Why Is There a Variation in the Precision of Holes Machined on the Same CNC Boring and Milling Machine?
When processing similar workpieces on the same horizontal floor boring machine, certain differences may still occur in the aperture, position or surface quality. The reason is not a single factor, but is related to the machine tool structure, machining stroke, spindle status, workpiece clamping, and lubrication and chip removal conditions during the processing process. For large and complex workpieces, when purchasing CNC boring and milling machines, it is especially necessary to judge whether the equipment is suitable for actual processing tasks from these aspects.
The Structure and Rigidity of the 天美直播Tool Are the Foundation.
Boring is a process that requires high processing stability. When the workpiece size is large, the processing depth is increased, or a large cutting amount is required, the stability of the machine tool structure will directly affect the processing process.
The CNC boring and milling machine adopts a floor-standing structure, so that the workpiece can remain fixed, while the processing system moves along the required area, which can reduce the errors caused by repeated lifting and re-aligning of large workpieces. Take DALIAN WAJI's T69 series as an example. It adopts a movable column structure and a modular design. Different models of boring shafts have diameters of 130 - 260 mm, and column travel can reach 4,000 - 10,000 mm. Configuration can be selected according to the workpiece size and processing range.
The Boring Shaft and Stroke Configuration Cannot Be Based on the "Maximum Size" Only.
For the same equipment, if the actual processing position is close to the stroke limit, or the boring shaft extension and processing depth do not match the workpiece structure, processing stability may also be affected.
Therefore, when purchasing, we cannot only compare the "maximum processing range", but also judge whether the boring shaft stroke matches the shaft stroke of the machine tool based on the hole diameter, hole depth, workpiece size and hole position.
Different models of our T69 series have boring shaft strokes of 800 - 1,500 mm and headstock strokes of 2,000 - 5,000 mm. The specific configuration can also be expanded according to customer needs.
Lubrication and Chip Removal Can Also Affect the Continuous Processing Status.
Large workpieces usually take a long time to process. If the lubrication state of moving parts such as guide rails is unstable, or chips and cutting fluid cannot be processed in time, it may affect the continuous operation of the equipment.
DALIAN WAJI's T69 series heavy-duty milling and boring machines are equipped with an automatic lubrication system to provide lubrication for the guide rail through an electric pressure unloading lubrication pump; and a spiral automatic chip removal system to help timely discharge of chips generated during the processing process.
Real Purchasing Judgment Should Go Back to the Artifact.
When a buyer finds that "there are differences in the accuracy of holes processed by the same horizontal floor boring machine," he should not only pay attention to the nominal parameters of the machine tool, but should combine the workpiece drawings, material, hole size, processing depth, processing technology, tool requirements and production conditions to make comprehensive judgment. Whether the machine tool specifications match the actual workpiece is more important than simply selecting a larger model.
This is also the idea used by DALIAN WAJI when configuring CNC boring and milling machines. Our company was established in 2003, jointly invested by Qier 天美直播Tool Group and the former Dalian Wafangdian 天美直播Group, and has inherited the long-term accumulated manufacturing technology and talent base of Wafangdian Heavy 天美直播Tool. Our company currently has a registered capital of 80 million yuan and a modern chemical plant of about 130,000 square meters, and has established a production system that combines R & D, manufacturing and sales.
In terms of specific product configurations, the T69 series does not adopt a single specification, but provides different configurations such as T6913D, T6916D, T6920D and T6926.
Select the Right Floor-Type Boring Mill for Your Application
The actual equipment specifications can also be determined based on the workpiece drawings, materials, processing procedures, size accuracy, aperture, tools, and production conditions.
Contact Dalian Waji for equipment selection and technical support.
The actual equipment specifications can also be determined based on the workpiece drawings, materials, processing procedures, size accuracy, aperture, tools and production conditions. For special processing needs, we also support further discussion of equipment configuration based on drawings or documents.
If your workpiece needs to be processed with porous holes, complex structures or large non-standard parts, providing workpiece drawings and key processing requirements before determining the specifications of the CNC boring and milling machine is more valuable than directly asking "What is the maximum processing size?"
