For a mechanical and high precision turning sub-contracting workshop, a good machine is a machine which "never" stops. In addition, if the produced parts are good, it is the winning equation. The mechanical workshop of Pierre Brunetti acquired a Miyano BNA 42 S turning centre last September and we wanted to know his opinion on this new machine. A full interview is to be discovered in our next issue.
The possibility to mount double or triple tool holders and to index the turret by half-position greatly increases the machining possibilities.
"It is unbelievable, look at this stainless steel part, we currently produce it, we’ve reached 4’500 pieces and apart from to the tool which cut the part, we haven’t had to correct anything on tools. The surface finish quality is also outstanding… it is a performance" says Mr. Brunetti in preamble. He adds: "The machine was installed last September and since that moment, it’s been turning and turning and turning". Up to 18 hours of production each day, 6 days a week on average and performance is excellent. Let’s see why Mr Brunetti bought the machine and what are his feeling after 6 months.
Compactness and efficiency "At first sight, I was a little concerned about ergonomics. The very fact of compactness implies that space to change tools is not very large. Hindsight, what I took for a drawback is in fact an advantage. The machining area is well thought, clean and pleasant" says the specialist working on the machine. He adds: "The number of tools that I found a little superfluous at first, especially with the use of double or triple tool holders and the ability to index the turret by half-positions in fact offers a large working comfort".
Profitability Working in good conditions is important, but the performance of the machine must also be up to the expectations of the company managers. In this regard Mr Brunetti is very clear: "The Miyano BNA 42 S brings us gains at all levels. Machining times are shortened, we can finish most of our parts completely in the machine, tools wear less and surface finish quality is excellent. In terms of accuracy, we produce parts in one-hundredth of a millimeter tolerance and the machine sticks to the center of the allowed range. From the first part in the morning to the evening, the quality is constant and we are within the tolerance". When questioned about its investment decision in retrospect, Mr Brunetti tells us he never regretted it, on the contrary.
