Jig Grinding

[CHUCKY7796]

Has anyone Jig ground in a vertical mill. We just bought a Vulcanaire Jig grinder attachment. I have no previous jig grinding experiance. Im working on a mazak just using a boring cycle but getting bell mouth at the top. How can i keep the wheel from exiting the cylinder bore and make multiple passes? Any info would be useful.

 

Thanks.

Draw a line representing the path you want the tool to take. (hole centerline)

Then do a contour 3D and when you chain the line, choose partial, then chain it up and down as many times as you want. (partial chain, click top of line (chain points down), then click bottom of line, then top again, then bottom again.)

You could also check with your mastercam re-seller to see if they can implement a custom drill cycle into the post. Alternatively the Point toolpath may give you what you need and is very easy to use.
