High-end audiophile power amplifier panel knobs have very strict requirements for the quality of CNC machining. This aluminum audio knob has dark lines and uniform stripes on the surface. It is processed on a cylindrical surface without any scratches or knife lines. After arriving at this CNC-machined aluminum audio knob, I can't bear to feel it directly with my hands.

There are still many difficulties in the process of CNC machining aluminum audio knobs. VMT tried many methods to do this well. Whether it is tools, machines, or various parameter settings in the CNC machining process, the requirements are very high. The premise is a rich experience.

We finally discussed with the equipment factory various CNC machining methods, and the aluminum audio knobs finally met the customer's requirements, which also enabled us to gain a lot of experience in this process.
