Dynamic Precision Tool & Manufacturing was commissioned by a customer in the military/defense industry to manufacture the custom drill and ream fixture highlighted here. This high precision part was manufactured with ANSI type D2 tool steel, creating the specified profile with CNC turning and machining processes, executing the precision finishes and details employing multiple grinding techniques including surface grinding, jig grinding, and ID/OD grinding. A range of advanced equipment were utilized for this construction including Mazak CNC Lathe, Hurco CNC machining center, Okamoto surface grinder, Heald OD/ID grinder, and Moore CNC G48 jig grinder.

Finished dimensions for the fixture were an outside diameter measurement of 28", and a height of 2.31". The tightest tolerances required, including ±0.0005" true position, ±0.0003" on jig ground bores, ±0.0002" squareness, and within ±0.0005" on OD and ID’s. The part exhibited a combination raw machined and 32 Ra surface finish. Quality and accuracy were ensured with comprehensive dimensional and visual inspections. 1 unit was created after a turnaround time of 6 weeks, delivered to the customer in Sunnyvale, California.
