Rigibore’s Zenith solution for the completely automated production of micron-accurate bores relies on Renishaw probing to facilitate the closed-loop tool compensation cycle that runs the machining process without stopping (and without manual intervention).

Roger Bassett, the chairman of Hayle-based Rigibore Ltd (www.rigibore.com), said: “The accuracy of the finished bore is completely reliant on the measurement provided.

“The measured value of the previous cut is sent directly to the machine control, where Rigibore macros monitor the measurement against pre-determined tolerance limits; if necessary, a cutting-edge compensation is applied.

“In some high-precision applications, the difference between a good part and a bad part is a matter of microns; and in some cases, if a bore is out of tolerance after machining, the part is not reworkable and therefore must be scrapped.

“These fine margins emphasise the importance of the performance and repeatability of Renishaw’s probing systems in providing the right information for the ActiveEdge tool’s cutting edge to be compensated.

“The Zenith closed-loop boring solution operates through a continuous cycle of boring, measurement and adjustment to ensure that bores stay between a pre-determined upper and lower tolerance limit.

“The combination of probing from Renishaw and automatic micron-accurate adjustment from Rigibore helps to ensure a bright future for precision machining.”
