Comprehensive Guide to WRM28H Wheel Repair CNC Machine

This post provides an in-depth look at the calibration and setup of the WRM28H wheel repair CNC machine, a vital tool for wheel refurbishment professionals.

For detailed specifications and features, you can visit the manufacturer’s page.

Understanding the Wheel Repair CNC Concept

The WRM28H is a specialized lathe designed for repairing surface scratches on aluminum wheels. It utilizes a high-precision touch probe to detect the surface curve of the wheel hub, employing a diamond cutter to effectively repair the wheel surface.

This PC wheel repair machine optimizes the curve directly, enhancing machining quality without requiring additional computers for special optimization, significantly saving time during the repair process. The user-friendly interface means that it’s easier to operate compared to traditional CNC wheel repair machines, as it does not necessitate specialized CNC training.

Users need not concern themselves with complex programming processes. The operation is streamlined via a touch screen and includes a wireless keyboard and mouse to accommodate various user preferences.

The machine functions with two primary tools: a diamond cutting wheel and a precision probe for scanning wheel curves. For the complete machine instructions, you can view them here.

Curve Optimization Process for Wheel Repair

Once the detection process is complete, the system will automatically transition to the curve optimization interface, displaying the current detected curve.

To optimize the curve, click on “Operation” in the top left corner, and then select “Filtering.” Further adjustments can be made by clicking “Point Range” to define specific points. Starting from the initial point, select nodes by double-clicking, before bending and after bending, and input appropriate values into the pop-up window. This will divide the entire curve into several sections for detailed optimization.

Input smaller values for segments with significant changes (for example, 2), and larger values for sections with minimal change (for example, 15). Larger input values generally yield better optimization results. However, if the chosen value is excessively large or if changes in the segment are minor, the optimized green curve may deviate from the original red curve.

Once points are selected, to perform the optimization, click “Operation” and then “Interpolate.” Post-optimization, the resulting green curve and the original red curve should ideally align closely, with only minimal deviation. If the deviation is substantial, click “Operation” and then “Clear.” After this, select “File” and then “Open” to re-initiate the detection process and re-optimization. Lastly, after completing the optimization, remember to select “Output Any Where” in the “File” menu to save your work. A success message will confirm when the saving is completed; click “OK” to finalize the process.

CNC Cutting Process for Wheel Repair

Based on my personal experience, it is best to operate the machine in step mode and control it manually. Always start 1 mm away from the wheel, gradually adjusting in 0.2 mm increments along the Z-direction for precision.

In the cutting section under the “Processing Parameter Table,” set “Single Cutting Depth” to 1.00 for the first cut, ensuring it begins 1 mm away from the wheel. For subsequent cuts, entering -0.2 will gradually bring the cutter closer to achieve the desired result.
