CNC BORING & MILLING MACHINE

CNC BORING & MILLING MACHINE       I.                  Machine Usage:

This CNC GANTRY TYPE BORING & MILLING MACHINE WITH MOVABLE WORKING TABLE, is suitable for drilling, milling, and boring on plates or cased beams. This machine is easy to operate, can enhance production efficiency a lot. This machine is flexible machinery equipment, suitable for kinds of middle or small production.

II.               Machine Structure and Configure:

Machine consists of mainframe, working table, fixing gantry, cross slide carriage, boring and milling unit, auto chips cleaner, circulatory cooling equipment, electrical system and so on.

The mainframe is 7585mm long, 2310mm wide and 860mm high, is a weldment steel structure under stress removing by artificial aging, with cased construction design and close ribbing support.

The working table is casting machinery with stress removing by artificial aging and secondary stress removing after semi-finishing, with stable processing accuracy. There is T type groove on it, which is suitable for workpiece positioning and clamping.

There are three multi-slide block heavy linear guide on mainframe, the working table can move longitudinally along guide. There are nuts for adjustment on the base of machine body, which can adjust the level of working table conveniently.

Clear width of gantry is 2500mm, the beam and column of gantry are both casts treated by artificial aging, and in front of beam there are two high bearing roller linear guide sets with the distance of 720mm and step distance of 250mm between them.

The power unit adopt precision spindle from Taiwan, which is driven by spindle servo though ZF bipolar reducer and notched belt. Spindle is BT50 taper hole. Z axis adopts double oil cylinder balance, and equipped another pressure reservoir for supplying required pressure quickly, to make the up and down moving of Z axis be stabler.

There are screw chips cleaners at both sides of working table to feeding processed swarf to the chain-plates type transporter at front, and by this ejected to swarf cart conveniently. The chain-plates type transporter equipped in the circulatory cooling tank, and at the end of cooling tank theres one set of water pump connected with power units cooling system by glue pipe to supply cooling fluid during working.

Using Mitsubishi M64S CNC system, colorful screen, Chinese operation interface, input workpiece data by external PC or at site, and easy to operate.

In order to guarantee the reliability and wear of machine, the linear guide, ball screw, servo motor, driver, precision spindle, ZF reducer, towline, and so on electrical components of this machine are all imported products with high quality.
