How Does Double Column Vertical Lathe Improve the Efficiency of Processing Large Workpieces?
During the processing of large and heavy workpieces, processing efficiency is not just determined by the cutting speed. The rigidity of the machine tool, the load-bearing capacity of the workpiece, the cutting resistance, the processing range and the motion stability will all affect whether the heavy turning process can be carried out stably. The double column vertical lathe provides a stable structural foundation for heavy cutting of large workpieces through a double column structure and a large workbench design.
Why Does Machine Tool Structure Affect Processing Efficiency?
Large workpieces usually generate large cutting forces during the turning process, so the machine tool needs to maintain stable tool movement and workpiece positioning. If the structural rigidity of the machine tool is insufficient, vibration or deformation may affect the processing process and limit the processing conditions.
The double column vertical lathe uses two columns to support the beam to form a more stable machine tool structure. DALIAN WAJI CNC MACHINE CO. LTD's high-precision double column vertical lathe has been structurally designed for vibration and deformation that may occur during heavy processing. At present, the maximum turning diameter of this series of products covers 2500 mm to 8000 mm, and the maximum workpiece weight in different configurations can reach up to 125 tons. These highlight the equipment's ability to process large and heavy-duty rotating workpieces.
As a lathe manufacturer that has served more than 40 countries, we recommend that buyers should not only focus on a certain cutting parameter when evaluating large vertical lathes, but also need to comprehensively consider the machine tool structure and actual processing load.
1. Stable Heavy Cutting Capabilities Help Improve Processing Efficiency.
Large workpieces usually require processing operations such as rough turning that remove large material. In this process, the machine tool needs to withstand a large cutting load while maintaining stable tool movement. DALIAN WAJI's high-precision double column vertical lathe has a tool holder cross-section of up to 70×70 mm and a maximum cutting force of up to 80 kN.
The processing efficiency of large workpieces cannot be judged simply by the power of the main motor or the cutting speed. Whether the machine tool can remain stable under the actual cutting load is equally important. During the selection process, purchasers are advised to pay attention to whether cutting force, machine tool structure, workbench performance and tool movement can be matched.
2. Large Workpieces Require Sufficient Workbench Carrying Capacity.
Loading and supporting workpieces are important links in the processing process. Vertical turning uses a horizontal workbench to support the workpiece, making it particularly suitable for machining large diameter rotating parts.
DALIAN WAJI's double column vertical lathe includes products in different specifications. Among them, the maximum turning diameter of the medium series covers φ2500-φ4000 mm, and the heavy series covers φ5000-φ8000 mm; depending on different models, the maximum workpiece weight ranges from 12 tons to 125 tons.
This specification range means that buyers can choose equipment based on their own large workpiece processing needs, rather than using the largest machine tools for all projects.
3. Guide Rail Performance Is Also Related to Motion Stability.
Processing efficiency is not only related to cutting ability, but also related to whether the moving parts of the machine tool can operate stably.
For large vertical lathes with a maximum turning diameter exceeding φ5000 mm, DALIAN WAJI uses hydrostatic guides as a standard configuration. Its working principle is to form an oil film between the moving parts and the guide rail to achieve higher carrying capacity and reduce direct metal contact between moving parts.
4. Matching Equipment with Processing Tasks Is More Important Than Simply Choosing a "Big Machine".
The larger the size of the machine tool, the higher the processing efficiency. What really matters is whether the equipment capabilities match the actual processing tasks.
DALIAN WAJI's dual-column vertical lathe series has different table speeds, maximum workpiece heights, load carrying capacities and motor configurations. For example, the medium series uses a 55 kW AC main motor; the heavy series uses a 90 kW AC or 132 kW DC motor depending on the specific model.
Therefore, for buyers, when choosing a double column vertical lathe, a more reasonable idea is to determine the required equipment capabilities based on the actual workpiece and processing process, rather than directly selecting the maximum specification.
What Should Buyers Pay Attention to When Evaluating the Processing Efficiency of Double-Column Vertical Lathes?
When comparing different double-column vertical lathes, you can focus on the following aspects:
· Machine rigidity under heavy cutting conditions
· Maximum cutting force
· Worktable load capacity and speed
· Maximum turning diameter and machining height
· Guide rail structure
· Tool holder structure and stroke
· CNC system and automation configuration
DALIAN WAJI's double column vertical lathe supports SIEMENS and FANUC CNC systems, and can optionally have a full closed-loop control system. According to different project needs, semi-enclosed protection, automatic chip removal machines and customized tool systems can also be configured. Buyers can make configuration choices based on actual processing processes and production needs.
Processing efficiency is closely related to the structural stability, load-bearing capacity of the machine tool and the movement stability during the cutting process.
