The Challenge

Cycle time is crucial, so what’s taking you so long? 

Time is money when it comes to moving finished parts through your manufacturing process. Our customer was machining 316 stainless steel to produce pump covers for the food processing industry. Each part had 2 holes that included an interrupted cut, and our customer needed 2 different tools to complete the process. The roughing tool they used ran for 8.5 minutes per hole, and the finishing tool ran for 23.5 minutes per hole. Overall, our customer was spending over 1 hour to complete a single part. 

The cycle time was killing productivity, and our customer knew there had to be a more efficient solution available. They tested the Wohlhaupter Combi-Line boring system, and the results were exactly what our customer needed. The Combi-Line tool slashed the cycle time from 1 hour to just 17 minutes, less than 1/3 the previous cycle time (a 73% reduction). Equipped with a height adjustable roughing unit on one side and a precision finishing tool on the other, the Combi-Line achieved both the rough and finish processes with 1 solution. This multi-function combination eliminated the need for multiple tools and reduced our customer’s inventory requirements. 

Another challenge our customer faced with their previous tooling was insert damage. They struggled to produce even 1 part without chipping an insert in the stainless steel material. With Wohlhaupter’s stainless steel grade inserts designed specifically for success in this type of material, the Combi-Line tool solved the chip damage issue for our customer. 

Thanks to the Combi-Line tooling solution, our customer’s lengthy, troublesome process became a worry-free application that could be completed 73% faster. Don’t struggle with inefficient applications; call your local tooling specialist, and find the right tool for your job today.
