CNC 6-Axis Drilling & Machining | Deep-Hole Drilling Capabilities

Deep-hole drilling is a complex process that describes holes drilled with a high rate of metal removal and extremely close accuracy. A hole deeper than ten times its diameter is considered a “deep hole” and requires a specialized drilling technique. Venango’s CNC drilling equipment includes standard deep-hole drilling machines and tools capable of a specialized deep-hole drilling called gun drilling. Customers are encouraged to take advantage of our large 87” by 79” CNC 6-Axis Drilling and Machining Center, capable of reaching a 78.74” drilling depth with a 2.36 maximum diameter. These unique deep-hole drilling machines also feature a 30-position automatic tool changer and can assist with counterboring, tapping, and milling. In addition to the above capabilities, Venango Machine Company can also offer our customers the following:

Tight hole diameter tolerance
High-quality surface finish (depending on the material hardness)
Complex drilling operations performed without secondary operations on our state of the art deep-hole drilling machines
Long lengths of stock can be drilled and then cut into individual pieces

For specialized deep-hole drilling, Venango is proud to offer our gun drilling services. Using a single-flute tool, we are able to drill highly accurate, straight, deep holes.

Gun Drilling vs. Deep-Hole Drilling

A deep hole drilling machine is a metal-cutting machine tool designed to produce deep and precise holes. Venango’s deep-hole drilling equipment is engineered to optimize all aspects of the drilling process and drill deep holes with accuracy, reliability, and efficiency. Our dedicated deep-hole drilling machines provide tooling support, coolant delivery, and process feedback for customers and machinists alike. Venango’s experts ensure that our deep-hole drilling machines are optimized to reduce cycle time, stabilize tooling, and prevent tool breakage and process failures. Two tooling types are generally used to produce deep precision holes: gun drilling and STS drilling.

STS drilling🌃 (Single Tube System, also known as BTA drilling) is possible for holes 20 mm [0.80 in] to 250mm [10 in] in diameter and larger. STS drilling uses external coolant flow and internal chip removal.

Gun drillsꦜ differ from conventional drills by having a single straight flute cutting edge and a single internal coolant hole; this method was invented for drilling the barrels of guns, which famously require extremely straight, precise barrel bores. These drills are typically used for fine deep holes from 1mm [0.040] to 50mm [2.00 in] in diameter.
