How can we help you?

Are you commercializing a new product and need someone to manufacture the initial quantities as you ramp up for large-scale production? We can help. Do you have a really challenging low-volume part? Outsource it to us! Have you discontinued a product, but still need small quantities for maintenance and repair? Let us handle it. We want to be your trusted partner for small to medium production runs.

State of the Art Machines

Concepts NREC’s state-of-the-art manufacturing center features 5-axis CNC milling machines, (including a new Hermle C52 mill/turn), horizontal and vertical CNC lathes, and a Zeiss coordinate measuring machine (CMM) for precision inspection.

 

 

Best Software for Turbomachinery

We use MAX-PAC™ Computer-Aided Manufacturing (CAM) software, long recognized as the best CAM software for 5-axis milling of rotating bladed components, including impellers, blisks, and rotors. And, because we make the software, our machinist can work directly with developers to continuously improve the outcomes.

Trust the Experts in Turbomachinery

For over 60 years, we have helped leading global OEMs to improve the performance and manufacturability of their turbomachines.

This is a video of Concepts NREC's optional 3+2 Roughing Module that enables roughing out of impellers using 3-axis algorithms, keeping a constant tool vector. This strategy optimizes the toolpath to provide constant cutting load, making it suitable for high speed machining. This is extremely helpful for large (>0.5 m) diameter impellers and/or hard materials where roughing using the 5-axis strategies is less efficient.

What Are the 5 Axes in 5 Axis Machining?
by Christos Maninos, CAM Application Engineer & Peter Klein, Director, CAM Software
What is 5 axis machining? In short, it is manufacturing a component on a CNC milling machine that can travel in 5 different directions. These machines allow the cutting tool to reach around parts with a high degree of freedom. This makes them ideal for milling the complex shapes of turbo machinery components.

Increased Milling Capability and Capacity for Large 5-Axis Impellers
by Sean McDermott
Concepts NREC has added two additional Hermle 5-axis mills in our shop, and we’re excited  about the increased capabilities these new machines bring! In August of 2018 we received the  first of these mills, a 2018 Hermle C52uMT.  Just recently, in May of 2019, we added a Hermle C42u.  In addition to these new, state-of-the-art 5-axis Hermle mills, our shop utilizes a Mikron HSM600U, good for parts up to ~13” in diameter; a Hermle C40, which can mill parts up to ~20” in diameter, and a Mitsui Seiki HS5A-80, which can handle larger parts, up to ~32” in diameter.  We now have a full range of  5-axis mills capable of producing the most challenging parts from >1 inch up to over 39 inches in diameter.
