Hyundai WIA announces its all new i-CUT320M high-speed compact CNC vertical machining center, tailored to the unique needs of the electronics, mold, and medical industries.
The i-CUT320M features a 24,000rpm direct drive spindle, which is capable of ridged tapping at 6,000rpm. The i-CUT320M delivers Hyundai WIA’s smallest footprint within its range of Mill/Drill VMC’s, which also includes the; i-CUT380M, i-CUT380T, i-CUT380TD, i-CUT420M, i-CUT420T, and i-CUT420TD.
Main Spindle
The i-CUT320M is configured with a 24,000rpm direct drive spindle for taking deep cuts at high-speeds for precision applications. Ultra precision angular bearings provide high-speed accel/decel for smooth machining at high rpm’s. The standard oil cooling system maintains the temperature of the main spindle, reducing thermal growth, and increasing part accuracies. Rapid and accurate tapping is assured, resulting in rigid tapping at 6,000rpm.
The standard Big Plus spindle system provides dual contact between the spindle face and the flange face of the tool holder. This greatly increase tool rigidity, reduces run out, and adds significant productivity to any machining application. Spindle motor is 14hp with spindle torque rated at 8/6 Nm. The Big Plus spindle offers users the fastest possible material removal rates, the highest accuracy, and excellent rigidity. It guarantees stability when run at high spindle speeds for high rpm precision machining.
Bed Structure
The bed, column, and saddle of Hyundai WIA’s compact high-speed i-CUT320M are designed using finite element analysis to ensure powerful cutting and agility, and are composed of meehanite cast iron to minimize deformation when performing heavy-duty cuts. The rigid bed is designed to absorb vibration for stable machining. In order to eliminate thermal growth during machining, high-precision double-nut balls screws drive all axes. The double pretension design provides outstanding positioning and repeatability with virtually no thermal growth. All ball screws are connected directly to the servo drive motors without gears or belts, eliminating backlash. Linear motion guide ways in all three axes achieve rapid, high-speed axis movement. This reduces non-cutting time and decreases machining time for greater productivity.
ATC and Magazine
Hyundai WIA’s i-CUT320M VMC is outfitted with 20-tool (24-tool optional), side mount swing arm type tool changer. This technology offers optimal performance with impressive tool change times of 1.5 seconds, tool-to-tool.The side mounted swing-arm ATC and magazine are separated by a shutter system which closes during machining, thus keeping chips and fluids clear of the ATC and magazine. When a tool change is required, machining stops, the shutter opens, the ATC exchanges old tool for new, the shutter door then closes and machining begins again.
Control
The all new i-CUT320M is easy to program and operate with a Siemens 828D Series CNC control featuring a 10.4” color LCD. The 828D offers compatibility and reliability for mold and medical industries.
