DATUM Machine LTD

Not every CNC job starts with a block of metal.

This time, a Wellington percussionist brought us an aluminium snare drum shell.

The job was to machine the snare beds with controlled depth and geometry, while working with an already-formed shell.

One-off parts welcome.

Ever wonder what actually happens before a part gets machined at DATUM? 🔧👀

A customer recently asked us to machine a brass star for a pathway - sounds simple, right?

They'd asked for Naval Brass, a material known for holding up well over time. But before jumping straight to the machine, we asked one question we always ask first: where and how will this actually be used?

That question opened up a bigger conversation. We looked at a few different brass options, thinking about how long each one would last, how easy it'd be to work with, and what actually made sense for a pathway. We also took a closer look at the design itself, since some edges needed a bit of extra care to keep things safe.

The job's still in progress - Zak's got a sample ready to go once the final opening is cut into the pathway.
It's a good reminder of something we care about at DATUM: precision isn't just about following instructions exactly. It's about understanding what a part is really for, then making exactly what's needed - not a gram more. ⚙️💪

Most people have heard of CNC machines. But what actually is a CNC gantry mill?

We've just published the first article in our new CNC Basics series - breaking down what a gantry mill is, how it works, and why manufacturers choose them for precision work.

No engineering degree required. Just a straight-up explanation from the team at DATUM.

Give it a read, and let us know what CNC topics you'd like us to cover next. 👇

What is a CNC Gantry Mill? | CNC Basics | DATUM Machines NZ A CNC gantry mill uses a bridge-style gantry to move a cutting spindle over a fixed workpiece. Learn how it works and how it differs from a CNC router.

RockPots will be on display at the NZ Bonsai Expo this October. 🌿
