Ramco Machine, LLC | Rowley, MA, USA

Ramco Machine, LLC is a family owned and operated CNC machine shop. Their 24,000 square foot facility utilizes highly skilled, self-reliant employees combined with the latest CNC machine tools available. For more than 30 years, RAMCO has been manufacturing products that have enriched our lives.

Ramco specializes in complex milled and turned parts that must meet stringent tolerances and be delivered with fast turn­around times. They take on many interesting projects, and among other types of work they support robotics companies, medical manufacturers, and occasionally build re­placement parts for vintage Ferrari’s and other exotic cars. And now RAMCO is helping to impact the future of space exploration by ma­king parts for an advanced NASA satellite mission.

First 5‑axis machine

To get to this point, Ramco entered the world of 5‑axis machining. Vice President Mike Jezowski explains, “In order to efficiently produce some of the complex parts that come in, we had to go to 5‑axis machining. To be competitive, we had no other choice.” Ramco decided to purchase a DMG MORI, DMU 65 FD mono­BLOCK high-end mill and turn machining center. They then searched for highly reliable CAM soft­ware that would efficiently control all the capabilities of this sophisticated 5‑axis machine.

High quality CAM soft­ware

Ramco chose hyperMILL® from OPEN MIND Technologies. Mike explained that, “We chose hyperMILL®, be­cause when you buy high quality equipment like the DMU 65 you need high quality CAM soft­ware to pro­gram it. hyperMILL® was the perfect solution. I had already researched CAM soft­ware for several years be­fo­re we bought the machine, so the day we received the 5‑axis machine, I ordered hyperMILL® soft­ware.”

“We got hyperMILL®, because when you buy a high quality piece of equipment you need high quality CAM Soft­ware to program it. hyperMILL® CAM soft­ware handles the complex parts that we make and I haven’t found anything that it can’t do.”

Discovering new horizons takes accuracy

Ramco was recently contracted by MIT Lincoln Laboratory to fabricate the critical camera mount brackets for an important NASA TESS sa­tel­li­te mission. Making the mounting brackets required machining Invar, a nickel-iron alloy with a low thermal expansion coefficient, allowing it to meet the rigors of launch and enabling it to compensate for the ex­tre­me temperature swings of outer space. The mounting bracket has exceedingly tight tolerances. The central rib’s thickness is .050” +/- .001”, perpendicularity between sur­faces is held to .001” and the brac­ket’s two opposing surfaces must be in-line with each other to within .001”.

Very tight tolerances

To cut Invar and achieve the required tolerances Mike Jezowski used a hyperMILL® generated 5‑axis profile finish tool path. By doing this, he was able to achieve an accurate finish across each part, keeping them within these very tight tolerances. The four-camera mounting brackets were shipped on time, and will soon be on their way to ex­plo­re outer space.
Mike said, “hyperMILL® helps my bottom line because I can be sure the part we make is perfect. That makes a big difference. If you’re making bad parts it’s hard to meet costs. I haven’t found any­thing that the soft­ware isn’t able to do.”
