Machining in Paarl since 2006
Lehmarsch, trading as Schafer Engineering, makes precision parts in metal and engineering plastic for factories, production lines and workshops. CNC and conventional machines under one roof, from a single replacement part to a full batch.
Most of what we make goes back into machines: a star wheel for a bottling line, a nozzle for a filler, a shaft for a gearbox, a guide that keeps product moving on a conveyor.
Customers come to us with a drawing, a CAD file, a sketch with measurements or simply the worn part in a bag. We work out the best way to make it, choose the material with you, and machine it on whichever of our CNC or conventional machines suits the job and the quantity.
Because routing, turning, milling and fabrication all happen in the same workshop, a part that needs several processes does not travel between suppliers. That keeps lead times short, keeps tolerances consistent from one operation to the next and gives you one person to talk to about the whole job.
The business our customers have known since 2006 now operates as Lehmarsch (Pty) Ltd, trading as Schafer Engineering. Same workshop in Triangle Park, same phone number, same email address, and the same careful work.
Six ways of turning raw stock into a finished part. Each has its own page with the detail: materials, typical parts, and when it is the right choice.
Fast, accurate cutting of flat and profiled parts from plastic sheet, aluminium and composite board. It is how we produce star wheels, guide rails, wear strips, gears and engraved machine labels for production lines.
Round parts made with repeatable accuracy: shafts, bushes, nozzles, adaptors and threaded components. CNC turning is the right choice when several parts must be identical, or when a profile is too complex to cut by hand.
Flat faces, pockets, slots, bores and hole patterns cut into plates, blocks and housings. Programmed milling holds the position of every feature against the drawing, so parts bolt together the way they were designed to.
Skilled manual lathe work for single parts, repairs and jobs where a machinist's judgement is quicker than writing a program. Ideal for replacing a worn shaft, re-cutting a thread or fitting a bush on the day.
Manual milling for keyways, slots, flats and modifications to existing parts. It is the practical route for one-off work, for squaring up stock, and for adjusting a component that has to fit an older machine.
Hygienic stainless equipment and complete assemblies, combining our machined parts with cut, bent and welded frames. Stands, trolleys, cleaning stations and machine sub-assemblies for food and beverage environments.
Two jobs from Triangle Park, what they are and how they were made. You will find many more on each service page.
A complex stainless steel housing with an offset bore, angled faces and threaded features. The blank was turned first to establish the main diameters, then milled in several set-ups, each one located from features already machined so that everything lines up on the finished part.
How we mill complex parts
A large plate with a stepped central pocket, counterbored holes, slots and an even facing pass across the back. Flatness and parallel faces were the priority, so the cut sequence was planned to stop the material moving as it was machined.
More about CNC millingWhen a line stops because a shaft has sheared, a bush has worn out or a guide has cracked, the part you need is rarely on a shelf.
Breakdown work is part of everyday life in our workshop. Bring in the broken part, or send photos and the main measurements, and we will tell you straight away how quickly we can make a replacement and what it will take.
Simple replacements are often fastest on a manual lathe or mill, with no programming time. If the part is likely to fail again, we can suggest a better material, such as stainless steel instead of mild steel in a wet area, or UHMW polyethylene instead of a harder plastic that cracks.
Two finished jobs: a four lobed stainless hub, and a set of stainless filler nozzles.
The hub began as solid round bar. It was turned to diameter and bored, then milled to cut the four lobes, the slotted mounting holes and the keyway. Turning and milling on the same job, in the same workshop, is what lets a part like this come out right first time.
The nozzles in the second clip were turned on CNC from stainless bar, with a flared mouth, a tapered body, sealing grooves and an internal thread. Once the program is proven, every nozzle in the set comes off the machine to the same dimensions, so any one of them can replace another on the filling machine.
Bottling and canning lines, food processing plants, packing halls, workshops and vehicles. The parts are different, but the need is the same: they have to fit, they have to last, and they are usually needed soon.
Every job follows the same route through the workshop, whether it is one bush or a batch of a hundred.
A drawing, CAD file, sketch with measurements or the worn part itself, plus the material and quantity you need.
We check the drawing, ask about anything unclear, choose the machining route and send a price with a lead time.
Stock is ordered or cut, fixtures are prepared and, for CNC work, the program is written and proven.
The part is routed, turned, milled or fabricated, often across more than one machine, in the same workshop.
Critical dimensions, threads and fits are measured against your drawing before the job is signed off.
Parts are cleaned, protected and packed, ready for you to collect from Triangle Park or for delivery.
Five stars from the customers who have reviewed us so far. If we have made something for you, we would value your review too.
“Great Business , very good in many Precision Engineerings, won't be disappointed.”
“Always deliver. Good solid business.”
Lehmarsch, trading as Schafer Engineering, is a machining workshop in Triangle Park, Paarl. We do CNC routing, CNC turning, CNC milling, conventional turning and milling, and stainless steel fabrication, working in stainless and mild steel, aluminium, brass and engineering plastics.
Yes. Schäfer Engineering cc now operates as Lehmarsch (Pty) Ltd, trading as Schafer Engineering. The workshop, telephone number and email address have not changed.
A drawing or CAD file is ideal. If you do not have one, photos of the part with the main measurements, or the worn part itself, are often enough to start. Tell us the material, the quantity and when you need it.
Our workshop is at 1, 5 Rectangle Street, Triangle Park, Paarl, 7646. We are open Monday to Thursday from 08:00 to 16:30 and on Friday from 08:00 to 15:15, and closed on weekends. Phone 021 862 0091 before you visit so the right person is available.
Send it through and we will look at the best way to make it, what it will cost and how long it will take. A clear drawing helps, but a photo with a few measurements is often enough to start.
