JASPER recently acquired a Haas VF-6 CNC for its Diesel Division. This machine has the ability to resurface an engine block as well as bore the cylinders. “What makes the CNC machine better is that it can resurface a block twice as fast, compared to standard machining practices, without compromising surface finish,” says Ryan Dooley, JASPER Diesel Division Manager. “The machine can bore out the cylinders five times faster than standard machining.”

“It would take about 40 minutes to manually set up a block to be bored and resurfaced,” he added. “With the CNC machine, that process is cut in half.”

Dooley says the Haas VF-6 currently machines the bigger medium-duty engines remanufactured within the division. “It machines all of our Cummins engines, all of our Caterpillar and Duramax engines, and we have future plans to have it machine the counterbore inline International engines,” he said. “This CNC machine currently accounts for about 35% of our production.”

With the new CNC machining process, Dooley says the customer will see added value and benefits from a JASPER product. “We’re able to machine the same block, without compromising quality, in half the amount of time,” added Dooley. “So it’s helped us become more efficient in providing a product to the customer in a shorter amount of time.”
