One of the key alignments on a vertical milling machine is setting the vertical head so that it is square with the milling table. This has to be so it is square in the x-z plane and in the y-z plane. All vertical heads, except on the smallest machines, are designed so that they can rotate in the x-z plane. This is a very useful feature.
Offset misalignment, sometimes referred to as parallel misalignment, is the distance between the shaft centers of rotation measured at the plane of power transmission. This is typically measured …

The joint holding the the container and electric screwdriver should be strong and able to hold the weight of the assembly. Put a little putty on the bolt first. Insert the bolt into the screwdriver's bit holder. Cover the whole joint with putty. The more putty the better the ball mill stays together. Ask Question
The most accurate way to check the alignment of the head is by tramming. This can be done by fitting a DTI to the spindle as shown. The rod can be any that fits the DTI. It can be fitted to the spindle using a drill chuck or any collet chuck. The accuracy of the chuck, in this case, is irrelevant. 92 tramming

A "square" result also is documented as to which side the tending side is, either to the wet end or dry end of the machine. Pi tape alignment A quick method to check roll-to roll-alignment is to use a Pi tape. Check distance around both rolls, on the tending and drive side. This gives you a relative difference. It does not show which roll to move.

Milling machine – aligning vices. In all cases of aligning a vice, what is aligned is always the fixed jaw. When this is aligned it stays aligned whereas the moving jaw can change depending on the workpiece. All of this assumes that the bottom of the space in the vice is parallel to the bottom of the base of the vice.
Optical alignment. Optical alignment is the measure of choice for rollers. For "square" measurements, the optical equipment is set up in line with the machine's main datum line. When checking for "square", measurements are taken on the tending and drive sides of the roll, at the 3:00 or 9:00 position of the roll face, whichever is easier to get at.
