High Speed CNC Metal Plate Drilling Machine Model PMZ2020H

Product feature：
1. Heavy-load linear roller guide pairs are equipped on two sides of the machine bed respectively. The longitudinal movement of the gantry’s two sides is driven synchronously via AC servo motor and precise ballscrew pair of big pitch.

2. Two movable slides are equipped on the cross beam of gantry. The sliders are guided by two linear roller guide pairs and driven by AC servo motor and precise ballscrew pair of big pitch respectively.

3. The slides on the cross beam are equipped with vertical CNC feeding ram-type drilling spindle, which adopts special conversion motor with heavy load for spindle. The motor drives the spindle via synchronous belt. The drilling spindle adopts Taiwan precision spindle (innercooling) with disk spring automatic broach mechanism, hydraulic cylinder loosing cutter, very convenient to change shank.

4. The machine is equipped with hydraulic system to finish the hydraulic balance of vertical ram and hydraulic cutter loosing of spindle.

5. It adopts  CNC system of Spain, equipped with RS232 interface and LCD screen. The automatic programming provided can not only generate processing programs automatically, but also preview hole position before drilling.

6. It is equipped with chain-plate type automatic chip-conveyor and chip collection trolley. The cooling system is equipped with paper filer, high-pressure innercooling pump and low-pressure outer-cooling pump, which are used for inner-cooling or outer-cooling of cutter.
