The CNC turret punch press is advanced automated sheet metal punching equipment. With a rotatable turret as the core and multiple dies, it performs punching, forming, and shaping in one setup. Controlled by a CNC system, the turret switches molds seamlessly and moves with the workbench, completing a wide range of sheet metal processing tasks. It is widely applied in machinery, electrical appliances, cabinets, enclosures, and industrial sheet metal fabrication.
The frame adopts a closed “O” structure, welded with high-strength steel plates. After high-temperature furnace tempering, all welding stress is removed, ensuring frame rigidity and long-term stability. The throat design reduces deformation while increasing strength, providing reliable tonnage capacity for heavy-duty punching operations.
Equipped with a turbine worm reducer and double-chain drive, the cutter head achieves stable transmission and precise displacement. The enlarged dual-cylinder design allows synchronous and accurate positioning, reducing side sleeve wear and ensuring high stability in turret punching.
The rotary station is driven by a synchronous belt, delivering high transmission speed, positioning precision, and low noise — ideal for high-efficiency CNC turret punching machines.
Made of 45# carbon steel, quenched and tempered, then CNC-ground for flatness and smoothness. Special fixtures ensure coaxiality of upper and lower dies. Each cutter head passes strict inspection using imported 3D measuring equipment, guaranteeing accuracy in sheet metal punching machines.
The hollow-shaft servo motor directly drives the crankshaft, minimizing connection misalignment. This provides high stability, fast response, and efficient punching. The swing method automatically adjusts angles based on stroke, improving punching speed and precision in CNC punch presses.
The servo motor is cooled by an oil-cooling system, ensuring low temperature rise, high overload capacity, and stable operation. This avoids frequent coolant replacement in cold regions, enhancing reliability of the turret punching machine.
The floating pneumatic clamp provides strong clamping force and stable feeding. Its dovetail carriage ensures rigidity while enabling easy movement. During feeding, the clamp floats automatically, reducing labor intensity and improving material handling efficiency in sheet metal punching machines.
Advanced secondary positioning ensures double accuracy insurance. With real-time monitoring sensors and CNC control, workpieces are repositioned with high precision, eliminating errors caused after first positioning.
When collision risk is detected, the system instantly stops all machine movements. This safety mechanism protects both workpieces and machine parts from damage during CNC punching operations.
Equipped with imported motherboard and motion control card, plus Panasonic RTEX bus servo units, the CNC control system ensures fast communication and closed-loop signal transmission. Multi-axis coordination achieves higher precision in CNC turret punch presses.
The multi-point automatic lubrication system guarantees full lubrication of all moving parts. With copper pipelines instead of plastic, it prevents wear, leakage, and aging, extending the service life of screws, guide rails, and the entire sheet metal punching machine.

A turret punch press is an automated sheet metal punching machine that uses a rotating turret loaded with multiple tools. Through CNC control, the turret switches tools and coordinates with the worktable to complete operations such as punching, nibbling, forming, and embossing in one setup, improving efficiency and precision in sheet metal fabrication.
CNC turret punch presses are widely applied in industries such as electrical cabinets, enclosures, telecommunications, HVAC ducting, metal furniture, and appliance manufacturing. They are ideal for high-precision sheet metal punching machines where flexibility, speed, and repeatability are required.
Turret punch presses excel in fast punching, forming, and embossing operations, which laser cutting machines cannot perform directly. They are more efficient for repetitive hole punching and forming tasks, while also offering lower operational costs for high-volume production. Many manufacturers integrate CNC punch presses with laser cutting for hybrid solutions.
Modern CNC turret punch presses provide high accuracy and consistency, often achieving tolerances of ±0.1 mm. Equipped with servo-driven systems, automatic tool indexing, and advanced CNC control, they ensure stable punching force, precise positioning, and reliable repeatability, even during continuous production.
Turret punch presses improve efficiency by reducing tool change time, supporting multi-station tooling, and enabling continuous punching cycles. With features such as automatic sheet repositioning, floating pneumatic clamps, and CNC automation, they shorten cycle times, reduce manual intervention, and lower labor costs in sheet metal punching operations.
