1 Rigid and Precise CNC Lathes Rigid & Precise

2 Rigid & Precise Ever since our first machine tool rolled off the production line in 1968, we here at Mori Seiki have continued to make CNC lathes that are praised by customers everywhere. Over those 35 years, we have released around 100 models. We can say with confidence that we believe every single one was an improvement on its predecessor. Today, we are on the threshold of a new beginning in the field of CNC lathes, and we are determined once again to create a lathe that will lead the industry in innovation. After reworking our designs, and incorporating data received from confronting heat related problems and thousands of customer comments, we have improved our products even more. Our uncompromising development stance has made it possible to deliver unprecedented rigidity, precision, and reliability. Our efforts have created our newest line, the NL Series. These new machines are high-rigidity, highprecision CNC lathes and set the new standard in common sense machining for a new age.

5 Rigid & Precise Innovative turret design Turret with a built-in milling motor The milling mechanism on conventional lathes generates a great deal of heat and vibration due to the large number of parts involved, including the motor and gear belt. The NL Series, however, features the industry's first turret with a built-in milling motor. This revolutionary design minimizes heat generation and vibration while eliminating transmission losses. The new design increases both machining accuracy and cutting performance. Face mill 80 mm (3.1 in.) Tapping capacity M20 The NL Series was designed to create a CNC lathe with true milling capability. For example, the NL2500 can accommodate face mills of up to 80 mm (3.1 in). NL Series machines boast milling performance approaching that of No. 40 taper machining centers. 5 Actual size

6 6 20 Extremely rigid turret In order to enhance the milling function, it is essential to increase the rigidity of the rotary-tool holders. The NL Series rotary-tool holders have a broader grip as compared to conventional lathes. By raising attachment precision we have vastly improved rigidity. Super-rigid rotary-tool holders Taking a hint from couplings, which are praised for their high repeatability, we developed a very rigid rotary-tool holder. Comparison of rotary-tool holder rigidity Conventional lathes leave chatter marks when the depth of cut is made deeper, but with the NL Series, it is now possible to cut to a depth equal to the tool diameter. This is attributed to the tool holders that have been designed to be more rigid. Previous model Tool diameter and depth of cut Tool diameter and depth of cut 20 mm (0.8 in.) 1015 mm ( in.) Coupling diameter Previous model 210 mm (8.3 in.) 250 mm (9.8 in.) Rotary-tool holder rigidity 180 % Greater Greater coupling diameter than before. Coupling diameter 19 % Greater 20 mm (0.8 in.) 20 mm (0.8 in.) Tool diameterdepth of cut mm (0.8 in.)

7 High-performance rotary tool spindle A DDS motor that has no gear belt is used for the rotary tool spindle, delivering high-speed, high-efficiency machining. Rigid & Precise Max. rotary tool spindle speed Previous model 4,000 min % Greater 6,000 min -1 Rotary tool spindle acceleration time Previous model 04,000 min sec.

This has achieved rigidity between the spindle and the tool tip that exceeds that of conventional two-axis lathes. 7 A solid construction that can hold its own with the NL Series two-axis models. Y-axis travel (Y-type) I50 mm (I2.0 in.) I60 mm (I2.4 in.)

8 The ultimate in turning Improved tool tip rigidity Our goal was to minimize tool tip vibration, thus reducing the need to grind after cutting as well as extending tool life. The NL Series achieves this with its increased rigidity between the spindle and tool tip. 8

9 Handles large-diameter workpieces Rigid & Precise Although the NL Series machines remain rock solid during heavy-duty cutting, their design incorporates the largest spindle through hole in its class <91 mm (3.6 in.) for NL2500>. Through spindle hole diameter (headstock 1 spindle) 61 mm (2.4 in.) 73 mm (2.9 in.) 91 mm (3.6 in.) 105 mm (4.1 in.) Through spindle hole diameter 91 mm (3.6 in.) Thanks to high rigidity, machining no longer requires additional grinding. Increasing the rigidity between the spindle and the tool tip has made it possible to achieve high quality machined surfaces through turning alone. End face finishing accuracy Conventional machines create a pattern on material due to the amount of vibration the tool tip generates. With the NL Series, there is no pattern on the material, thus eliminating the need for grinding.

