Welcome to Precise Lapping & Grinding Corp.

Lapping & Grinding of an Armiture for Zip Drive

Examples of our Work

Precise Lapping & Grinding Corp. (PLG) took on the challenge of finishing a zip drive armature for a customer in the electronics industry. Four competing lapping companies were passed over for the services of PLG due to our ability to hold pocket dimensions and the internal diameter of the hole

while meeting the customer's burr free and high tolerance requirements. Utilizing our state-of-the-art equipment including a Speedfam free abrasive lapping machine and Coil CNC grinder, the stainless-steel part was treated with lapping and grinding processes, achieving tolerances of 0.039, and ± 0.005". The part was further smoothed and cleaned with a deburring process.

This project has a high-volume production requirement, and we furnish 60,000 units weekly without fail. Parts are shipped to the customer in Singapore.

For more information about this armature grinding and lapping procedure or how PLG can excel in meeting you're demanding specifications please see the table below or contact us directly.
