Toyoda Machinery has announced its new quill spindle horizontal machining center, the FH1250SW. This quill spindle version of the FH1250SX combines the original HMC's speed with the capabilities of a boring mill, developed to increase efficiency and versatility of large part machining through process integration. The machine demonstrates maximum power during large diameter drilling and boring cuts. The 60-horsepower, 3,000-rpm spindle boasts 968 ft./lbs. of torque, making it ideal for steel and casting applications. Equipped with a 5.11 inch quill diameter, the FH1250SW is capable of a 21.6 inch W-axis stroke. The spindle is engineered with proprietary bearing technology capable of accommodating a cutting thrust load up to 4,500 ft./lbs. The machine's standard NC table supports workpieces up to 11,000 lbs./5,000 kg table load capacity, and the Y shaped pallet changer configuration allows for simultaneous setup of two pallets. The FH1250SW is equipped with dual axis ball screws in both Z and Y axis. The oil-chilled ball screws are included on the x, y and z axes to suppress thermal displacement during long cycle times. The 49x49 inch pallets with X, Y and Z travels allow for large applications to be handled with ease, the company reports.
Related Glossary Terms
- boring
boring
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
- machining center
machining center
CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
- numerical control ( NC)
numerical control ( NC)
Any controlled equipment that allows an operator to program its movement by entering a series of coded numbers and symbols. See CNC, computer numerical control; DNC, direct numerical control.
