About us


CNC PROS recognizes the rapid evolving advancements in the precision machining space and have put a very focused effort to offer advanced technologies to the Arizona market. To remain competitive in today's market, you must be able to offer your customer a better solution than your competition. From the CNC PROS 24 hour pledge, to our world class engineering and service team, CNC PROS exists to provide excellence for your machine tool and service choice. CNC PROS celebrated the grand opening on their new headquarters on May 1, 2019. Centrally located in the heart of Phoenix and less than 15 minutes from Sky Harbor airport, CNC PROS is proud to have the most advanced precision machining technologies in the world all under one roof in our world class showroom.

GROB Systems

GROB's one-of-a-kind design of HMC + swivel-rotary table is ideal for companies pursuing jobs in aerospace, die/mold, medical, and automotive sectors. The unique retractable spindle virtually eliminates the change for collisions during tool change, while maximizing the usable work area. This means GROB owners can usually buy one size smaller to reduce their investment, or have room to grow with new and larger part families. With these capabilities and GROB's accuracy and reliability, you can shorten production times, take on new jobs, and increase revenue.

Elevate your machining capabilities with these features:


  • Better access to more part features, including negative angles
  • Easy and complete chip removal when table is inverted
  • Your choice of several popular CNC control platforms
  • Many options included as standard
  • USA manufacturing, service & support (Bluffton, OH)
G350 – GROB precision
See for yourself the benefits of the G350 and experience our 5-axis machining center in action.
What our customers say

"We had never seen a machine configured like this, and we were excited to see how the swiveling and rotating capabilities were combined in the table."

“We like the unique configuration of the spindle versus the worktable as the spindle comes in horizontally ... You can machine unique cutting geometries and hard to reach areas. The configuration is also good for chip control.”

"You’re dealing with factory direct parts [GROB manufactures machine tools at its Bluffton, OH, plant] and technicians that are very knowledgeable and that was a big appeal for us.”

“If we have a problem that we’re trouble shooting, I can call GROB. They can log right into our machine, which is something that we’ve never had on any machine before, and they’ll trouble shoot for us. It really is a partnership with GROB.”


OPEN MIND Technologies will provide insight into CAM programming strategies during the GROB Technology Application Events. The technical presentation will focus on a sample of innovations that make direct impact on your productivity – assured tool paths that reduced the need for test cuts, higher production rates and improved part quality. The discussion will include hyperMILL MAXX Machining performance techniques for high performance roughing as well as finishing techniques that can provide up to 90% time savings by applying innovative tool paths that utilize conical barrel cutters.

Other topics include a series of techniques to improve part quality. Smooth overlap techniques bypass some of the physics encountered in machining to obtain improved blends at the junction of adjoining machining areas or machining jobs, even when programmed with different cutters. High-precision mode calculations produce fine surface finish using advanced mathematical techniques, reducing or eliminating faceted surfaces often found during machining.

New rest machining techniques use automated and highly productive combination of parallel and z-level rest machining tool paths into an optimal process. These rest machining tool paths can also be combined with the smooth overlap functions to assure blending with adjacent surface walls.

In addition to postprocessing and simulating computed tool paths, we will be introducing topics related to hyperMILL’s Virtual Machine. Virtual Machine’s revolutionary functions were created to optimize and idealize machine tool movement when delivering programmed toolpath safely to the targeted machine.

GROB and OPEN MIND have collaborated on the machining demos that will be on display during the Technology Application Event.


As an industry leader in advanced CNC technology, the SINUMERIK controller from Siemens is at the forefront of many exciting advancements in modern CNC design. Come and see how the SINUMERIK 840D sl can make advanced machining technologies such as 5-axis and mill-turning not only accessible, but easy to understand and use.

SINUMERIK achieves this through its intuitive graphical user interface and cycle design and enables new machine tool users to become efficient and productive very quickly.
