The machine is composed of base, gantry, drilling head, CNC dividing head, auxiliary pressing device, support device, tool magazine, chip discharge and cooling system, automatic lubrication and hydraulic system, pneumatic system and electrical system.
a. Drilling head and vertical ram
The drilling head is driven by the variable frequency motor through the belt. The vertical ram is guided by linear roller guide, vertical feed is driven by AC servo motor to drive ball screw pair, and the movement of fast forward / advance / stop / delay is achieved.
b. CNC dividing head
The CNC dividing head is installed at one end of the base of the machine tool, which can move forward and backward to facilitate the loading and unloading of the header. The indexing head is equipped with a customize hydraulic chuck, which adopts a precision slewing bearing with high transmission accuracy and large torque
c. Chip removal and cooling
The gutter under the base is equipped with a flat chain chip conveyor, which can be automatically discharged into the debris carrier at the end. Cooling pump is provided in the coolant tank of chip conveyor, which can be used for external cooling of tool to ensure drilling performance and service life of drill bit. The coolant can be recycled.
d. Lubrication system
The machine tool adopts the combination of automatic lubrication system and manual lubrication to lubricate all parts of the machine too., which avoids the tedious manual operation and improves the service life of each part.
e. Electric control system
The CNC system adopts Siemens SINUMERIK 828d CNC system. SINUMERIK 828d is a panel based CNC system. The system integrates CNC, PLC, operation interface and measurement control loop.
