Product Name: Bed Type Milling Machine, Table 2100x500mm, Heavy-Duty (BM2100x500) Model NO.: BM2100x500 Precision: High Precision Automatic Grade: Semiautomatic Controlling Mode: Artificial Structure: Bed type Type: Worktable Milling Machine Worktable Size: 2100x500mm Milling Head Motor: 7.5kw Product Description 1. Bed-type milling machine with large capacity for milling large parts and heavy machining. The extremely rigid large box-column, made of high-density and close-grained premium grey cast iron, provides a rigid machine base for performing stable and precision cutting even at very worktable loads; 2. The large worktable 2100x500mm worktable on this bed-type milling machine travels only in the longitudinal direction (X-Axisi) and in the cross direction (Y-Axis). Combined with the powerful universal swivel milling head (fitted with 7.5 KW motor) which travels in the vertical direction (Z-Axis), the worktable allows the bed-type milling machine to carry a single large&heavy workpiece or multiple workpiece in a single set-up and take heavy cutting with high precision and stability even at very high table loads;3. The universal swivel milling head on this bed-type milling machine features high cutting power, maximum rigidity and performs quiet operations. The angle of its position can be set manually on a infinitely adjustable scale from 90º to 45º, therefore the milling head can be adjusted easily to any user-defined spatial angles or horizontal position. Benefitting from its high rigidity, this bed-type milling machine can take both vertical milling and horizontal milling with high stability, low vibration, increased machining precision and very high table loads;4. A horizontal cutter arbor supporter is provided with this bed-type milling machine. It has excellent rigidty, allowing the user to fully utilize the advantages of this bed-type milling machine for machining with long horizontal cutter arbors.5. Extra wide box guideways on X and Y axes ensure maximum rigidity and precision at high table loads;6. All gears, shafts and guideways on this milling machine have been high-frequency hardened and precision ground for lasting precision;7. Infinitely variable feed on all X, Y, Z axes;8. A 3-axis digital readout position indicator is assembled with the machine, ready for operation to ensure high operating accuracy;9. Control panel is mounted on an extending arm and can be positioned as per the ease of operator.Standard accessories:1) 3-Axis digital readout as position indicator;2) Universal swivel milling head;3) Cooling system;4) Draw bar;5) 1 Set of ISO 50 milling chucks (8 Pcs of collets Ø4,6,8,12,16,18,22,26mm);6) Horizontal milling cutterarbor Ø40mm;7) Horizontal milling cutter arbor Ø32mm;8) Horizontal milling cutter arbor supporter;9) 7:24 Taper sleeve ISO 50/MS 4;10) Work lamp;11) Operating tools;12) Foundation bolts M12 x 500 mm;13) Operation manual.Optional accessories:1) Milling chucks;2) Machine vises;3) Reduction sleeves;4) Tailstocks for rotary tables; 5) Rotary tables;6) Dividing heads;7) Angle plates.SpecificationsUnitBM2100x500Worktable size, L x Wmm2100x 500T-slots on worktableNumberNos.4Widthmm20Pitchmm100Maximum load of worktableKG2000Worktable travelsLongitudinal (X-Axis)mm1500Cross (Y-Axis)mm670Milling head travelVertical (Z-Axis)mm670Spindle taperISO 50, 7:24Spindle speed range60 Hz motorRPM40 - 1600, 12 Steps50 Hz motorRPM35 - 1345, 12 StepsDistance between spindle centerline and vertical guideway surfacemm610Distance between spindle nose and worktable top surfacemm0 - 670Feed speedsLongitudinal (X-Axis)mm/Minute20 - 1800,SteplessCross (Y-Axis)mm/Minute20 - 1800, SteplessVertical (Z-Axis)mm/Minute10 - 900, SteplessRapid traverse speedsLongitudinal(X-Axis)mm/Minute3500Cross (Y-Axis)mm/Minute3500Vertical (Z-Axis)mm/Minute1750Main motor powerKW7.5Feed motor powerKW2Headstock elevating motor powerKW2Cooling pump motor powerKW0.55Machine sizecm330 x 238 x 275Machine packing sizecm228 x 228 x 282Machine net weight / gross weightKG7300 / 8000
