This short ≈ 1 minute video outlines our CNC Machining capabilities:

KAF Manufacturing’s CNC Department is unique. We can bar feed and chuck diameters as small as 1mm. The largest diameter we can bar feed or bar pull is 3.00″ diameter. For chucking work we can chuck 15″diameter and swing 21″diameter. The Turning Department has onboard programming that is supplemented by an offline programming system known in the industry as “Esprit”, a product of DP Technology.

Most milling machines have work-holding fixtures for multiple work pieces to maximize the use of a tool once it’s in the spindle, while the smaller CNC Lathes use a magazine feed system that loads shorter bars. These machines also have programmable parts catchers coupled with the bar feeders that provide for unattended operation when the process permits.

With regard to CNC Milling, we now offer High Speed Milling with a spindle speed of 50,000 RPM. We specialize in 5 axis milling and can drill holes as small as .002” in diameter with the new, extremely precise Datron C5. We utilize both onboard and offline programing systems. Some machines also have in-process probing systems permitting the work to be inspected in the machine during the manufacturing process.

Those milling machines, not 5 Axis, all have 4th axis capability. The 4th axis can be a simple indexer, or can be a true 4th axis. We have both types here at KAF and the programmer can graphically depict and demonstrate the rotary action to expedite the manufacture of complex shapes.

High-speed milling on some of our CNC machining centers with look-ahead function permits high metal removal rates while preserving the finish and dimensional demands of the product requirement.

Flatness requirements are often outside the realm of milling, facing, or grinding. We have free abrasive flat lapping both conventional abrasive and diamond abrasive. For those lapping projects that also call for parallelism, as well as, flatness requirements, we have double side planetary lapping. Our slurries are prepared at KAF and delivered to the lapping surface via a computerized pumping station.

Size control is automated by virtue of a computer-monitored position probing system. We have the inspection equipment necessary to measure the flatness and parallelism achieved.
