4140 Alloy Steel Drive Shaft for Industrial Gearbox OEM
Material: 4140 pre-hardened · Tolerance: ±0.0005″ on bearing journal · Qty: 60 units
Challenge: Industrial gearbox OEM needed replacement drive shafts with a bearing journal running clearance held tighter than the original casting-based supply chain could reliably produce. Prior supplier delivered shafts with 40% requiring hand-fitting at gearbox assembly.
Approach: Turned each shaft on the Chien Wei CWB-450-CNC in a single fixturing to preserve concentricity between the bearing journal and drive-end features. Probed the journal after roughing to compensate for tool wear across the lot. CMM-inspected the journal diameter on 100% of parts and documented capability against the customer print.
Outcome: Hand-fitting at assembly went to zero. Cpk on the bearing journal was 1.94 across the 60-unit lot. Customer moved 4 additional gearbox part numbers to Olympus over the next 6 months.
Aluminum EOAT Body for Automotive Robotics Integrator
Material: 6061-T6 · Tolerance: ±0.001″ on tool interface · Qty: 12 unique EOAT configurations
Challenge: Robotics integrator building a body-in-white welding cell needed 12 unique end-of-arm tooling bodies delivered within a 3-week window to meet the customer's installation date. Each EOAT had different sensor pockets and pneumatic passages but shared a common robot-side mounting interface that had to be dimensionally identical across all 12.
Approach: Programmed the common robot-side interface as a locked subroutine, then customized the tool-side geometry per configuration. Ran all 12 configurations back-to-back in a compressed schedule with dedicated fixture stations to minimize setup time. Every EOAT body received a CMM check on the robot-side interface pattern before release.
Outcome: All 12 EOAT bodies delivered on day 19 of the 21-day window. Zero interface fit-up issues at cell integration. Robotics integrator added Olympus to their approved-shop list for follow-on cells.
Delrin Fixture Plate for High-Speed Packaging Line
Material: Delrin (acetal) · Tolerance: ±0.002″ on locating features · Qty: 200 units (initial + repeat)
Challenge: Packaging equipment OEM needed a wear-resistant fixture plate for a high-speed food-packaging line with a strict cost target driven by end-customer margin pressure. Prior aluminum design was over-budget and prone to product damage from metal-on-product contact.
Approach: Value-engineered the design in Delrin instead of aluminum with the customer's engineering team, reducing material cost by 60%. Adjusted feeds and speeds for acetal to hold locating-feature tolerance without heat distortion. Ran a first-article plus 25-unit pilot before scaling to the full 200-unit release.
Outcome: Total delivered cost came in 32% under the previous aluminum baseline. Zero product-damage incidents in the first 6 months of production. Customer standardized on Delrin for two additional fixture plate part numbers.
