Description

Power Heads and Worktable:The two power heads are independently configured to support parallel processing, with a maximum drilling diameter of Φ30 mm. The worktable is hydraulically clamped automatically. The rotary axis (C - axis) and the vertical axis (Z - axis) are numerically controlled for linkage, which is suitable for 360° circular drilling. Feeding System:The Y - axis stroke is 180–260 mm, and the rapid movement speed is 8 m/min, which is suitable for quick positioning.
Dual Spindle Flange-Specific High-Speed CNC Drilling Machine

Features

Efficient cooperation of dual spindles

The independent dual power heads perform synchronous processing, increasing the efficiency by 50% and meeting the requirements of mass production

High - Pressure Cooling Technology

With an internal cooling pressure of 2×1.5 MPa and in combination with BTA drills, the chip removal efficiency is increased by 40%.

Intelligent Control

PLC centralized control + CNC axis linkage ensures a hole position accuracy of ±0.1 mm and reduces manual intervention.

Compact Design

The machine tool has a small footprint (TDS500/2: 2700×2000 mm), which is suitable for limited workshop space.

Working Principle

Dual Spindle Flange-Specific High-Speed CNC Drilling Machine
Dual Spindle Drive:The dual spindles are independently controlled by servo motors, with a speed range of 10–4500 rpm, which is suitable for drilling different materials.The high - pressure internal cooling system (2×1.5 MPa) is used in conjunction with carbide drills to extend the tool life. CNC Linkage:The C - axis (worktable rotation) and the Z - axis (vertical feed of the spindle) are linked to achieve automatic machining of circular holes.The Y - axis has a rapid positioning speed of 8 m/min, which shortens the non - cutting time. Accuracy Assurance:The CNC system integrates backlash compensation to ensure a hole pitch accuracy of ±0.1 mm.

Application & Case

Flange Manufacturing: Precision drilling of multiple workstations on flange sealing surfaces and bolt holes.

Petrochemical Equipment: Machining of positioning holes on valve flanges and tube sheets.

General Machinery: Synchronous machining of multiple holes on gear discs and bearing seats.

Mold Industry: Efficient machining of cooling holes and positioning pin holes on mold plates.

FAQ

Yes, but custom fixtures and programming are required (workpiece drawings are needed).
It is recommended to replace the coolant filter element every 400 hours and clean the internal cooling pipeline every 1500 hours.
The maximum thickness of the standard model is 50 mm, and that of the customized model can be extended to 80 mm (the Z - axis stroke needs to be adjusted).
