NEW PRECIHOLE GVN40C

Precihole’s GVN-C Series Gun Drilling Machines with Counter Rotation offer superior hole concentricity as it relates to deep hole drilling for high precision gun barrels. These machines incorporate the latest technology available and can be customized to suit volume requirements and provide excellent straightness, surface finish and bore tolerance. Length to diameter ratios of up to 125 are possible. The Precihole GVN-C series machines are complete solutions that include features needed for continuous and repeatable performance over many years. The gun drilling operation is considered one of the most critical operations in the barrel making process. This process really decides the quality of the finished barrel. Precihole’s GVN-C series barrel machines offer the best combination of output parameters like hole straightness, surface finish and bore tolerance. Having counter rotation in the Precihole GVN-C series is effective for drilling holes of 40:1 depth to diameter ratios or more.
