Efficient processing of key grooves for the propulsion shaft using NC lathes. Achieving process consolidation and short delivery times.
In the shipbuilding industry, particularly in the manufacturing of propulsion shafts, keyway machining that demands high precision and reliability is essential. The accuracy of the keyway, which affects the performance of the propulsion shaft, is directly linked to the safety of the hull and the efficiency of propulsion, making the optimization of the machining process and quality assurance critical challenges. Our HORN-branded broaching tools enable keyway machining on CNC lathes, eliminating the need for setup changes and reducing effort and time. The excellent chip removal capability provided by internal lubrication achieves high-quality key width accuracy and contributes to the reliability of the propulsion shaft. 【Application Scenarios】 - Keyway machining of propulsion shafts - Efficient keyway machining on CNC lathes - Improvement of setup change operations 【Effects of Implementation】 - Reduction of cycle time through process consolidation (Example: 50 minutes → 20 minutes) - Achievement of high-precision key width accuracy - Elimination of the effort and time required for setup changes
