3 VMP-16 Multifunctional machining center with emphasis on performance Achieves high accuracy machining Highly rigid construction Powerfully resists bending and twisting with double-column structure to maintain stable accuracies. Slideway of each axis uses a sliding system with special plastic applied. Roller bearings are also used on surfaces that support heavy loads to enable high-accuracy positioning. Stable machining accuracies are maintained with the use of large-diameter ball screws and pre-tensed rigid supports. Positioning accuracy,, Z axes 0.0 mm/0 mm ( in./11.81 in.)

4 VMP-16 Solid machine with compact design of a small machine Large working range Large working range is obtained with 1,200 rotary table and spindle rotation. Applications for a vertical machining center can be used in cutting with the vertical spindle position, and those for a horizontal machining center can be used with the horizontal spindle position. With specifications in the vertical spindle position there is no interference with the column thanks to the double-column structure, enabling deep pocket milling. Spindle vertical position working range (3.94) 20 (13.78) (9.84) 800 (31.0) Max rotation: Travel: (61.02) (Spindle thru: 1420 (.91)) 1400 (.12) Travel Spindle horizontal position working range (3.94) (1.7) (9.84) Travel 700 (27.6) (Spindle thru: 8 (32.68)) 820 (32.28) Superior cutting performance Table Maximum load capacity of 3,000 kg (6,600 Ib) on 1,200 table to handle cutting of workpieces up to ø2,000 (78.74 in.). In addition to continuous cutting and multi-sided machining with NC indexing, position clamping can be done with curvic coupling every, enabling heavy-duty cutting. (clamp torque 29,400 N-m (21,618 ft-ibf)) Precision tapered gear used in table rotation. Together with the nobacklash structure, a rotary encoder is also standard equipment. This improves indexing accuracy.

Forced automatic lubricating oil supply systems are used for the ball screws and support bearings of each axis. Coolant circulation to the support bearings also gives stable accuracies even with continuous cutting over long periods and reduces need for maintenance. Long-life design uses measures to prevent cutting fluid contamination with air dryer unit as standard equipment and mist lubrication and air sealing of spindle bearing (40.7) (88.8) [Max work size] Setup station ø1600 (62.99) Spindle center Main operation panel Improved ease of use 2-pallet APC (optional) Two-pallet APC that enables easy work outside the machine is optional equipment for loading and unloading of large, heavy workpieces and fixture setup. Crane operation can be freely done with this 2- pallet APC even with full enclosure specifications. The table can be freely rotated with the 2-pallet APC, making loading and unloading of workpieces easy. 6

Drilling on slopes or relieving holes can be done easily with the pulse handle (electronic handwheel at right). Handle feed perpendicular to tool axis Handle feed can be done perpendicular to tool axis with spindle at an angle. Sloped planes can be easily machined with this Okuma pulse handle. Decrease cutting resistance Tool head coordinates Tool-axis tool length comp 3-D coordinate conversion Without spindle incline Chip thickness Large Small With spindle incline Tool length offset B B Z Feed per revolution: Same Z Highly efficient curved surface milling C 2 setup changes were necessary in the past to cut parts that have multiple flat surfaces as shown in the diagram. With -axis control, multi-sided machining is possible with a single setup. As a result, installation errors from setup changes are eliminated and machining accuracies are improved. Reduced tooling cost Special tools C Straight end mill Face milling Increase tool life Ball-nose end mill Large Small Pick difference By inputting tool length (spindle swivel center to tool head/tip), tool head coordinates and actual speed (tool axis direction pulse handle feed) can be displayed. Machining samples Tool length compensation on the tool axis can be done even when the tool axis rotates, and is not always the Z axis. Without this function the program must be remade to match the tool length when tool lengths differ. This allows programmers to simply use an - plane to make drilling or specific shape programs and apply the required coordinate center, direction, and angle per selected axis to a slope. Cutting speed is zero 3-axis machine -axis machine Tapered end mills or other special tools not needed; standard tools can be used Since the direction of the spindle with respect to the machined surface can be freely controlled, side cutting with a straight end mill or curved surface cutting with a face mill can be done. Cutting times are greatly reduced compared to point contact cutting with a ball end mill. Additional advantages are improved cutting efficiency and extended tool life by cutting with the tool at an angle to the machined surface. 7 8

9 Fire Safety Precautions To protect your factory and equipment from fire and assure continued safe operation, observe the following fire safety precautions whenever you operate machinery. Whenever possible, avoid the use of oil-based coolants for cutting operations. Sparks caused by hot chips, tool friction, and grinding can cause fires. Always observe the following safety measures to ensure safe operation when machining flammable materials or when performing dry machining. 1. Oil-based coolant (1) Use nonflammable cutting fluid coolant. (2) When the use of an oil-based coolant is unavoidable: Before you begin machining, check cutting tools to make sure of their service life and the condition of the tool edge, and choose cutting conditions that will not cause a fire. Periodically clean the coolant filter to maintain sufficient coolant discharge, and frequently verify that coolant is discharging normally. Take measures to control the outbreak of fire: Place a fire extinguisher near the machine, have an operator constantly monitor operation, and install an automatic fire extinguishing system. Do not place flammable materials near the machine. Do not allow chips to over accumulate. Periodically clean the inside of the machine and the area surrounding it. Check that the machine is operating normally. Never run the machine unattended. Since an automatic fire extinguishing system and other peripherals are needed for grinding operations, please let us know as soon as possible if you plan to perform such operations. 2. Precautions regarding machining of potentially flammable materials Before machining any material designated by law as a flammable substance, e.g., plastic, rubber, wood, acquaint yourself with the special characteristics of the material in terms of fire prevention, and observe the precautions given in (2) above to ensure safe operation. Example: When machining magnesium, there is a danger that magnesium chips and watersoluble coolants will react to produce hydrogen gas, resulting in an explosive fire if any chip should ignite. 3. Dry machining Dry machining is a fire hazard because workpieces, tools, and chips are not cooled. To ensure safe operation, do not place any flammable objects near the machine and do not allow chips to over accumulate. In addition, be sure to check cutting tools to make sure of their service life and the condition of the tool edge, and observe the precautions regarding oil-based coolants given in (2) above. When using Okuma products, always read the safety precautions mentioned in the instruction manual and attached to the product.
