The Sky is the Limit for Golden State Engineering
  • Industry: Precision Parts
  • Process: Swiss Turning
  • MGI Division: Rem Sales
  • Outcome: Golden State Engineering was able to realize decreased production costs, production time, shipping costs, and increased efficiency, slinging them back to the lead of their competition.

 » Challenge

One of the components that GSE manufacturing engineers had identified for process improvement was a 4 9/16” valve cut from 7075 aluminum. GSE’s cycle time for this part was just under eleven minutes on a 32 mm Swiss machine – an amount of time that made the part too costly to manufacture for GSE to be competitive. With complex OD geometries, ID drilling required on most of the length of the part, and material that is tough on chip control, Mr. Goodwin knew that they would have to look elsewhere for a solution.

 » Solution

Tsugami-Rem Sales engineers worked with Ellison and GSE engineers to customize a process utilizing the G83 peck drill cycle and the coolant fed properties of the tool. Tsugami – Rem Sales engineer Greg Cox added “Tsugami’s bushing blaster - along with an interrupted cut controlled OD chip wrap for the grooves and turned diameters - allowed us to substantially reduce cycle time.”

 » Assessment

Having recently collaborated with Ellison Manufacturing Technologies to design an engineered solution for an aerospace component, that saw a reduction in operations from seven to two, Mr. Goodwin decided to consult with them again. After a thorough review of GSE’s needs by representatives of Ellison Manufacturing Technologies and Tsugami - Rem Sales, a Tsugami BS20C was recommended as the ideal solution. Built on one of the most rugged bases in the industry, the Tsugami’s Z2 axis was rigid enough to keep the ID drilling concentric to the OD.

 » Results

Peck drilling was ideal as it allowed the tool to make multiple “pecks,” breaking the chip into smaller, more manageable pieces. In addition to chip management, peck drilling allowed for longer tool life and improved ID surface finishes. In the end analysis, GSE’s cycle time was reduced to seven minutes 50 seconds with the part dropped complete; allowing GSE to keep the part in house.
