Deep Hole Drilling
Deep Hole Drilling
Suhner India Pvt Ltd, Automation Expert, offers Deep Hole Drilling solutions. Investments in conventional deep hole drilling machines can be very expensive. Somex offers custom made deep hole drilling solutions capable for drilling up to Ø12 mm, as deep as 100 x Ø. These modules can be integrated directly into transfer machines, special purpose machines or conventional machines like turning machines. The potential for cost savings is enormous. In recent years, Somex devoted a lot of time and resources to the deep hole drilling technology. In addition to standard Max machining units, Somex can offer peripheral components. Thanks to the modular component concept Somex can provide customised turnkey, small and economical deep hole drilling machines. Somex prefers to conduct tests with actual tools and material to prove the design and performance of a customized deep hole drilling operation. Tests are done at the factory using specific production tools under real production conditions. We use single cutting edge and carbide spiral drills up to 70 x Ø. Using this approach Somex can stand behind the design and performance and thus delivering practical and realistic results. The deep hole drilling process typically requires either a pilot-drill 1.5 x Ø or a drill guide bushing which is then followed by the deep hole drilling process. The unique Somex design combines the guide bushing with a chip basket, allowing both items to travel together. The movement of the guide bushing is air driven which helps to provide a much closer contact to the part thus preventing the escapement 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 centre line is greatly enhanced by a slow part rotation in counter-clock-wise direction. For deep hole drilling applications above Ø 18 mm, Somex has the option to equip its Max machining units with drilling systems from BTA- or Ejektor. In these applications, the coolant and chip management is accomplished through the spindle centre. The emulsion is collected at the backend of the spindle, filtered and pressurised to re-enter the coolant system. This solution is often used in high volume precision parts manufacturing such as automotive and other industries.
