Mainly used for drilling tube plate, flange and large plate in petrochemical, boiler, wind power, flange industries and also for connection plates in building, bridge, heat exchange, iron tower industries. Drilling, tapping and light milling for workpieces. The carbide drill can be used for internal coolingÂ high speed drilling, and high speed twist drills can be used toÂ external cooling drilling.
The machine is mainly composed of bed and longitudinal slipway, gantryÂ and horizontal slide table, vertical ram type drilling spindleÂ box, worktable, chip remover, hydraulic system, cooling system, centralized lubrication system, electrical system, pneumatic system and other parts.
1. Heavy-load linear roller guide pairs (HIWIN, Taiwan) are equipped on two sides of the machine bed respectively. The longitudinal movement of the gantry's two sides is driven synchronously viaÂ Panasonic AC servo motor and precise ballÂ screw pair of big pitch.
Â Â Â Â Â Â Â Â Â Â
- Two movable slides are equipped on the cross beam of gantry. The sliders are guided by two linear roller guide pairs and driven by AC servo motor and precise ballsÂ crew pair of big pitch respectively.
- The slides on the cross beam are equipped with vertical CNC feeding ram-type drilling spindle, which adopts special conversion motor with heavy load for spindles. The motor drives the spindlesÂ via synchronous belt, stepless speed regulating, low speed with high torque. The drilling spindles (BT50)Â adopts Taiwan precision spindlesÂ (inner-cooling) withÂ sweep deviceÂ and disk spring automatic broach mechanism, hydraulic cylinder loosing cutter, very convenient to change shank.
- The hydraulic system solenoid valves adopt ATOS of Italy with stable quality.
5. The gantryÂ adopts steel plate welded structure, throughÂ heat aging stress, with stable precision. TheÂ machineÂ bed, worktable, vertical slide board, transverse sliding ramsÂ are all adopt high quality iron castings.Â Â Â Â Â Â Â Â Â Â
6. There are several horizontal T-slotsÂ on the worktable, which are used for clamping clamps and tube plate parts.
Â Â Â Â Â Â Â Â Â Â
- It adopts FAGOR8055 CNC systemsÂ of Spain, equipped with RS232 interface and LCD screen. Drilling coordinate CAD/CAMÂ direct conversion can be realized. With pre modeling and review functionÂ before drilling holes, convenientÂ forÂ operation.
- It is equipped with chain-plate type automatic chip-conveyor and chip collection trolley. The cooling system is equipped with paper filer, high-pressure inner-cooling pump and low-pressure outer-cooling pump, which are used for inner-cooling or outer-cooling of cutter.Â Coolant can be recycled.
9.Â The machine X, Y axisÂ guide railsÂ and lead screwsÂ are equipped with shields.Â X axis is equipped with steel plate protection cover, Y axis is equipped with organ type protective cover
10. In order to ensure the reliability of the machine tools, the key parts are imported with high quality, details see the main configuration list.
11. Workpieces positioning alignment and clamping.
For square workpeice to find the reference block is available on a supporting plate of T slot is fixed on the X and Y in two directions, the reference block square workpiece two adjacent tightly on the side of X and Y on the two direction; for aligning circular workpiece from square workpiece, the two adjacent quadrant reference block stick tight in the X and Y two direction. For easy moving heavy workpieces can be placed in any supporting plate T slot on the center position by edge finder in spindle hole in the measured workpiece diameter (or inner diameter) three points, through the computer CNC program the calculation is accurate and rapid. Workpiece clamping is composed by plate, rod, clamping rod and pad etc., easy to use.
