Deep hole drilling machine is widely used in military, aerospace, oil and coal, automobile, mold, metallurgy, water conservancy and other industries of large, medium and small deep hole processing. Through once continuous drilling, it could achieve the guaranteed processing accuracy and surface roughness usually processed by drilling, expanding and reaming.2.

Machine processing accuracy
Hole diameter accuracy: IT7-IT10 (good conditions IT7-IT8; general conditions IT9-IT10)
Surface roughness: Ra 0.4-3.2μm (relate to specific material, through the special order of the tool to achieve a better surface roughness)
Hole Centerline decline:
A: 0.5mm/1000mm (workpiece rotates, length to diameter ratio is within 100: 1, even material, reasonable feed)
B: 1mm / 1000mm (workpiece rotates, length to diameter ratio is within 100: 1, even material, reasonable feed)
