2024 year model, 1 hp Servo Motor Upgrade for Mini Milling Machines.
This is build # 4 Image number 1 (what comes in the box image) is what the actual kit you are buying contains. This kit has multiple improvements over the first 30 that I built to include
the new 2024 controler.

See assembly instruction video:

    Currently many parts are still hand made:
    Lead Time can be up to 5 days.

    That also means that if you lose a part, it will have to be hand made to fit your specific system as follows:
    • Drive belt is a standard size and in stock
    • Motor is standard and in stock.
    • Motor controller is custom made 2024 design.
      Usually I have 5+ finished but sometimes I am making more.
      You will be asked for information to find your previous purchase before we
      ship you replacment parts.
    • Motor drive pulley is mass produced now. We have plenty.
    • Motor mounting brackets + spindle lock are hand made.
      The new design is to allow CNC manufacture in the near future.
    • Spindle lock is hand made.
    • Spindle drive pulley is hand made, 5 in stock.
    • Belt cover shield is hand made.
    What I am saying is that if you lose the spindle lock or belt cover you will have to make your own to fit. Maybe I can make a replacement but only with reasonably accurate measurements.


    About the system:

    • Eliminates noisy and failure prone internal plastic H/L speed gear.
    • Control unit is placed above and and clear of the metal filings that all too often blow the main board. As seen in images. 
    • Runs extremely smooth and quiet.
    • Adds the reverse on the fly feature.
    • Adds the E-Stop feature.
    • Includes the power went out safty feature. This is a must for automated systems.
    • Increases achievable spindle high speed RPM from (factory claims 2.500 RPM) to 3,280 RPM. This is the actual result we measured on this system. Each new system is subject to individual results depending on the main board, power supply, programming and the milling machine it is installed on, etc.
    • Low speed achievable spindle speed:
      O.E.M. claims 100 RPM. My testing shows
      almost no torque at these speeds.
      Compared to our motor;
      RPM with 10 NM torque. You cannot stop it by hand, outstanding torque.
    • Increases hp from (factory claims 1/3 to 3/4 hp depending on model) to 1 HP and 10 NM meter torque.


    All milling machines are dangerous, increasing the horsepower increases this danger. 

    It is your responsibility to insure fit and proper application. We make no guarantee of safety, application or that this product is suitable for your intended use.

    Our liability is limited to the purchase price of this item.
