QC20 Ballbar for Machine Tool Verification
Renishaw's QC20 ballbar is highly regarded in the industry for its speed, simplicity, and effectiveness. As a trusted solution for machine tool performance verification, it streamlines processes and ensures compliance with international quality standards. Achieving stricter tolerances, meeting customer deadlines, and maintaining high standards doesn’t have to be complex. By incorporating simple steps like machine calibration, manufacturers can enhance precision and efficiency, making the QC20 ballbar an industry-leading tool for diagnostics.
What is a Ballbar?
A ballbar is a telescoping linear sensor with precision balls at both ends. The QC20 ballbar functions as a high-precision measurement device, used to evaluate a machine tool’s performance by detecting subtle variations in the radius as it traces a programmed circular path around a fixed mount. During operation, the sensor's balls are securely located within magnetic cups, facilitating accurate radius measurements.
Why Use a Ballbar?
Defects in component dimensions or surface finishes can arise from various causes, such as:
However, many issues originate from positioning errors within the machine tool, often due to geometric, dynamic, or mechanical play-related problems.
By identifying these errors quickly—often in just a few minutes—you can implement corrective actions efficiently, regardless of whether the machine is new or used.
Understanding your machine’s true capabilities is essential for defect-free production. This knowledge allows for effective production planning and necessary adjustments. Traditionally, this involved machining test parts, followed by time-consuming inspections. This method offers limited reliability when dealing with parts of varying geometries.
With the QC20 ballbar, machine tool performance can be evaluated effectively, providing actionable insights to maintain high-quality production.
