MAHR Equipment We Repair — By Category
MAHR Product Lines We Repair
Our engineers are trained on the full MAHR product range. Below are the major product families we service.
MarSurf
MAHR's portable and stationary surface roughness measurement system. Common issues include stylus wear, signal noise in wireless transmission, battery charging failures in mobile units, and calibration drift affecting Ra/Rz accuracy reporting.
MarCator
MAHR precision electronic dial indicators and digital length comparators. Frequent faults include LCD segment failure, mechanical wear in spindle bearings, dead battery contact corrosion, and impact damage to electronic circuitry from drop events in tool rooms.
Coordinate Measuring Machines (CMM) Control Systems
MAHR CNC and manual CMM drive electronics, probe interfaces, and measurement software controllers. Failures include motor driver board faults, probe signal conditioning errors, sensor calibration loss, and communication interface breakdowns (RS-232, Ethernet, Profibus) causing production stoppages.
Optiv and Absolute Arm Systems
Portable coordinate measuring machines with optical and mechanical probe integration. Common repair needs include articulation joint friction resistance changes, optical camera focus misalignment, probe zero-point repeatability loss, and software licensing resets after component replacement.
Microgage and Analog Probe Systems
Analog and hybrid electronic probe interfaces for manual and CNC CMMs. Repair involves electrical contact corrosion in multi-pin probe connectors, signal amplifier board failures, LVDT sensor drift, and compatibility testing after firmware updates on legacy systems.
Testing Machines and Length Comparators
MAHR precision length measurement, tool inspection, and hardness testing electronics. Issues include load cell amplifier failures, analogue-to-digital conversion errors, mechanical backlash compensation sensor malfunction, and calibration certificate expiry affecting metrological status.

Common MAHR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in MAHR equipment arriving at our workshop.
- ✓LCD display segments dead or flickering — MAHR MarCator and digital indicator LCDs fail due to prolonged vibration exposure on shop floors, thermal cycling in foundry environments, and age-related LCD segment driver failures. Cold solder joints on display connector pins are common in units exposed to humidity.
- ✓Probe signal loss or erratic readings — MAHR CMM probe interfaces suffer intermittent signal loss when probe cables develop internal breaks, probe connector pins corrode due to coolant spray or humidity, or the probe zero-point calibration drifts after mechanical impact. Software version mismatches can also cause unrecognised probe signals.
- ✓MarSurf surface roughness gauge wireless connection failure — MAHR MarSurf mobile and wireless units lose Bluetooth or proprietary wireless connection due to antenna corrosion, software stack crashes after Android/iOS updates, or frequency interference from nearby welding equipment. Battery charging ports develop corrosion in humid industrial environments.
- ✓CMM motor driver not responding or axis movement stalled — MAHR CMM drive electronics fail when motor driver FETs overheat from continuous spindle operation, encoder signal cables develop frayed insulation causing axis-position feedback loss, or stepper/servo motor control signals become corrupted after coolant ingress into control cabinet connectors.
- ✓Calibration data loss or incorrect dimensional readings — MAHR measurement instruments lose stored calibration when backup batteries in PCBs deplete (typical 5-7 year life), EEPROM cells become corrupted due to power supply transients, or after unauthorised firmware updates. Indian foundry applications using older MAHR units are particularly vulnerable.
- ✓Ethernet/Profibus communication protocol timeout or disconnection — MAHR CMM controllers and MarSurf networked units experience communication failures due to cable shielding degradation, misconfigured network addresses (IP conflicts), failed Ethernet transformers on control cards, or incompatible Profibus gateway firmware versions after plant network upgrades.

Frequently Asked Questions — MAHR Repairs
Do you repair MAHR equipment anywhere in India?+
Yes. Synchronics repairs the complete MAHR measurement and gauging portfolio — MarSurf, MarCator, CMM control systems, and Optiv probe interfaces — across all of India. We offer same-day PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities, with centralised repair facility in Vadodara, Gujarat. Turnaround is typically 5-7 working days including metrological recalibration.
Can you recalibrate MAHR CMM and MarSurf equipment to ISO 10360 / ISO 4288 standards?+
Yes. Synchronics maintains BIS-traceable calibration standards and performs full metrological re-certification of MAHR CMM systems to ISO 10360 Part 2/3 specifications, and MarSurf surface roughness gauges to ISO 4288 and ISO 11562. We issue internationally recognised calibration certificates with measurement uncertainty budgets, essential for automotive OEM supply, aerospace traceability, and ISO 9001/TS 16949 certification. Calibration is performed post-repair using MAHR reference spheres and certified surface samples.
What is the typical repair cost and warranty for MAHR CMM controller repairs?+
MAHR CMM control board repairs (motor drivers, encoder interfaces, Ethernet modules) typically range INR 8,000-25,000 depending on component complexity. Major repairs (full control cabinet rebuild) can reach INR 40,000-80,000. All repairs carry a 12-month warranty on replaced components and labour. If your MAHR CMM system suffers repeated faults due to environmental contamination, Synchronics also advises on cabinet enclosure upgrades and electrical protection strategies suited to Indian foundry and machine-shop conditions.
Do you stock MAHR spare parts like probes, styluses, and LCD display modules?+
Synchronics maintains in-stock inventory of high-demand MAHR spare parts including MarCator LCD panels, MarSurf probe styluses, CMM probe connectors, motor driver modules, and encoder cables. For obsolete or long-lead MAHR components (>4 weeks from Germany), we coordinate expedited procurement through our supplier network and offer temporary loaner units where available. Contact our spares team for current stock and pricing.
Which MAHR products are most commonly repaired in Indian manufacturing plants?+
In Indian automotive Tier-1 supply, we repair MarSurf surface roughness gauges (critical for engine component finish control) and MarCator digital indicators (used in receiving inspection). In aerospace and defence foundries, MAHR CMM systems and Optiv arms are repaired frequently due to coolant contamination and vibration-induced probe failures. Tool-rooms and precision job-shops typically require MarCator indicator repairs and MarSurf mobile unit recalibration. Synchronics has specialised repair pathways for each application context and maintains industry-specific parts inventory to minimise downtime.
How do I send my MAHR unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a MAHR drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on MAHR repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your MAHR unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