10 Ultra-high rigidity structure We have a new design for the basic structure: the spindle, saddle and tailstock. This new design ensures consistent rigidity. The result is a level of rigidity that has not been seen before, with increased stability due to the broad bottom face. Torsionally rigid 100% Greater <comparison to conventional machines> Bed torsion rigidity Dramatically better bed torsion rigidity compared to conventional machines has been achieved through static analysis.

We have achieved an unknown level of stability not only in turning work but also in milling work. Guideway width 30 %Greater <comparison to conventional machines> 10 Previous model A Previous model B

11 Highly rigid spindle Rigid & Precise The axis rigidity of the headstock and its mounting have been improved by changing the shape of the headstock and increasing the thickness of its parts. The diameter of the bearings has been increased. This allows better spindle rigidity while enlarging the through-hole diameter. Axis rigidity 20 % Greater Headstock attachment rigidity 30 % Greater 50 %Greater <comparison to conventional machines> Improved acceleration/deceleration time and torque specs Raising the rigidity has endowed the NL Series with performance equal to that of spindle motors one class above. Acceleration/deceleration time Previous model Spindle acceleration time (04,000 min -1 ) 4.9 sec.

12 Thermal isolation Designed to eliminate all heat The most prominent feature of the NL Series is said to be the elimination of the adverse effects of heat. In order to raise the continuous machining precision of lathes, 95 % of which is said to be taken up by cutting time, we at Mori Seiki have come up with the concept of total heat elimination. Heat elimination layout Previous model It is common to find the oil cooler a major source of heat located right next to the spindle in conventional machines. As a result, the headstock is affected adversely by that heat. Large heat displacement Oil cooler Placing the oil cooler behind the machine removes that heat source from the headstock. The machine is designed so that the exhaust from the oil cooler doesn t come in direct contact with the machine. Spindle thermal displacement Displacement (mm m m Time (hour) Oil cooler/rear side, exhaust blocked X-axis tip) Previous model Oil cooler/left side surface layout X-axis tip) Fully-covered bed Oil cooler/rear side, exhaust blocked X-axis base) Oil cooler/left side surface layout X-axis base) Covering the bed with a cover makes it difficult for the heat from chips to be transmitted to the bed. Oil cooler Low heat displacement Oil cooler exhaust vent The oil cooler s exhaust heat is blown out of the cover in the direction of the machine s side. 12

13 Spindle Cooling Rigid & Precise We have redesigned the spindle, which is the greatest source of heat, to employ a uniform-heat construction that maintains an equal temperature all around the spindle. The main spindle unit is protected from rises in temperature by the spiraling oil jacket located all the way to the back side. Inverter-controlled oil cooler An inverter-controlled oil cooler with very accurate temperature regulation has been used. Oil jacket Milling turret with a heat-suppressing design Internal design of the turret Oil jacket Built-in milling motor The industry s first turret with a built-in milling motor minimizes heat. Previous model Motor Built-in milling motor Timing belt 1 Keyed shaft The built-in milling motor design has Timing belt 2 eliminated the transmission mechanism. Involuted spline Therefore, sources of heat are eliminated and jacket cooling is performed. This is Bevel gear only achieved with a built-in milling motor. Keyed shaft The transmission with all its gear, belts, and more, generates a substantial amount of heat and can adversely affect machining precision. 1/10 Rising turret temperatures or less Ball screw shaft cooling Shaft cooling is used on ball screws to control heat during feed. X-axis only. 13

14 Rigid & Precise Machining power By employing a super-rigid construction for the NL Series and equipping it with a turret with a built-in milling motor, it is able to deliver cutting equal to that of machines one class above.

18 Convenience Rigid & Precise Easier and faster. The NL Series was designed to deliver the convenience and setup performance of a machine one class above. Setup time Reduced by over Tailstock spindle operating time 50 % Reduced 20 by over % More applications The digital tailstock, which has outstanding functionality as a tailstock, uses a servomotor drive that allows it to be used as a third spindle. Digital tailstock The NL Series comes standard with a new feature a highly rigid digital tailstock driven by a servomotor. This drastically reduces set-up time. (New standard feature does not apply to S-, SMC- and SY-types.) Fewer steps requiring operation of the tailstock The operator is freed from the hassle of having to lock the tailstock when changing to a workpiece of a different length, connecting it to the turret, etc. Operating time reduced With the conventional hydraulic system, changing the tailstock spindle settings was inconvenient, so there was a limit to how much operating time could be reduced. A digital tailstock with variable feed speed control allows separate speeds to be set for approach and engagement, reducing the operating time of the tailstock spindle by over 20 %. Variable pressure control using program instructions With a hydraulic tailstock spindle, thrust is controlled indirectly using a hydraulic pressure meter, so if you use different machine models, you will get different thrusts even if the same pressure is set. With a digital tailstock, however, the thrust is measured directly, so the workpiece engagement is done accurately, raising machining precision. Simple operation using MAPPS Approach position, retract position, re-chucking, and more can be done simply and easily from the MAPPS screen. Besides being able to handle a variety of different workpiece types, it can also work with M-code thrust selection as a standard feature.

