Accuracy problems in surface grinding – causes and solutions

In surface grinding within toolmaking, several factors affect the accuracy of workpieces. The most common causes include:

• Human errors during machining: Inattention, non-compliant machine operation and insufficient mastery of grinding technology lead to calculation and setting errors and thus to accuracy deviations on the workpiece.
• Programming problems: If CNC programs are run in an open loop without using the intelligent control functions, the machine cannot exploit its full potential.
• Tool and selection errors: An unsuitable machine selection for the specific task or insufficient accuracy of the tool itself limits the achievable machining accuracy.

How to eliminate the most common causes

Train your staff regularly and define binding operating procedures. Use the intelligent functions of your CNC control – closed control loops and automatic compensation functions balance out systematic errors. Also check whether the machine selection fits the task and whether the tool and clamping allow the required accuracy.

Anyone who systematically addresses these points noticeably reduces scrap and rework and reliably ensures the required workpiece accuracy in the long term.
