Mechanical CNC Turret Punching Machine for Sheet Metal
Poinçonneuse mécanique CNC à tourelle
Mechanical CNC turret punch presses for accurate, efficient sheet metal batch production.
The Mechanical CNC Turret Punching Machine is designed for efficient sheet metal punching, forming, and batch hole-processing applications. With a mechanical flywheel drive, CNC servo control, turret tooling structure, and automatic material positioning, it helps manufacturers improve punching consistency while keeping the machine structure practical and easy to maintain.Compared with a general punch press machine, this CNC turret punch press focuses on automated positioning, multi-tool turret operation, selectable control systems, and stable mechanical impact force, making it a practical choice for buyers who need repeatable punching accuracy and lower operating complexity.

-
Punch head
The fully enclosed oil-cooled stamping assembly is leak-proof, with oil immersion ensuring sufficient cooling and reducing friction. It is integrally connected to the crankshaft of the assembly, resulting in faster stamping response.
-
Turret
Manufactured with precision machine tool standards. The center is aligned with the wheel and perpendicular to the large striking head, ensuring even and stable force distribution and saving energy.
-
Over-tonnage protection
When the pressure exceeds the set value, the impact power is immediately cut off / the safety pin is triggered / the clutch disengages to prevent overload damage to the machine body, crankshaft, gears, and molds.
-
Synchronous belt
The planetary reducer, combined with the double sprocket and double synchronous belt transmission method, makes the cutter head rotation more stable and the displacement accuracy higher.
-
Rotary stations
It adopts a patented worm gear hard connection design with an internal copper shaft structure, which is wear-resistant, low-noise, and features independent control of dual rotary stations, resulting in stronger rigidity and higher transmission accuracy.
-
Patented beam mounting bracket
Patented double-triangular beam mounting bracket. The guide rail, lead screw, and guide rail form a triangular structure, reducing the load on the lead screw, ensuring high-speed, efficient, and stable operation, fast positioning, and low vibration.
-
Double dovetail beam feeding system
The integrated design of the X-axis and Y-axis guideways and lead screws ensures precise material handling. Pneumatic clamps enhance stability. Multi-point automatic lubrication ensures adequate lubrication and reduces wear.
-
Double chain drive mold system
The entire system uses dual-chain drive, which minimizes the likelihood of equipment failure caused by chain loosening and increases the chain tensioning cycle to more than one year.
-
Mechanical drive
A proprietary flywheel system provides stable power, reduces motor load, and ensures high-speed continuous production. The flywheel design minimizes energy consumption while maintaining stable operation.
-
Electrical accessories
Panasonic and Siemens electrical appliances and accessories from Japan are highly impact- and vibration-resistant, making them suitable for high-frequency impact processing in mechanical punch presses, and they have a low failure rate during long-term continuous operation.
-
Stainless steel edged countertop
It is wear-resistant and corrosion-resistant, not easily scratched or damaged, ensuring the surface quality of the workpiece, easy to clean and with a longer service life.
