Aluminum Threaded Knobs

Knurled Knobs

Elge Precision Machining, Inc. was contracted by an electronic parts manufacturer in need of a reliable manufacturer for aluminum knurled knobs. Used within a custom application, these knobs needed to be produced accurately and economically in large volumes. We decided that a screw machining approach would be best for satisfying these goals.

Our single spindle Brown & Sharpe screw machines were retained for production of the knobs. Individual fabrication processes included rough turning, drilling, form turning, counter boring, trepanning, thread rolling, and knurling. 6061-T6 Aluminum was specified as the build material. Tolerances were held at ±0.001”, with 32 RMS finishing placed on most surfaces. All completed parts were subject to dimensional and fit tests before being individually packaged and shipped out on lead times of 4-5 weeks.

The customer was very pleased with the results of our manufacturing approach. Parts were machined well within the tolerances requested, on time, and without any interruption to the customer’s existing work flow.
