An air-cooled 500W spindle motor, a speed governor with MACH3, and a 52mm mounting bracket are all included in the “CNC Spindle Kit 500W.” There are 13 screws and 10 ER11 screws included in the “CNC Spindle Kit 500W.” (free).
500W CNC Spindle motor: 100VDC, 500W, 110V AC inpu. Speed: At idle, it can go up to 12,000 revs per minute. It has a torque of 5000G/CM. It has an insulation resistance of more than 2 megaohms and a dielectric strength of 400V. The motor is 200mm long, and the spindle runs out 0.01-0.03.
Speed Power Switch: AC110V/220V, 50/60Hz, 50/60Hz. Output current at its peak: 6A. DC0-100V is the output voltage. Make sure there is no dramatic impact, no vibration, no explosion hazard medium, and there are no conductive metal particles in the area where you want to put it.
52mm Mount Bracket: This spindle motor bracket clamp is made of high-quality cast aluminum, which makes it strong and durable. It is 52mm wide. The diameter is 52mm, the length of the chuck portion is 45mm, and the diameter of the chuck portion is 16mm.
There are 13 pieces of the ER11 Collet Chuck. ER11 is a set of collets. One to seven millimeters is the range of grips (1mm,1.5mm,2mm,2.5mm,3mm,3.5mm,4mm,4.5mm,5mm,5.5mm,6mm,6.5mm,7mm). Tolerance for run-out is 0.01mm. All of the tools and equipment you need for your CNC milling machine.
It’s a good spindle for the price. A 2 HP router has been running on my CNC, which has made a lot of noise and used a lot of electricity. For a good price, I would have preferred a 1 hp air-cooled spindle with more power and a higher RPM. This one looks like a good starter machine. One-quarter as loud as a router at full speed and very quiet. Installation was easy, except that there was no wiring diagram or schematic with the unit. I had to go back online to figure out what went where. None of the bolts came with nuts or the right metric size or thread count to use them. The holes in the clamp are big enough for 1/4″ bolts.
I do most of my work with wood and have found that 500W is enough so far. I’m going to do some pocket work and see how true this is. Most of my work is done with a 1 to 1.5 mm bit for lettering and a 10-degree engraving bit for small details. I use these bits for everything.
In the end, I think this is a good value, works as advertised, and I hope the brushless motor will last a long time.
As I’ve used the spindle for some work, here are some more facts.
I like the spindle because it is a lot quieter than the 2 hp router that I had been using. However, I have some concerns and should have chosen a 1kw spindle instead of the 2 hp router. 1. It doesn’t look like it’s as strong as I thought. Under a lot of stress, the cutting bit would move about 1.6-2.0 mm. I had to cut the depth of cut and speed of the feed rate to make up for it. This is what I think is going on. The shaft below the motor housing may be bending.
