Deep hole processing of metals and plastics (such as acrylic). We have various sizes available, so please feel free to consult with us.
This is an introduction to deep hole machining (gun drilling). In metals, deep hole machining is often required for cooling water flow paths, air passages such as pneumatic lines, and heater insertion holes. Our company processes deep holes ranging from φ3 to φ30 using gun drilling, providing finished products. Some customers may also request deep hole machining in plastic. Depending on the material and hole size, we may be able to accommodate such requests, so please feel free to consult with us. We have attached a catalog (PDF) with information on hole sizes and machining lengths.
