Description: 2017 Johnford ST40CX with 24" chuck , (only cut aluminum die cast, soft) with Fanuc control, C axis, live tools, no tail stock.The Johnford ST-40CX is a heavy duty, high precision CNC turning center cast from Meehanite iron. Full advantage of the 50HP spindle motor and 4 speed gear box is taken by the one piece, 60 degree slant bed design. Built in classic style, the 60 degree slant bed is a torque tube design. The torque tube, or hole cast through the center of the slant bed, provides an extremely rigid bed and excellent heat dissipation. The square box ways provide the rigidity for heavy duty turning. Hand scraped Turcite - B applied to all mating sliding surfaces ensures high rapid traverse rates and accurate positioning. To ensure precision and thermal stability the headstock, tailstock, and saddle are all mounted on the same plane at a 60 degree angle. The coolant tank is separate from the machine base to prevent heat transfer from the coolant to the machine casting which ensures precision and promotes easy clean out and maintenance. To further ensure accuracy and precision, the ballscrews are double nut type and pretensioned to eliminate thermal growth.The precision spindle structure is mounted using precision double row roller bearings in conjunction with angular contact ball bearings for high rigidity and accuracy. The spindle quill inner and outer linings are precision ground for fit with the spindle, thus ensuring extreme concentricity and accuracy. The spindle is driven by a 50HP high torque motor which provides plenty of power. For applications requiring high torque at low RPM’s, a four speed gear box is standard.A 12 station bi-directional turret or optional VDI turret provides .5 second indexing as well as coolant through the tool holders. A full C axis with live tools is available for applications requiring milling operations. Fanuc CNC controls are standard for performance and reliability.Machine SpecificationsCapacities:Swing over bed/Front cover 40.1"Standard turning diameter 31.5"Swing over carriage 31.5"Maximum cross travel (X axis) 17.7"Maximum longitudinal travel (Z axis) 31.5"Distance between centers 40.9”Spindle:Spindle Motor 50 HPSpindle nose A2-15Spindle RPM 0-1000 (24” Chuck)Hole through spindle 6.0”Bar Capacity 5.47”Spindle bearing diameter 7.87"Spindle inside taper M.T. 7Hydraulic chuck 24” 3-JawTurret:Turret tool positions 12Turret type HydraulicTool mounting Block type or VDIO.D. tool shank size 1.25”I.D. tool shank size 2.0”Index time .3 SecondsBallscrews and axis motors:Z axis ballscrew diameter 50mm (1.98”) x 12 pitchX axis ballscrew diameter 50mm (1.98”) x 10 pitchBallscrew type Class 3 double nut pre-loadedBallscrew mounting type Pre-tensionedX-Z servo motor HP X 5.0 HP, Z 5.0 HPFeeds:Rapid Traverse Rate X,Z 472, 630 IPMCutting feed rate 0.01 - 315 IPMPositioning accuracy +/- .00012" full strokeRepeatability +/- .0001"General:Coolant tank capacity 75 gallonsCoolant pump motor 1.7 HPMachine Weight 25,000 LBSFloor Space 177" X 80" x 86"Machine Power Source 208/220 Volts, 3 Phase 150 AmpsHydraulic pump motor 5HPC axis and Live Tools :Spindle motor 10 HPSpindle RPM 4000BMT tool shank type 50mmC axis accuracy of spindle .001 degreesStandard Machine AccessoriesComplete coolant systemSplash guardsBuilt-in work lightWorkpiece counter1 set of instruction manualsChip conveyor with chip cartSpindle orientation
