Description

The Government requires the delivery and installation of a Doosan DBC 130L-II Horizontal Boring Mill. The required period of performance for delivery and installation is within120 days of award of the order. The intent of this Sources Sought is to assess the capability of a contractor to provide, deliver, and install the Doosan DBC 130L-II horizontal boring mill. No deviations to brand, model and specifications will be accepted, as established here in. The required specifications for the Doosan DBC 130L-II Horizontal Boring Mill are as follows: Fanuc 31i-B Controller (15” screen size) and all associated manuals (DVD or CD format.) Chip Conveyer (42” discharge height) Coolant Gun External Air Blow Nozzle Renishaw Radio Interface Kit w/Installation Renishaw RMP60 Spindle Probe, CAT 50 tool shank, 100mm probe stylus and hardware Spindle Probe Calibration Ring Gage Renishaw RTS-AA Touch Trigger Tool Setter Renishaw CAT50 Tool Setter Calibration Master AC spindle motor (37 / 45 kW (49 / 60 hp) 2,500 rpm, 3-speed geared head Big Plus dual contact spindle (Taper and Face contact) Spindle oil chiller Spindle orientation and Rigid tapping Spindle load meter and Spindle override Servo driven tool changer (60 tools) Meehanite cast iron bed Wide, induction hardened and precision ground box guide ways with low friction, fluoroplastic resin mating way surfaces (X - 250 mm \ 9.84", Y - 180 mm \ 120 mm - 7.086" \ 4.72", Z - 220 mm \ 8.66") Oversized, double pre-tensioned ball screws (X - 80 mm (3.15") \ Y - 70 mm (2.75") \ Z-70 mm (2.75") X\Z axis gear reducer for increased thrust and stable feed characteristics under heavy load B-Axis simultaneous 360,000 position rotary table Locating pin for increased accuracy at 90 degrees Fast rapid traverse (10 m/min \ 393 ipm) AICC II (200 block look ahead) Doosan Tool Load Monitoring, Adaptive Feedrate Control and Variable Work Load Control Doosan Thermal Compensation with hardware sensors (Z-axis only) Absolute position glass scales on the X, Y and Z axes 20 bar (230 psi) Through Spindle Coolant, Air Through Spindle Additional M-Codes, 4 ea. Flood coolant with large separate coolant tank and way oil skimmer Semi Splash Guards Telescopic way covers Portable Manual Pulse Generator Program and data protection key switch Metered piston distributor lubrication Work light and 3 color tower signal light Leveling blocks Capacity: X axis horizontal travel - minimum 157.5” Y axis vertical travel - minimum 98.4” Z axis column travel – minimum 78.7” W axis spindle travel – minimum 27.6” Boring Spindle Diameter – minimum 5” Rapid traverse required in X, Y, Z, W (minimum 290 IPM) axis travel Table: A rotary table with minimal dimensions 86 inches x 78 inches Minimum Table load capacity of 33,000 lbs. to handle heavy loads Construction: The bed, column and saddle shall be made from fine grain Meehanite cast iron with heavy ribbing and guide ways for column rigidity. Saddle will be fully supported over the full length of travel. Column to be made from rigid box type casting that is ribbed to prevent twisting and distortion. X axis will be supported by a full casting. Outboard supports will not be acceptable Spindle/Headstock: Ultra precision-paired bearings. A refrigerated spindle oil cooling system. Encoder attach to spindle to allow for rigid tapping. 10-2500 RPM Spindle speed minimum. Spindle Taper will be ISO # 50 40 HP Spindle motor Big plus dual contact spindle (taper and face contact Automatic Tool Changer: Will have auto return and fixed pocket design. Minimum of 40 tools CAT 50 Tool Shank Minimum 5” tool dia. Minimum Tool Length through ATC 23” Motion Accuracy: Cutting Feed 0.040-157 IPM X-axis feed thrust (continuous) minimum 11000 lbs. Y-axis feed thrust (continuous) minimum 16500 lbs. Z-axis feed thrust (continuous) minimum 7500 lbs. Positioning accuracy (full stroke) = +/- .00040 Positioning repeatability = +/- .00020 Least command increment (0.0001) Coolant System: Adjustable nozzles mounted at spindle to provide flood coolant at cutting tip. Through Spindle Coolant, Air Through Spindle Pump pressure capacity – 230 PSI Minimum 100 gal tank capacity Chip Disposal: Wall guarding with visual access door to protect operator Confinement of coolant and chips must be contained to inside the machining area. Coolant gun to access short bursts of coolant for the machine operator. Chip Conveyor for easy chip removal. Oil skimmer External Air Blow Nozzle Hydraulic/Lubrication: Lubrication systems of (all oil types) must be provided to access box ways, ball screws. All motors and pumps and any other systems that require lubrication. Provide metered piston distributors to maintain the correct flow of oil. A low level alarm to prevent the machine from possible damage from restarts Guide Ways: All guide ways will be wide box type, precision ground and induction hardened, and should be fully protected from chips and damage Ball Screws and Axis Drives: Axis drives are to be driven by high precision double-nut ball screws and centered between the guide ways. Ball screws will be supported on both ends by angular contact thrust bearings, and no gears or belts shall be used to help eliminate backlash Power supply: Voltage 205-235V AC 90KVA max Amperage 250 Amps at 208V max Phase 3 Phase Frequency 60 HZ Air Supply Shall not exceed the following compressed air requirements: 19 CFM at 80 PSI Physical Dimensions: Less than 213” in height Less than 319” in length Less than 410” in width Less than 108,000 lbs This is a Non-Developmental Item. The Doosan DBC 130L-II Horizontal Boring Mill is an existing item that is needed to replace in kind the previous HBM lost due to damage beyond repair. Qualification. The Doosan Horizontal Boring Mill must be qualified and demonstrate compliance to the specifications outlined above. Proof of qualification should be addressed in the response.
