For our European Friends

I am looking at a drawing from a German Company and it states:
"General Tolerance DIN 7168-f"

The particular dimension I am interested in is .4mm.

Would someone...

Here is a shot that details the way I do it with my X2 yoke set-up. It shows detail of the ball screw ends.

Burn,
I installed the IMService 4 axis servo system on an X2 with ball screws for a customer. The machine ran great for the testing period I ran on it. I would say "don't hesitate, get the servo...

We herby retract the previous proposal for complete Super X3 machines set forth here. We will be concentrating on the conversion kits from Syil for the X3 mill.

With my converted X3, I once called a wrong TLO in a program and plunged a 3 flute 3/8" cobalt rougher into 6061 about .175" deep full width of the cutter. The machine then went along cutting at @...

Four axes integrated into a single board is a great concept, however, what happens if, God forbid, one axis goes down? Out comes the entire board and you are looking at a manual mill again until it...

The EAS boards are based upon the LMD18245 drivers. I have used the EAS boards in many different systems I have built. They work great within thier "no-frills" structure. By no-frills I mean lack of...

Lou,
What you descibe leads me to believe that either A) the running current is set too high or B)the steppers Syil chose just run hot.

I will be better informed once I receive those five kits...

Lou,
I am looking at Automation Direct's sure step documentation and it states "operating temperature range=-20 degreesC to 50 degreesC (motor case temperature should be kept below 100 degreesC(212...

Lou,
The steppers should not be getting extremely hot no matter what speed you are running. In all actuality, the faster a stepper is turning, the less current it draws due to the decreased time the...

Have a look at my site www (dot) kdntool (dot) com for the Xj-9510 converted to cnc. I will be introducing a kit soon. Still working on ball screws for it. It is far superior to the X2 in design.

Beware the Thompson ball nuts from McMaster Carr. A while back HomeshopCNC switched from Thompson over to Nook because the Thompson ball nuts were not machined correctly. The mounting threads were...

In that case you need a spring washer (bellville washer) in there to provide a constant spring force pre-load on the bearings while still maintaining rotational smoothness. Look at McMaster #94065K42...

That may be too much clearance between the washer ID and the journal OD. It may be allowing the washer to tilt to the side that does not have much contact face.(see blue face in attached .jpg) You...

How tight of a fit is the washer you made to the bearing journal of the ball screw? It should be a almost a line fit. Also look at the shoulder where the journal meets the ball grooves. Is the...

Per the Machinery's Handbook: material=6061, mill dia=.250, feed / tooth=.002, SFM for carbide=620.

Given your 4mm 2 flute end mill lets assume .001" feed/tooth.

Per Cimco Feed/Speed...

A bit more XJ-9510 eye candy. Notice the thickness at the base of the column and the amount of Z axis dovetail engagement. Also note the tapered gib on the Y axis pic as well as the scraping.

In order to stay with 120 VAC input, the VFD drives a 1/2 HP 56C frame motor. With a 220 VAC input, the sky's the limit.

I utilized the stock Z axis lead screw and drive it with a 3:1 pulley...

Here is a shot of the X3 I converted some 2 year ago.

The mill is nice for the price. The spindle drive motor looks like one of the "electric scooter" motors. The spindle spins smoothly due to the fine pitch gears it is driven by. Once I finish...
