Mazak Laser Consumables
Mazak machines sit outside the D28 / M11 mainstream: the fiber heads take a small-body nozzle with an M5 thread, so a generic “fiber nozzle” ordered by diameter alone will not fit. This page covers what to measure and what we supply.
Why Mazak parts are a separate line
Most fiber cutting heads in the field share one ecosystem: a D28 body, an M11 nozzle thread and a 28–32 mm ceramic ring. Mazak's fiber heads are not in that group. Parts listings for Optiplex fiber machines quote a small body of roughly D10.5 × H12 with an M5 thread — an order of magnitude smaller in thread size than the D28 ecosystem.
That figure is the one parts listings most often quote for Optiplex fiber heads, not a specification we assert for every build. Before ordering, measure the old nozzle: outer diameter, height, and the thread on the body. Three numbers and a photo settle it.
| Measure | How | What it rules out |
|---|---|---|
| Body diameter | Caliper across the nozzle body, not the tip | D28 / D32 parts from the mainstream ecosystem |
| Height | From the seating face to the tip | Same-diameter parts from another head family |
| Thread | Compare against a known M5 or M11 nut | Wrong-thread orders, which arrive and cannot be used |
| Gas holes / layer type | Look into the bore | Single vs double layer mismatch |
What we supply
| Part | Range | Decided by |
|---|---|---|
| Nozzles | Small-body copper nozzles for Mazak fiber heads, single and double layer | Body diameter, height, thread, bore |
| Protective windows | Round windows by diameter and thickness, power-rated | Diameter, thickness, holder type |
| Focus and collimating lenses | Focal lengths to match the head | Focal length on the lens, coating |
| Ceramic parts, seals | Matching insulators and seals where the head uses them | Head revision |
Where Mazak orders usually go wrong
- Buying by diameter only. Two nozzles can both be “10.5 mm” and still differ in height and thread. All three numbers matter.
- Assuming fiber and CO2 parts cross over. A CO2 machine and a fiber machine from the same builder use different heads and different optics. The model plate tells you which machine you have.
- Replacing the window without checking the gas path. A window that hazes within a shift is usually a pressure or contamination problem, not a bad batch of windows.
Ordering
- Photo of the old nozzle on a rule, plus a caliper reading of the thread if you can.
- Machine model from the plate (for example Optiplex 3015 or 4020).
- We confirm the size against the photo before quoting.
- Wholesale and OEM packaging available for distributors.
FAQ
Do you sell Mazak original parts?
No. We supply aftermarket consumables matched to the measured part. For original parts, your Mazak service channel is the right route; the Mazak name is used here only to describe compatibility.
Is the Mazak fiber nozzle the same as the CO2 one?
No. They are different heads with different optics and different nozzle seats. Ordering against the machine model alone is how the wrong one arrives.
