Mill roundings

With a router, you can do a lot of creative work. Among other things, the making of curves. How to mill a rounding, we have summarized below for you.

You need this for milling rounding

With milling cutters, you can not only mill straight grooves or profiles and half profiles. You can also mill curves with a router. The momentum is possible. You will need the following components:

  • the router
  • a copy ring (copy sleeve)
  • a suitable cutter
  • a milling template

Information about the milling template

You can make the milling template yourself or you can purchase various templates from specialist retailers. With the cutter, you need to know which types of cutters you need or want to use - for example, a common groove cutter, a profile cutter or a V-groove cutter.

Note that when creating the milling template, you will need the diameter of the milling cutter and the distance between the milling sleeve and the milling ring.

Milling the rounding

Now place a work board under which you do not mill into your workbench. Then the workpiece is placed with the template. If you want to create a rounding on both sides, for example on the support leg for a stool or stool, clamp the template and the workpiece in screw clamps so that you can first work with the milling machine on one side. You must be able to pull the tiller accordingly.

If you want to mill the rounding on both sides

For two-sided milling of curves, draw the curves of the template onto the workpiece below. Because after milling the first rounding you have to clamp the screw clamps. The lines then serve as guides to help you clamp the template in the correct position. Otherwise, it may happen that the template slips and then both curves on the front sides are not symmetrical.

Mill the rounding in two working steps

You now mill the rounding in two passes. For the first operation, choose a low insertion depth for the milling cutter. A few millimeters are completely sufficient. Pull the router along the template by always pressing the copier sleeve firmly against it. At the same time, of course, you must also do the feed motion of the router. For the first few times, both together can be a bit difficult. But after a short time you are well trained.

In the second operation, you mill the workpiece completely. Then loosen the screw clamps, clamp the template over and carry out both work steps on the other end side (of course only if you want to mill on both sides).

Tips & Tricks

In this way you can also mill figures or letters. However, you can also work without a template and with other aids, which may also be suitable for milling rounding.
