Delft Spline Systems offered

DESKTOP CNC MACHINING

Delft Spline Systems is a Dutch software house, founded in 1985, at that time specialized in the development and the use of CAD/CAM software for complex freeformed geometry. We started as spin-off of Delft University of Technology, releasing a CAD/CAM program called SipSurf. This was MS-Dos software offering Spline surfaces (NURBS), which explains the company name.

In 1995 we released a completely new program called DeskProto: Windows software for "Subtractive Rapid Prototyping", which has been our flagship product ever since. DeskProto offers "3D CNC machining for non-machinists". It reads CAD data from any CAD system, and exports NC files for any CNC milling machine.
In November 2026 all DeskProto activities have been transferred to Vectric Ltd in the UK. More information on www.deskproto.com.

In addition Delft Spline Systems used to be a reseller for two brands of desktop CNC milling machines: Isel (made in Germany) and Roland (made in Japan).
However, begin 2026 we stopped offering machines, as a first step toward retirement of the company owner.

We still have a stock of Isel spare parts and of the Kay control software for Isel machines; contact us via email when you are interested.
