Clean holes and precise shapes are essential for downstream assembly, coating and long-term product performance. The STON CNC turret punch press uses rigid structures, servo control and high-quality tooling to minimize burrs, deformation and dimensional deviation. Accurate coordinates and repeatable positioning help avoid fitting problems in later bending, welding and installation processes, reducing rework and quality complaints.
The Punch Laser Combined Machine achieves seamless integration of stamping and laser cutting, allowing punching, forming, rolling, tapping, and cutting processes to be completed in a single setup. This not only improves sheet metal utilization and processing capacity but also supports flexible small-batch, multi-variety production. It is an ideal solution for modern CNC punching and sheet metal fabrication.
The machine adopts a welded and stress-relieved frame to withstand high-speed punching forces. Precision linear guides and slides support smooth ram motion, ensuring accurate tool alignment and stable punching quality throughout the machine’s service life.
A robust turret with multiple stations holds a wide range of punching and forming tools. Quick-change tool holders and indexable stations shorten setup time. Round, oblong, square and special-shape tools can be arranged to match your typical part requirements.
Programmable clamps grip the sheet firmly while allowing automatic repositioning for large-format parts. Brush or ball tables reduce friction and protect the sheet surface. Optional repositioning devices help process plates larger than the standard X-Y stroke.
The punching unit provides powerful and stable force for clean hole edges and long tool life. Servo or hydraulic technology is selected according to model and application needs, ensuring efficient energy use and smooth punching performance.
The electrical cabinet integrates CNC control, servo drives, PLC and safety modules. The control system manages axis motion, turret indexing, tool selection and punching sequences, providing alarms and diagnostic information to support daily operation and maintenance.
Key moving parts are equipped with centralized or automatic lubrication to minimize wear. Maintenance points are easy to access, allowing your technicians to complete regular inspections and servicing quickly, keeping the turret punch press in reliable condition.

A CNC punch machine is a sheet metal punching machine that uses computer numerical control to drive a turret press. It can perform punching, nibbling, forming, and embossing with high precision. By rotating the turret equipped with multiple dies, the machine quickly switches tools to process different shapes on sheet metal efficiently.
CNC punch presses are suitable for a wide range of sheet metal materials, including stainless steel, aluminum, cold-rolled steel, galvanized steel, and coated sheets. With proper tooling, the CNC punch machine ensures clean edges, consistent punching depth, and accurate forming for diverse industrial applications.
Compared with manual punching or older mechanical presses, a CNC turret punching machine offers:
Higher punching speed and repeatability、Reduced setup time with automatic tool indexing、Lower error rates and consistent quality、Compatibility with automated sheet handling systems
This improves overall productivity and lowers the total cost of ownership.
CNC punching machines are widely used in industries such as electrical cabinets, HVAC ducting, kitchenware, telecommunications enclosures, automotive sheet metal parts, lighting equipment, and furniture manufacturing. They are ideal for both small-batch custom orders and large-scale sheet metal production.
When selecting a CNC punch machine, consider:
Sheet size and thickness capacity、Turret configuration and number of stations、Punching speed and stroke frequency、Automation options (loading/unloading, sorting)、Brand reliability and after-sales support
Evaluating these factors ensures the machine meets your current and future production needs.
It is ideal for parts that require many holes, slots, louvers or special shapes, such as electrical cabinet panels, ventilation ducts, lighting fixtures, metal furniture and appliance components.
For parts with a large number of standard holes and repeating patterns, a turret punch press is often faster and more economical than laser cutting. It can also perform forming operations such as louvers and embossing, which lasers cannot do directly.
Typical models process thin to medium-thickness carbon steel, stainless steel and aluminum sheets. The exact capacity depends on the configuration; we will recommend a model based on your material, thickness and product types.
The number of stations depends on the model and turret design. A combination of fixed and indexable stations can be used to hold round, oblong and special-shape tools. We will help configure the turret according to your part drawings.
Yes. It can be combined with loading/unloading systems, storing towers, laser cutting units and panel benders to form a flexible sheet metal production line.
STON offers machine commissioning, operator training, remote support, spare parts supply and on-site service when necessary. Our goal is to keep your turret punch press running efficiently for many years.
Whether you're upgrading an existing line or starting a new project, STON will customize a CNC solution for your production.
