2024 year model, 1.2 hp 900 Watt Servo Motor and 1 to 1 belt drive.
Upgrade for Mini Milling Machines with digital readout of spindle speed on controler

This build (what comes in the box image) is what you are buying contains. This kit has multiple improvements over the first 31 that I built to include the new 2024 controler.

Now comes with a 1 to 1 ratio; Motor 1 rotation to Spindle 1 rotation.

This allows the digital display/readout on the controler to match the actual speed
the spindle is turning +/- 2%. See video short (image 4) about spindle speeds.

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.
Achievable spindle high speed RPM from (factory claims 2.500 RPM)
With the 900 one to one drive:
Top speed is 3,300 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;
200 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.

HZ: 60

Torque: 11 N.M.

RPM: 200 to 3,500 estimated RPM in 10 RPM increments.
Note: Manufacturer recommended 300 to 3,500 RPMs
My personal testing results: This motor runs best between 200 and 3,300 RPMs.
A new 900 watt motor like the one seen here in photos. Its a little tricky to install on the mill and you will need long metric allen wrenches. Look at the images. Motor must be slid in while aligning the belt.

A new 2024 controler/driver like the one seen in photos.
This control unit is built by The Custom Crafter to include:

Thermal overload protection with reset.

E-Stop system with brake.

Power went out saftey program.

One latching button reverse on the fly.

Adjustable brake.

Adjustable soft start.

Programable fastest & slowest speed limits.

Speed ajusts in 10 RPM incraments.

One aluminum Spindle side timing pulley. Custom machined by the Custom Crafter to fit the spindle (see photos).

A new XXX/L050 1/2" wide timing belt. (Belt has been tested on test mill to insure corect fit with custom made parts)

The control computer (driver). Comes plug and play. Already programmed to optimal performance settings for mini milling machines.

Plastic plugs. Used to seal off spindle head after you remove the high/low gears and shaft.

On-Line access to programming instructions and fault codes.

Belt drive safety shield. Must be installed to prevent belt hitting you in the face should it break at high speeds.

Package will not include basic written assembly instructions yet. There will be a text number for direct assistance from the custom Crafter.

Milling machine seen in images is not included.
See assembly instruction video in this listing.
It is the last image, click on it. also make note, this is a 750 in the video.
That means top speed will be different.

Removal of high/low gear is not required but it is highly recomended.

You will be required to remove the power head and dissemble. This is not easy but it is required to remove the intermediate shaft and high/low gear. Plugs are provided to fill the bearing holes and keep internal components free of metal filings.

Instalation of kit can be done with or without removal of high/low gears.

The kit it's self is easy to install. A text number is provided for tech support.

This system has so much more power that it becomes tempting to see just how much you can cut in a single pass. Do not do this because the rest of the mini mill is not built strong/stable enough for this kind of abuse. If you jam it, you may damage the milling machine to include broken cutters, parts and the control unit. This is abuse and not warranty.

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