ACCRETECH SBS Process Control Systems

Sensors & Software strategies for machine tool process control

ACCRETECH’s SBS product line includes some of the most advanced and comprehensive machine tool process control currently available on the market.

Process monitoring involves the detection and analysis of high frequency noise (acoustic emission or AE) generated by the machining or grinding process. The AE-1000 and the AEMS add-in card for the SB-5500 help reduce air grind time and provide automatic crash protection by using proprietary acoustic detection technology.

ACCRETECH SBS offers different versions of AEMS (Acoustical Emission Monitoring System) that provide our customers the capability to monitor their grinding process with exceptional precision.
The AE-1000 acoustic monitor is a basic control that offers crash protection and two programmable process limits that can be used for Gap elimination or monitoring grind quality.
The AEMS add-in card for the SB-5500 control offers more flexibility with a separate Gap and Crash Limit, as well as sixteen sets of programmable process limits.
The AEMS product line uses proprietary acoustic sensor technology to monitor the high frequency signals generated on the grinding machine structure during key events in the grinding process.

The user can set up the system easily and quickly, and immediately reap the benefits of improved control over the machining process.

Advantages of SBS AE-1000 and AEMS (Acoustic Emission Monitoring System):

  • Touch detection on part within milliseconds/ sub-microns. Eliminate grinder burn during first touch. Control grinding force on part. Reduce scrap
  • Gap Elimination – reduce air-grinding time at grinding feed rate. Typical 10 – 15% cycle time reduction achieved
  • Crash prevention – monitor for excessive acoustic noise produced by a crash event onto parts, tooling or dresser. Wrong part, incorrectly loaded part, wrong program, wrong offsets etc. Detect within less than 1 millisecond and stop infeed/ retract wheel-head to prevent damage. Prevent machine, wheel and tooling damage, save money
  • Detect unexpected events during the grinding cycle. Part stops/ part slipping on chuck, reduce excessive force during grinding. Reduce scrap
  • Grinding process monitoring. Monitor part roundness/ black part clean-up. Monitor for excessive grinding force during rough grinding. Reduce grinder burn. Maximise dressing intervals. Increase productivity
  • Dressing process monitoring. Monitor for full wheel clean-up. Monitor and correct dressing profile – look for defects during dressing. Minimise dress passes. Increase abrasive and diamond life – reducing costs

ACCRETECH also offer a high-end process monitoring add-in card for the SB-5500 controller series, called ExactControlTM. Not only can ExactControlTM monitor up to up to 6 acoustic emission sensors be added at one time (2 simultaneously), but additional third party sensors such as power, current and temperature can also be added.
