Description:

This control board came from a project for an overseas machinery partner that builds heavy-duty cutting equipment for metal processing workshops. Their old controller tripped often under high-load cutting, and signal interference from nearby motor drives caused random stops during continuous production. We reworked the whole PCBA layout to fit their existing machine enclosure, so they avoided redesigning the mechanical housing, extra mould modification costs, and a longer project lead time. Ningbo MingXi is a PCB assembly manufacturer in China for machinery builders and OEMs.

Key Functions

Main motor drive control: controls the cutting machine drive.
Real-time current sampling: monitors current during cutting.
Over-current and over-voltage protection: protects the drive and the board.
Ethernet port for debugging: field communication for on-site debugging.
Power ripple suppression: large-capacity electrolytic capacitors stabilize the power input during sharp current surges when cutting hard metal blanks.
Signal isolation: multiple optocouplers isolate input and output signals to suppress electromagnetic noise from cutting spindle motors.
Relay outputs: onboard relays handle fan cooling and fault alarm output for the workshop floor.
High-current terminal blocks: accept mains input directly.

Applications

Heavy-duty cutting machines for metal processing workshops
Controller replacements for machines that trip under high load
Machines with fixed cabinet space and unstable workshop power

One-Stop Service and Customization

Machinery builders work within fixed cabinet space, unstable workshop power, and repeated heavy-load operation. We design the layout around those limits, including your existing machine enclosure. In-house, we run a continuous 72-hour full-load burn-in that simulates the frequent start-stop cycles of a real cutting workshop, and every finished unit undergoes insulation resistance and high-voltage withstand testing before shipment. After our customer fitted this controller to their cutting machines, unexpected shutdown incidents at end-user workshops dropped.

FAQs

What problems does this board address in cutting machines?

It was built for a controller that often tripped under high-load cutting and randomly stopped due to interference from nearby motor drives.

Can the board fit our existing machine enclosure?

Yes. For this project, we reworked the layout to fit the customer's existing enclosure. Send us your drawing or the original controller, and we will match it.

How are the boards tested?

We run a 72-hour full-load burn-in in-house, and every finished unit passes insulation-resistance and high-voltage withstand testing before shipment.

What communication interface does it have?

It has an RJ45 Ethernet port for on-site debugging.
