Customized Deep-Hole Drilling

SUHNER GROUP’s SOMEX unit offers custom made deep-hole drilling operations capable of drilling up to 12-mm diamters and as deep as 100x the diameter. These modules can be integrated directly into transfer machines, special purpose machines or conventional machines, such as turning machines.

In addition to standard MAX machining units, SOMEX offers peripheral components. Thanks to its modular component concept, SOMEX can provide customized turnkey, small and economical deep hole drilling machines.

The unique SOMEX design concept combines the guide bushing with a chip basket, allowing both items to travel in unison. The movement of the guide bushing is air-driven, which helps to provide much closer contact to the part while preventing the escape of the coolant medium. For longer deep-hole drilling applications, it may be necessary to integrate a support bushing to stabilize the deep hole drilling tool.

The degree of accuracy in a deep-hole drilling application measured in the deviation from the theoretical part centerline is greatly enhanced by a slow part rotation in a counter-clockwise direction.

For deep-hole drilling applications above 18-mm diameters, SOMEX has the option to equip its MAX machining units with drilling systems from BTA or EJEKTOR lines. In these applications, the coolant and chip management is accomplished through the spindle center. The emulsion is collected at the backend of the spindle, filtered, and pressurized to re-enter the coolant system. This solution is often used in high-volume precision parts manufacturing such as automotive and other industries. Learn more at www.suhner.com
