Chevalier Machinery will continue production of its popular FBB-110 — 130 series machine into 2014. The heavy-duty, high precision design of the FBB series of horizontal boring and milling machine with rotary table offers a wide range of machining applications.
"The extra rigid design of the main machine body and column ensure outstanding structural stability. The one-piece machine base includes four guide ways on the Z-axis for full table support with no overhang issues," says Chevalier National Sales Manager Herbert Hou.
Here are vital specs about the FBB-110 — 130 Series:
Capacity: The machine's table size is 63" x 55.1" with a table load up to 22,000 lbs. The XYZ 78.7" x 78.7" x 59". W travel is 19.7" (FBB-110)/27.5" (FBB-130). This FBB model's net weight is 64,900 lbs., with a floor space of 304" x 280" x 193". The optional magazine type ATC accepts tool's weight of up to 55 lbs. The machine has an optional chain type 40/60/80-tool magazine available.
Structure: The series features a one-piece Meehanite cast iron base with heavy-duty large box ways on X-, Y-, and Z-axes and is coated with anti-friction material for consistent accuracy and smooth movement. The high-quality C3 grade ball screws are used on all axes for high precision positioning.
Spindle: The 35HP, 50-taper, large-diameter, cartridge-type, air-purged spindle runs with German made ZF gearbox that generates a maximum of 1220 ft.-lbs. at 600rpm to overcome most tough-material cutting conditions. Spiral-type spindle cooling system provides constant, all-around lubrication, preventing thermal deformation and substantially prolonging the life of the spindle, bearings and gears. The spindle can be extended (W-axis) for deep-hole boring with high-rigidity and superior machining accuracy, according to the company.
Table: The table features a full C-axis contouring with 0.001-degree minimum intervals. It also has a hydraulic break disk plus a locking pin every 90 degrees, designed for maximum stability. The rotary table is driven by an AC servo motor with a worm shaft and gear that provides high torque for heavy work pieces. Accessories: The spindle oil cooler that controls the various temperature changes in the spindle during the machining of consistently accurate work pieces is standard equipment, along with the lubrication system. The standard lift-up chip conveyor and two internal chips augers are also all standard equipment.
Control: The FANUC 0i-MD control has the latest technology with powerful control feature with Ethernet connection; easy-access, front memory card slot; and a huge data-server memory capacity are among the many standard features.
Related Glossary Terms
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.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- 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.
