I believe that's a starting circuit for AC induction motors. Possibly but not necessarily related to a CNC application.

Possible uses for such a circuit:
1. Turning on/off a milling spindle
2....

The DC servo gets power from the drive, and the drive is wired to the DC power supply. Single or multiple power supplies can be used... it doesn't matter as long as sufficient power is provided.
...

Yes, you're correct. Admittedly I haven't worked with DC servos in a couple years, just steppers and AC servos.

As for the steppers, I've been working with G203Vs as of late. The COMMON on these...

Sorry, no pics at the moment, but I'll try to convey the message without using 100k words.

For March 2010, Glacern Machine Tools introduced the GSV-550 5" milling vise to fill the gap between our 4" and 6" vises.

The vise has a 5" jaw opening and is well suited for all sizes of...

Our rails will bolt directly to metric T-slot extrusions and can also bolt to fractional T-slot extrusions by drilling a few holes in the aluminum T-support.

Here's a project we worked on awhile back... a 7" OD x 5.5" ID tube with ID chucking. Due to the length, we used some fairly long soft jaws.

If the walls are sufficiently thick, regular jaws...

Use a piece of MDF/particleboard as a "backer board" and attach it to the back of your workpiece with flat head screws. Then screw or clamp the edges of the the backer board to your table.

Climb or conventional milling? Do you get the same results either way?

Also, try increasing your chipload. But instead of increasing the feedrate, keep the feedrate at 60IPM but lower the...

High speed machining encompasses a variety of techniques and concepts revolving around chip thinning. The idea is to take light cuts with fast feeds, rather than heavy cuts with slow feeds...

Hey Tony,

All round shaft linear bearings have recirculating ball bearings, unless they are bushings, in which case they have no ball bearings at all, just solid sliding material. With...

Yes they are in stock at $249.99 each. Please email us for shipping, thanks!

Grinding on a vertical mill can be done with a flaring cup wheel (typically used for tool/cutter grinders), kind of like a mini Blanchard. As long as the wheel is dressed with a diamond, the results...

There is typically no minimum C-axis feedrate. I'm not sure why the turning range on your machine is listed at 60-6000 RPM.

DZASTR is correct that full torque is developed at 0rpm. However, note...

The rails can be butted up, but not straight out of the box due to the light chamfer ground on the ends of the shafts. Some careful grinding will be necessary. Yes, we can supply longer lengths in...

Thanks for posting our link, Mike. It is much appreciated.

Also wanted to note that in addition to our 4" GSV-440 vise which debuted not to long ago, we will also have a 5" GSV-550 available in...

Chuck,

We'll be carrying our own brand. Our products are made to similar quality, tolerance, and load specs to those of the name brands, but will be priced much lower. Our ball bushings and...

Linear ball bushings with supported rails are our preference for shop built CNCs. That is why we'll be offering them on our web store later this month (around xmas time) with rail lengths from 13"...

Many of you have already seen these which were released on our site several days ago (http://www.glacern.com/videolounge).

As do we. It's the industry standard for automatic oilers in CNC machining centers. Shell Tonna 68 is similar.

However, I don't think changing the oil will help with the oil flying off. The...
