Schaublin 102N Super Precision Swiss Lathe For Sale

Schaublin 102N
Schaublin 102N Lathe with 102-45.000 Screw Operated Carriage and 102-65.500 MT2 Tailstock

Late Model Schaublin 102N Super-Presicion Lathe

Updated 1 July 2018

NOTE: The Schaublin 102N has been SOLD

I have a mid 1970’s Schaublin 102 (pre-N version) with W25 Back Geared under-drive headstock, MT2 tailstock (inch) and an early 1980’s Screw-Operated Carriage (inch 3.54″ stroke).

This lathe can be mounted on a bench and driven from underneath by a VFD controlled motor. I am planning on setting this lathe up as a secondary operation machine, but I will consider offers. I also have some tooling (W25 collets, Tripan toolpost and holders) that can be packaged with this lathe.

I also have some W20 collets, inch and metric sizes, and W20 adapters (MT2-W20, etc) still available.

Please contact me via email if you are interested. 

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 by 1979. They are very similar in construction and function as the previous generation of Schaublin 102 but have a more angular design, which is still being used for Schaublin 102 lathes proceeded today.

Examples of the 102N lathes built before the original Schaublin company was broken up and sold in the late 1980’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 in the 10 year period 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, badly worn, 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.

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.

Upgrades

A GE/Fuji VFD drive unit is currently installed on the lathe allowing infinite variable speed control. The addition of the VFD drive upgrades the lathe to the functional equivalent of the 102N-CF version sold in the 2000’s. The VFD drive also gives much of the functionality of the back-gear speed reduction unit without the mechanical complexity and maintenance requirements.

The VFD drive is very useful for running the spindle at very low speeds. It is possible to go as low as 5 Hz drive frequency, which gives a minimum spindle speed of 25 rpm for  low torque applications such as grinding.  At a 10 Hz drive frequency the spindle runs at 50 rpm, matching the minimum speed of the 102N with the mechanical speed reduction unit.

  • GE FUJI AF 300 G11 Variable Frequency Drive (VFD), 2HP, 460V
  • GE branded version of FUJI Frenic G11 unit used by Schaublin to power accessory drive (for milling/grinding attachments, etc)
  • Variable Frequency Inverter Drive with flux vector and dynamic torque vector control (for smooth running at low speed)
  • LED and LCD display with keypad, with Keypad Extension Cable for mounting the display / keypad in  a convenient location.
  • Settings for Motor 1 and Motor 2 for use with the dual speed Schaublin motor.
  • Line reactor for motor winding protection
  • Custom installation with shielded conduit and 1000V insulated wire
