Your Tight Tolerance Could be Seriously Affecting Part Cost [VIDEO]
It may be tempting to assume that a very tight tolerance should be your default choice. But, when they aren’t essential, it could increase your costs needlessly.

While CNC machining can produce an array of complex, precision metal components, there are some challenges to the process you need to be aware of.
Surface finish requirements are just some of the details critical to completing an RFQ that will help you optimize for manufacturability.
Unfortunately, consistent results aren’t always guaranteed. Learn what you can do to ensure calibrated measuring yields accurate results.
Surface flatness is an indicator of all points along a surface lying in the same plane, with the highest and lowest points within the flatness tolerance range.
To avoid the challenges of verifying OD/ID concentricity, try to use other applicable GD&T symbols in place of concentricity in tubing drawings and designs.
With these RFQ tips, you can not only speed up the quote process, but also ensure you get the part you want and a cost estimate that is as accurate as possible.
Eddy current testing is an important method of nondestructive testing. See what you may not have known about the process.
How do you qualify a new sourcing partner and ensure an efficient and problem free experience? Considering these points will help you make a decision you can feel confident about.
High precision internal grinding methods such as ID grinding and honing are used to achieve smooth finishes and tight tolerances on bore, hole, and tube IDs.
Double disk grinding provides dimensional accuracy for metal part applications that require tight tolerances, parallelism, flatness, and thickness control.
Precision flat lapping and other lapping techniques can be used for small parts requiring tight control of surface finish, flatness, thickness, and parallelism.
Surface finish requirements are among the details that are critical to creating a complete RFQ that will help to optimize for manufacturability.
Over time, we’ve developed a special appreciation for tungsten and what it can do. Learn some interesting facts you may not have known.
OD grinding is used to shape the external surface of objects between the centers and excels at removing circular defects and restoring or creating roundness.
What is lapping? In the right hands, this little-known process can produce parts with highly polished ends, tight length tolerances, and extraordinary flatness.
The centerless grinding process is ideal for finishing small cylindrical metal parts that require a tight tolerance and high-volume production. Learn some of the fundamentals of this process.
The electrochemical grinding process is a highly specialized method that combines surface grinding, chemistry, and fixturing, and has limited applications.
Electrochemical cutting (ECC) combines electrochemical erosion and grinding to produce a burr-free, shiny surface to a tight tolerance of ±0.005” (0.127 mm).
Thin-wheel abrasive cutting is an ideal method for high-volume 2-axis metal cutoff that requires precision, tight tolerances, no burrs, and a smooth end finish.
Cold sawing can do high-speed, burr-free cutoff of rods, tubes, and extrusions, but it is not ideal for very short lengths, smalls ODs/IDs, or hard metals.
