Custom Cutting Tools for Automotive Manufacturing

Aoshiji® Custom Tool provides drawing-specific custom cutting tools for automotive component machining where standard tools cannot efficiently meet the required geometry, tolerance, surface finish or tool-life target.

Typical applications include engine components, transmission parts, aluminum housings, cast-iron components and other precision-machined automotive parts produced in repeat manufacturing environments.

PCD chamfer end mill for edge deburring and chamfering
HSK PCD multi-face milling cutter for four-side machining
PCD guided reamer with guide pads for high-precision bore finishing
Standard HSS machine reamer Ø8 H7 for precision hole finishing and final bore sizing
Carbide step reamer for multi-step bore finishing in steel, designed for stable step diameters and process robustness
Three-step profiled PCD step reamer for stepped bore finishing with formed transitions in one pass

Typical Automotive Machining Applications

Automotive tooling applications may include:

• Cylinder blocks and cylinder heads
• Engine and transmission housings
• Motor and EV component housings
• Gearbox components
• Precision bores and stepped holes
• Oil and cooling system features
• Grooves, shoulders, radii and formed profiles

Custom Tooling for Production Stability

Automotive production often requires stable dimensions, repeatable surface quality and predictable tool life across large numbers of components.

Aoshiji evaluates the component drawing, workpiece material, machining allowance, tolerance, surface finish, machine interface, coolant condition and existing cutting parameters before developing the tool concept.

Where appropriate, multiple diameters, chamfers, radii, steps or profiles can be combined into one custom cutting tool to reduce tool changes and simplify the machining process.

Relevant Cutting Tools

Typical tooling solutions include PCD reamers, carbide-tipped reamers, custom drills, form milling cutters, counterbores, side and face milling cutters and custom form tools.
