Pocket NC V2-10 Vs V2-50

The Pocket NC V2-10 and V2-50 are largely the same machine with the same work envelope, backlash, deflection, repeatability and speed of each axis. The difference is the spindle assembly.   V2-10 V2-50 Price $5000 $7250 Spindle Speed 2,000-10,000RPM 1,000-50,000 …

The Pocket NC V2-10 and V2-50 are largely the same machine with the same work envelope, backlash, deflection, repeatability and speed of each axis. The difference is the spindle assembly.

 V2-10V2-50
Price$5000$7250
Spindle Speed2,000-10,000RPM1,000-50,000 RPM
Tool DiametersUp to ¼” (6.35mm)Up to ⅛” (3.2mm)
ColletER-11CHB (⅛”, 3mm, 4mm)
Spindle Runout0.0005 in (12.7 µm)0.0001 in (2.5 µm)

The resolution, deflection and max speed of each axis may be the same on each machine but you can’t get the same rate of travel on each axis when cutting a materiel like steel, The higher spindle speed on the V2-50 will allow faster and smoother material removal, thus allowing you to increase the speed of each axis.

What are the different strengths of the V2-10 and V2-50?

See below a quick and concise breakdown of all the major differences.

V2-10

Pocket NC V2-10
  • If you are using a tool with a shank above 4mm and up to 6mm you may want to use a V2-10
  • Higher clamping force on tools over the V2-50 means tool pull out is less likely
  • The V2-10 uses a ER11 collet, this is a little cheaper then the V2-50’s CHB collet however you may need more of them
  • Of course, the V2-10 is fractionally cheaper and also does not require a compressor, so if you are getting started on a budget and you don’t have a compressor, this may be the better option.

V2-50

Pocket NC V2-50
  • Narrow and deep machining (~0.5mm – 3mm depth machining)
  • Faster axis travel roughing and should be carried out at 25-30K RPM and 50K RPM with very small tools
  • Four times faster material removal rate roughing harder materials like aluminium, brass and delrin etc.
  • The lower spindle run-out results in smoother surface finish
  • Larger and faster deep cuts
  • Faster tool changes with revised spindle
  • Increase spindle stick out by 20mm, offering a huge advantage when using smaller tooling.

What Sort Of Compressor Does The V2-50 Require?

We recommend using a compressor that is capable of outputting 1 cubic foot per minute at 25 psi. See a suitable example here.

What Else Do I Need To Run the Machine

If you are ordering one of our Pocket NC V2-10 or V2-50 Bundles, you have everything that you need! One thing to bear in mind however is that you will have to program the machine to cut parts using Fusion 360 that comes with the machine. You can use other CAM software also like SolidCAM however.

If you are not ordering a bundle you will need to order tooling for the machine. The Pocket NC V2-10 uses an ER11 collet and the V-50 uses a CHB. You will need to ensure tooling you order fits each collet size, remember the V2-10 takes a tool up to 6.35mm diameter and the V2-50 will go up to 4mm.

Is Everything Else The Same?

Yes, the build volume is the same on each being 115.5mmx128.3mmx90.1mm. This along with the NEMA 17 motors for moving each axis and the components other then the spindle all remain the same.

The tool setup therefore is a little different on each machine, the below videos do a great job of showing what is involved with each machine.
