CONSTRUCTION MAXIMIZING METAL REMOVAL CAPABILITY

Machine Construction Machine Component Design and Construction

The basic structural elements of the LB3000 EX-MYW Turning Center are produced from high tensile strength alloyed cast iron that is carefully stress-relieved. The base and bed, cross slide, headstock, tailstock and turret form a balanced, rigid structure.

Base

The heavily ribbed, 30-degree base casting is computer-designed for exceptional stiffness. The structure provides mounting support for Bed and Sub-systems counteracts cutting loads and deflections. This foundation is the key to the machine’s stability and repeatable accuracy.

Bed

The bed has integral box construction for mounting of the head stock and integral box-type Z-axis guideways. The mating surfaces of the turret and cross slide are hand-scraped for ideal load distribution and lubrication. All bed and saddle way surfaces are induction-hardened on a specially designed Okuma Induction Hardening machine to 56 Rockwell “C” scale. The 14.2” (360 mm) distance across large rectangular ways provides optimum support for the cross slide carriage.

Headstock and Spindle

The LB3000 EX-MYW cast iron headstock houses the spindle and is designed to easily handle the 30 hp (22kW) drive capacity. Double row cylindrical roller bearings and high-speed double angular contact bearings support the spindle. A two-point bearing support provides the rigidity for this very accurate spindle.

CONSTRUCTION: MAXIMIZING METAL REMOVAL CAPABILITY

Sub-Spindle Technologies

Concepts:

Many chucked and bar-fed turning processes can be largely completed in the first operation lathe holding.

For these type of parts, an independent second handling, a complete set-up of a second side and employing a second machine is wasteful when a sub-spindle machine can complete the minimal remaining machining using a few tools and automatic part handling.

Programming: For Okuma, the same exact part programming that runs the main spindle is the programming that runs the sub-spindle. The programmer prepares the CNC program the same way for both spindles.

In operation, the THINC mirrors the program and runs the sub-spindle. No need for the programmer to reverse or invert any programming techniques, or learn new programming.

A single code tells THINC to operate on left spindle or right spindle.

Machine Set Up: Set-up operations are uniform for both left and right spindles. A panel switch toggles between left or right spindle.

The right headstock ordinarily remains stationary on Z (W) during machining.

Part Transfer: Machining in the left spindle is completed.

A transfer of part or, a parting off + transfer is initiated by commands to the sub-spindle.

Okuma “Torque Skip” technology allows the sub-spindle work holding to feed against the part face to a predetermined level of force.

At that time the main spindle work holding may be commanded to open and then the sub-spindle work holding to clamp.


MECHATRONICS MAXIMIZING FLEXIBILITY & SPEED

Okuma Sub-Spindle Technologies

Torque Skip Permits part load sensing during transfer; The servo “feels”

the part bottoming during transfer for optimum part location and assurance of repeatable length machining.

Synchronization: Permits transfer of part during spindle rotation; including hex, square, or irregular part geometry.

Parts ejector: A general purpose, spring type part ejector is included with the standard work holding. The ejector is removable for non part catcher applications. Note: This ejector is not compatible with alternate work holding.

Optional Parts Catcher: The finished part can automatically exit the work cavity through the use of an optional part catcher. When so equipped, the catcher will empty the finished part to a door mounted catch-accumulator bin. Reference information is included in the technical supplement.


CONSTRUCTION:

Sub Spindle

The LB3000 EX-MW cast iron headstock houses the spindle and integral Prex motor with 15 hp (11 kW) drive capacity. Double row cylindrical roller bearings and high-speed double angular contact bearings support the spindle. A two-point bearing support provides the rigidity for this very accurate spindle.

Tooling Capacity & Flexibility Turret and Tooling

The L3000 EX-MYW features a V-12 servo turret. An Okuma Brushless servo motor performs the indexing of the tool turret. An Okuma Electro-mechanical encoder monitors the turret rotational position. Turret index time is just 0.1 second, with shortest path indexing selectable by parameter toggle. Stable, accurate cutting is assured by the use of a large 248 mm (9.76-inch) crown gear coupling with 60 kN (13,488 lb) of hydraulic clamping force. The standard O.D. tool clamping method is a square 1.0” inch “wedge-lock” design. I.D. Holder is 1.5 in.

Typical Ball Screw Mounting

Okuma Dual-Supported Ballscrew

CONSTRUCTION MAXIMIZING METAL REMOVAL AND FLEXIBILITY

Axis Drives Direct Driven Ball Screws

Powerful, robust ball screws generate slideway movement to both axes of the LB-3000 EX-MYW. The centrally mounted ball screws are based on proven Okuma designs and exacting performance standards, and are coupled directly to Okuma’s axis drive servomotors via “no backlash” couplings, ensuring the highest level of accuracy. Contrary to general commercial drive systems, the Okuma servomotors precisely match the electrical and mechanical characteristics of the LB-3000 EX-MYW. 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.

The ultra-precise ball screws and pre-loaded ball drive both X- and Z-axes screw nuts, center-mounted between the ways for optimum drive conditions.

Ball Screw Bearing Blocks and Ball nut mounting brackets are hand scraped for ideal assembled alignment.

ACCURACY AND REPEATABILITY MAXIMIZING LONG-TERM QUALITY

Machine Position and Geometry The rigid machine structure coupled with a high response positioning system provides the following machine positioning accuracies and repeatabilities: Accuracy: X-axis: 0.00039” (0.010 mm) over any 4” (100 mm) of stroke. Z-axis: 0.00059” (0.015 mm) over any 12” (300 mm) of stroke. Repeatability: X-axis: +/-0.00008" (+/-0.002 mm). Z-axis: +/-0.00012” (+/-0.003 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 LB3000 EX-MYW. Lead screw compensations are measured during final inspection and maintained in the Okuma OSP THINC control to insure the stated accuracies.

X and Z Axes Positioning Measurement: Procedure for determining positioning accuracy on X- an 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 11.81” (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 partpiece integrity. The precision turret assembly is designed and manufactured by Okuma and achieves an indexing accuracy of +1.5 sec. (0.00008” [0.002 mm]/station).

C-Axis Accuracy

C-Axis positioning: 0.015 ( 0 0’ 54” ) / 30 rotation – Non cumulative C- Axis Repeatability: 0.007 ( 0 0’ 25” )

FLUID SYSTEMS MAXIMIZING METAL REMOVAL AND FLEXIBILITY

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. The system is interlocked, preventing operation if the system faults. Artificial intelligence provides lube only during machine use. Slanted X-axis lube circuits designed to retain lube during idle periods. Z-Axis lube is recovered in a tank at the rear of the machine

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. Heat exchange unit

Chip & Coolant Control Proper chip removal is essential in maximum metal removal conditions. The 30-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.

Separate Coolant tank minimizes heat transfer involved with coolant and chips. The rollaway feature offers quick and thorough tank maintenance. A tank level sight glass is provided for visual control of coolant supply.

The separate coolant tank system comes complete with perforated metal screens and filter unit. An independent 1 hp (0.8 kW) pump unit is standard. A special coolant nozzle provides constant fluid flow at 4 gallons (15 liters) per minute and 100 psi. (7 kg/cm2)* Coolant capacity is 46/52 gallons (175/195 liters).
