(Machine Grinding, Fine Grinding, Lens Grinding, Ground Surfaces)

Grinding of your optical components can be achieved through a multitude of different manufacturing steps. Depending on which process is chosen to accomplish the ground surfaces you require the results received could be vastly different.

It’s an often misconception that you need to have the best lens grinder or lens grinding machine, but its not always just about the machine. It’s about the actual abrasive materials selected in which actually touch the surface of the part. The methods or machines can change, it often depends on the materials selected and the experience of the optician using them.

When grinding with a rough grit pad, loose abrasive, diamond wheel, diamond tiles, or any other form of abrasive there are many things to consider such as the hardness of your material vs the hardness of your abrasive, the remove rate, is the material heat sensitive, and so on.

Precision Machine Grinding

ULC’s precision machining occurs in what we call “The Service Center.” Here is where we machine all types of materials—and create all types of geometries! Our exhaustive equipment and focus on continual improvement means we are constantly investing in ourselves and our customers. We will help your blank design become a reality, be it cylindrical, flat, a prism, or in need of holes, channels or notches. Our machinists are striving to achieve different surface finishes, from rough grit to fine, ready to move to the next phase of its life cycle. Through the way our shop is laid out and capitalized, we strive to have the capacity to handle projects of any quantity. From single pieces to hundreds of thousands, from 4mm to 600mm in diameter. Whatever the raw material will allow, we will machine it. We are the go to grinding manufacturer.

Our blanks may not just be for polishers—do you need a light diffusion glass with a super fine finish? We can achieve very smooth roughness blanks to meet your precision lighting needs.

Because we hold such a large inventory of glass and equipment, along with a highly skilled staff of machinists and operators, we can get parts to you fast. Are you in a pinch on something and need blanks quick? Talk to us about our expedited manufacturing and < 1 week turn around. We have been proudly supporting the optics industry with blanks for over a century, and we strive to make you successful.

Pre-Polish Grinding

Our key to providing you with precision begins with our employees. Our highly trained opticians and operators are fine grinding surfaces in any quantity you need as either a pre-polishing step to ensue a smoother polishing process or for the purpose of providing the fine ground surfaces our customers require, which may not have otherwise been available with a standard blank.

Our cutting edge machinery and investment in technologies allows our operators to provide you with components up to 18 inches in diameter. Whether you require a fine ground surface or choose to take advantage of our additional polishing fabrication services we’ve got you covered. With polishing fabrication capabilities that can provide polished surface flatness to 1/20 wave P-V @ 632.8nm, with parallelism < 1 arc second, and surface roughness quality that can also be extremely low angstrom, we’re ready to help you out with your next project—so fill out the form below and ask us today.

Some of our customers require additional finishing, such as polished edges and bevels, and ULC has stepped up to the challenge, developing custom equipment and processes for keeping costs as low as possible for these types of projects. When we focus on continuous improvement, our customers win in the end.

Our newest capability includes our MRF finishing, a newer technology that involves polishing slurry being magnetically controlled in real time—the finished product meeting or exceeding specifications. Read more about the benefits of the Magneto-Rheological Finishing (MRF) process.

To ensure each product meets customer specifications, components are tested using state-of-the-art interferometers, polarimeters, autocollimators and many other optical gaging instruments where appropriate. Check out our quality information.