20 Maintenance Rigid & Precise Minimizing machine down time. In our constant effort to become the most trusted machine tool company in the industry, we design Mori Seiki machines with maintenance and reliability in mind. Machine cover design We designed the machine covers so that maintenance locations are easily seen when they are removed, and the openings have been made wider to allow easier access. See-through design (machine rear) We have used a see-through material for the rear cover, making maintenance even easier. Replacing windows Machine downtime is further reduced by using a door design that enables window replacement without having to remove the door. 20

21 Spindle unit replacement A spindle design with a separate rear bearing housing makes it possible to replace the spindle unit without having to remove the motor wiring. The time it takes to replace the spindle is dramatically shorter when compared with previous models. Turret centering adjustment Removing the machine side covers provides access to the decentering pin and all the coupling bolts, including the cap bolts. This has made turret centering adjustment much easier. Cap bolt Decentering pin Pull out the coolant tank in front With the new design, the coolant tank can be pulled out in front without having to pull out the chip conveyor. It can be pulled out easily and does not take up extra space in the back. Maintenance devices Easily perform regular maintenance thanks to the device layout, which was designed from the point of view of the operator. Lubricating oil (for sliding surfaces) tank The supply hole for the lubricant tank for the slideways is located in the front of the machine for easy refilling. Central location of air equipment The air equipment is located on the right side panel in order to facilitate maintenance. 21

22 Automatic operation support (option) Rigid & Precise What customers expect from automated devices has expanded from the automation and unmanned operation needs of the past to include greater reliability, reduced non-cutting time, and quieter operation. Mori Seiki has poured more resources into design in order to develop automated devices that raise productivity. Gantry-type loader system We have achieved completely automated start-to-finish machining using only one machine, from material supply to discharging the completed workpiece. This is a high-speed mass production system that reduces non-cutting time. Loader hand A close confirmation switch comes as a standard feature, thus improving the reliability of the work chucking.

29 MC Turret with milling function Y Turret with Y-axis control S Headstock 2 spindle While milling with the spindle rotating, multi-axis turning is made possible by simultaneously controlling three axes, including the C-axis. This flexibly meets processing needs even when involving drilling processes or complex shapes. Controls tool center height in both the direction of the workpiece diameter (X-axis) and the direction of the axis (Z-axis). Achieves high-accuracy machining even with processes such as offset key grooving or drilling off-center holes, which are difficult for conventional turning centers. A sub-spindle is mounted in the machine. When the first process completes, you can immediately transfer the workpiece to the sub-spindle, achieving continuous machining with both high speed and high precision. 2-axis turning MC Y S SMC SY Center variations Standard chuck size <headstock 1 spindle/ headstock 2 spindle> Bar work capacity 1 Number of tool stations Travel <X-/Z-axis> Travel <Y-axis> [ ] Option inch 6 -inch 80 mm (3.1 in.) 12 [10] tools 260/795 2, 1,345 3 mm (10.2/31.3 2, in.) 100 <50> mm (3.9 <2.0> in.) 2-axis turning MC Y Center variations Standard chuck size Bar work capacity 1 Number of tool stations Travel <X-/Z-axis> Travel <Y-axis> [ ] Option inch 90 mm (3.5 in.) 10 [12] tools 280/820 2, 1,370 3 mm (11.0/32.3 2, in.) 120 <60> mm (4.7 <2.4> in.) 1 Depending on the chuck/cylinder used and its restrictions, it may not be possible to reach full bar work capacity. 2 Distance between centers 700 type 3 Distance between centers 1250 type The photo shows the machine equipped with options. 29
