Parts
The Onsrud "copy router" is a cost-effective alternative to conventional routers. The area of application is aimed at the entire field of copy routing, e.g. in the production of wooden toys, wooden goods, loudspeaker boxes, musical instruments or the production of molded parts made of acrylic glass.
Many additional applications, such as profiling edges on a table fence with inexpensive end mills, result in a flexible multi-purpose machine.
In contrast to conventional routers, the material is milled from below and the template is scanned from above. Simple production of templates, precise and above all safe working are the advantages resulting from the following functional features:
- The cutter processes the workpiece from below: lower risk of accidents and significantly reduced noise pollution.
- The template and the copying pin are at the top: The machine operator can see the template path, which makes tracking much easier. Plunge-cutting for internal routing is also unproblematic.
- The workpiece is positioned between the template and the machine table: This prevents vibrations and bending of workpieces. The milling depth is therefore maintained precisely and clamping of the workpieces is made easier.
- Largely dust-free working: The chips fall downwards where they are effectively extracted: This significantly reduces the risk of eye injuries caused by flying chips, for example.
- The milling spindle is mounted stably in the machine stand and not on a cantilevered guide arm: The advantage is particularly low-vibration running of the milling cutter and a high-quality milling pattern.
- Construction holes can be drilled at the same time as the parts are milled in one clamping operation.
The exemplary work safety and ease of operation also make these machines very popular in workshops for the disabled.
The machines of the 36210 series with a milling motor of 10 HP are Onsrud's top class:
The spindle (rated speed: 30,000 rpm) is made from a special steel alloy, and is fitted with precision bearings.
The spindle stroke is pneumatically adjustable from up to 76 mm. An infinitely adjustable depth stop in a convenient position ensures simple and precise adjustment.

The stable machine table with additional acrylic surface absorbs milling vibrations without scratching the workpiece. The scope of delivery includes a comprehensive range of accessories with tools, copying fingers and collets.
The vacuum principle can also be used for workpiece clamping with the templates.
