The three-dimensional drilling adopts three points to control the CNC axis, one CNC detection axis and three drilling spindles with variable frequency and stepless speed, which are controlled by PLC. It has the characteristics of high precision and convenient operation. 3D drilling is an indispensable equipment for quality assurance in steel structure manufacturing industry. What are the components of a 3D drill? < br style = "list style type: none;" / > 3D drilling is composed of main engine, hydraulic system, conveying material channel and electrical control system. < br style = "list style type: none;" / > host: the main engine is the core part of the whole 3D drill. When we use the 3D drill, its operation and rotation are driven by the host. The drilling machine has three power heads, and the holes on the three surfaces can be processed when the workpiece passes through. < br style = "list style type: none;" / > hydraulic system: three power heads can drill holes at the same time, and automatic stroke drilling power head is adopted. It does not need to set the thickness of the workpiece and the length of the drill bit. It can automatically switch between fast forward and work advance, and has high processing efficiency. < br style = "list style type: none;" / > conveying channel: CNC + PLC control, upper computer monitoring, programming software based on Windows platform, programming fast and convenient, preview graphics intuitive. < br style = "list style type: none;" / > electrical control system: spray cooling device is adopted to prolong the service life of drill bit. Each power head is equipped with a spindle reducer motor produced by a famous company. The key hydraulic and electrical components and parts are products of well-known companies at home and abroad. < br style = "list style type: none;" / > the above is about the composition of three-dimensional drilling. Each drilling headstock has hydraulic automatic travel, and there is no need to manually set the effective length of the drill bit and the thickness of the workpiece to be drilled. It can automatically carry out the fast forward work in fast backward switch, which is very convenient.
