    We sourced CNC turning knobs for professional audio mixers. The knurled surface is well-proportioned, easy for precise twisting. The color spraying finish looks premium. Every batch is inspected on ZEISS CMM to guarantee consistent inner hole size. No defective pieces found in incoming inspection. Good communication on drawing modification.
