The right hand side of the head shows the two leaf-type handle on the Z-axis gib lock. Pretty cheap stuff here. The degree ruler is common to any of the Chinese machines (even the Taiwanese) - good for ballparking. A true tramming will get things right.

2017-01-08· I had to add a quill and z-axis DRO to make the machine really usable. Its a good size machine with plenty of travel in all three axis' and it has enough mass to be quite rigid in steel. IMHO, if you are looking at benchtop mills, I think a knee mill is still one step higher that a dovetail-column mill because the z-axis accuracy is increased. My experience with adjusting depth by bringing the ...
Milling cutters are held in the spindle and rotate on its axis. The spindle can generally be extended (or the table can be raised/lowered, giving the same effect), allowing plunge cuts and drilling. There are two subcategories of vertical mills: the bedmill and the turret mill.

R. G. Sparber September 26, 2015 Page 4 of 24 Terminology The Y leadscrew can move in six different ways relative to the take up nut. • Rotation around the Z axis - this is called yaw.
A great website is Alan Pinkus's site which shows a method of mounting similar devices on the Z axis of an RF-25 type mill, which is the idea I'll follow. Fig. 2 Starting with the Z axis, the parts needed to mount the DRO are above.
Next, I assembled the X, Y, and Z axis anti-backlash ball nut subassemblies. The original screws were ACME with 8TPI. I got rid of those in favor of anti-backlash ball screws and nuts. The following pictures depict assembly steps for one of the ball nuts and screw subassemblies.
For the Y axis mounting for the ballscrew, I decided to use a FK15 standard flanged ballscrew mount. I chose to drill 6 M5 holes (to tap to M6) in the front of the mill casting to support an aluminium plate with an FK15 cutout (to make later!)
These motor mount plates and blocks allow a Nema 34 motor and 2505 ballscrew to move the z axis on a "45" clone benchtop mill
To make them fit the mill Z-axis saddle you have to grind off the corners a little bit. 3″ bolts are also a tad too long. With the bolts in the saddle I measure that I needed to shorten the bolts about 5/8″ for a comfortable clearance. That would mean that 2 1/2″ bolts might have worked out okay.
The final Z axis design. It worked out to be 1265 pulses per mm when driving the servo with a 2.6: 1 ratio on the timing belt pulleys. I opted for the strange number of 2.6: 1 because that was the highest ratio with the appropriate kilo-watt load rating that would not have the big pulley hanging out past the column of the mill.

2013-11-04· Just finished hooking up the Z-axis, and it's working beautifully! I'm absolutely thrilled that the DRO is repeating back to three decimal places of a millimeter.
2009-06-25· Power feed for mill Z axis Post by jclem40c » Wed Jun 24, 2009 9:58 pm Seems like I remember reading something about adapting a Horrible Freight power feed to the table on a millrite milling machine.
Motor Controls. I built a 4-axis motor control system using a pair of Applied Motion 2035XD stepper drives that I found at a surplus auction a few years back, and DIN rail mounted 24VDC power supplies housed in a repurposed rack-mount PC case.
There is the Z-axis way cover in place… And there is the Y-Axis way cover. You can see some of the mess these covers are designed to deflect away from the sensitive areas of the ways and ballscrews!
