Model:TWISTER Series
ㆍAll 3 linear axes are located on top, dynamic performance independent of table loading.
ㆍX & Y axes are directly coupled with servo motors while Y-ax is driven by dual ballscrews, which ensures the precise linear movements with high acceleration and rapid feed.
ㆍX/YIZ axes are equipped with cross-roller linear guides, and optical scales.
ㆍA & C tilting/rotary axes are equipped with Renishaw high res. rotary optical encoders.
ㆍBuilt-in spindle is an essential part of excellence.

Description

ㆍTwister series model features U-shaped base, and equipped with dual-supported A/C tilting & rotary table, high speed built-in spindle, cross-roller type linear guides, and precise optical scales.
ㆍ Precise angular compensation and RTCP (Rotated Tool Center Point) functions are available (optional), to ensure the best accuracy of tool tip path during complex and irregular curved surface machining tasks.
ㆍFixture and workpieces can be easily hoisted onto the table with a crane while the roof cover is opened.
ㆍThe working area is covered with stainless steel sheets to keep it clean and elegant.
ㆍMachine top is fully covered by finned crankcase type way cover.
ㆍFully closed working environment is achieved while the way cover closes.
ㆍLarge touch screen and keyboard provides the best operating experience to the operators.
ㆍFanuc iHMI Function is available (Optional) for more innovative possibilities.
ㆍTwister features a proprietary tool magazine to minimize the machine footprint while maximizing the working area.
ㆍStandard: Carousel type 30T (Option: T-shaped chain type 40T / 60T).
ㆍATC and tool magazine are installed behind the machining area to keep the chip and dust away.
ㆍServo-driven tool magazine facilitates fastest tool selection and shortest tool waiting time.
ㆍServo-driven ATC system achieves optimized tool change time 2 secs. (Tool to Tool).
