Production On The Line: 9 Reasons Your Rolls Need CNC Grinding

Posted by Robert Rourke on Sep 11, 2014 12:20:00 PM

More and more manufacturers are switching from manual to CNC grinders. With better lead time and productivity, hands-off programming, higher accuracy and tighter tolerances, automated CNC grinding is quickly becoming a no-brainer for production efficiency

WHAT IS CNC GRINDING?
Numerical control (NC) is the automation of machine tools operated by precisely programmed commands encoded on a storage medium. This is in opposition to manual control via hand wheels or levers, or mechanical automation via computer-aided manufacturing (CAM) programs.

Most NC today is computer numerical control (CNC), which simply means that computers play an integral role in controlling the systems.

WHY DOES YOUR INDUSTRY LOVE CNC GRINDING?

1. When properly set up in the proper environment, you get a variety of options for your profile.

  • Proper setup:
    • Bearings and housings are removed.
    • Bearings seat is ground round and concentric to the roll face.
  • Proper environment:
    • Temperature is controlled.
    • Foundation is isolated.
2. You’re able to make three-dimensional grinds, which is very important for certain roll grinding situations and specialized products.
  • 3D grinds are crucial for rolls that fit the following scenarios:
    • Running at over 285 degrees F
    • Used for making critical products, which may have minimal caliper variation
    • Used for products that need outstanding surface uniformity

Screen_Shot_2014-08-28_at_12.14.10_PMIf you had to choose between achieving greater or lesser profitability, revenue and productivity, your decision would be a no-brainer. But real-life choices aren’t always so clear. Add in upfront, short-term costs, and it’s easy to lose sight of your desired long-term results. When it comes to precision grinding, the same holds true.

Roll grinding services are essential to achieving better product yield, reduced operational interruption and less downtime. But some companies choose to take on such a project internally, under the false assumption that it costs less than seeking out a roll maintenance expert.
