We used 0.050 ±0.003” thick 1095 spring steel, 0.375” thick black ABS plastic, and 4-40 UNC x 5/16” screws with washers for the assembly. The assembly was finished with a black oxide using spin-drying to add mild corrosion resistance and minimize light reflection.
We employed a punch press, a wet grinder, a CNC vertical milling machine, a sanding machine, a hand-file, and a pneumatic screwdriver to get the job done.
Blanking and piercing were used to stamp the “L” fingers and pierce two holes in each. Grinding and filing were necessary on the outside edges of the left and right fingers. Once the three pieces were machined, they were assembled using four screws with washers.
The finished products measured 0.925” in width x 6.030” in length x 0.800” in height and weighed just 1.0 oz. A tolerance of ±0.0025 was achieved in the finger blank with the help of precise CNC controls.
We performed a thorough dimensional inspection to ensure that the customer-supplied CAD specifications were met. In the end, we produced 1,000 assemblies and delivered the finished products to our client in the Midwest in only six weeks.
