In the past, Mecha outsourced any type of laser engraving requirement. We recently purchased a Trotec Speedy 360 to bring that process in-house. This has allowed us to shorten our lead-times reduce costs, and control quality better than ever with associated parts. We’re finding all kinds of other uses for the laser as well. It…

Mecha added a new CMM recently. The Keyence KM-T1200 uses a touch probe system with software that makes it really easy to set up a new program. Once the program is completed, the operator simply follows the on-screen photos that show where to touch the part for a measurement. This addition to Mecha’s inspection arsenal…

Mecha supports various government contractors in the production of parts for major defense and aerospace programs, with many DPAS-rated projects currently in the works. We are also a supplier to the medical, food, and transportation industries. As such, we are considered part of the Essential Critical Infrastructure of the United States and must remain working…

Machining can be very dangerous. Sometimes parts can be ripped out of a vise during drilling or milling, causing significant damage. This is why CNC machines typically have safety glass on the front doors, and most newer machines by will not run with the doors open. At Mecha, we mill parts as aggressively as possible,…

The dimensions on almost all drawings for machined components are assumed to be after plating. However, plating thicknesses generally only matter when machining parts with tight tolerances (<0.001″). Most plating processes only add a couple tenths or less (<0.0002″) of thickness per side. This includes chromate conversion, Type II anodizing, and electroless nickel plating. Measuring…

This is a bit of an oversimplification, but when a part gets anodized, the anodize layer forms halfway into and halfway above the original surface. So if a drawing calls for 0.002″ of anodizing, then the part will “grow” in size by 0.001″ per side of the part. For example, if a raw part is…

Deburring is the process of removing extraneous material leftover from machining. This material is not considered part of the design and cause a variety of issues if they come loose later. Issues may include plating voids, cosmetic paint imperfections, mechanical damage, or electrical shorts in some products. Burrs must be removed manually using various hand…

We’ve had this video in the “About Us” section for a while, but we thought it would be a good idea to highlight it here again to show one of our robots in action. We did all the machine integration ourselves, including the automatic door mechanism.

Mecha specializes in making custom chassis for rugged computer systems. This part requires a lot of 5-axis milling and tolerances of better than +/-0.003″. It will plated and painted to MIL specifications.

We make a lot of aluminum and copper heatsinks. Some of the parts take hours to machine, like these examples.
