Introduction of Gundrilling Machine
Gundrilling, also known as deep hole drilling, is a process that produces deep, straight holes in a variety of materials. Holes depth-to-diameter ratio deeper than 20:1 generally require a dedicated gundrilling machine to achieve highest productivity and process reliability. The size, concentricity, surface roughness can be maintained precisely.
Features
The machine is suitable for molds, waterlines, heat and ejector pin holes, heat exchanger, hydraulic manifold, shafts and machine parts.
Machine base made by FC30 high strength cast iron
The removal of iron chips is designed to drop directly, which prevents block in the path
CNC controller can be either FANUC or MITSUBISHI.
Auto lubrication system.
Special custom-made requirements are welcomed
