2 Simultaneous 5-axis control revolutionizes the shop f loor More than 70 years since the production of the first lathe. AMADA MACHINE TOOLS has won the trust of the customers by supplying excellent machine tools in the field of small precision part processing. This is testimony to their sincere and hard work in devising solutions to the problems the customers have to overcome. We continue to thoroughly examine what we can do as a leading machine tool builder in relation to the problems arising in the production field, where the demand to improve is getting increasingly more severe, and have developed a brand new turning center, the Mi-8, by reviewing the machine from the customers' standpoint. This simultaneous 5-axis control processing machine dedicated to the production of small complex parts is a creative integration of new technology, innovative design, and traditional expertise. Please take a look at the Mi-8, which integrates the lathe engineering technology of AMADA MACHINE TOOLS acquired through long years of tough work in this field.

4 Basic Machine Structure The ultimate machine, taking up the challenge of extreme accuracy without compromise Axis Configuration NC unit FANUC 31i-A5 Axis Stroke Minimum unit of setting X-axis 250mm 0.001mm Z-axis 305mm 0.001mm Y-axis 345mm 0.001mm C-axis 360deg 0.001deg A-axis 270deg 0.001deg A-axis: 270 deg. C-axis: 360 deg. The introduction of the A-axis enables processing of slanted holes with the standard specification, without using the conventionally required angle unit. The "complete in one chucking" feature eliminates dimensional errors caused by rechucking. Ｙ-axis:345mm Z-axis: 305 mm X-axis: 250 mm Turning spindle High-accuracy Built-in Spindle for Turning Operation A built-in spindle, making the most of the experience through manufacturing lathes, has been adopted accuracy processing. Four rows of bearings support the front part of the rigidity. In addition, a dedicated cooling unit is installed to displacement. we have acquired to achieve highspindle to assure minimize thermal Tool Main Spindle As with the turning spindle, the tool spindle, which features minimized thermal displacement and high rigidity, operates at a maximum speed of min-1 to process holes as small asφ0.5 mm at a surface speed of 32 m/min. To hold rotary tools, an HSK shank suitable for high-speed operation is used. The two-face (end face and tapered face) constraint structure reduces positioning error in repeated operation to ensure high accuracy processing. φ32mm Close contact with end face Close contact with tapered face HSK shank 3

6 NC Unit Software s load due to concentration for a long time, skills and verification steps, which were all necessary for conventional programming, can be reduced. Complex shape can be programmed in a simple operation! An operator who only has experience of operations on lathes can operate the software. The use of the CAM software reduces the time, skill and verification needed in conventional programming.

7 Mi-8 [16-station stocker + Articulated robot specification] The 16-station stocker and the articulated robot, installed in an area 630 mm wide, serves as an automatic loading / unloading system. Multiple types of workpiece material can be handled since a CCD camera automatically recognizes the shape of the workpiece material. Robot FANUC Robot LR Mate 200iC Number of controlled axes 6 axes Reach 704 mm Wrist load capacity Max. 5 kg* Repeatability ±0.02 mm Weight of robot body Approx. 27 kg * Includes the weight of hand, transport fixture and workpiece. Tool breakage detector The tool breakage detector provides the following two functions. Detection of tool breakage Detects breakage of a tool by receiving the light emitted from the photoelectric sensor. Automatic tool offset Detects the length of a tool using the skip signal. 6
