Heule Precision Tools has introduced versatile COMBI tooling that can be configured to drill, chamfer, countersink, and in certain configurations, spotface in a single, compact tool. This technology is designed to save time and money while optimizing space utilization.
"Eliminating tool changes significantly reduces cycle times and enhances efficiency while ensuring consistent, high-quality results with each operation," said a company spokesperson. "These tailor-made solutions provide unmatched versatility and adaptability to site-specific manufacturing challenges."
Sizes ranging from 9.5 mm to 35 mm (0.374" to 1.378") are readily available for immediate delivery, thus minimizing downtime and production interruptions. Through coolant is available, as are varied lengths to improve rigidity or meet specific application requirements. COMBI tooling is suited for precision, high-volume applications, like those of the heavy equipment/large parts industry. Common automotive industry applications include wheel, axle, and brake disc applications, and more.
The COMBI tool uses a standard spade drill and SNAP chamfer blade to create drilled holes that are chamfered and deburred on the front and back of the workpiece in one operation.
The drill forward-feeds completely through the workpiece until the spade drill insert clears the part. Then rapid feed so the SNAP blade is positioned just above the workpiece surface. Feed the tool forward to produce the front chamfer. When the SNAP blade is retracted in the hole, only the ground sliding surface touches the hole, protecting it from damage while the tool is fed through the part in rapid feed. There is no stopping or reversing the spindle.
When the blade reaches the back part past the burr, the chamfer blade extends to the cutting position and then the tool is retracted within the same working feed and speed. When the blade is again in the hole, the tool can be rapid fed out and on to the next hole. Standard countersink COMBI tools add pocketed ISO inserts to the tool body create large front countersinks.
