CNC Turret Punch Press Machines for High-Precision Sheet Metal Punching

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 CNC turret punch press uses a rotating turret equipped with multiple punching tools to perform high-speed punching, forming, embossing and perforation on sheet metal. The CNC controller positions the sheet precisely under the turret, while the servo or hydraulic system applies the punching force.
STON CNC turret punch presses support continuous indexing, auto-tool switching and high-precision positioning for accurate and repeatable operations.

Turret punch presses are widely used in:

• Electrical cabinets & switchgear

• Metal furniture & office cabinets

• Server racks & telecom enclosures

• HVAC & ventilation panels

• Kitchen equipment & stainless products

• Tool storage cabinets

• Machinery panels & chassis

Any factory that requires continuous sheet metal punching or forming is a suitable user.

Our machines are compatible with:

• Cold-rolled steel

• Galvanized steel

• Stainless steel

• Aluminum

• Pre-painted metal sheets

Thickness range typically 0.2–6 mm depending on the model and tooling.

Turret punching is ideal when you need:

• Embossing, forming, louvers, dimples

• High-speed repeated hole patterns

• Lower operation cost

• Special shapes without expensive laser power

Laser cutting is better for complex profiles, but turret punches excel in forming + speed + cost efficiency.

Yes. STON CNC turret punch presses support:

• Automatic loading & unloading systems

• Robotic sheet handling

• Sorting tables

• Coil-fed systems

• Integration with laser cutting or bending lines

Automation can reduce labor, improve consistency, and run 24/7 in unmanned mode.

Depending on the model, the turret can hold 24–42 tools, including special forming tools.
We support EURO, AMADA-style and custom tooling, including:

• Round

• Rectangle

• Keyhole

• Louvers

• Embossing forms

• Extrusion tools

Our turret punch presses are designed for low maintenance. Typical requirements include:

• Regular lubrication

• Tool sharpening and inspection

• Replacing wear parts on the stripper plate or die

• Periodic servo calibration

We provide maintenance videos, manuals, and remote support.

Selection depends on:

• Sheet size

• Material type & thickness

• Punching frequency

• Forming requirements

• Automation needs

• Production volume

Tell us your sheet size, hole patterns, and annual volume—STON CNC engineers will recommend the most suitable model.
