Z Axis Gib Adjustment on Vertical CNC. I'm trying to figure out how to tighten/adjust the Z Axis Gibs on my vertical CNC Milling machine. I have a decent understanding of how Gib adjustment systems work on other machines, but this one is throwing me for a loop. It has 2 slides. Each slide has an upper and lower Gib making 4 Gibs in total for ...

If your time is worth anything, then it probably is an OK deal. If you got nothing but time, then it probably makes sense to "roll your own". I recall trying to figure out how to machine those "truncated pie-shaped" teeth, and then I realized, you probably don't need but 1/2 of them (if that) and they really didn't need to match exactly.

One type of CNC machining is 4-axis machining, which adds an additional rotary axis to the more commonly used 3-axis machines. 4-axis CNC machining allows for greater precision and versatility in the production of complex parts. The fourth axis, also known as the A-axis, enables the machine to rotate the part being worked on, allowing …

Machines such as the Bridgeport Boss, V2XT and DX32 series and others like Sharnoa, Wells Index, Shizouka, YCI YCM-40 and others are made for CNC knee mills and can often be had for less than the cost of a good manual knee mill. The advantage of a manual to CNC converstion is in retaining the manual control of the machine tool. Axis Motor …

Most Bridgeport Z axis ballscrew conversions such as the Elrod (shown in the Centroid link), Southwestern Industries etc have the ballscew hanging way out the front of the machine, to clear the original feed stop mechanism. This isn't ideal. However, you can actually fit a 16mm ballscrew where the threaded feed stop bar was originally fitted.

Y-Axis: Moves up and down (vertical). Z-Axis: Moves in and out, like drilling into a material. Advanced CNC machines, like those with five axes or six axes, have more movements: A-Axis: Rotates around the X-axis. B-Axis: Rotates around the Y-axis. C-Axis: Sometimes, there's a C-axis for rotation around the Z-axis.

When i turn on the machine and press home (all axis), Y and Z home fine, but X does not move and makes a grinding and whirring noise.

May as well get all my questions out there. Thirdly: my "Y" axis, I've had to adjust the max velocity down to 8 to keep the motors from "stalling"?

In CNC machining, the Z axis represents the vertical dimension of a machine's coordinate system. It governs the up-and-down movement of the cutting tool or workpiece during the machining process. As the tool descends or retracts along the Z axis, it determines the depth of cuts, the layers of material removed, and the precision of features ...

Once the computer program directs the CNC machine to use the work coordinate system, the Z axis will refer to the part coordinates. The Z axis has only two movements: up and down. In a work coordinate system, Z1.0 will position the Z one inch above the part. This is a safe space to send the Z axis or rather, the tool, before cutting begins.

A 5-axis CNC machine moves in five different directions: X, Y, Z simultaneously with A and B. X, Y, and Z are linear axes, while A and B are rotational axes. This type of CNC machine allows an operator to work from all different directions without having to manually reposition the part or the machine tools.

Or so is the story of backlash in CNC machining or machining in general. Backlash is the space between adjoining gear teeth. This space exists to allow the gear mesh without jamming. And to allow lubrication. So, the backlash is the solution to keep the machines from jamming. The more the amount of backlash, the less likely the machine …

The 3-axis CNC machine configuration is primarily found in CNC milling machines. In these machines, the workpiece is held in place by a vise. The vise, in turn, is fixed to a moving table. Designed to move, the table travels along the X and Y axes, while the drilling or milling tool travels along the Z axis.

Not moving any of the machine axis after calibration, I started the spindle to warm it up. The spindle ran for a short period then stopped with a "Z axis servo error" message on the crt. Thinking the Z axis had some how over traveled, I manually jogged the Z axis from the home position by hand.

The issue I am running into right now is that the Z axis makes a noise like a rapid clicking or grinding noise when it is going up the Z axis. If I apply some pressure and push on it this noise goes a way for the most part. When the Z is lowering it does not make any noise. I have tried loosening some of the bearings thinking this is the issue ...

It probably helps if your cursor jogging keys make the table move in the direction of the arrow, at least for X and Y. Pgup and Pgdn for Z up and down. If the keys don't suit your needs, just change them, and use arrows to make sense. It can be confusing if the left key moves the table to the right.

Every time you turn your CNC you will home the machine. First, the Z axis will travel upward, bump the Z Home Switch descend 5 mm and then slowly rise to trigger the home switch for a final time. Next, the Y Axis will travel until it triggers the Y Home Switch while simultaneously the X Axis will travel back until it triggers the X home switch.
