Review: Major upgrade - If youre like me and upgrading the spindle on your cnc, youll probably be recommended this a lot, and honestly theres a reason for that, the standard motor on the cnc is 7k RPM, this is 20K and so a major improvement, if you want to feel the full effects of that, this will need its own power supply as it takes a fair bit, but it can still be ran at speed without just having less torque to it, the nut and collet provided is alright quality but safe yourself the hastle and buy one of each individually, youre buying a spindle, not those parts and so may be slightly off and make noise, which is why Ive given it a 4/5 on accuracy, as the vibration from that makes it majorly louder, as well as the added speed of course, but still having this spindle at such a low price has made milling softer materials so so much easier and better, with it even milling aluminium at a push (this is all without its own power supply like I said). So overall this spindle will get your job done, and done well at that, it is still a budget spindle, but is a damn good one and I totally recommend it.
Review: Simple yet brilliant upgrade for standard 3018 machine. - This spindle is a great upgrade for a standard 3018 setup. No modifications are required to install it. I simply removed the stock unit and replaced it with this. I'm now able to cut twice as quickly. Very pleased with this purchase. Please note that this spindle is loud. But this is something you should expect as it's running at more than double the speed of the stock spindle.

## Features

- Spindle motor: new chrome plated DC brush motor; This spindle comes equipped with air-cooled function, which can work normally for a long time.
- Install this spindle set into your CNC machines, then your machines can easily engrave light metal or other hard to cut materials.
- Spindle uncirculation: 0.01-0.04; Speed: 3000-12000 rpm (12V-3000RPM, 24V-6000RPM, 36V-9000RPM, 48V-12000RPM)
- The output voltage is adjustable. The output current is not adjustable, and the output current is determined by the load.
- Note: If you want to use it on 3018 series CNC machines, you will need an additional 52mm diameter motor mount. The Genmitsu Aluminum Engine Mount for Z Axis (B08SC9K538) would be a good choice.

## Questions & Answers

**Q: Does this fit the 3018 prover?**
A: It requires you to 3D print a 52mm bracket. Ve sure to write Sainsmart for the bracket - it's a perfect fit and works with the end stops. Be *very* careful when removing the Z-axis bearings. They are 35mm bearings and are impossible to find. In fact, you should buy LM8SUU (short 17mm) bearings x 4 in case you mess up and some balls come out of the bearings. Those are easier to find. Print the bracket at least 80% solid, reassemble your machine, and you're in business. It works quite well.

**Q: does this work with the cnc3 3018 pro?**
A: Can you send me wiring directions to the board for this unit

**Q: Will this fit your new. 4040 model**
A: I had to purchase a new Z axis holder to use this spindle - it is not a take the old one out and put the new one in situation.

**Q: what do I use for a power source. do I just modify a wall plug cord to wire the converter?**
A: It comes with a 3-prong power cord which you connect to the terminal screws on the power supply. I attached crimp terminals to the ends of the power cord for a better connection.
