5 High rigidity High accuracy! Perpendicular type spindle head stock concept Unit Construction (Front) New concept Y-axis (compound slide ways) compact space Unit Construction (Rear) Simultaneous Machining Can Be Performed with Ease In addition to unrestricted machining possibilities that are performed easily, independent two-path control provides the capabilities of two machines in one. Simple, accurate work piece transfer is performed through direct chucking: the right spindle slides coaxially to the fixed left spindle assuring precise exchange of parts while both spindles run simultaneously. Due to the low center of gravity, the bed restrains vibration which affects the machining accuracy, and improves the rigidity of the machine. Massive Spindle Headstock for Continuous Heavy Duty Cutting A wide range output spindle motor provides increased torque at lower spindle speeds. For machine slides, fast-response AC servo motors provide quick acceleration and fast rapid traverse feed rates. The absolute positioning pulse coder eliminates the necessity for constant zero return procedures. AC servo motor Detects excess loading. Less heating caused by appropriaiate electric current control depending on loading. Possible to get higher speed and stable high torque by stepping motor. (Appropriate for transferring long stroke. ) 5

6 High rigidity Super high rigid slide 2 way slide structure is adopted on the bed. The upper slide is horisontal, and the lower is 45 degree slant. Because of well balanced structure, cross sectional surface area become larger, and stability, also become much better. Therefore super high rigid structure base is achieved. High productivity High Speed Z-Axis Rapid Traverse 27 m/min (1575 ipm) Shorter idle time is achieved with faster rapid traverse rates of 16 m/min (630 ipm) for the X-axis and 27 m/min (1063 ipm) for the Z-axis. The Y-axis that has a stroke of +/-60 mm (+/-2.36"), allows machining of accurate keyways, drilling off-center holes, face milling, chamfering and circular threading(op.). Two Independent 12-station Turrets Providing up to 48 Tool Positions Up to 24 tools per turret are available, which permits processing of the most complex parts. The 24-station bi-directional turret features high speed indexing. (0.2 sec to adjacent tool) It adopts servo motor positioning and the shorter path selection function to ensure precise indexing in the shortest time. 6

7 Support Software for Operationality ESPRIT (option) Turning With 2-D data for 2-spindle machine, the vertural tool is loaded. Then, it does rough machining, finish machining, grooving, threading, and pocketing. Complex machining Simultaneous machining of turning and milling is possible to XZC/ XYC axes. Also, complex drilling to edge face/od, Outlining and pocketting are possible. Rough machining (OD/ID/edge face) Pocketing Copying lathe Outline Grooving Threading Cutting off Drilling (fixed cycle) bar feeding C/Y-axis milling OD/edge face drilling Outline Pocketing Mult-tasking complex machining Multi-turret, Multi-spindle Simultaneous turning/milling definition to Multi-turret, Multispindle is possible. The backside operation after the part transference to the sub-spindle, simultaneous machining with the upper and lower turrets and waiting are utilizable in the simulation function. The solid simulation is available just after defining, so it is possible to check the machine operation and make the best machining path. 2-turret, 2 spindle 4-turret, 2-spindle 7

8 Operator Friendly Software Support for Operationality Plenty of supporting software for operator Easy Programming [Luck-Bei II as standard feature] Machining cycle creation (conversational) function Reduce programming time NC solid animation function Reduce program checking time Edit function Reduce program editing time Code list display function M-code list display Net-Monitor [option] This is a software to integrate and manage multiple machine information from a personal computer. Among this software's features is monitoring the running condition of every machine at a glance,sending alarm notices to a mobile phone via the internet and advance notice of machining completion in coordination with NT nurse system 2. Displaying detailed information Program input / output Displaying actual operation Displaying CNC screen Displaying information of NT nurse system 2 Handy Phone Internet Operation Data Program server 8

9 Work environment support User friendly These functions here are to minimize unavailability of the machine. They are upgraded maintenance facility to avoid damaging the machine. Excess load detection Minimum damage parts if collision occurs! This feature minimizes the damage to machine in case of crash caused by mistake in operation or programming. It works by detecting excessive load immediately (within 8/1000 sec.) and tracking back. This function is effective at all times for all slides (X, Z, Y, C and B-axis), differently from load monitoring function which is effective only for selected tools. Less skills without Excess load detection with Excess load detection Cutting insert and its sole plate will be broken, and the turning tool holder is moved off by the shock of crash. Cutting insert and its sole plate stay the same, and the turning tool holder is a little bit slipped even if the tool is hit by crash. 9

10 Work environment support User friendly NT Work Navigator [torque type] Tremendous cost savings by elimination of positioning jigs and fixtures! Less fixtures This is a standard software pursuing new methods to detect material's position and shape with the help of torque control feature. VA (Value Added) proposal is dramatically achieved. *Detection bar is not included. NT Nurse System 2 A machine management feature that contributes to important reductions in set-up time! 1.Load monitoring function (Spindle & Servo motor) -Tool breakage detection -Tool life function 2.Tool management function -Tool groups / sister tooling -Set through cutting tool call up frequency, cutting time or cutting distance 3.Operation conditions function -Workpiece counter -Machining time -Automatic operation time -Power ON Time 4.Software work pusher function -Monitoring servo torque during workpiece transfer. Second operation chuck is closed when the workpiece end face hits a stopper or the back of the jaws. 5.Peck feed drilling -Monitoring the feed motor load. Peck drilling step depth is adjusted automatically depending on machining load. Less set-up Load monitor Tool counter *These are support software features to display necessary information when operator finds difficulty in set-up operation. 10

11 Optional features Parts catcher Parts catcher A Finished part or bar remnant is unloaded with the swing bucket from the left spindle to a closed box or an open chute. Finished part is unloaded with gripper hand from the right spindle. Finished part is unloaded with the bucket on the lower turret to a closed box or an open chute. Parts catcher A Parts catcher G Turret parts catcher Tool setter This is to facilitate tool setting more quickly and precisely. By touching the tool to one of four sensors depending on its direction, tool offset amount is set into memory automatically. Work piece zero position can be set by touching one tool onto the face of a part. High pressure coolant pump system This option is to meet the ever increasing demand for heavy duty cutting, efficient washaway of cutting chips and cooling effect on machining surface and innovative development of cutting tools. HAN-BEI In-process Measuring system Setting values necessary for carrying out the measuring cycle can be independently set for both O.D. and I.D. measuring operations. This allows for the optimum values in the required measuring cycle to be set. No tool interference in compact tool holder design. The new HAN-BEI-Mill is introduced for complex machining series. It has measurement software for 3-dimensions: cross, straight, and angular milling. Measured data is automatically input in the NC. 11
