Description:

Welcome                             To My UNIMAT  Site          UNIMAT / BELTS / MANUALS / ACCESSORIES            As a fellow UNIMAT user this site is maintained as a service to the    UNIMAT community. You will find information and parts for the    UNIMAT  DB200 SL1000  and UNIMAT 3 Hi,  I m Doug Feistamel from the Chicago areaThe Unimat DB/Sl model was first introduced here ( North America ) in the mid 1950 s by Emco .This precision miniature  Table Top Machining Lahte/Mill was made in Austria and sold world wide in the hundreds of thousands until production ceased in 1977. It s replacement the Unimat-3 was made between 1976 and 1990. These wonderful little machines are now orphans since Emco discontinued support of accessories, parts and manuals. The uses of these machines are as unlimited as the skill and imagination of the operator given the wealth of accessories available. There is resurgent  interest in the Unimat here in the U.S. and the secondary market reflects that, as prices for machines and accessories are on the rise.   Machines are brought down from storage shelves, rescued from  boxes in the basement, bought at flea markets, they trade hands on  the Internet and are brought back to life as new generations discover   the enjoyment their fathers found working with their hands . These machines have gone through some changes during the length  of  production, I will go over them briefly as they are documented on   other sites. The  machines have not changed in  basic design or overall appearance. The first DB s were cast iron and painted  hammertone  silver with two styles of motors, the early one was silver with a switch at  the bottom, the later motor was a gray/black Dutch manufacture motor,  with  hand wheels more detailed with waisted handles.The later production   DB s/ SL s were of cast aluminum-zink ( white metal ) and painted hammertone green, the  handles on the hand wheels were now a straight taper, there was a change   in the mill mast and socket design. The early units in this production had a  green metal cased motor with exposed brush access.The next change, that came   sometime in the 70 s, was the U-100 motor of gray plastic with an orange built-in slide switch, this motor was internally fan cooled and continuously rated ( probably their best motor ). In the final years of production the green steel cased motor returned and the hand wheels were now made of plastic. From what I have read, I believe over 400,000 units were produced. Please keep in mind that: these features overlapped in production cycles, I am not a Unimat expert,  any Unimat  information, additions or corrections that you would like to share I would gladly post here.          Note: In General the Unimat  DB, DB200, SL, SL1000 parts access. are interchangeable.  UNIMAT  BELTS   PARTS ORDER  PAGEThe first Unimat I bought ( about 25 years ago ) had no belts. The fellow I bought it from assured me they were easy to find, maybe forty years ago this was true. I tried O rings. I tried belts. I made them. I bought them. I still wasn t happy with them. I finally teamed up with a belting manufacturer and I am now able to offer the best fitting belts ever to ride the pulleys of a Unimat!      Please have a look at these other pages of interest on my  Unimat web site Here is something of interest from my belt specifications:The tension is a percentage of the pitch length and is in the middle of the recommended range.The belt is not glue bonded but rather, heat welded and is as strong as the belt material itself.The belts are sized not only for low and medium speed operation, but also to allow for the forces placed upon them at higher speeds.Although the material has a memory, the belts will stretch a little after 20 or 30 minutes of use.This material has a very high coefficient of friction and will not have a problem  transmitting power for this application.Of all the elastometers available for power transmission, this material (polyurethane) is the best suited and most widely used.These are self-tensioning belts, as no mechanical adjustment is provided, therefore the initial length is important.You are visitor #This page was last updated on: December 1, 2020UNIMAT  TECH  TIPS  PAGEUNIMAT  LINKS  PAGEFor questions.

This prevented  these parts from damage. The lead screw is made of mild steel, when hand wheels are knocked in transit, the end of screw is bent causing  the wheel to wobble.If you are purchasing  a machine, request that the seller remove  and pack these items separately. It will save  a lot of grief later.Order formUNIMAT  DB/Sl Parts ORDER FORMUNIMAT -3 Parts ORDER FORMBearing Specials!  NOWOrder formBELTS IN  STOCKPrices good for 2020 Celebrating 21 Years of providing the best belts to ever ride the pulleys of Unimat DB/SL and Unimat-3UNIMAT-3 Mill head  service updatedU-90 Motor      Ball Bearing Replacement Kit     In Stockemail Doug  dfeistamel@comcast.netWebsite Designed at Homestead Get a Website and List Your Business
