Top China CNC Milling Services

CNC milling is used to apply a machined surface finish on plastic or metal or for creating complex 3D shapes. Looking something like a drill press, a milling machine uses a cutting tool that moves in all three dimensions, removing material to achieve the desired part shape , A block of material is placed on a moving table below the cutter. While the cutting tool turns, a computer controls the vertical (Z axis) motion of the cutter and the horizontal (X and Y axis) motion of the block of material

We’ve used PTJ Shop sporadically over the course of 10 years and have never had major issue with them. They’re always timely and responsive.
