The Engineering Challenge

More than moving five motors.

The challenge was to coordinate motion, sensor feedback and polishing sequences while giving the operator practical control over the machine.

Motion coordination

Manage axis positioning and sequencing across the polishing cycle.

Control logic

Translate a complex polishing process into embedded operating behavior.

System integration

Bring mechanics, electronics, power and operator interaction together.

Our Engineering Scope

We engineered the complete system around the process.

Motors & Mechanical Integration

Motor selection, drive requirements and mechanical connection interfaces.

Sensors & Feedback

Sensor selection, interfacing and feedback integration.

Custom Electronics

Main controller PCB, motor-drive electronics and power-supply design.

Algorithms & Firmware

Polishing sequences, five-axis coordination and machine operating logic.

Operator Interface

Screen graphics, menu workflows and keypad design.

Prototype to Production

Prototype builds, integration, validation and production engineering.
