4 General Construction CONSTRUCTION Machine Component Design and Construction The basic structural elements of the Turning Center are produced from high tensile strength alloyed cast iron that is carefully stress-relieved. All elements are computer designed for exceptional stiffness. The base and bed, cross slide, headstock, tailstock and turret form a balanced, rigid structure. Okuma casting know-how and the toughest quality assurance results in the best machine foundation possible. Bed The 45 degree bed is Integral box-type construction of the Z-axis and Tailstock guideways. All bed way surfaces are induction-hardened on a specially designed Okuma hardening machine to 56 Rockwell C scale. The distance across large rectangular ways provides optimum support for the carriage and cross slide. Okuma Box Way technology This is a must to sustain the rigors of turning. Integral Ball Screw bracket construction Hand scrapped for final assembly Surfaces machined as one with guideways Base The heavily ribbed base casting provides mounting support for the Bed and all the machine sub-systems. The combined assembly counteracts cutting loads and deflection. This is the key to the machine s stability and repeatable accuracy. Base is machined mounted on designed foundation pad location Five face machining completes all critical relationships in one machine Hand scraped headstock mounting surfaces in final assembly Casting configured for separate coolant tank. The isolation of coolant and chips provides thermal stability of the headstock and base. Page 4 of 24

5 Headstock and Spindle Rigidity, accuracy and part finish CONSTRUCTION The Okuma LU7000EX M cast iron headstock houses the spindle and is designed to easily handle the maximum drive capacity. In order to provide the best power and torque configurations the LU7000EX is offered in a total of 9 different spindle configurations. The LU7000EX M has a base mounted VAC electric spindle drive system that employs either an auto shift four gear design to produce large torque values in all ranges for the B08 spindle and two speed VAC motor for the B12 spindle. The headstock is hand scraped to the bed mounting base. The Headstock has a discrete lubrication system with filtration, cooling and interlocks for monitoring correct operation and low reservoir condition. The spindle is supported by three sets of double row cylindrical roller bearings and high-speed dual angular contact ball bearings. A three-point bearing support provides the rigidity and long life for this very accurate spindle.

9 MECHATRONICS Axis Drives Ball Screws Powerful, robust ball screws generate slideway movement to both axes of the Okuma LU7000EX M. In contrast to general commercial drive systems, the Okuma servomotors precisely match the electrical and mechanical characteristics of the Okuma LU7000EX M. A key element in the drive system is the unique Okuma absolute position, digital feedback encoder connected directly to the shaft of each Okuma axis servo drive motor. Cross section of typical axis assembly Both X and Z-axes are driven by the ultra-precise ball screws and pre-loaded ball screw nuts, center-mounted between the ways for optimum drive conditions.

10 Four Axis Technologies About 4-axis timing MECHATRONICS The idea of 4-axis is one thing, execution is another. The chief Okuma advantage in four-axis is the power of the OSP CNC control to offer ease of use and complete flexibility of turret timing. Put the cutting tools where and when they are needed. Two tools simultaneously or sequentially, from upper or lower turret. Okuma continues to be the preeminent supplier of this highly productive processing technology. Programming Conventional two-axis programming language. OSP makes the conversions for the lower turret. Machining is synchronized by P-codes (P1--Pn ) as assigned by the programmer. Machine Set-up Conventional two-axis set-up methods for touch-off and prove out. A toggle switches between upper and lower turret information. The standard graphics allow full simulation of the program ahead of slide motion. Individual switches allow turrets to prove out one at a time. Distance left to travel appears for both turrets on the same screen. Operation Running: The large control screen allows tending at a glance. Preview program adjustments before moving a slide. Adjustments: Tool offsets are supported by animation showing results. Adjustments can be monitored for excessive amounts. Interruptions: Okuma mid-auto manual function allows interruption when desired. Back the tools out, turn the spindle off. Resume without restarting Restarts: The Okuma provides four methods of restarting the program where you want to, even in fixed cycles. ID and OD work simultaneously (22 tools ready) 4-axis benefits Reduction of machining time: High Accuracy machining: Simultaneous cutting by both turrets significantly reduces cycle time. A single turret may be dedicated to a finish cut. Reduction of noncut time: processing the next tool can In cases of two axis be at the ready eliminating time lost to index and turret positioning. Expanded flexibility: Reduction of setup time: Turret mounted live center Turret mounted part unloading Turret mounted steady rest/ follower rest Chip stripping of the other turret More permanent tooling remains set-up. Less set-up time Advanced One Let the optional Interactive Touch (Optional) - Advanced One Touch The fastest 4-axis programming software programming: breeze through the part programming. Then drag and drop processes for optimization. Page 10 of 24

