In the competitive landscape of automotive manufacturing, time-to-market and precision are no longer optional—they’re survival tools. That’s why engineers at Ningbo Kaibo CNC Machinery Co., Ltd. developed the FH1890L Large-Travel Vertical Machining Center, engineered not just to meet but exceed expectations in high-efficiency rough machining of large components like engine blocks, transmission housings, and chassis parts.
The foundation of any reliable machine is its structure. The FH1890L uses a monolithic cast iron bed with internal stress-relief heat treatment—standard practice in premium machines—but Kaibo takes it further by incorporating finite element analysis (FEA)-optimized geometry. This reduces vibration by up to 42% compared to conventional designs, ensuring consistent surface finish even during aggressive cutting.
Combined with linear guide rails rated at H7 tolerance (±0.01 mm over 1 meter), the system maintains positional accuracy under heavy loads—a critical factor when processing oversized aluminum or steel castings where thermal expansion can cause misalignment.
Equipped with a 22 kW spindle motor delivering 320 N·m torque at low RPMs, the FH1890L excels in roughing operations that demand both power and control. For example:
| Parameter | FH1890L | Standard Competitor |
|---|---|---|
| Max Spindle Speed | 8,000 rpm | 6,000 rpm |
| Torque at 500 rpm | 320 N·m | 200 N·m |
These specs translate directly into real-world benefits: faster material removal rates without sacrificing tool life or part quality—especially crucial for high-volume production lines.
Powered by a Mitsubishi M800 controller, the FH1890L delivers exceptional responsiveness and stability. In tests conducted at a German Tier-1 supplier, the machine achieved a 98.7% cycle time consistency across 100 consecutive runs—far above industry average (typically 85–92%). This level of repeatability minimizes scrap and maximizes throughput.
One of the biggest challenges in complex automotive part machining is accessibility. The FH1890L supports multiple attachments:
Together, these features reduce fixture changes from an average of 4 per job down to 1—boosting productivity significantly.
A major Chinese EV manufacturer reported a 25% reduction in machining time for their battery housing components after switching to the FH1890L. Before implementation, they relied on two separate machines—one for roughing, one for finishing. With the FH1890L, they consolidated processes, reduced labor costs by 18%, and improved first-pass yield from 89% to 96%.
That’s not just efficiency—it’s competitive advantage.
