Save machine time and set-up costs by burnishing a variety of part surfaces with one tool.
Save machine time and set-up costs by burnishing multi-surface parts on NC/CNC machines with one tool. · Produce high-quality, 5. To 8. micro-inch finishes (0.13-0.20¼m). · Burnish at feeds and speeds comparable to cutting tools. · Improve part wear through cold working. Now you can burnish IDs, ODs, fillets or contours, shoulders & bar ends with one tool The Multi-Surface Single Roller Burnishing Tool is designed to be positioned in the boring station of an NC/CNC machine. The path of the burnishing tool is then programmed to identical to that of the cutting tool used prior to burnishing. The Multi-Surface Tool has a unique design which permits the burnishing roller to be spring loaded in two directions. This allows the roller to exert a uniform pressure on the part regardless of the parts shape. The result is a uniform low micro finish. Most outside diameters, bar ends & inside diameters greater than 2.5 inches can be burnished automatically after boring or turning. In addition, fillets, contours, radii or shoulders can be automatically burnished by machine programming. A 5 to 8 microinch finish is practical at a feed rate double that of the cutting tool. Speeds consistent with good machining practices are recommended. Coolant is not required, but is recommended when used for other machining operations. Perform multiple burnishing operations just as you would cutting operations The illustrations show a part being burnished automatically in stages. In illustrations #1, the inside diameter is being burnished. In #2, a fillet between the inside wall and the part bottom is being burnished. In #3, the part end is being burnished. In #4, a shoulder is being burnished. Of course, the OD beyond the shoulder would be the next surface to be burnished.
