Late Model Schaublin 102N Super-Presicion Lathe
Updated 15 March 2018
Schaublin lathes are known for their exceptional Swiss-Made quality and super precision. The company was originally started in 1915 and began by making tools for the Swiss watchmaking industry.
Although Schaublin subsequently introduced much larger machine tools and eventually CNC machines, the Schaublin plain-turning manual lathes, the model 70 and 102 are still in production and considered essential equipment by custom jewelers, custom watchmakers and other fine instrument makers.
Late model new-style (suffix -N) Schaublin 102N lathes were introduced in 1979. Examples built before the original Schaublin company was broken up and sold in the late 1990’s are highly sought after. They were fabricated and hand-fitted by the original Schaublin staff in a continuous tradition that goes back 75 years.
Similar to pre-1965 Fender guitars, pre 1990 new style “N” lathes, made only between 1979 and 1989 are generally considered to be better quality than machines built after the sale.
It is rare that a late-model Schaublin 102N is offered for sale in the U.S. When these machines do appear, they are often neglected, rusty, stripped of tooling and frequently missing parts. It is often said in Schaublin lathe enthusiast circles that one has to wait for an estate sale for a Schaublin lathe with tooling to be made available for sale.
This is a unique opportunity for the right person.

This lathe is in very good used condition. The bed shows typical wear from light/moderate use. Paint is original and in good condition. Bearing noise from headstock is low.
The machine is offered with a Morse Taper 2 tailstock (metric graduations) and your choice of inch or metric screw-operated carriage. A copy of the Schaublin service manual and parts diagrams are included with the machine.
Location and Moving:
The lathe is currently located in Burbank, CA 91506. I have a set of custom-built casters that can be securely attached to the cast iron base. Along with the large M24 eye bolts at each corner, two men can easily move the machine on a hard level surface.
The lathe’s location does not have a loading dock. Any lift gate truck with a lift capacity of 1500 lbs or greater can lift the machine. Due to the machine’s low center of gravity, unlike other engine lathes, it is not difficult to move it safely.
I have the following items of tooling which will be made available to the purchaser of the machine on a “first right of refusal” basis. All offers on the tooling will be refused until the lathe is sold.
It took over 10 years of diligent searching including two trips to Switzerland to put this tooling package together.
- Screw operated carriage (90mm stroke, additional either inch or metric)
- Star Wheel Drilling Tailstock: New Style “N” drilling tailstock, type 105-69.000 for W25 collets, metric graduation, wt 14.5kg [32 lb] – rare and highly sought after item.
- Steady rest with standard and ball bearing roller jaws
- W25 collets, metric, near-complete set 0.5 to 25mm, some collets are new
- W25 collets, inch fractional: 1/8, 1/4, 1/2, 5/8, 3/4, 7/8, 1″, some collets are new
- W25 collets, inch fractional 16th, 32nd and 64th, incomplete set (64th inch collets are now special-order only from Schaublin and cost over $300.- each)
