Three-Dimension Bohrmaschine Type SKHMZ3

I. Brief Introduction of the MachineThe structure of the machine is rollers' conveying and gantry moving in a small range. The gantry structure and base are plate style box-beam structure.It's mainly used for drilling of three-dimension multi-hole of H-beam. Three axes simultaneous machining may be realized. The accurate CNC system and fine mechanical performances may meet the accuracy requirements for the dimensions of one group of holes accurately.II. Main Technical ParametersThe max. machining capability of the drilling machine: Drilling diameter: 13 -40mm Gantry moving range: 2000mm The range for the height of H-steel: 2 00 -800mm The range for the width of H-steel: 200 -1200mm The range for the max. length of H-steel: 5000 -15000mm Motor power of spindle: 3×4KW Taper of drill rod Morse 4 The max. up-and-down speed of cross drill: 500mm /min Hydraulic feeding: Pressure in hydraulic system: 10Mpa Cooling mode: Atomized cooling Total input power: 26 KW Weight of the complete machine: 8000kgIII. Characteristics of the MachineThe machine uses the computer and accurate and reliable driving mechanism and replaced the primitive method of re-aligning and clamping for second time positioning after drilling in single direction. The positioning accuracy of machining of holes on mutual vertical plane is improved and the working efficiency is greatly increased at the same time.IV. Structure and CompositionThe machine is adopted with steel box-beam structure. The gantry is stable in structure and high in strength. The spindle box is controlled by computer and the spindle motor is adopted with four governing modes.The workpiece is clamped hydraulically.General lay-out will be according to the length of H-beam to be machined by users, and concretely design the lay-out of the relative clamping and aligning device and conveying rollers and set the relative dimensions.V.
