The turret is integrated with multiple sets of dies of different specifications. With the help of the CNC system, the turret die change and the X/Y axis movement of the worktable can be precisely controlled to efficiently complete various processes such as punching, trimming, and shutter forming. Compared with the servo type, it is a more economical choice.

A turret punching machine is a type of sheet metal punching equipment that uses a rotating turret with multiple tool stations to perform a wide range of punching operations. Compared with traditional punching presses, a CNC turret punch press offers faster setup, higher accuracy, and better adaptability to complex designs.
Brush + ball table and pneumatic clamps prevent scratches and deformation during punching.
Stress-relieved welded frame keeps accuracy and extends machine & tool life.
Flywheel + clutch design saves energy and ensures stable, easy-maintenance operation.
Multiple punch tools handle varied hole shapes and sizes for flexible applications.
X/Y guides with pneumatic clamping ensure stable positioning and repeatability.
Processes mild steel, stainless, galvanized, and aluminum with ease.
Our CNC punching machines and sheet metal punching machines are widely used across multiple industries, delivering precision punching, nibbling, and forming for various materials.
Explore key components of our CNC turret punching machine, from rigid O-frame to precision tooling, ensuring high accuracy, durability, and efficiency for all sheet metal punching applications.
O-type closed welded press frame with stress relief treatment. High rigidity ensures long-term accuracy, extends machine and tooling life, and improves positioning precision for sheet metal punching.
Mechanical drive mode, through the main motor to drive the flywheel rotation, the use of flywheel inertia stamping, stamping control by the clutch, simple structure, low product price, stable performance, simple and convenient maintenance.
Worm gear structure for accurate bi-directional transmission. Synchronous belt drive maintains perfect alignment between upper and lower turrets for precise punching.

Our machines is suitable for common sheet metals such as stainless steel, carbon steel, aluminum alloy, and galvanized sheet. The thickness range is 0.2mm-6mm, meeting needs of various industries, including home appliances, hardware, and cabinets. It also supports asymmetric and complex customized processes.
Yes, we offer a one-stop service: “on-site installation + commissioning + customized training.” Professional engineers will visit the customer’s site to complete production line assembly and equipment integration commissioning to ensure the line reaches its designed capacity. We also provide theoretical and practical training for operators (6-8 days), covering equipment operation, routine maintenance, and troubleshooting. After the training, we provide an operator manual and video tutorials.
Customized services are available. We will optimize the machine structure based on the customer’s workshop space, load capacity, and processing requirements. While ensuring processing accuracy, we adapt the machine to the shop’s existing power and air supply conditions to ensure smooth installation and efficient operation.
We have established a 24-hour global after-sales response mechanism: Customers can submit troubleshooting reports via phone, email, or online customer service, and a preliminary solution will be provided within 1 hour. If remote debugging is required, an engineer will provide video guidance within 2 hours. For hardware repairs, domestic customers will receive a visit within 48 hours, while overseas customers can use authorized service centers or expedited delivery of parts (with installation instructions) to ensure a quick resolution.
All of our standard equipment (flexible bending centers, CNC turret punch presses, press brakes, and punching and shearing machines) comes with a one-year free warranty. For some products with higher system complexity, the warranty period can be extended to 18 months. The warranty covers repair and replacement of quality issues with core components (such as servo motors, CNC systems, and guide rails), as well as free on-site inspections during the warranty period. Please note that equipment failures caused by human error, force majeure (such as floods and earthquakes), or failure to follow the maintenance manual are not covered by the free warranty, but paid repair services are available.
Extended warranties are available, with coverage ranging from 1 to 3 years. These plans are customized based on the equipment type, frequency of use, and customer needs. A one-year extension for a single device costs approximately 3%-5% of the total price, while bulk extensions for multiple devices or fully automated production lines offer a 20% discount. During the extended warranty period, in addition to core component repairs, customers also receive a free annual comprehensive equipment inspection and maintenance service to help them proactively identify potential faults and extend the life of their equipment.
We offer flexible payment options to meet the needs of domestic and international customers: ① Telegraphic Transfer (T/T): 30% prepayment, 70% before equipment leaves the factory; ② Letter of Credit (L/C): We accept irrevocable letters of credit issued by the customer’s partner bank at sight to ensure the security of funds for both parties. All payment methods comply with international trade practices and support mainstream settlement currencies such as the US dollar and the euro.
A turret punch press uses a multi-station turret to switch tools quickly, while a CNC punch press adds computer control for automated, precise punching.
It handles stainless steel, galvanized sheet, cold-rolled steel, aluminum, and coated plates.
Our machines achieve positioning accuracy within ±0.05mm for consistent punching results.
Yes, we offer flexible turret configurations (24–48 stations) based on customer needs.
They are widely used in electrical cabinets, HVAC, kitchenware, enclosures, lighting, and industrial sheet metal production.
Whether you're upgrading an existing line or starting a new project, STON will customize a CNC solution for your production.
