Heavy Processing Capabilities

Oturn heavy-duty CNC milling and drilling machines feature heavy-duty cast iron bases and extremely powerful spindles. Ribbed core castings enhance rigidity and thermal stability, reduce distortion, and enhance vibration damping. They are ideal for precision machining of large, heavy materials.

High Operating Efficiency

Our heavy-duty CNC milling and drilling machines are equipped with high-power spindles that deliver higher torque. This gives them greater flexibility when machining large workpieces without compromising accuracy, allowing them to complete tasks quickly. This helps you optimize material removal rates and maximize CNC machining efficiency.

Long Service Life

Designed to withstand long-term heavy-duty cutting loads, Oturn heavy-duty CNC drilling and milling machines are rugged and durable, featuring a nickel-plated surface for rust resistance. They’re fully shielded to prevent chip and coolant splashes, protecting the machine’s delicate internal components. This means you can rely on them for decades.

Safe and Reliable

Oturn heavy-duty CNC milling and drilling machines offer exceptional clamping force, effectively preventing micro-movement caused by vibration. Our innovative design also eliminates rigid impact during clamping. Our machines are highly reliable, requiring minimal operator intervention, ensuring worker safety.

Automatic Chip Removal

Our heavy-duty CNC drilling and milling machines feature an automatic chip conveyor at the rear of the worktable and a filter at the end. Oturn led the way in chip conveyor design, handling capacity, wear resistance, matching filtration levels, and intelligence. This is crucial to ensuring your machine’s core strengths are fully utilized.

Fast Response Time

Our heavy-duty CNC drilling and milling machines provide exceptionally fast response times, with an opening and closing time of just 0.06 seconds. This rapid response effectively protects the machine and extends the life of the lead screw. Choosing us will ensure you maintain high performance over time, without the worry or effort of a single machine.

Fast Cycle Times

The combination of a large-capacity worktable and a high-powered spindle ensures Oturn heavy-duty CNC drilling and milling machines can complete machining tasks in record time. This minimizes downtime, making them a powerful tool for rapid, high-volume production of heavy parts.

Flexible Customizability

To meet your diverse workpiece processing needs, Oturn manufactures a wide range of standard heavy-duty CNC drilling and milling machines. If your industry requires specialized workpieces that aren’t met by standard models, we offer highly flexible custom solutions. We believe you’ll be satisfied with our competitive price.

When facing extremely harsh environments, standard heavy-duty CNC drilling and milling machines may not be able to meet all your needs. Oturn can replace some parts with special materials or special functions according to your needs.You can easily get them here.

Oturn heavy-duty CNC drilling and milling machines are equipped with high-capacity, ultra-fast tool changing systems. These systems adapt to a variety of machining scenarios and effectively reduce manual intervention. Systems that support continuous and high-intensity tool changing can significantly optimize your overall machining efficiency.

• Precise tool identification and tool placement
• The CNC machine comes standard with a 24-tool magazine
• Upgradeable to a 40- or 60-tool magazine
• Quick tool change time of 5 seconds 

We provide three heavy-duty CNC drilling and milling machine models with standard specifications. They’re suitable for machining parts of varying sizes and weights. If none of these models perfectly suit your needs, contact us for a custom design.

Worktable type heavy-duty CNC drilling and milling machine

• Workbench load capacity: Maximum 5000kg
• Maximum speed: Up to 3000 RPM
• Core advantages: They offer excellent structural rigidity, relatively easy to control thermal deformation, and generally provide the highest positioning accuracy and repeatability.
• Application scenarios: They are suitable for applications requiring relatively controlled dimensions and high precision, such as automotive transmissions, engines, and aerospace structural parts.

Moving column type heavy-duty CNC drilling and milling machine

• Worktable load capacity: Maximum 8000kg
• Maximum speed: Up to 4500 RPM
• Core advantages: They enable rapid multi-position hole machining and milling on long workpieces, facilitating the lifting, positioning, and clamping of large workpieces.
• Application scenarios: They are suitable for machining long, wide plates and structural components such as wind turbine flanges and large drive shafts.

Floor-standing type heavy-duty CNC drilling and milling machine

• Worktable load capacity: Maximum 30,000 kg
• Maximum speed: Up to 3,000 RPM
• Core advantages: They can handle extremely heavy workpieces and possess exceptional rigidity and stability.
• Applications: They are suitable for machining extremely large and heavy workpieces in industries such as aerospace, energy, and shipbuilding.

Both drilling and milling are the most basic and widely used machining processes. Drilling is to create a round gap in the workpiece. The main role of milling is to subtract material from a workpiece so as to realize a lot of different kinds and options, now not simply holes.

Conventional heavy-duty CNC drilling and milling machines can complete drilling work to a depth of 10 times the drill diameter, while high-end deep hole heavy-duty CNC drilling and milling machines can achieve drilling work to a depth of 30 times the drill diameter.

Performing both drilling and milling on the same CNC machining center is a core efficiency strategy for modern manufacturing. Our heavy-duty CNC drilling and milling machines reduce setups and manual intervention, while improving precision and consistency. Ultimately, you can significantly increase production speed, reduce costs, maintain quality, and enhance production flexibility.

As high-precision, high-stability machining equipment, heavy-duty CNC drilling and milling machines are easier to maintain than traditional equipment. With proper care, they can maintain 95% accuracy for over 50,000 hours of operation.

You should check the coolant level and hydraulic pressure daily, and the chip conveyor and guideways weekly. For heavy-duty CNC drilling and milling machines used continuously, it’s best to regularly test spindle runout, change guideway lubricant, and check alignment. If you’re unsure how to do this, please contact us and our after-sales team will provide maintenance training.
