The Oturn CNC boring and milling machine is equipped with a high-precision servo motor control system. The boring spindle and the boring head spindle are both driven by high-performance servo motors, providing accurate control of speed and position. This is in line with high stability and repeatable positioning accuracy during machining.

Besides, the spindle and end face head spindle are equipped with AC servo motors, achieving a balance between high torque and high speed to drive the spindle running smoothly and efficiently, enhancing overall machining quality and production efficiency.

Employing servo motors makes the most of machine tool dynamic response, significantly saving equipment wear and energy, and supporting the achievement of intelligent, high-efficiency manufacturing.

The Oturn CNC boring and milling center is equipped with an advanced spindle box construction, with a big flat rotary table at the rear, which enables efficient boring and milling of deep holes and flat surfaces to meet the different requirements of complex workpieces. The spindle box possesses a counterweight balancing system, along with an AC servo motor, to precisely control the spindle and face milling head for silky smooth and efficient machining operations.

The ram is driven by a hydrostatic pressure pad with a dedicated direct-drive boring bar and high-accuracy feedback system, automatically compensating for temperature-induced length errors to provide maximum machining accuracy and rigidity. In addition, the spindle housing also features high-damping structure at the position of the vibration source, efficiently damped vibration and improved surface quality and tool life.

These technical advantages provide Oturn spindle housing a solid foundation to achieve high precision, stability, and efficient production, which can help you achieve competitive success in business.

The Oturn CNC milling and boring machine adopts a 4×90° four-point manual single-pin positioning structure to ensure precise and stable positioning for meeting multi-angle milling requirements. The rotary worktable ensures any-angle positioning, and there is a hydraulic braking system to ensure stable clamping, which enables flexible and safe angle positioning to enhance machining flexibility.

Equipped with a high-precision circular encoder angle positioning system, the positioning precision can reach as high as ±4 arc seconds, allowing precise execution of each process. Safety devices can monitor the material feeding status intelligently and automatically interrupt the machine under overload to protect workpieces and tools from damage.

Due to its ample load-bearing capability, the worktable is able to directly machine heavy workpieces weighing up to 40,000 kilograms, enabling efficient and stable machining of gigantic and complicated parts.

Your reliable helper in achieving high-precision, multi-angle, and high-load machining, this workbench will enhance production efficiency and machining quality.

The Oturn CNC milling and boring machine has high-rigidity rectangular sliding guideways, coated with the surface of PTFE, significantly reducing friction and vibration, improving the precision of machining, and enhancing equipment life.

The X-axis uses high-performance ball bearings combined with a steel composite structure to ensure excellent rigidity and smooth, sensitive dynamic response.

The Y-axis uses hardened rails with a hardness of HRC60±2, coated with PTFE, and a block-type guide structure to effectively reduce friction and ensure long-term high precision.

The Z-axis also employs a steel composite guide rail structure, offering outstanding load-bearing capacity and stability, capable of easily handling heavy-duty machining requirements.

Spindle bearings are sourced from leading manufacturers that offer high-speed operation with excellent rigidity and low-noise operation, yielding precise spindle rotation and extended service life.

These design features equate to smoother machine operation, higher precision, and reduced maintenance frequency and cost.

Choosing Oturn means choosing leading structural design, helping you achieve efficient, precise, and reliable manufacturing production.

Support customization

The Oturn CNC boring and milling machine supports diverse customization options to meet your personalized machining needs. Whether it’s various milling or turning workbenches or optional variable-speed brackets, these features enable you to easily machine threads and complex processes, significantly expanding the machine tool’s machining capabilities.

A wide range of tool magazine options, diverse tooling configurations, and accessory heads enable the machine to adapt to a broader array of machining tasks. You can also equip the machine with specialized accessories such as vertical CNC rotary tables and right-angle milling heads according to production requirements, achieving more efficient and flexible production layouts.

Boring is a common machining operation used to increase and finish holes with high precision. Fixture boring is a unique high-precision method emphasizing very tight dimension tolerances and precise hole placement. It is primarily utilized in machining molds, fixtures, and aerospace parts to meet high precision requirements.

Traditional milling and drilling machines rely primarily on human control with low precision and reliability. CNC machine tools utilize computer control to support automatic movement with higher processing precision, reliability, and efficiency. They can enable complex multi-axis processing with fewer human interactions, taking less time, and lowering error rates.

G-code controls the motion path and cutting path of the machine tool, telling it “where to go” and “how to get there.” M-code controls the auxiliary operation of the machine tool, such as starting and stopping the spindle and turning the coolant off and on. They work together to allow for a continuous and precise machining process.

Our computer numerical control milling and boring machines are suitable for cutting a wide range of materials, such as metals like steel, aluminum, titanium alloys, and cast iron, as well as plastic materials and composite materials. With their flexible versatility, they find widespread application in automotive, aerospace, and heavy machinery-making industries.

Regular maintenance is the most significant factor in sustaining the long-term productivity of machine tools. Our equipment typically gets serviced every 6 to 12 months, depending on utilization. With its robust build and quality components, downtime is kept to a minimum to a very large extent, and our professional support staff is always at hand to provide instant help to facilitate smooth production.
