I bought a Sanou K27-80 independent 4 jaw chuck to use in a Kitagawa 3 jaw 10" to hold small die tools. The tooling has tight tolerances for concentricity & parallelism .0002" max, we are CBN hard turning and polishing. Not happy with the quality of the little chuck, its junky the Jaws are sloppy and raise a bit during tightening. I don't mind spend money, and don't have time to make it myself. Who is making a small high quality chuck & hard/soft jaws? Finished tools are being checked on a CMM.
