Growing Business real-time monitoring. Tis software may be used with existing NC systems and is compatible with G-code programming. Finally, controlling the interface between the toolholder and the spindle is important. Choosing a dual contact (taper and face), such as Big Plus or HSK, provides a better interface than a standard CAT or BT toolholder. At any speed, a machine tool spindle is subject to centrifugal forces, which increases as speed increases. At high speed, centrifugal force is strong enough to make a spindle bore grow slightly. As a collet segment rotates, the clamping mechanism gains centrifugal force also and causes the relatively thin walls of the tapered shank to defect radially at a faster rate than the wall of the spindle. Tis contributes to a stronger contact between the shank and the spindle, without afecting the axial position of the cutting edge, as it is determined by the face-to-face contact between the fange and the receiver. An HSK toolholder has contact on the spindle face and taper. When the spindle begins to grow, the face contact prevents the tool from moving up the bore. Most commonly, shrink-ft toolholders are used in precision machining because they aford total contact between The FVM-104160DC is perfect for lean, repeatable mass production of large and heavy workpieces. The slanted Y- and Z- axes increase the slideway surface and eventually distribute the load in the area. The series also features these benefits: • The FVM double-column VMC has an extremely rigid and stable structure base on oversized columns, extrawide spacing of box ways on a slanted Y-axis and a close symmetrical design of the Z-axis. • The four heavy-duty linear roller ways of the X-axis support the table and boost moving speed, dramatically reducing stick-slip problems caused from box ways machines and increasing the machines positioning accuracy. tool and holder, approximating a solid carbide tool. Tis avoids the efects of temperature and vibration on the tool, supporting machining precision and high quality die surfaces. Te design of the machining center, machine build techniques at the factory, easy-to-use software suites embedded in the machine tool control, and the experience of operators and programmers are the keys to choosing the best machining center for any precision turning shop. Selecting a VMC: Tings to Consider Vertical machining centers are ubiquitous. A standard three-axis machine may do the job, but as you can see here, the addition of a rotary table provides signifcantly increased capability.

The coolant circulation in the 3" large balls crews eliminates thermal building and ball screw deformation, helping to maintain high-positioning accuracy and repeatability. • The 50-taper, cartridge-type, air-purge, 6000rpm with 30 HP spindle is driven by a two-speed gearbox with low speed for extra-high torque output during heavy cutting. It generates a maximum torque of 449 ft.-lbs. Think versatile. Call your Chevalier dealer today to learn more about the FVM-104160DC.