11 Four Axis Technologies Okuma OSP CNC - 4-axis timing example MECHATRONICS Tool and Cutting Conditions The net cutting time per piece is 68 (s) when the part is cut in 4-axis simultaneous cut mode. It will be 131 (s) if the part is cut in conventional manner. This means that simultaneous 4-axis cut yields nearly 48%.

13 ACCURACY AND REPEATABILITY Machine Position and Geometry The rigid machine structure coupled with a high response positioning system provides the following machine positioning accuracies and repeatability: Accuracy: X-axis: (0.012 mm) over any 4 (100 mm) of stroke. Z-axis: (0.020 mm) over any 12 (300 mm) of stroke. Repeatability: X-axis: +/ (+/ mm). Z-axis: +/ (+/ mm). These accuracy guarantees are based on the procedures below. Machine Position and Geometry Inspection Laser alignments, mechanical alignments and positioning accuracy checks are among the 200 quality tests performed on every machine. Lead screw compensations are measured during final inspection and maintained in the Okuma control to insure the stated accuracies. X and Z Axes Positioning Measurement: Procedure for determining positioning accuracy on X- and Z-axes is by laser measurement of a single, unidirectional, rapid traverse move of the cross-slide to a programmed position 3.93 (100 mm) along the X-axis. Afterward, the Z-axis is moved (300 mm) from the starting position. The measured travel of cross-slide is compared with the commanded target position. The difference between the two numbers is the positioning accuracy for X and Z-axes. X- and Z-Axis Repeatability Measurement: The X- and Z-axes positioning test procedure (above) is repeated seven times. The difference between the largest result and the smallest result is the repeatability of X- and Z-axes. All moves are unidirectional, rapid traverse, single axis moves. Turret Indexing Accuracy The machine turret is a critical element in maintaining part piece integrity. The precision turret assembly is designed and manufactured by Okuma and achieves an indexing accuracy of +1.5 sec. ( [0.002 mm]/station). Thermo-Friendly Concept Okuma s Thermo-Friendly is a structurally designed, thermal deformation control system that provides astonishing machining accuracy. It frees the machinist from troublesome offsets and machine warm-ups, is superb for long runs, multi-tasking, front/back end work, plus applications. Hand scraping improves Geometry and Rigidity Page 13 of 24

14 FLUID SYSTEMS Machine Lubrication Slideways and ball screws are lubricated by a centralized lubrication system. The system consists of a heavy-duty lubrication pump that feeds a series of precision piston distributors delivering the exact amount of oil required at each lubrication point. Machine Hydraulics Self-contained Hydraulic unit is enclosed by sheet metal of the machine minimizing pump db. The main unit and important sub-systems are interlocked with the CNC to provide safe operation. Controls for chuck, and tailstock are provided at the front of the machine for ease of operation. Chip & Coolant Control Proper chip removal is essential in maximum metal removal conditions. The 45-degree bed construction permits chips to fall directly onto the chip pan without accumulating on the slides. The chip pan is perforated to permit coolant to pass into the coolant tank. The separate coolant tank minimizes heat transfer involved with coolant and chips. The roll away feature offers quick and thorough tank maintenance. A tank level sight glass is provided for visual control of coolant supply. The separate roll away coolant tank system comes complete with perforated metal screens and filter unit. An independent 1.46 hp (1.1 kw) pump unit is standard. CNC command and manual control provide 4 gallons per minute and 100 psi. through the turret to the tooling nozzles. 1000C 2000C 3000C TBD 254 gallons TBD Optional Chip Conveyor For machining operations where large quantities of chips are produced, an optional lift and drop chip conveyor is available for the right side exit.
