High Rigid 4 Axis Metal Universal Milling Machinery Cnc Boring And Milling Machines
CNC Floor Type Horizontal boring and milling machine
The CNC Horizontal boring and milling machine are design with large torque, high efficiency, high rigidity and advanced technologies. Per user’s requests, the machines can match with different controllers,different precision requirements, different sizes of tables to form different models of boring machines. This series of boring mills are suitable ‘or machining large, medium sized box shape, frame structure or mould parts, and can perform milling, boring, drilling, winching, tapping etc after one clamping. The machines controls 7 axes with 4 axes simultaneous and allows circular interpolation and 3-D curved surface machining. Equipped with milling head, face plates and other devices, the series of machines have enlarged machining capabilities. The spindle has cooling case to limit the head in spindle.

Machine bed:
The machine bed is built of resin.wood former with reasonable structure and rigidity. It guarantees a sound base and the steadiness of the machine and the stability of column in motion on the bed.there are top quality imported ground hard dent surface racks on the bed, two preload gears co-drive ensures the accuracy of X axis.
Sliding carriage
Built with top quality castings. Resin and wood former, the sliding carriage possesses sufficient intensity. It connects to the machine bed with two wide guide ways. The single guide way serves as main positioning with support from double guide ways to maintain the stability and linearity of column in motion on machine bed.
Column
It is made of high quality casting resin and wood former in a double frame structure, the column is of sufficient rigidity that allows the smooth movement of spindle box vertically. Mosaic type counter weight balance rails are built inside the column to ensure the stability of the counterweight’s vertical movements, thus to ensure the high precision of the machine.
The two ground rails in front of the column check the position of spindle box and ensure the steadiness of the spindle’s vertical movements. The column is equipped with preload precision double nut ball screws and servo motor drives the vertical travels of the spindle box.
Control unit
The operation booth is built with the spindle box, the control unit in the booth fore easy operation . Rota table control panel and the handset unit that allows long distance operation makes the operation simple and efficient.
