In the field of heavy - duty vertical machining centers, the spindle extension rod plays a crucial and irreplaceable role. Understanding its correct usage and scenario adaptation is the key to enhancing machining efficiency and accuracy. This article, provided by Kaibo CNC, will guide you through the ins and outs of using spindle extension rods in FH1890L large - stroke vertical machining centers.
Spindle extension rods are essential accessories for heavy - duty vertical machining centers. They can effectively expand the working range of the machine tool, enabling it to handle more complex and diverse machining tasks. For example, in the FH1890L large - stroke vertical machining center, the spindle extension rod can significantly increase the depth and length of machining, which is crucial for deep - cavity milling and long - shaft part processing. According to industry statistics, using a spindle extension rod can improve machining efficiency by up to 30% in certain scenarios.
In the automotive manufacturing industry, deep - hole processing of engine blocks and other parts is a common and challenging task. The spindle extension rod can reach deep into the workpiece, ensuring high - precision machining of deep holes. For instance, in the production of a certain engine block, the use of a spindle extension rod reduced the defect rate of deep - hole processing from 5% to less than 1%.
When dealing with large structural parts, such as those used in aerospace and heavy machinery, the spindle extension rod can be used for both rough and finishing operations. It can quickly remove large amounts of material during roughing and ensure high - surface - quality finishing. A customer in the aerospace industry reported that using a spindle extension rod in the FH1890L machine reduced the overall processing time of large structural parts by 25%.
The correct installation of the spindle extension rod is crucial for its performance. First, ensure that the spindle and the extension rod are clean and free of debris. Then, carefully align the extension rod with the spindle and tighten the locking mechanism according to the manufacturer's instructions. A misaligned installation can lead to vibration and reduced machining accuracy.
Proper tool setting is essential for achieving accurate machining. Use a reliable tool - setting device to ensure the correct position of the cutting tool. When it comes to cutting parameters, factors such as cutting speed, feed rate, and depth of cut should be carefully selected based on the material of the workpiece, the length and material of the extension rod. Generally, a lower cutting speed and feed rate are recommended for longer extension rods to maintain stability.
Spindle extension rods come in different lengths and materials, each with its own performance characteristics. Longer extension rods can reach deeper workpieces but may be more prone to vibration. Materials such as high - speed steel and carbide have different hardness and wear - resistance properties. For general - purpose machining, a medium - length high - speed steel extension rod may be a good choice. However, for high - precision and high - speed machining, a carbide extension rod is recommended.
The FH1890L vertical machining center is equipped with a Mitsubishi controller, which offers powerful programming capabilities. By using advanced programming techniques, the operation stability of the spindle extension rod can be significantly improved. For example, by adjusting the acceleration and deceleration parameters in the program, the vibration of the extension rod during high - speed movement can be reduced.
Regular maintenance is essential for the long - term performance of the spindle extension rod. Clean the extension rod after each use to remove chips and coolant. Lubricate the moving parts regularly to reduce wear. A well - maintained extension rod can have a service life of up to 5 years.
Common problems with spindle extension rods include vibration, tool breakage, and inaccurate machining. If vibration occurs, check the installation and cutting parameters. For tool breakage, examine the cutting tool and the extension rod for damage. In case of inaccurate machining, re - check the tool setting and the programming.
