Years before the advent of the CNC machine tool, there was the Bridgeport milling machine. If you were a machinist a generation or so ago, you likely worked in a machine shop that owned several of these iconic knee mills. They were popular in metalworking shops throughout the world and for good reasons. Although you. Read more

It sounds like your zazis limit switch is stuck on. If it is moving real slow it thinks it is on the decell switch because the switch is stuck in. I believe it is input and it should be a 1 if it is not on the decell dog. I cleaned out the Z limit switch, there was in fact a small piece of material wedged in the switch preventing it from ...

The shank is .2495 diameter so I lay it on the workpiece and bring the tool down to just below the height of the shank. I then roll the shank toward the tool while jogging up in " increments. When the tool clears the shank and you can roll the shank under the tool I just type .2495 into the Z DRO.

That has not been my experience. If I change tooling, the setting is lost anyway (since position relative to the tooling is what's important in Z axis). I installed a 3 axis DRO on my Bridgeport clone but haven't bothered to mount the Z axis; the knee dial does what I need and I've never had a use for the Z axis.

Sometimes it will, sometimes it won't it depends on the motor. With my set up, a 2:1 drive ratio would only produce 28% of the force a 1:1 ratio would produce at 40ipm. Optimal would be ratio which would give about 13% more force. I wanted to increase my machines performance on the zaxis but 13% isn't worth machining new pulleys.

What is a 6 Axis CNC Router? Every CNC router, mill, and lathe use axes which are essential to the manufacturing process. This is because the axes determine how both the tools and workpieces move during production. 3 axis CNC machines are the simplest and have X, Y, and Zaxis which move left to right, front to back, and up and down. 4 axis machines add an additional rotational axis, but a 5 ...
