The machine is installed with work headstock and travel head with rotating drilling/boring rod, both workpiece and tool can rotate, and the cutting tool can also be fixed, only feed.
In addition, this machine is also installed a toolpost like that of the lathe, so that the machine adds the function of turning outer circle on the basis of deep hole drilling and boring machine. The machine is a series of products, and can also provide various modified products according to customer requirements.
The machine consists of bed, work headstock, lantern of chuck, open steady rest, stead rest, oil pressure head, vibration damper steady of boring rod, travel head with rotating drilling/boring rod, coolant system, electric system, hydraulic system, chip removing device, lubrication system, turning tool post etc.
the four jaw chuck is installed on the work headstock while drilling, and while boring, two taper plates are used, one is installed on the front end of the spindle on the work headstock, another is installed on the oil pressure head, the taper plates are much more convenient for self-centering, in general condition, the degree of the taper plates is 15°, the detailed requirement of the taper plates is determined by the size of the workpiece. The customer can also choose the other clamp method. There is a taper plate in front of the oil pressure head (oil supply device), and there is a guide bush inside of the taper plates, which is used for guide drilling/boring head, this guide bush must be changed when the cutting tool is to be changed.
