It is also capable of cutting high-speed steel.

Rush Machinery specializes in manufacturing, servicing, and marketing a complete line of production and support machinery for the cutting tool industry: wheel truing and dressing machines, dynamic balancing machines, carbide rod and HSS cut-off machines, grinding fluid filtration systems, polycrystalline tool grinders, drill and tool grinders, as well as tool grinding fixtures. 

Arno Werkzeuge USA VNMG Insert introduces its SA series of cutting tools and inserts for grooving and parting-off or cutoff operations. The modular grooving system, using a single toolholder, can be transformed into different tool variants by changing the support blade and clamp. Enabling different operations with one tool, this grooving system provides chip removal in all three main cutting directions. The SA range also features precision-ground two- or three-edged cutting inserts in various designs, shapes and types to maximize Carbide Threading Inserts cutting performance, speed and efficiency.

The series comes in three unique systems—monoblock, modular and blade-style—to accommodate the requirements of machining operations in aerospace, plastics and medical industries. The company says the SA series provides a cost-effective solution for radial grooving as well as parting off of diameters ranging to 5.512" (140 mm). The SA monoblock holder is used with a range of double-sided inserts including the Arno SA16, SA17, SA24, SA35 und SA40 in widths of 0.059", 0.079", 0.118", 0.157", 0.197", 0.236", 0.315 " and 0.394" (1.5, 2, 4, 5, 6, 8 and 10 mm).  

Sandvik Coromant has developed a method for turning that uses the Y-axis for complicated shapes and pockets with a single tool. The method is said to offer reduced cycle time, improved component surface quality and more stable machining.

The new turning method makes use of the Y-axis, and all three axes are used simultaneously when machining. The tool rotates around its own center, with the insert placed for machining in the Y-Z plane, and the milling spindle axis interpolates during turning. Sandvik Coromant says this enables APMT Insert intricate shapes to be machined with a single tool.

Two new tools have been developed to support Y-axis turning. The new CoroTurn Prime variant is suitable for shafts, flanges and components with undercuts. The CoroPlex YT twin-tool, which features CoroTurn TR profiling inserts and CoroTurn 107 round inserts with rail interface and can be used for components with pockets and cavities.

Y-axis turning offers the ability to machine several features with a single tool, and no tool changes are required, which minimizes the risk of “blend points” or irregularities between adjacent machined surfaces. The main cutting forces are directed into the machine spindle, improving stability and reducing the risk of vibration. A constant entering angle is said to drastically improve chip control and help avoid chip jamming.

Turning has developed in recent years with new innovations, such as all-directional PrimeTurning, non-linear turning and interpolation turning. “One could say that these advances, together with progressive capabilities in modern CCGT Insert machines and CAM software, have paved the way for the new Y-axis turning method,” says Staffan Lundström, turning product manager at Sandvik Coromant. “And with the tools and method now in place, we look forward to exploring the possibilities this method can present to our customers.”

Sharp Industries’ M series of large-swing, big-bore manual lathes is suitable for large oil pipe work, heavy shaft turning jobs and large-diameter steel rods. The series includes lathes with swings of 40", 50", 60", 70" and 80"; distance between centers ranging from 60" to 315"; and spindle bores sizes of 6", 9" and 12"

The Sharp M-series machine base is a one-piece structure made from high-grade Meehanite casting to maintain durability and stability under heavy cutting conditions. The 32"-wide bedways are induction-hardened and ground with separate bedways at the front of the bed to support the heavy carriage RCGT Insert and apron. According to the company the bedways promote better dispersion of cutting force from the carriage. The apron is equipped with a six-way control of the carriage and cross-slide movements. The cross-slideways are coated with Turcite-B for improved oil retention and wear resistance.

The headstock is designed with three-point bearing support of the spindle, and the large spindle motor enables power ranging to 50 hp. The spindle is made from forged chrome alloy material, while the gears and shafts are made from hardened and ground alloy steel. The rear chuck adapter enables Machining Inserts double-chuck mounting, and the heavy-duty tailstock is available with motorized movement on the quill and the base for ease of operation, the company says.

CAM software that supports 3 + 2 machining has helped make this technique a valuable option for users of five-axis machining centers. The 2014 R2 release of PowerMill CAM software from Delcam includes new utilities that enable the programmer to more quickly find the most advantageous workplane Surface Milling Inserts orientation, cutting tool tilt angle and tool length. This speeds the process of optimizing the 3 + 2 program, and makes checking for collisions faster and more thorough. One of these utilities, Dynamic Machine Control, enables the programmer to simulate the motion of the tool tip dynamically and instantly evaluate the effects of program edits to avoid collisions in the tool path.

Operating in 3 + 2 mode involves using the two rotational axes to lock the cutting tool in a tilted position before executing a three-axis milling program. This combination of three-axis milling and two-axis tool positioning gives this technique its 3 + 2 nickname. The main advantage of 3 + 2 machining is that it allows for the use of a shorter, more rigid cutting tool than would be permissible with conventional three-axis machining.

With 3 + 2, the spindle head can be lowered closer to the workpiece with the tool angledtoward the surface. Using a shorter tool, in turn, enables faster feeds and speeds with less tool deflection. This means that a good surface finish and more accurate dimensional results can be achieved in a shorter cycle time. Other benefits include shorter tool movements, fewer lines of program code and fewer machine setups.

Nevertheless, a 3 + 2 tool path requires the same careful preparation, verification and optimization as a full five-axis part program.

For example, one of the new utilities is a software toolbar that can be opened when a toolpath simulation stops after it detects a potential collision. Called Dynamic Machine Control, this toolbar enables the user to quickly and easily adjust any axis position in an existing tool path in order to avoid the collision. The programmer can test and evaluate these adjustments instantly by dynamically moving the repositioned tool tip around that tool path while it remains in constant contact with each toolpath segment. If this movement of the tool tip detects further collision points, the programmer can click on graphical “grab handles” that enable the tool to be tilted and rotated manually into a new position that avoids the problem area. For each repositioning, the software can create a workplane that is aligned to the adjusted cutting tool axis and machine tool orientation.

To aid this process, the toolbar includes a machine tool position dialog box, also new,that can be opened to view data on the position of the machine tool, together with the limits set for each axis. This dialog box also shows the range of motion set for each axis of the tool in its current orientation. This is depicted by a slide bar representing the travel limits for that axis. Sliding the indicator on the bar automatically controls the position of the tool as displayed in the simulation, and it is a handy way to jog the machine components into position during the editing process. A warning pops up if an axis limit is exceeded.

At any point, the programmer can return to dynamic control of the tool tip. When finished making whatever adjustments in Tungsten Steel Inserts the tilt and rotation of the cutting tool are necessary to avoid all potential collisions, the programmer simply updates the tool path and runs the simulation as an additional check. A video demonstration of Dynamic Machine Control can be found at short.mmsonline.com/clear3+2.

Other enhancements in PowerMill 2014 R2 include an enhanced boundary editing history form, a composite curve creator that merges adjacent arcs and surface edges, an improved hole creation and editing utility, and more.
