CARLSTADT, NJ — Hyundai WIA announces an 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 offers the smallest footprint within the range, which includes the i-CUT380 and i-CUT420 Series, and features a 24,000 rpm direct drive spindle, which is capable of ridged tapping at 6,000 rpms

Main Spindle

The i-CUT320M is configured with a 24,000 rpm 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 main spindle delivers minimal noise and vibration even at the highest cutting speeds, guaranteeing extremely stable machining and minimizing thermal transmission to the main spindle. Rapid and accurate tapping is assured, resulting in rigid tapping at 6,000 rpm.

The standard Big Plus spindle system (BBT #30) 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 14 hp with spindle torque rated at 8/6 Nm.  The Big Plus spindleoffers users the fastest possible material removal rates, 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 (FEA) 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, all axes are driven by high precision double-nut ballscrews. The double pretension design provides outstanding positioning and repeatability with virtually no thermal growth. All ballscrews are connected directly to the servo drive motors without gears or belts, eliminating backlash.   Rapid high-speed axis movement is achieved by the use of linear motion guide ways in all three axes. This reduces non-cutting time and decreases machining time for greater productivity.  Axes travel: X-axis, 16.5”, Y-axis, 12.6” and Z-axis, 13.” Rapid traverse: 56 m/min (all axes).

Thru Spindle Coolant

To make the i-CUT320M a true performer, Hyundai WIA offers thru spindle coolant (optional). This feature is particularly useful for deep hole drilling where it’s necessary to keep chip flow clear of the cutting surface. Thru Spindle Coolant also helps to increase tool life and decrease cycle time.

ATC and Magazine

Hyundai WIA’s i-CUT320M VMC is outfitted with 24-tool, side mount swing arm type tool changer. This technology offers optimal performance with impressive tool change times of 1.5 sec, tool-to-tool. With a capacity of 24 tools (plus one in the spindle) setup time is reduced and run times can be made longer, especially if loaded with redundant tools.

The 24 tool swing arm automatic tool changer 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 its start-of-the-art  Siemens 828D Series CNC control featuring a 10.4” color LCD. As one of the mold industry’s most popular controls, the 828D offers compatibility and superior reliability, mold and medical industries.
