A profilometer checks surface roughness by tracing a stylus across a machined surface.
Surface finish is one of the most common callouts on turned-part drawings, but it is also one of the easiest to overuse. Read More
Thread gaging helps confirm that machined threads meet the print requirement before parts move through production or assembly.
Threaded features are one of those production details that does not always get attention until parts start failing inspection or assembly.
A tapped hole, outside thread, set screw hole, port, or small threaded feature may only take up one line on the drawing. But in repeat production, that one line can create scrap, rework, assembly problems, inspection delays, and supplier/customer disagreement if the callout is not clear. Read More
Tighter CNC turning tolerances often require more inspection time and closer dimensional control.
A tolerance callout can be one of the biggest cost decisions on a turned-part print.
On a CNC lathe, tighter tolerances often mean slower cutting parameters, lighter finish passes, more in-process checks, and more final inspection. When that precision protects fit or function, it is worth it. When it is applied too broadly, it narrows the process window and increases both cost and scrap risk. Read More
Small design changes on turned parts can reduce cycle time, tool wear, and handling in production.
When a turned part moves from prototype to repeat production, cycle time is no longer just a machining issue. The design of the part plays a major role in how efficiently it can be produced. Read More
