Welcome to Mini-mill.com, your information resource for the
small, low-cost millng machines for home workshop use. The site is intended
primarily to help new and prospective owners to evaluate, set up, maintain and operate
these tools. This is a companion site to www.mini-lathe.com
which provides similar information for the mini-lathes.
In addition to several versions of the mini-mill, over the
years since I began this site in 2002, I have had the opportunity to use and evaluate
several other Sieg mid-size mills and related accessories. Check the Reviews page for lots
While these machines are small in size, with proper
adjustment and techniques they can make a wide range of very useful and reasonably precise
components that would be difficult or impossible to make by any other means. The mill is
an excellent compliment to a lathe, for making things that cannot be made on a lathe.
Because lathes are capable mainly of making shapes based on cylinders, a mill is needed
for making other parts that are based on cubical shapes rather than cylindrical shapes.
With a lathe and a mill together, you can make just about anything you might need in the
way of small precision parts. Neither machine though, is very good at making free-form
If you are a model maker, experimenter or someone who needs
to fabricate parts to supplement another hobby such as astronomy or RC car racing, you
will find the mini-mill to be a welcome addition to your shop.
Variations of these machines are currently sold by Harbor
Freight, Grizzly and Micro-Mark. Homier, has indicated that they may offer them in the
future. They are priced at around $500-$600 in most cases, but shipping costs and
accessories included vary by vendor. You can compare the various models on the Versions
If you are not famililar with milling machines and
operations, check out the Introduction
page. On the Features
page you will find a detailed description of the Grizzly mini-mill, most of which also
pertains to the models sold by the other vendors. On the Setup page you will find
information on setting up the mill for initial operation. Be sure the read the
Safety page for important safety tips.
These mini-mills have a lot of potential but also have some
shortcomings that you should be aware of before you decide to buy one - see the Features page for more information. The 7x10 interest group, began as a
discussion forum for the mini-lathe, but there is also much discussion, support and
project information related to the mini-mill. This group is made up of a very knowledgable
and experienced group of guys (and one outstanding craftswoman) who are always ready to
welcome and help newcomers. Check the Home Shops
and Mini-Mill links on my Links page and you will
find lots of great tips from other mini mill owners.
