MFG BK5032/BK5040 CNC Slotting Machine

Servo-Driven Main Drive, HT250 High-Rigidity Castings & KND CNC Control for Precision Keyways

Product Overview
The MFG BK5032/BK5040 is a high-performance CNC slotting machine engineered for machining internal and external keyways, splines, square holes, and complex forming surfaces in various metal materials.

Built to strict industrial precision standards, the core components—including the machine bed, carriage, and worktable—are manufactured from high-temperature aged HT250 premium castings, ensuring maximum geometric stability during long-term operation.

Controlled by the KND CNC system and driven by a high-torque servo motor coupled with a crank mechanism, the BK5032/BK5040 delivers robust cutting force and exceptional verticality accuracy (≤0.02mm). It is a highly efficient slotting solution for automotive manufacturing, mold fabrication, aerospace, and general mechanical industries.

Key Features & Engineering Details

• HT250 Heavy-Duty Cast Architecture: The machine base, column, and worktable are constructed from premium HT250 cast iron. These components undergo rigorous natural and high-temperature artificial aging processes to eliminate internal casting and welding stresses, guaranteeing high rigidity and precision reserves under heavy-load cutting.
• High-Torque Servo Main Drive: The main cutting motion is powered by a high-capacity servo motor driving a crank and connecting rod mechanism through multi-stage deceleration. This design ensures a constant, high-torque output throughout the slotting stroke, making it highly effective for machining tough alloy materials.
• Precision Servo Feeds (X & Y Axis): The X and Y axes are independently controlled by servo motors, offering smooth, stepless speed regulation. Both axes utilize direct-drive, double-nut preloaded ball screws to effectively eliminate transmission backlash and significantly improve positioning and repeatability accuracy.
• KND CNC System & Electronic Handwheel: Equipped with the highly stable KND CNC system, supporting full-screen parameter editing. The machine comes standard with an external electronic handwheel, allowing operators to make safe, micrometer-level manual adjustments during tool setting and trial cuts.
• Strict Verticality Control: Through precision scraping and advanced assembly techniques, the verticality error between the Z-axis ram stroke direction and the Y-axis worktable surface is strictly controlled to ≤0.02mm, fully meeting the requirements for high-precision internal keyway machining.
• Full Enclosure Protection: The machine features a fully enclosed sheet metal guarding design. This effectively contains metal chips and coolant splashes, maintaining a clean shop floor environment and enhancing operator safety.
