Machine Features

This machine has bed table, moving columns and beam frame, moving saddle and ram, drilling power head, automatic lubrication unit, covers, coolant system, CNC system, electrical system, etc.  Precision guide ways and ballscrews are used to achieve good positioning and repeat accuracy.

1.  Bed Table: made of robust one-piece iron casting, 2^nd time heat treatment and precision machined.  Two Columns are moving along X axis on the bed, driven by AC servo motors/ball screws on two sides.  Machine foot has screw hole for machine leveling easily.

2. Moving Portal Frame: has linear guideways and ballscrew on the front face of the beam, with servo motor to drive the saddle travelling in Y axis.

3. Ram slide: is made of iron casting, with two sliding guide rails, ballscrew, driven by servo motor and speed reducer, to make the drilling head moving in Z axis, with motions of rapid feed, work feed, rapid return, and stop, with function of automatic chip cut-off, chip withdraw, pause.

4. The drilling head: is equipped with servo spindle motor, with tooth-belt driving to spindle. The spindle has three row bearing in front and two row bearing at back end.  Spindle is equipped with pneumatic cylinder for tool clamping/unclamping.   BT40 spindle with high speed rotary union is used, which can use high speed U drill with coolant through the tool.

5. Automatic lubrication unit and covers: the guide ways, ballscrews, and transmission systems are with automatic lubrication.  The X/Y axes are with covers, and table is surrounded with splash guard.

6. CNC function:
6.1 Chip cut-off function, with which the chip cut-off time and cycle can be set in the man-machine interface.
6.2 Tool retracting function, with which the tool retracting height can be set in the man-machine interface, so that when the drill reaches such height, the drill head will retract to the position above the work piece, and make chip removed by drill rotating, and then rapid feed to the drilling position and then continue with work feed.
6.4 Drill position simulation function to check program before cutting.
