Chamfering Tool Reduces Cutting Resistance, Burr Generation
Big Kaiser is introducing the R-Cutter CKB Type, a modular round chamfering tool.
Big Kaiser is introducing the R-Cutter CKB Type, a modular round chamfering tool. The tool is an ultra-high feed front and back radius chamfering mill, featuring high rake angles that reduce cutting resistance and minimize burr generation. It offers an insert geometry which improves sharpness. The tool is offered in a four-insert design to cut in tight spaces and attain higher feed rates.
The connection is equipped with a floating drive pin that engages on both sides into respective pockets in the mating part. The tapers on the pins and the angles on the pockets are engineered to automatically balance the two resulting torsional forces. Additionally, the connection allows for an array of standard shanks and extensions to be adapted with the heads to create “custom” tools to extend over 16", maintaining damping near the cutting edge and managing vibration in long-overhang setups.
The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
