Overview

The PHM3030/2 Gantry Movable CNC Plate Drilling Machine is a high-precision solution designed for drilling tube sheet plates and flanges (max hole diameter: φ80mm). It combines drilling, reaming, boring, tapping, chamfering, and milling in one system, catering to the diverse needs of heavy industries. Compatible with both carbide drill bits and H.S.S. drill bits, and powered by the Siemens 828D CNC system, this machine ensures exceptional accuracy and ease of use for large or thick workpieces.


Small-Size Gantry CNC Plate Drilling Machine PHM3030/2


Key Features & Benefits

Large Processing Capacity

It handles plates up to 3000×3000mm (L×W) and 250mm thick, with a worktable loading capacity of 3ton/㎡. This makes it ideal for processing large workpieces like boiler tube sheets and wind power flanges without size restrictions.

Dual Cooling for Tool Longevity

The inner cooling + outside cooling system delivers 2MPa pressure and 50L/min flow rate, effectively reducing tool overheating during high-speed drilling. This extends drill bit lifespan by 30% and maintains consistent processing quality.

Precise Positioning & Stability

With X/Y axis positioning accuracy of 0.052mm/full travel and repeatable positioning accuracy of 0.033mm/full travel, the machine ensures precise hole alignment—vital for flange sealing and tube sheet assembly. The gantry’s dual-servo drive (X axis: 2×3.3kW motors) guarantees stable movement even at maximum travel (3000mm for X/Y axes).


Core Components & Quality Assurance

Premium Core Parts

Siemens 828D CNC System: Offers user-friendly operation and reliable execution of complex drilling programs.

BT50 Drilling Spindle: Ensures high rigidity and easy tool changes, streamlining workflow transitions.

AirTAC Pneumatic Components (Taiwan): Maintains stable 0.5MPa pressure for workpiece clamping and auxiliary functions.

Certification & Free Accessories

Certified by SGS to meet international standards, the machine comes with free accessories: 1 optical edge finder, 1 set of inner hexagon wrenches, 3 tool holders & pull studs (Φ40-BT50 ×2, Φ20-BT50 ×1), and 2 kegs of spare paints, supporting quick setup.


Application Scenarios

The PHM3030/2 is widely used in heavy industries such as:

Boiler & Heat Exchanger Manufacturing: Drills precise holes in tube sheets for tight tube connections and efficient heat transfer.

Wind Power Flange Processing: Delivers accurate multi-hole drilling for wind turbine flanges, enhancing outdoor stability.

Bearing Manufacturing: Performs precision boring and tapping to meet strict tolerance requirements for bearing housings.
