Learn More →Brake disc problems such as runout, uneven thickness and unbalance can cause braking vibration and noise. Our machines check these on the production line, so you find problems before the discs leave your plant. Use this table to compare the six machines.
| Machine | What it checks | Set-up | Disc diameter | Cycle |
|---|---|---|---|---|
| M50-3 | Face runout, DTV and boss face runout | 3 probes. Manual, robot or truss manipulator loading | 255 – 360 mm | 30 s |
| M50-11 | The same checks, with up to 30 parameters in one cycle | 11 probes. Manual, robot or truss manipulator loading | 255 – 360 mm | 30 s |
| M50-X | Surface flaws (eddy current) and natural frequency | One station. Microphone or accelerometer | 255 – 360 mm | 30 s |
| Brake Disc Balancing Machine | Unbalance measurement and milling correction | Fully automatic cycle. Workpiece up to 30 kg | Up to 300 mm | 6 – 10 s to measure |
| M150 | Balancing, flaw detection, gauging and marking. Choose the functions you need | 5 stations. Automatic roller conveyors | 255 – 450 mm | 30 s |
| M160 | Dimensions, flaw detection, balancing, natural frequency and marking | 6 stations. Automatic roller conveyors | 255 – 450 mm | 30 s |
DTV means disc thickness variation. Specifications are for reference. Send us your disc drawing and we will confirm the details.
Start with the check that matters most for your discs.
Use the M50-3 for face runout, DTV and boss face runout. Choose the M50-11 when you want up to 30 parameters in one cycle.
See the M50-3The M50-X does surface eddy current flaw detection and natural frequency testing in one station. The inspection does not mark the disc.
See the M50-XThe brake disc balancing machine measures unbalance, mills material from the heavy spot and finishes in one automatic cycle.
See the balancing machineThe M150 cell and the M160 line bring gauging, flaw detection, balancing and marking together, so the disc does not move between separate machines.
See the M160Watch a fully automatic multi-station brake disc inspection and balancing system from MRLing.
▶It is a machine that checks brake discs on the production line. Depending on the model, it measures dimensions and runout, finds surface cracks with eddy current, tests natural frequency, and measures and corrects unbalance. Bad discs are found before they are shipped.
DTV means disc thickness variation. It is the difference in thickness around the disc. It is a leading cause of brake judder and vibration, so we measure it on the M50-3 and the M50-11.
Yes. The XYLD-30-4P-10 is a fully automatic brake disc balancing machine. It measures unbalance and corrects it by vertical or disc milling in one cycle, for workpieces up to 30 kg and 300 mm in diameter. The M150 and the M160 also include closed-loop dynamic balancing.
The M50 series covers discs from 255 mm to 360 mm in diameter. The M150 and the M160 cover 255 mm to 450 mm. The balancing machine handles discs up to 300 mm. If your disc is outside these ranges, send us the drawing and we will check.
Yes. The M50-X does surface eddy current flaw detection and natural frequency testing in one station. The natural frequency sensor can be a microphone or an accelerometer.
The M50-3 and the M50-11 support manual, robot or truss manipulator loading. The M150 and the M160 use automatic roller conveyors at the front and the rear.
Yes. See our brake drum page for balancing and inspection machines for brake drums.
Send us your disc drawing and the checks you need. We will recommend the right machine.
