Long Bed CNC Lathe for Sale

What is Long Bed CNC Lathe

Tsinfa’s long bed CNC lathe is specifically designed for extended workpieces, achieving turning, grooving, facing, and drilling. Its bed length is extended into 2- 3 meters or longer on the base of standard lathes. The long bed CNC lathe has significant advantages in machining long shaft components and tubes, offering ample processing space for these components. The long bed provides stable supports for the workpiece, efficiently reducing displacement or deformation issues during the machining process.

Advantages of Long Bed CNC Lathe

Long Bed Advantage

Compared to common CNC lathes, the key advantage of the long bed CNC lathe is length of the bed, which offers the lathe flexible machining ability. The bed length of long bed CNC lathes can reach 3 meters or longer, and is available to process workpieces with different size and length. It allows one piece machining of extremely long workpieces, preventing welding deviation issues caused by segmented processing. The bed length advantage also shortens machining cycles, reducing the production costs.

High Precision

The machining process of long bed CNC lathes is controlled by precise computer systems, such as Siemens, Fanuc, and other high-end CNC systems. Its location precision can reach 0.005mm, compensating for deviation generated in the machining process. The smart control system is automated to correct tiny straightness errors of the bed guideways. Even if machining a long workpiece, it also ensures the axial dimensional accuracy. At the same time, the bed of this lathe is made of casting material, which can resist internal stress of the production process and prevent deformation. If your project has strict demands for tolerance, the long bed CNC lathe is an ideal choice.

High Rigidity

The long bed CNC lathe is produced by high grade steel and iron, matching a guideway with high rigidity. It possessed high vibration resistance and strong torque, reducing vibration levels caused by high speed cutting. Compared to traditional lathes, the long bed design improves 30% rigidity to make the lathe suitable for cutting heavy materials, such as stainless steel and alloy steel. The long bed CNC lathe can also withstand 10 tons and more, and is suitable for cutting requirements of various heavy and high-load components.

Automation

The CNC system of long bed CNC lathes is completely controlled by computers, and is programmable to suit different machining processes to achieve high automation. It can adjust support locations based on the length of workpieces, reducing accuracy issues caused by offset. In addition, the CNC system also monitors the machining process in real time and adjusts temperatures according to the coolant system. When the components are too worn to work, the long bed CNC lathe will down out automatically to protect the safety of operators and equipment.

Cost-Effective

Long bed CNC lathes are equipped with tool changer systems that have many slots to achieve integration of various cutting tools. So the lathe does not need separate tools devices, which can reduce the initial investments. The long bed CNC lathe can complete turn, thread, drill, and groove material for one time, achieving one piece machining workpieces. This function improves the machining efficiency and is suitable for mass production while ensuring the parts consistency. The smart control system of the long bed CNC lathe also decreases the labor input, reducing your entire costs.

Long Bed CNC Lathe Applications

Heavy Machinery

Components of heavy machinery typically have features of long length, heavy weight, and high precision, such as long shafts, lead screws, gear shafts, etc. The long bed CNC lathe is widely used to machine these components due to its stable guideways and precise spindle, decreasing the dimensional errors. It achieves low surface roughness to reduce subsequent polishing and grinding processes.

Automotive and Aerospace

Automotive and aerospace industries generally have strict demands on the precision of components. The material used in the industry is heavy and not easy to cut. The long bed CNC lathe can achieve stable production of heavy materials, ensuring the precision and dimensional consistency of workpieces. Common components produced by the long bed CNC lathe include engine crankshafts, drive shafts, aircraft landing gear, and others.

Energy Industry

The long bed CNC lathe is also used in the energy industry, such as connecting shafts of wind power equipment and drill pipes of oil drilling devices. The long bed CNC lathe can achieve one piece machining, ensuring the entire stability and precision of the components. At the same time, the lathe can work together with an automated loading and unloading system, and is suitable for batch production.

How to Select Long Bed CNC Lathe

When choosing the long bed CNC lathe, you should not only consider the parameters and price, but also make the decision based on actual requirements, production scale, and long term planning. A proper lathe can provide high ROI for your project, while not suitable one may cause certain loss and damage. The following factors for your reference:

• Bed Specifications: The bed specifications is the basic factor that you should consider, it is directly connected with the machining function of lathes. You can determine the bed dimensions according to the maximum length and diameter of workpieces, while also reserving sufficient space to ensure machining safety.
• Spindle: Spindle is the key component to drive the lathe work, affecting stability and precision of the machining process. When selecting the long bed CNC lathe, you need to concentrate on the spindle parameters, including speed range, diameter, and runout accuracy. Heavy or hard materials like steel and iron, require high rotation speed and torque to ensure the cutting power. While soft materials like aluminum alloys typically need high speed to improve the surface finish.
• CNC system: It is better to choose the brand that has high market recognition, such as Fanuc and Siemens. These systems is easy to maintain and possess high stability and compatibility, reducing failures caused by program conversion. The choice of control systems also needs to consider the actual machining requirements and the familiarity of engineers. A familiar control system can reduce the learning and adaptation time, improving production efficiency.
• Lathe Performance: The long bed CNC lathe is generally used to machine large workpieces, having higher demands on performance than common lathes. You can comprehensively consider the actual production and workpieces parameters to make the decision. In general, the lathe produced by casting iron with high strength has good stability and vibration resistance, extending service life of the equipment. The long bed CNC lathe also can be customized on materials and accessories to meet various workpieces demands.
• After-sale Service: The long bed CNC lathe is a long term used equipment, good after-sale service can extend the service life of the equipment. Famous brands or suppliers typically provide reliable support to reduce loss caused by unexpected downtime.
