Automotive – Turbo Impeller Shaft
The turbo impeller shaft is a component that transmits the rotational motion of the turbine wheel. Since it is used in high-speed ranges exceeding 200,000 revolutions per minute, stringent quality control is required for both machining accuracy and tolerances.
In mass production machining, chip control of alloy steel is a crucial factor for maintaining stable machining accuracy and automation. As production volume increases, the need for improvement, stability, and efficiency becomes even more critical.
Tungaloy optimizes customers’ production efficiency by leveraging cutting-edge technology in cutting tool edge geometries and coating materials, enhancing productivity and tool life.

Benefits
- Triple nano technology coating optimized for drilling ensures processing stability and tool life, and maintains productivity in hole drilling.
- Achieves processing efficiency and chip disposal equivalent to solid drills.
- Reduces setup time and tool change time, and eliminates the hassle of tool management, achieving non-surface cost cutting.
DMP head
- Drill head with a tip angle of 140° that can handle any hole drilling.
- Sharp cutting edge treatment for low resistance and long life.
Process 2: Center hole machining
Benefits
- The highly rigid collet-integrated holder allows for optimal tool projection, greatly improving vibration resistance and contributing to the stabilization of mass production.
- We also propose optimal machining solutions, including special solutions, for overall shapes in process integration.
- Reducing setup time and tool change time, and eliminating the hassle of tool management, realizing sub-surface cost reductions.
VDP head
- TungMeister shanks allow center hole drilling from as small as ø1 mm.
- B-type center drills are also newly available.
Process 3: Rough external plunge turning
Benefits
- By using a two-blade tool, efficient cutting is achieved with a large cutting depth.
- By processing while leaving the core, the tool is stable, minimizing minute vibrations and displacements, providing high processing accuracy.
- Two-blade tools have a large cutting area and the workpiece is uniform. This reduces the burden on the tool and achieves a long tool life.
- Our unique coating toughening technology suppresses the progression of cracks that occur during processing, realizing stable processing.
- High wear resistance and chipping resistance ensure a stable long life.
Process 4: Finish external threading
Benefits
- Excellent accessibility to the tailstock.
- The rake angle is reduced when the holder is set, enabling high-precision thread cutting with low resistance.
- The unique pocket shape and three-point clamping system improve the precision of the cutting edge position and the clamp rigidity, increasing the reliability of processing.
- Tool settings with internal lubrication enable high-speed, stable, and highly efficient processing.
TCT18
