DAVENPORT Product Lines We Repair
Our engineers are trained on the full DAVENPORT product range. Below are the major product families we service.
Davenport Multi-Spindle Automatics
High-speed, multi-spindle screw machines for mass production of fasteners, shafts, and precision components. Common issues include spindle bearing wear, transmission slippage, and electrical control panel failures affecting production speed and part accuracy.
Davenport Transfer Machines
Transfer-type automatics for complex multi-operation part production. Typical faults involve indexing failures, tooling breakage detection circuits, and servo positioning errors that halt production runs.
Davenport Servo Drive Systems
Electronic servo controls for spindle speed regulation and feed control. Common failures include servo amplifier board degradation, encoder signal loss, and PLC communication faults.
Davenport Pneumatic Control Modules
Air-operated indexing, clamping, and tooling circuits integral to machine automation. Typical problems are solenoid valve burnout, pressure regulator drift, and air cylinder seal leakage.
Davenport Electrical Control Panels
Main switchgear, motor starters, and relay logic panels controlling machine operation. Common faults include contactor pitting, thermal overload relay calibration drift, and wiring harness corrosion.

Common DAVENPORT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DAVENPORT equipment arriving at our workshop.
- ✓Spindle motor bearing excessive heat generation — Davenport multi-spindle machines operate at 1500-3000 rpm continuously. Bearing wear, inadequate lubrication, or spindle runout causes friction and overheating, eventually seizing the spindle and halting production.
- ✓Transmission slippage during high-load threading operations — Davenport gear trains and friction drive systems wear over years of continuous production. Belt slippage, gear tooth damage, or clutch plate wear causes spindle speed to drop unpredictably, producing out-of-tolerance parts.
- ✓Servo drive amplifier board failure with error code display — Davenport retrofit servo systems use aging electronic boards prone to capacitor failure, solder joint cracking, and component thermal drift. Power surges and poor facility grounding accelerate board degradation.
- ✓Pneumatic solenoid valve coil burnout preventing tooling actuation — Davenport air-operated indexing and tool-change circuits use 24 VDC solenoids exposed to electrical spikes, dust contamination, and thermal stress. Coil insulation failure causes no-signal condition and production halt.
- ✓Electrical contactor chattering and pitting in motor starter circuit — Davenport motors drawing 20-50 amps at startup cause arcing across contactor contacts. Years of switching, plus inadequate contact pressure, produce pitting and electrical resistance rise, creating heat and potential faults.
- ✓Thermal overload relay nuisance tripping during normal operation — Davenport thermal overloads drift with age and temperature cycling. Incorrectly calibrated relays trip at 70-80% of nameplate current, falsely indicating motor overload and stopping production unnecessarily.

Frequently Asked Questions — DAVENPORT Repairs
Do you repair Davenport automatic screw machines anywhere in India?+
Yes. Synchronics specializes in Davenport multi-spindle automatics, transfer machines, and servo controls. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all industrial cities. Your machine ships to our 35,000 sq ft facility in Vadodara, Gujarat, where 180+ engineers diagnose and repair with OEM-equivalent parts and testing.
What is the typical repair turnaround for a Davenport spindle motor bearing failure?+
Simple bearing replacement typically takes 5-7 business days. If spindle runout is excessive or gear train damage is present, diagnostic and rebuild phases extend turnaround to 10-14 days. Synchronics keeps common Davenport spindle bearings in stock and performs thermal runoff testing before return, ensuring zero rework.
Can you retrofit my vintage Davenport multi-spindle automatic with modern servo controls?+
Absolutely. Synchronics has retrofitted 50+ Davenport machines with modern AC servo drives, PLC controllers, and condition monitoring. We preserve the original mechanical design while adding digital spindle speed feedback, predictive maintenance sensors, and Industry 4.0 connectivity. Each retrofit is validated with 40-hour test-run protocols.
How do I know if my Davenport transmission needs overhaul versus simple adjustment?+
Synchronics performs non-destructive gear backlash measurement and torque testing. If backlash exceeds 0.010 inch or spindle torque is below 80% of nameplate, transmission rebuild is necessary. We provide written assessment with before-after torque data so you understand the repair scope and ROI.
Do you have experience with Davenport pneumatic control retrofits and troubleshooting?+
Yes. Synchronics repairs and upgrades Davenport air-operated indexing, clamping, and tool-change circuits. We replace aged solenoids, recalibrate pressure regulators, service air filters, and perform full pneumatic circuit pressure verification. Many Indian fastener plants have upgraded their Davenport machines under our guidance.
How do I send my DAVENPORT 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 DAVENPORT 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 DAVENPORT 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 DAVENPORT 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.
