holes up to 5x faster than traditional wire erosion techniques.
