HARRISON Product Lines We Repair
Our engineers are trained on the full HARRISON product range. Below are the major product families we service.
Harrison Alpha Series CNC Lathes
Compact and mid-range CNC turning centers used in precision component manufacturing. Common issues include spindle bearing wear, servo drive faults, and control system calibration loss affecting dimensional accuracy.
Harrison Masturn Manual Lathes
Robust manual precision lathes for traditional turning and threading. Repairs often involve gear train alignment, spindle runout correction, feed mechanism restoration, and electrical wiring troubleshooting.
Harrison iSmart CNC Control Systems
Modern parametric controllers managing tool paths, spindle speed, and coolant flow. Fault codes, software crashes, and encoder interface failures are typical repair scenarios in Indian plants.
Harrison Spindle Drive Units
Direct-drive and belt-drive spindle assemblies delivering high-speed precision rotation. Common faults include bearing preload loss, thermal runaway, and speed feedback sensor malfunction.
Harrison Servo Axis Motors and Encoders
Stepper and servo motors controlling X, Y, Z axis movement with absolute position feedback. Issues include encoder calibration drift, motor winding shorts, and resolver interface failures affecting repeatability.
Harrison Hydraulic Pressure Control Systems
Pump, valve, and accumulator assemblies regulating clamp force, tool changer pressure, and coolant delivery. Repairs address pump cavitation, solenoid coil burnout, and manifold valve stiction.

Common HARRISON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HARRISON equipment arriving at our workshop.
- ✓Spindle bearing preload loss and runout — Harrison spindle bearings experience micro-sliding and thermal fatigue under continuous CNC operation, causing race surface degradation and runout exceeding 0.025 mm, compromising surface finish and tool life in high-volume Indian automotive suppliers.
- ✓iSmart controller fault codes E201, E305, E410 — Harrison iSmart CNC systems display these codes due to encoder signal loss (E201), servo drive communication fault (E305), or spindle speed feedback error (E410), often triggered by dust ingress, cable corrosion, or resolver connector pin oxidation in humid Indian shop floors.
- ✓Servo motor winding insulation breakdown — Harrison servo motors in X-Y-Z axes deteriorate due to thermal stress from continuous operation, moisture infiltration in coastal or humid Indian plants, and voltage transients from unregulated power supply causing inter-phase short circuits.
- ✓Tool changer hydraulic pressure drop and jerky movement — Harrison hydraulic clamp systems lose pressure due to poppet valve erosion, internal pump leakage from cavitation, or accumulator pre-charge loss, causing inconsistent tool grip and positioning delays in high-speed production runs.
- ✓DRO (Digital Readout) display malfunction and coordinate loss — Harrison DRO systems lose coordinate memory and display garbled characters due to CMOS battery depletion, corrupted ROM firmware, or damaged glass scale tape on manual Masturn lathes, especially after extended idle periods.
- ✓Gear train backlash and feed rate inconsistency — Manual Harrison lathes develop excessive backlash in spindle drive gears and feed spindle after years of use in Indian job shops, causing chatter, dimensional drift, and poor surface finish in precision turning operations.

Frequently Asked Questions — HARRISON Repairs
Do you repair Harrison equipment anywhere in India?+
Yes. Synchronics repairs the complete Harrison product range - CNC lathes, manual turning centers, iSmart controllers, spindle drives, servo motors, and hydraulic systems. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, and all other cities. Full repair and testing occurs at our Vadodara, Gujarat facility with 180+ engineers and 30+ years of industrial electronics expertise.
Can Synchronics repair older Harrison Masturn manual lathes and restore original DRO systems?+
Absolutely. We specialize in restoring vintage Harrison Masturn lathes (210, 260, 280 series) including mechanical feed systems, spindle bearings, and legacy DRO units. We source OEM replacement parts, re-calibrate glass scales, and validate precision to original specifications. Many Indian job shops rely on us to extend Masturn machine life at 40% lower cost than new equipment purchase.
What is the typical turnaround time for Harrison Alpha CNC lathe control system repair?+
For iSmart controller faults and servo drive issues, Synchronics typically completes diagnosis within 2 days and repair within 5-7 working days depending on parts availability. Critical faults (E-codes, servo failures) receive priority processing. We maintain a stock of common Harrison replacement boards and modules at our Vadodara headquarters to minimize downtime for Indian manufacturers.
Do you offer on-site diagnostics and repair for Harrison equipment at customer facilities?+
Yes. For large installations or urgent production issues, Synchronics dispatches trained field engineers to your plant in Vadodara, Gujarat and nearby regions for on-site troubleshooting, component testing, and repair. We carry diagnostic equipment including oscilloscopes, megohm meters, and spindle runout gauges to identify faults quickly and minimize line stoppage.
Can Synchronics help with Harrison lathe modernization - upgrading manual controls to CNC or retrofitting new servo systems?+
Yes. Beyond repair, Synchronics consults on Harrison lathe modernization projects including spindle servo upgrades, DRO installation, and control system retrofits. We have experience integrating modern stepper/servo motors, new control boards, and feedback systems while preserving the Harrison mechanical structure, helping Indian manufacturers improve precision and productivity at lower cost than machine replacement.
How do I send my HARRISON 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 HARRISON 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 HARRISON 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 HARRISON 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.
