Tramming Shark

Postby weh385 » Sun May 19, 2019 10:51 am

I am new to the Shark in our club shop. It has been in use for a couple years. We have a standard water cooled spindle that came from New wave with the machine.

Everything seems to be in allignment and cuts square with the exception of the obvious tracks when doing cuts along the x axis as in the bottom of a pocket or a smoothing cut on the surface of a workpiece.

I understand what tramming is and basicaly how it is accomplished. However, I hesitate to attempt to put in shims without some help in the actual process.

Does anyone have diagrams, pictures, etc. of the procedure to accomplish this?

Thanks

Are you saying that your Z axis is not perpendicular to your table top and making some sort of saw tooth impression at the bottom after several passes with a end mill bit?

The process depends on how much it is out and what direction. You mentioned X axis.

How about some pictures and indicate the orientation of the piece.

The Z axis is out of square with the base of the table front to back. That, I believe is called the nod. It is making typical lines in the bottom of pocket cuts that go along the x axis. I know what needs to be done. I just need to find which screws/bolts/plates I must loosen and shim to accomplish the adjustment.

The tilt, on the other hand, is ok.

I would rather have some input from someone who has done this rather than just taking off things without a plan since the vendor has not provided us with any assembly documentation for this.
