In the automotive parts manufacturing industry, the demand for high - efficiency and high - precision processing of large parts has been increasing. This article will conduct an in - depth analysis of the FH1890L large - stroke heavy vertical machining center newly launched by Ningbo Kaibo CNC Machinery Co., Ltd., focusing on its application advantages and technical features in the rough machining of large automotive parts.
The rigid structure of a machining center is the foundation for ensuring stable and high - quality processing. The FH1890L adopts a box - type structure design, which significantly enhances the overall rigidity of the machine tool. According to experimental data, compared with traditional machine tools, the vibration amplitude during the cutting process of the FH1890L is reduced by about 30%, which effectively improves the surface finish of the workpiece. For example, in the rough machining of engine cylinder blocks, the rigid structure allows the machine tool to withstand greater cutting forces, reducing the occurrence of tool breakage and improving the processing efficiency. In actual production, the processing time for a single engine cylinder block can be shortened by about 20%.
The power system of the FH1890L is equipped with a high - power spindle motor. The spindle speed can reach up to 6000 rpm, and the maximum torque can reach 500 Nm. This high - power output enables the machine tool to perform high - speed and high - torque cutting during the rough machining process. In the processing of large automotive parts such as transmission cases, the high - power spindle can quickly remove a large amount of material, and the material removal rate can reach 500 cm³/min, which is much higher than the industry average of about 350 cm³/min. Moreover, the power system also has a high - precision speed control function, which can ensure stable cutting under different loads, thereby improving the processing accuracy.
The FH1890L is equipped with a Mitsubishi controller, which is known for its high stability and high - speed processing capabilities. The controller can achieve real - time monitoring and adjustment of the machine tool's operating status. For example, during the cutting process, if the cutting force changes, the controller can automatically adjust the spindle speed and feed rate to ensure stable processing. According to statistics, the failure rate of the machine tool equipped with the Mitsubishi controller is reduced by about 15% compared with other controllers, which effectively reduces the downtime of the production line and improves the overall production efficiency.
Proper machining process parameters are crucial for improving processing efficiency and quality. For the FH1890L, through a large number of experiments and production practices, a set of optimized machining process parameters has been developed. For example, in the rough machining of large automotive parts, by adjusting the cutting speed, feed rate, and cutting depth, the processing efficiency can be increased by about 18%. The following table shows some recommended machining process parameters:
| Workpiece Material | Cutting Speed (m/min) | Feed Rate (mm/r) | Cutting Depth (mm) |
|---|---|---|---|
| Cast Iron | 200 - 300 | 0.2 - 0.5 | 3 - 5 |
| Aluminum Alloy | 300 - 500 | 0.3 - 0.6 | 5 - 8 |
The FH1890L is equipped with a variety of multifunctional accessories such as right - angle heads and universal heads. These accessories can effectively solve the problem of processing complex workpieces. For example, the right - angle head can perform side milling and drilling operations on workpieces, which is very useful in the processing of automotive parts with complex structures. The universal head can rotate at multiple angles, enabling the machine tool to process workpieces from different directions, greatly expanding the processing range of the machine tool. In the production of some special - shaped automotive parts, the use of these multifunctional accessories can reduce the number of times of workpiece clamping by about 30%, thereby improving the processing accuracy and efficiency.
A well - known automotive parts manufacturing company introduced the FH1890L heavy vertical machining center. Before using this machine tool, the company's production line had problems such as low processing efficiency and high scrap rate in the rough machining of large parts. After using the FH1890L, the processing efficiency of large parts increased by 30%, and the scrap rate decreased from 5% to 2%. This not only improved the company's production capacity but also reduced production costs and enhanced market competitiveness.
In conclusion, the FH1890L large - stroke heavy vertical machining center has significant advantages in the rough machining of large automotive parts. Its rigid structure, powerful power system, stable controller, optimized process parameters, and multifunctional accessories all contribute to improving processing efficiency and quality. If you are looking for a high - performance machining center for automotive parts processing, the FH1890L is definitely a great choice.
