Recently I acquired a Chinese made universal tool and cutter grinder. Machine is brand new and came with a lot of accessories which was why I got it. Finally got around to fully disassemble clean,debur,oil,and reassemble. Then the learning curve of how to setup and use. Which might take a lifetime
I mounted the centers on the table about 6" apart and tightened. Centers are built just like a typical tailstock. Base is keyed to the table. Slot on top base is slotted for upper tailstock piece which has a corresponding male with adjustment screws on each side to get adjust side to side and a lock screw. Once aligned tighten screw that holds to table should be done. Well my centers height did not align. They are .022 off. Wtf! I'm no expert but I would think they should be exact for precision. Whats baffling is matting surfaces of tailstock are all scrapped. So I decided to blue up the parts and see what they say.
Holy cow like said I'm no expert but maybe three or four contact points on a 3x4 base?? Top of base where tailstock slides on was barely touching and on the inside edge only barely. So I decided it would go through and make these centers align the best I can. My plan is to surface grind all the matting parts and then scrape as necessary. My main question is how to align the tailstock base to grind the bottom of base. When every surface is curved or uneven. The only way I have come up with is extending the quill on tailstock and take my measurements from there. The problem is that won't tell me if the base is tiled side to side. I planned on having the quill .0002 high when extended for deflection and wear. But I can figure out how to make sure the base is parrallel to the table. When measured each ear of base slides were different height and tilt. So how can I trust the bottom of the tailstock base. I tried putting a gauge block on surface and level with a .0001 gauge mounted to spindle then to the same to other surface and difference was maxing my gauge so I didn't trust that method of aligning.
So the question is how to check the tilt "side to side" of the base. Not the length of quill I think I've got that. Unless that's wrong too? Any input appreciated thanks.
