The hole story on gear quality
Forest City Gear President Fred Young has a straightforward philosophy for acquiring and retaining business. The company's strategic directive is: "Excellence without Exception." It boils down to always giving the customer a higher level of quality than specified on a print - or in any other interaction with a customer. "The goal is to do this without adding much cost or time to a job," Young explains. "We do everything we can to distinguish our product from competitors', and we try to do it inexpensively. On bore-type gears, we have found that automated honing is a good way to give the customer tighter control of bore size, roundness, straightness and finish. The customer notices the difference in a smoother, quieter, more efficient drive, and unless we stumble in some other aspect of the job, we will have a repeat customer. The trick in gear manufacturing is to add this value without adding cost for the customer."
