Mazak Corp. offers the Integrex i-100 Bartac-S multitask machine, which incorporates enhanced CNC technology and high-speed servo systems to offer high levels of productivity when processing small high-precision parts in
single setups, as well as machining bar material up to 4" in diameter.
The Integrex i-100 Bartac-S has two turning spindles and a milling spindle for full 5-axis machining and Done In One operations. The main spindle employs a 15-hp integral motor spindle with maximum spindle speeds of 2,000 rpm and a large 4.4" spindle bore. It offers high-precision C-axis contouring by indexing in 0.0001-degree increments. The 15-hp, 6,000-rpm second spindle indexes in increments of 0.001 degrees for C-axis contouring and features a 2.4" bore size.
The machine’s powerful 10-hp, 12,000-rpm milling spindle is mounted in the rotating B-axis, which has a 240-degree range of motion and indexes in 0.0001-degree increments. B-axis scale feedback comes standard on the machine to ensure high motion accuracy, while the milling spindle may be upgraded to 20,000 rpm for high-speed machining.
The machine comes standard equipped with a 36-tool magazine that accommodates tools up to 5.1" in diameter when neighboring stations are empty and up to 3.5" in diameter when stations are occupied. For further tooling versatility, the machine also has a 72-tool magazine option as well as an automatic toolchanger (ATC) that can
exchange both fixed and rotary turning tools.
The Integrex i-100 Bartac-S provides expansive axes travels of 8.2" in Y, 17.7" with a below-centerline capability of 1.96" in X and 35.5 in Z, allowing the machine to process a wide range of part sizes and shapes. All three linear axes achieve high-speed 1,575-ipm rapid traverse rates.
In terms of CNC technology, the machine features the new Mazatrol SmoothX CNC, which makes it easy to generate programs for the production of highly complex parts. As a key element of the Smooth Technology process-performance platform, the CNC has several advanced functions that allow it to ensure the shortest possible
machining cycle times, especially in fine increment programs for simultaneous 5-axis operations and free-form die/mold machining.
Ergonomics also play an important role in the functionality of the Mazatrol SmoothX CNC. A large 19" display presents all of the critical machine data at once, while the tilt control panel allows for optimal positioning based on operator height. An intuitive multitouch screen, which is similar to that of a smartphone, enables fast and smooth
programming operations. An SD card allows the CNC to store up to 32GB of data. Through its Intelligent Bar Loader System, the Integrex i-100 Bartac-S brings advanced tactics to bar work machining. The system automatically feeds out the material the required distance from the machine’s chuck and minimizes the bar remnant. An optional chuck pressure management system automatically changes by part program for a wide variety of workpieces. It maintains not only the set chuck pressure per workpiece, but also the same pressure when changing material.
The finished workpiece is removed by the optional compact integrated work unloader in the upper part of the second spindle as opposed to an auto-parts catcher. A powered conveyor then transfers the workpiece outside of the machine. The unloader hand is designed to prevent any marring of the finished workpiece. The optional Intelligent Bar Loader System and work unloader are essential to unmanned operations.
Designed for convenient system installation, the Integrex i-100 Bartac-S has a 127" x 103.8" footprint, which requires minimal floor space when compared with conventional equipment that utilizes a gantry loader or robot system.
Related Glossary Terms
- automatic toolchanger
automatic toolchanger
Mechanism typically included in a machining center that, on the appropriate command, removes one cutting tool from the spindle nose and replaces it with another. The changer restores the used tool to the magazine and selects and withdraws the next desired tool from the storage magazine. The changer is controlled by a set of prerecorded/predetermined instructions associated with the part(s) to be produced.
- chuck
chuck
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- milling
milling
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.
- rapid traverse
rapid traverse
Movement on a CNC mill or lathe that is from point to point at full speed but, usually, without linear interpolation.
- toolchanger
toolchanger
Carriage or drum attached to a machining center that holds tools until needed; when a tool is needed, the toolchanger inserts the tool into the machine spindle. See automatic toolchanger.
- turning
turning
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
