Brass Nickel Plated Connection This brass connector is made with strong brass for durability. It's precisely shaped using advanced milling technology, making it easy to install. The nickel coating on the surface prevents rust and makes it look good, stopping the brass from tarnishing. Milling is when the workpiece remains relatively stationary and the tool moves along multiple axes. CNC milling machines have complex settings, including various axes and rotating tools, which can perform cutting operations from all angles. CNC Turning Parts Turning removes material from a rotating workpiece with a cutting tool. It is mainly used to process round bar materials. Metal Thread Handle The handle surface is treated with knurled. This anti-slip treatment creates a uniform concave and convex texture on the handle surface through a dedicated knurled tool, which enhances the grip feeling and anti-slip effect of the handle.
