  • New to me Belt Grinder :I Hope

    Been wanting a Belt Grinder for years but never seen anything that would fit my needs,I seen this style of Belt Sander made in Germany that can accommodate internal and contouring,debated for a long time.Well it arrived today and will need a few repairs as the drive wheels need to be recoated and possible a motor change.The motor is 440 volt and 2 speed,that is awkward for a VFD to handle if I understand correctly.I have a 1-1/2 hp 1ph TEFC motor setting idle that would do the job,this was the first one I’ve seen for sale in North America.

    Sorry TTT but it is not allowed for you to have that German built grinder in North America. You must send it to me right away or face severe consequences! Why do you think you never saw one before in North America!!! I am a nice guy so I would contribute to the shipping in order to keep your ass out of prison.

      TTT, what voltage and phase(s) do you have in your shop. Also, please post a pic of the actual motor nameplate. There may be options . If you go to your single phase motor I am assuming it is single speed and single phase is not really adaptable to variable speed...

      Went back and looked again... Is the pic of the nameplate the motor nameplate? It is confusing as it does not indicate two speed. I guess I just need more info in general.

          interesting looking unit. Will a C face type motor bolt up with or without an adaptor? Could the existing motor be rewound economically?

            Do you think Europeans look at North American equipment and ask "why can't they build something like this?".

              You can buy IEC mount motors in the USA to simply bolt on if you have any difficulty adapting NEMA style. If it is dual speed then likely dahlander wound and the 3400 rpm is the 1.1kw output. With your 1.5hp, assuming it's 2 pole you get similar output to the 2 speed motor at full and at 1/2 (30hz) Hz settings.

                  That looks like a pretty well built and handy machine. It looks open and easy enough to adapt any motor to it without much trouble.

                    Im sure there’s more of these in North America,you never see them for sale. Have you used the New VSM Abrasives Actirox Belts that they released in April of this year,they claim substantially better performance than there Ceramic Plus or the Cubitron Belts?Zimmerman used to built a Wood Milling Machine that looked like a Bridgeport but 50% heavier.

                    My Shop has 1ph only,according to skimpy info it’s 2 speed but I will investigate more today.

                    Yes they build high end machines,my friend bought one of there 24” Disc Grinder from a Old Pattern Maker.The Pattern Maker brought 2 New Machines from Germany in 1973 the Disc Grinder&Wood Lathe $36000 cdn.

                    Will have to make adapter plate,have some scrap aluminum laying around.Rewinding would not be a option cost wise.

                    No I think High Qaulity Machines can be made anywhere if Factory’s & Worker’s are qualified to do so,but quality cost big bucks.

                    I will try to get operational with what I have on hand to see if Machine Performs to my Expectations Hopefully 🙂

                      Very nice! I take it they must use some sort of gum rubber roller cover to drive against the abrasive side of the belt or???
                      I just need one more tool,just one!

                        Sorry my mistake, it’s a single speed motor.Does anyone build a VFD that can go 1ph to 440 volt3ph without a transformer?

                        Yes it appears very well built,be nice to leave Original motor but I will wait and see what VFD options are.

                        Yes the one one wheel has abrasive side on it,talked to Nexus Belt Grinder Guy and he has one configuration that does that with no issues.Machine is 1983 and all coating on Wheels has separated from Aluminum Wheel,will be dropping wheels off tomorrow to be recoated.The durometer will be a guessing game possible 70,I’m open to ideas on that.

                            Not knowing your kind of electricity in N America couldnt you just buy a single phase in 230v ,three phase out 380v vfd.? Isnt 380 close enough for it to work.?
