Internal Polishing in San Francisco CA

Improve all kinds of metal parts with our highly precise internal polishing in San Francisco CA

No matter which method may have been used to create a metal part--from EDM to laser sintering to casting--it is bound to have surface imperfections. These imperfections are especially troublesome when they affect internal passages. They can affect the flow rate of gas or liquid through the part, or even lead to premature stress failure in the case of EMD recast parts.

Should you just accept these problems?

Of course not.

Extrude Hone AFM’s internal polishing in San Francisco CA offers the ideal solution.
AFM ProcessWith abrasive flow machining, it is possible to enhance the surface finish of metal parts, without removing so much material that the blueprint specs of the geometry or the internal passages are compromised. Unlike hand tools, our process for internal polishing in San Francisco CA can reach deep into every passage, no matter how small and convoluted it may be. The end result is a uniform, consistent finish that will enhance the performance and durability of the part.

Here’s How Internal Polishing in San Francisco CA Works:

AFM ProcessAFM Process

  • We create a tool or holding fixture that will direct the abrasive flow to the areas of the part that require polishing.
  • We choose the appropriate grit for the job. Typically, for internal polishing in San Francisco CA (as opposed to aggressive surface removal) a fine grit is needed.
  • We mix the grit into a special polymer designed to carry it to every millimeter of the internal passages at the correct speed for polishing.
  • We load the abrasive-laden polymer into the workpiece, using a hydraulic ram to ensure that it passes through at the correct speed and pressure so that the desired amount of metal is removed from all contact surfaces.

This process is highly customizable and flexible, allowing for precise and predictable internal polishing in San Francisco CA. You can rely on our expert staff to help you select the right options for achieving the desired finish improvement on your part, whether you are working with a hard metal such as titanium or a softer one such as aluminum.
