On the DMU50, the job could be hogged out on the outside, with all port holes hydraulics and even the inner holes machined without the need of separate set-ups. In the end, the part was made in just 4 set-ups, reducing the machining time by two-thirds and the scrap significantly. “We went from walking to running overnight,” Sharoni said. In comparison to the time that was necessary to complete machining of this part using a 4 –axis machine, the DMU50 dramatically reduced the machining time by more than 60%!

On another job, an order of 30 pieces had been run, only 18 were delivered and the others were being scrapped. When Sharoni informed the customer of the acquisition of the DMU50 and its inherent capabilities, owing to its rigid tolerances, the customer increased the order by an additional 20 pieces. The run time dropped from 20 hours to 4 hours, in that instance. “We went from a typewriter to a PC on this job,” says Sharoni. He said the DMU50 produces his parts 95 percent finished, in most cases, requiring only a small lathe and milling operations on the clamped side and inaccessible areas due to limitations of the rotating carrier of the table. In another occasion, a customer had a sand casting part that was very difficult to machine because of the variations in the castings. BAR has proposed to completely machine the part as an alternative to continue with the troublesome casting, or reinvest in a new casting process. The difficult part was machined in two days to the amazement of the customer that now seriously considers a complete hoggout.

By adding a rotary table to the DMU50, a six-axis cutting theater could be achieved, resulting in even greater flexibility, more jobs and increased profit, according to Asher Sharoni. With a 16-position tool changer, many of the jobs can be accommodated, though Sharoni notes he will be looking for a larger tool changer on his next five-axis machine, already under consideration for purchase. The shop is also looking into adding a simultaneous five-axis machine, which would enable it to move into the arena of blades and impellers.

Virtually any drawing or e-file format can be accommodated and the ShopMill program onboard the Siemens CNC can simulate the actual cutting path in a track-able sequences to determine the cycle time, prevent tool collisions and allow faster, more accurate quoting, while reducing scrap and time-to-first-part, Sharoni says. “The machine control actually modifies the part program, when needed, and that is a real asset to us, as we learn more about five-axis work on each shift.”

In addition to the machine tool and CNC technology, Asher Sharoni cited the superior service and support he received from Udo Herbes and his team at the local DMG tech center, as well as from Daniel Martinez, the Siemens CNC end user support manager for the West Coast, as key influencers in his decision to buy and likely buy again, from these companies. BAR is considering purchasing more DMU50/70 machines as it positions itself as experts in machining more difficult parts utilizing 5-6 axis machines as standard operations.
