Why Machining Matters
NADAF provides machining services in Melbourne for heavy equipment repairs and custom components, including line boring, metal turning and CNC plasma cutting. Our machining capabilities support worn components, replacement parts and equipment repair requirements.
Whether a component can be restored depends on its condition, so every job starts with understanding the part and the work it has to do.

Core Capabilities
Three processes, each suited to a different kind of component problem, from worn pivot bores to parts cut or turned from new.

Pivot points on earthmoving and heavy equipment carry constant load, and over time bores wear oversize, out of round or out of line. Line boring restores worn or damaged bores to suit the repair requirements, supporting correct alignment and accurate installation of replacement pins and bushes.

Lathe work for cylindrical parts, including shafts, pins, bushes, spacers and rollers. Components are turned to the dimensions each job requires, whether that means matching a worn original, replacing a part that’s difficult to source, or making a one-off to suit a particular repair.

Profile cutting from metal plate and sheet for brackets, guards, bases, mounting plates and custom shapes. CNC plasma cutting supports fabrication and equipment repair work by producing components to the required profile before welding, fitting or assembly.
How a Job Comes Together
Each job is shaped by the component and where it has to go. Whether it’s a line boring job or a single turned bush, the work follows the same practical order.
Look at the component, the wear or damage, and the equipment it belongs to, to understand what the repair needs to achieve.
Establish the dimensions to work to, taken from the original part, its mating components, a drawing or the repair requirement.
Bore, turn or cut using the process that suits the job, either restoring the worn area or producing the part new.
Check the finished part against its intended application, ready to go back into the equipment or on to fabrication.
Components & Applications
These are the kinds of components and repair tasks this work commonly involves. If your part isn’t listed, send through the details. Suitability depends on the component, its condition and what it needs to do.

Bringing existing components back into service.
Turned to suit the original or the repair.
Made new for a repair or fabrication job.
Part of a Larger Repair
Machining is often one stage of a bigger repair. Line boring usually goes together with pin and bush replacement, turned parts can form part of a hydraulic or plant repair, and plasma-cut components frequently go straight on to fabrication.
