A new development at Dixi : 1 tool = 3 operations

June 2011

Dixi Polytool SA offers various options for internal micro threads. Dixi has in stock complete ranges of whirling tools, micro taps, micro thread formers as well as thread mills. With the launch of the new series of Dixi 1740 drilling thread whirlers, Dixi steps ahead with a new option for its customers’ needs.

Daily, Dixi’s customers face smaller and smaller series coupled with shorter delivery terms. Therefore the company’s R&D department has focused on defining a tool able to assure a process reliability, a high productivity and perfect shapes of threads. A combined tool has been developed allowing the replacement of the traditional drilling operation by a milling through circular interpolation in parallel to the machining of the thread.

Combined tool Dixi engineers conceived a combined tool allowing the replacement of the drilling operation by a milling through circular interpolation in parallel to a thread milling. This technique breaks the chips avoiding any filling. In addition, cutting forces are much lower in comparison to traditional drilling. A very serious development was made to optimize the geometry. This new tool is now available to machine at 2 or 3xD in most difficult to machine materials as for example titanium alloys, stainless steel or CrCo alloys. Their tool life is very similar to whirling tools but the process is much shorter…

High quality machining The reduction of the cycle time and the elimination of the traditional drilling process are not the only advantages: due to very low cutting forces, the tool can machine very large thread dimensions on machines with a low spindle power. One can also machine threads on inclinated surfaces. Dixi Polytool went even a step further: in addition an important frontal chamfer has been added. This allows chamfering of the drilled holes and reinforces the resistance of the frontal cutting edge. The cutting forces are directed towards the spindle axis in order to limit any vibration during the circular interpolation.

HORN HAS DEVELOPED THE NEW SG66 GRADE FOR TURNING WORKPIECES HAVING DIFFERENT HARDNESS ZONES

March 2024

When machining turned parts with hardened surface layers or with an interrupted cut, users quickly reach the limits of CBN inserts. This is where the new grade comes in. In combination with the fine-grain carbide, the aluminium-titanium-silicon chromium nitride layer delivers high performance when machining hardened steels up to 58 HRC. The maximum allowable temperature is 1,200 degrees Celsius (2,192 degrees Fahrenheit). Due to the high flexural strength of the carbide substrate, (...)
