Pitch Polishing

Conventional Polishing for Spherical and Larger Surfaces

Pitch polishing also called conventional polishing or classical polishing is a more traditional and early polishing method. And it is more often to utilize this method of polishing for spherical or larger surface profiles as per clients’ needs.

High Accuracy and Fine Surface Quality

Pitch polishing may play better when it comes to satisfying the higher surface profile requirements. For the reason that this method takes more time to polish details. And it is known to offer ultra-high precision, superior quality, and high flexibility in optics manufacturing.

Fabricating Various Geometries and Dimensions

Pitch polishing could machine a wide array of shapes, structures, surface forms, and sizes. Our pitch polishing process is enhancing the appearance quality of any custom optics and makes them ready in the right state to go into the next step of machining.
