Fully Automated Brake Disc Inspection Cell — Dynamic Balancing, Gauging and Marking
MRLing's fully automated brake disc inspection cell — a modular, multi-station system integrating dynamic balancing, NDT (eddy current and natural frequency), dimensional gauging and marking, with automatic roller conveyors at the front and rear.
The M150 is a fully automated, five-station brake disc inspection cell built on a modular architecture. Dynamic balancing, NDT (eddy current and natural frequency), dimensional gauging and marking can be freely combined — any three of these functions form the internal inspection stations, with fully automatic roller conveyors configured at the front and rear.
The cell includes closed-loop dynamic balancing, 9 simultaneous eddy current flaw detection sensors, dynamic relative dimensional measurement with 11 standard measuring points, and pneumatic pin or laser marking. Covering discs from 255mm to 450mm OD and up to 85mm part height, it runs on a 45kW supply with 4–6 bar air and weighs 6t.

Configuration depends on the functions you choose. Send us your disc drawing and we will confirm the details.
Balancing, NDT, dimensional gauging and marking integrate into a high-density multi-station cell — any three functions form three internal stations.
Unbalance measurement, automated milling correction and final audit execute within a single station.
Nine flaw detection sensors operate simultaneously, including disc surface scanning.
Both accelerometer and microphone sensors can be used for sampling.
Dynamic relative measurement with 11 standard measuring points covering nearly all critical parameters for stable runout and DTV results.
Standard pneumatic pin or laser marking; optional laser QR code marking available on request.
One cell checks three different things on every brake disc. Each uses its own sensor type, so the results are reliable and easy to trace.
The disc is measured dynamically while it rotates. LVDT sensors record the position of the disc surfaces at 11 standard measuring points. The system calculates the dimension and runout results from these readings.
Piezoelectric sensors pick up the force caused by unbalance as the disc spins. The machine finds the amount and the angle, mills material from the heavy spot, then measures again to confirm the result. This is a closed loop.
Nine eddy current sensors scan the disc surface at the same time to find cracks and other surface flaws. Natural frequency testing with an accelerometer or microphone is also available.

▶The M150 combines closed-loop dynamic balancing, eddy current flaw detection, natural frequency testing, dimensional gauging and marking. The disc stays in one cell, so you do not need to move it between separate machines.
Yes. The M150 is modular. Balancing, NDT, gauging and marking can be freely combined, and any three form the internal inspection stations. Tell us which checks your process needs and we will propose a configuration.
The M150 covers brake discs from 255 mm to 450 mm outer diameter and up to 85 mm part height.
The M150 is built for a 30-second cycle time.
Dimensions are measured with LVDT displacement sensors. Balancing uses piezoelectric sensors. Crack detection uses eddy current sensors. Natural frequency testing uses an accelerometer or a microphone.
Every disc can be marked with a pneumatic pin or a laser, including an optional laser QR code. The code links the disc to its dimension, balance and flaw detection results.
The M150 runs on a 45 kW power supply and 4 – 6 bar compressed air. The machine weighs 6 t. Automatic roller conveyors are fitted at the front and the rear.
The M150 is one of our brake disc inspection systems. See the full range on the brake disc inspection page, or compare these machines.
