Machining

Tungaloy Corp. offers TungForce-Rec, the indexable miniature shoulder milling cutter. The TungForce-Rec insert has a unique V-shaped bottom to enhance the insert's resistance to centrifugal force, assuring reliability and high productivity during high-speed machining, according to the company.

Tungaloy Corp. offers MillQuadFeed, a new high-feed milling cutter. With a depth of cut up to 0.098" (2.5mm) and a feed rate up to 0.078" (2.0mm) per tooth, MillQuadFeed accomplishes astounding metal-removal rates in rough milling operation, according to the company.

DoTriple-Mill is Tungaloy's latest facemilling cutter, featuring an innovative dovetail clamping system that will reportedly dramatically reduce insert lift up and excessive shear force imposed on the screws during heavy-duty milling. Compared with the last generation of facemilling platforms, DoTriple-Mill delivers stable machining and consistent tool life.

Allied Machine & Engineering announces the expansion of its AccuPort 432/AccuThread 856 program to include more than 120 kits for manufacturing hydraulic ports and manifolds. The kits are available to meet SAE J1926, ISO I6149, John Deere G1731 and SAE AS5202 (aerospace standard/Mil-Spec) specifications.

Allied Machine & Engineering announces Wohlhaupter's VarioBore precision boring head and system, a versatile and cost-effective tool that features a universal digital readout module. The VarioBore system improves productivity through ease and accuracy of adjustment and virtually eliminates scrap because of its exact adjustments.

The cutting edges of cutting tools don't actually produce chips. Instead, the pressure of a rapidly spinning tool on a workpiece plasticizes part of the parent material, creating a shearing effect that forces the material to ride up the tool.

DoForce-Tri from Tungaloy America accepts a double-sided insert with six cutting edges. Three types of inserts are available to meet the needs of many different jobs: a standard wiper insert with an MJ chipbreaker on true 90-degree cutting edges or with an NMJ chipbreaker on serrated cutting edges, as well as a radius insert with an MJ chipbreaker on large round corners for edge toughness instead of wipers.

Saint-Gobain Abrasives has introduced CarbonForce, a new lightweight line of vitrified CBN wheels for OD grinding. With proprietary high-strength carbon fiber cores, CarbonForce wheels are 75 percent lighter than heavier steel-hubbed wheels and provide the safety and performance-enhancing benefits of a precision superabrasive wheel, according to the company.

Advanced CNC systems from NUM are helping U.S. machine tool control specialist CNC Onestop Inc. to maintain its competitive market edge through use of ultraprecise positioning techniques. Based in Xenia, Ohio, and also operating in Toronto, Canada, CNC Onestop is a CNC engineering company that specializes in full CNC, motor and drive retrofits for machine tools, as well as machine rebuilds and troubleshooting.

The deluxe line of variable-speed grinders from Palmgren delivers the power, precision and versatility to complete a wide range of finishing applications. At high speeds, they reportedly are the ideal choice for heavy material removal, deburring and chamfering.

J.W. Winco Inc. offers GN 421.12 metric size, technopolymer plastic, hollow knurled knobs with a stainless steel threaded stud and swivel thrust pad. Temperature resistant to 194° F (80° C), the RoHS-compliant hollow knurled knobs have a ball end whose diameter is smaller than the core diameter of the thread.

To bring needed safety to the shop floor, Rockford Systems LLC has launched a new milling machine draw bar cover (part #DBC001) to protect vertical mill workers from rotating shafts 7 feet or less from the floor or working platform.
