A short informative case study video is available from Advance Carbide Tooling Ltd. This illustrates the practical advantages associated with their Mircona tooling range for the production of high quality turned parts.

It features TJ Smyth & Co. at their Portchester plant, who are specialists in the production of precision components for the hydraulic and automotive industries. They have a number of CNC lathes and the case study involves the production of a turned valve part on a Miyano BNC34T CNC machine. This has a limited number of tooling stations so that the conventional method of machining using left and right hand toolholders took up too many stations in the turret.

Sideways or axial turning was investigated as an alternative, using grooving tools from a number of suppliers. This proved to be unsuccessful due to the high rate of tool breakages until the Mircona range was tried. The Mircona products feature side reinforced toolholders which can be fitted with a selection of inserts of varying grades and geometries to cover most machining applications, including use on difficult and even exotic materials. An additional benefit experienced with the Mircona tools was a considerable reduction in the machining cycle times.

The video illustrates production where the steel component has a manufacturing tolerance of 0.05mm. However, in practice TJ Smyth determined that 0.03mm tolerance could be maintained constantly with this tooling. The depth of cut is 2.75mm with a feed rate of between 0.2 and 0.25mm per revolution, combined with surface speeds of 90 to 130 metres per minute.

Under these working conditions an insert life of 40 minutes was obtained, during which 200 components were produced. The surface finish remained consistently high throughout the run, and the reliability of the tooling being described as excellent by the user.
