Here we give you suggestions how to choose CNC plate drilling machine model according to different industries.

1) Steel structure, steel tower plate processing:

a. Normal speed (to 560rpm): CJZ series.

b. High speed economical type (to 3000rpm):

CJHZA series, JNYO spindle, max.drilling diameter 50mm.

CJHZB series. JNYO spindle, max.drilling diameter 40mm.

c. High speed type (6000rpm):

KENTURN spindle BT40, max. drilling diameter 40mm, with ATC (for selection), has drilling, tapping, milling functions etc.

2) Petrochemical industry tube sheet processing:

Large quantity of holes, diameter 10-30mm, thickness 100-300mm. Sometimes need milling groove on tube sheet.

a. GZP series: worktable and machine frame are separated, better absorbs vibration force during high speed processing. BT50 spindle, Max. drilling diameter 90mm.

b. GZC series: BT50 spindle, Max. drilling diameter 90mm.

c. CJHZ series: BT40 spindle. Max.drilling diameter 40mm.

3) Nuclear Heat exchanger, Tube plate processing:

WZ series CNC horizontal drilling machine is suitable. Because this machine structure can ensure better chip removal effect.

4) Boiler industry Tube plate processing:

Before boiler industry adopted coal burning, max. hole diameter for tube plate is 50mm. Nowadays, gas boiler is more popular, max. hole diameter is 76mm.

GZP or GZC series: high speed drilling type.

DZC series: normal speed drilling type.

5) Paper making, pharmaceutical industry plate processing:

Large quantity of holes, and large density, relatively small diameter. A high efficiency processing equipment is required.

CJSZ series: for pulp or particulate filtration. Spindle rotation speed to 4000rpm.
