For over 50 years, accuracy and precision are what we are known for. Specifically, the accuracy of our flat honing machines holding a tolerance of plus or minus one micron. In addition to our precision machines, we have the latest technology in our metrology lab to test your parts for data analysis of finished workpieces. Whether your finishing applications consist of using super abrasive wheels, cast iron lapping plates or anything in between; inquire with the true experts in finishing. We are here to help improve your next project one piece at a time… 

Some of the most common types of materials we specialize in but not limited to are:

Metals

Our precision equipment creates superb finishes for metal materials. Generally speaking, metals are substances with the properties of high electrical and thermal conductivity. In addition to being classified as malleable, ductile and high reflectivity of light. In order for us to develop the best process and cutting tool recommendations, we analyze the elements that were formed together that’s created a specif type of metal. By doing so, it helps create you the most successful finish. As there is an endless amount of different types of metals, below are some of what we finish on our machines.

Carbon Steel – Alloy Steel – Stainless Steel – Cast Iron – Wrought Iron
Aluminum – Brass – Bronze – Titanium – Inconel

Ceramics

Ceramic materials can be tricky during the developmental phase of a process. While they are long-lasting and hard-wearing material they are extremely fragile in incidences of mechanical or thermal shock. Furthermore, ceramic materials are brittle, strong in compression, and weak in shearing and tension. Ceramic materials are nonmetallic and inorganic solids which make them unreactive to other chemicals when in contact. Our machines are so precise they have the capability to complete the process of removing ceramic surfaces. While using grinding wheels for flat honing processes or lapping plates using a cutting agent on our lapping machines can exceed requirements. Particularly, below are some of the different types of ceramics we commonly complete on our precision machines.

Alumina – Aluminum Nitride – Boron Nitride – Cordierite – Corning Pyrex Lava Grade A – Macor – Mullite – Quartz – Sapphire – Silicon – Silicon Carbide – Silicon Nitrite – Steatite L-5 – Tool Steel – Zirconia – Tungsten Carbide

Plastics

Similarly like other materials, there are many different types of plastics as well. Plastics are from natural materials such as cellulose, coal, natural gas, salt, and crude oil through a polymerization or polycondensation process. During both processes, the petroleum distillates combining with specific catalysts to create molecules needed to reach the finished form. In general, the uniqueness of the plastic industry is the range of refined hydrocarbon distillates. It’s known collectively as naphtha and used as a key contributor in the manufacturing process for plastic polymers.

Thermoplastics: Acrylic (PMMA) – Acrylonitrile butadiene styrene (ABS) Polyamide (PA) Polylactic acid (PLA) – Polycarbonate (PC) – Polyether ether ketone (PEEK) – Polyethylene (PE) – Polypropylene (PP) – Polyvinyl chloride (PVC)

Thermosetting: Cyanate ester – Epoxy – Polyester – Polyurethane – Silicone Vulcanized rubber

Optical Flats

The variety of glass widely differs in chemical composition and in physical qualities, but both mostly pass through a vicious stage in cooling from a state of fluidity. This material is a heavy and durable piece of glass. It commonly identifies by its brilliance, clarity, and high refractive quality. Optical Flats are a piece of glass that has been precision polished to a specific flatness requirement on one or both sides. They can be a reference to use for the purpose of comparing an unknown flatness surface. Moreover, double-sided polished optical flats are excellent in measuring the wavelengths of light or demanding interferometry requirements. At Stahli USA, our lapping and polishing machines are capable of achieving the expectations in flatness for the optical flat to perform successfully.
