Parts kept close to the benches in Spartan
Our Spartan base supports fibre laser cutting work that depends on clean optics, steady nozzle alignment and a head that tracks the sheet without drift. Sheet-metal shops in the East Rand, Johannesburg and Pretoria often collect parts here, while Durban, Cape Town and Rustenburg jobs are handled through planned dispatch and field visits where needed.
The stock range covers the wear items that usually move first on a cutting head. That includes single layer and double layer nozzles, focus lenses, collimator lenses, protective windows and ceramic rings, with matching parts selected to suit the head body and the cutting task.

Bench service for heads that need careful handling
When a head comes in for bench service, the work is done around the parts that matter most in cutting performance. Nozzle centring, focus setting checks, lens cleaning and protective window replacement are handled with the aim of keeping the beam path clean and the cut edge steadier on sheet material.
Crash damage inspections are common after a nozzle strike or a head drop, and the head seal may need rebuilding if dust or gas leakage has started to creep in. Capacitive sensor checks are part of the process where height sensing has become erratic, because a drifting sensor can upset pierce height and cut consistency.

On-site alignment across busy industrial areas
Some heads are easier to set properly at the machine, especially where the shop runs tight production windows or the machine cannot be moved. On-site head alignment is available in Johannesburg, Pretoria, Durban, Cape Town, Rustenburg and the wider East Rand, with attention on the machine table, head position and cutting behaviour during real production jobs.
Humidity near the coast can affect stored optics and seals, while inland workshops often deal with fine dust from grinding, cutting and handling sheet stock. That means cleaning routines and protective window checks matter just as much on site as they do on the bench, especially where stainless steel, mild steel and aluminium jobs are cut on the same machine.

What local sheet-metal shops usually ask us to cover
Spartan sits close to the industrial routes that feed fabrication plants, job shops and contract cutters in Kempton Park and the broader East Rand. Many of the calls we handle involve worn nozzles, damaged ceramic rings, cloudy protective windows or a head that no longer holds focus the way it should.
The service mix also suits shops that change material thickness through the day. A head that cuts light gauge sheet in the morning and heavier plate later on needs the optical path checked, the focus position verified and the gas path kept clean, otherwise the cut edge and piercing behaviour start to wander.
- Job shops running mixed sheet thicknesses
- Fabricators cutting stainless, mild steel and aluminium
- Contract cutters with high nozzle turnover
- Plants needing spare head preparation
Focus settings, cleaning routines and the small details that matter
Fibre laser heads respond badly to loose habits. A slightly dirty lens, a scratched protective window or a nozzle that is not centred can change the cut quality more than many operators expect, especially on fine detail work and tighter tolerance parts.
We cover the practical side of maintenance too: cleaning routines for lenses and windows, checks on the ceramic ring seat, and focus setting reviews where the head is not sitting on the right focal point for the job. It is ordinary workshop work, but it saves material when the cut starts to drift.

Getting parts or service arranged through Spartan
Enquiries for Spartan go through the contact page form, whether the need is for parts, bench service or an on-site alignment visit. The usual brief covers the head type, the wear item needed, the machine model if available and whether the job is for a shop visit or field work.
Inside the team, Marius Johannes van der Merwe oversees the branch direction, with Thandiwe Rapetswa coordinating operations and the technical team handling service and alignment work. Jaco Essop manages bench service, Lerato Tau takes field alignment jobs, Anele Daniels works on parts sales and Willem Pretorius leads technical support where the head condition needs a closer look.
