Main Castings

• 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: Made of high quality castings, resin and wool former in a double-frame structure, the column is of sufficient rigidity that allows the smooth movement of spindle box vertically. Mosaic type counterweight 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 around rails in front of the column check the position of spindle box and en sure the steadiness of spindle’ vertical movements. The column is equipped with preload precision double-nut ball screws, and servo motor drives the vertical travels of the spindle box.

• Spindle Box: Built with high quality resin, wood former and of box structure.

• Machine Control Unit: The operation booth is built with the spindle box, machine’s control unit is built in the booth for easy operation. Rotatable control panel and the handset unit that allows long distance operation makes the operation simple and efficient.

• Square Ram: Top of ram is built with hydraulic proportional valve for precision compensation of the horizontal movements of ram, and auto compensation for prevention of droop.

• Hydraulic System: There are two hydraulic systems in the machine. The smaller unit is set at the back part cf spindle box and is mainly to control the spindle broach unit and the main transmission gear’s gearshift unit. The bigger hydraulic unit is built in the foundation of the workshop with the machine and supplies all axis with hydrostatic oil and lubricant oil, and supplies spindle with coolant oil.

• The machine’s hydraulic oil runs in enclosed structure and flows back to the tank in the big hydraulic unit.

• Guideway Protection Cover: Y axis gu de way is built with armor type organ shield, the front end of shield is of metal armor structure to prevent burns resulted from chips, other parts of the shield is of organ type structure that relieves the additional load by the spindle’s vertical travels and for easy maintenance. X axis gu de way is built with steel sliding structure shield that includes the return chutes inside the shield to prevent the ship spilling to the return chutes and causing pollution.

Applications

• CNC Floor Boring and Milling Machine can complete drilling, reaming, boring and other hole processing, grooving, plane and surface milling at one time. It can perform angle milling, turning boring and multi-face machining on workpieces mounted on the rotary table. Using the continuous indexing function of the CNC rotary table, it can continuously carry out the processing of space continuous surface (such as impeller), and the machine tool can also carry out the processing of threading, rigid tapping, etc.; the use of milling cutter’s circumferential milling to realize the boring of large holes, etc.; and the processing of various characteristic holes such as circumferential, box-shaped and polar distribution.
