Indiana shop thinks big, creates jobs

Julian: When we bought the company, it consisted of a 4,000-sq.-ft. building with a few pieces of machinery and no employees. We now have 48,000 sq. ft. with all work areas under an overhead crane. Our number of employees stayed consistent through the recent recession until December 2011, at which time we added seven employees, increasing employment by 25 percent. The demise of a few tool shops around the area has allowed us to pick up new work and hire some of their people. One of our secrets to success is having larger equipment and more equipment than is typical for a machine shop of our size.

CTE: What kinds of large equipment?

Julian: Our lineup includes two boring mills with 20 ‘ of travel, five honing machines from 2.5 ” to 18 ” ID and up to 24 ‘ in length, and a very large trepanning and gundrilling machine. We continue to add additional equipment and recently bought a heavy-duty TOS lathe, which will help us work on large shafts. It handles work from 33 ” in diameter and 140 ” between centers. We have found we can process more shafts if we “take the bark off” prior to CNC lathe profiling. However, to do this we needed a larger lathe, one stout enough for continuous duty, and the TOS lathe fit the bill.

CTE: So adding more machines led to hiring more employees?

Julian: Yes. We recently diversified into another business segment: building our own machining cells for short-run production. This allowed us to run the machines with fewer employees. Increased business allowed us to add more employees, but not as many as we would have if we didn’t have the machining cells. Wouldn’t it be great if it took only half your workforce to run your daily production? Well, in essence, that is what we oftentimes do with the layout of our CNC milling machines. This is a newly implemented secret of operating efficiently. When one operator runs one machine, all of the labor cost is directed to the single part being machined. When the operator runs two machines, at least one of the machines is running without an operator. This allows you to split the operator’s cost over two machines or by the number of parts per process.

Chesterfield Tool specializes in designing and building custom machines and tooling, trepanning, honing, gundrilling and remanufacturing hydraulic cylinders.

There are two attributes that come out of this practice: You can lower your operating costs, and you can run twice the amount of labor through each operator. The machining cells aid us in getting our costs down. We are now a low-cost solution for machined parts. On some machine building RFQs, we have been asked to buy parts from China, for example, to help keep our selling price competitive. We can compete on this global level of cost, yet make the parts in the U.S.A. Further, because we are running twice the number of parts through the machines, our delivery times are shrinking. Low cost plus quick turnaround equals happy clients.

Chesterfield Tool grinds shafts from 5 ” to 8 ” in length with a 0.0002 ” tolerance on this OD grinder.

CTE: What makes Chesterfield Tool a solutions-oriented company that tackles jobs other shops won’t?

Julian: We are skilled toolmakers and problem solvers. Many times we are asked to make new or reproduce one-of-a-kind parts. Having skilled toolmakers and manually operated equipment is still the best and most cost-effective way to make such parts. We do not produce a product and attempt to sell it. We are approached by customers who have a specific need for a product that no one has ever designed or built a machine before for their process. It’s nice to know that in these times of everything leaving the country, we are still able to produce something of value the rest of the world doesn’t have. If we’re going to be competitive in the U.S. and world markets, we have to continue to work smarter and be the vanguards of innovation and ingenuity. CTE
