Lapping Services


The lapping machining process requires a variety of unique elements. Our team fully understands these safety steps and provides lapping machining that works for your needs. Each project is carefully planned, prepared, and executed to meet your part needs and to minimize any material waste that may cost you money.


Lapping is a Finishing Process Designed for Products That Require Very Accurate Specifications


Our lapping machining professionals understand the unique specifications that come with this process. We can work on parts between 0.15-inch and 18 inches in diameter. Our team is capable of parallelism of less than 0.0005-inch, which gives you the high-quality flatness and uniform style that you need to produce highly precise machined parts.

How Does Lapping Work?


Lapping machining works by suspending material in a carefully prepared oil and water mixture and using a rotating wheel to carefully remove material from the part. As the wheel turns, it pushes this loose abrasive against the material and helps form a uniformly ultra-flat part.

Our team carefully identifies how to prepare your part by checking your schematics, examining your part heat treat specifications, and carefully testing each produced part. We’ll then program our machines to start the lapping machining process to ensure that you get the parts your business needs.

Typically, we prefer using a water-based slurry in our manufacturing because it is less hazardous and safer for the environment. We strive to protect the environment by using the safest and most reliable machining processes, those that won’t cause any serious contamination or pollution in this beautiful region.
