Burr Oak Tool in Sturgis, MI with 300+ employees and 420,000 ft2 in 3 production facilities, supplies special machines and tooling to virtually every user of air conditioner evaporator condenser coils in over 70 countries around the world.
Over the years the company sought to continuously refine their processes to reduce cost and increase productivity. In the mid 1980s they began using through tool high pressure coolant delivery on their high speed steel drills.
They purchased first LNS ChipBLASTER in 1994 to use higher pressures. They found that these units performed significantly better, lasted longer and required less maintenance. The LNS ChipBLASTERs allowed the company to run 1,000 PSI coolant on all machines with coolant filtration levels of one micron. This combination has cut down machining time to turn hours into minutes and minutes into seconds when machining steel and aluminum parts. They currently have 60 LNS ChipBLASTER high pressure systems in use.”
They built special flow gauges that mounted on the spindle or mill tool holder to measure precisely how many gallons per minute they needed to deliver to maintain the optimum cutting parameters.
They determined that their CAT 40 machines required 13 GPM and the CAT 50 machines needed 21 GPM to achieve more consistent pressure and cooling, so LNS ChipBLASTER changed the pumps accordingly. By delivering the precise amount of flow and pressure, Burr Oak Tool saw improved tool life and faster throughput.
One example of the benefits of through-tool high pressure coolant at Burr Oak Tool is a stripper plate for a die that requires 3,200 holes drilled into 34 RC 4140 steel The holes are 1mm in diameter and 6 mm deep. Originally, this process involved a solid drill – and typically produced a number of broken drills – and lots of pecking. Using the LNS ChipBLASTER to deliver high pressure coolant through a single drill enables machining all 3,200 holes with no pecking. This coolant method combined with using a speed head cut production time from 6 – 8 hours down to 40 minutes.
Because applications like this one require drilling very small holes, The LNS ChipBLASTER units are equipped with 1 micron filters that eliminate tiny particles that could clog the small tools.
“When people ask me about how through-tool high pressure coolant delivery helps our production, I tell them it’s as simple as this: With the right equipment, like the LNS ChipBLASTER systems, we can cut steel like it’s aluminum and aluminum like it’s wood.” Explains CEO Newell Franks II.
