Maximizing Machine Uptime through Proactive Care
In plate and angle rolling, unexpected downtime is a productivity killer. When a plate roll or angle roll stops, your fabrication line halts, risking missed delivery dates, mounting idle labor costs, and repairs. Rolling processes demand consistent hydraulic pressure, mechanical alignment, and electronic synchronization. Waiting for a component to fail before taking action is a risk your production schedule cannot afford.
Davi Preventive Maintenance Programs are designed to eliminate the risks of unexpected outages and maintain your machines in peak operating condition. Instead of reacting to failures, our structured, periodic service visits stop technical issues before they disrupt your shop floor. By combining physical diagnostic checks with digital monitoring, we ensure your rolling systems continue to deliver maximum precision, safety, and performance.

Preventative care lowers the risk of catastrophic failures, keeping your production schedule on track.
Consistent Bending Precision
Routine checks ensure that alignment systems, like the patented Servo-Tronic roll parallelism system, remain accurate to within fractions of a millimeter/inch.
Optimized Safety Standards
Our technicians inspect and verify all active and passive safety barriers, light curtains, and emergency stop devices to protect your operators.
Predictable Operational Costs
Fixed-price packages turn unexpected emergency repairs into a planned, manageable operational expense.
TECHNICAL FAQ
Preventive Maintenance
Regular preventive maintenance preserves the natural force distribution of your Davi MAV 3-roll variable axis plate roll by verifying the pressure balance and mechanical alignment of the hydraulic cylinders. Because these high-capacity machines utilize a geometrically and hydraulically symmetrical "push-push" or "pull-pull" configuration where all cylinders have the exact same displacement, periodic calibration prevents uneven wear on cylinder seals and keeps frame stress uniform. Protecting this built-in symmetry guarantees highly precise workpiece dimensional tolerances and prevents you from having to continuously override or rely on electronic parallelism adjustments during demanding heavy-duty or re-rolling runs.
The patented Servo-Tronic system acts as your plate roll's primary defense against leveling errors and unbalanced loads, utilizing dual mechanical-hydraulic and fine-tuning electro-valve controls to keep the rolls perfectly parallel. Over time, contaminated hydraulic fluid or micro-deviations in flow rates can cause minor timing discrepancies between the cylinder-specific pumping groups. Scheduled preventive maintenance visits ensure that fluid mass flows, dedicated mechanical pumping groups, and fast-responding roll-by-wire control architectures are fully cleaned, tested, and calibrated, reducing electronic reliance and keeping your MCA or MCB 4-roll machine running at maximum positioning accuracy even if a digital backup fails.
While Davi’s planetary guide technology features permanently lubricated bearings that eliminate the need for daily manual grease runs and protect the mechanism from abrasive mill-scale, periodic technical inspections are still essential to maximize service life. During scheduled maintenance visits, our technicians check the pivoting points, check for scale accumulation, and inspect the structural integrity of the planetary assembly's rotation path under bending load. This proactive care ensures that the side rolls continue to execute their circular-path travel around the top roll with minimal friction, preserving your ability to roll tight-diameter cans as small as 1.1 times the top roll diameter.
For Davi MCP double-pinch angle rolls, our preventive maintenance visits focus heavily on testing the three independent hydraulic roll motors and calibrating the exclusive Davi Torque Management System (DTMS). Our service engineers check individual motor pressures, clean hydraulic manifolds, and run digital diagnostics on the torque-balancing valves to ensure perfect contact speed synchronization, even when using universal rolls or bending profiles with varying outer diameters. This targeted check ensures maximum torque distribution to the section with zero slippage, preventing profiles from getting stuck and keeping automated 3D forming operations smooth and repeatable.
