Sumitomo WRX33000R125-300 Shell Milling Cutter
The Sumitomo WRX33000R125-300 Indexable Shell Shoulder Milling Cutter Body is a CNC milling tool for shoulder and face milling operations. It is identified by the WRX33000R125-300 reference. The cutter body is designed to hold replaceable carbide inserts. It is used in machining centers, milling machines and flexible production lines. The tool supports stable cutting, efficient chip evacuation and good surface finish.
Indexable Milling Cutter Design
An indexable cutter uses replaceable inserts instead of a solid cutting edge. When an edge wears, the insert can be indexed or replaced. This reduces tool change time and maintains consistent cutting geometry. The cutter body is made from high strength steel and is designed for rigidity. Insert pockets are machined to precise tolerances. Clamping screws hold the inserts securely during cutting.
Shoulder Milling Function
Shoulder milling produces a vertical wall and a flat floor in one operation. The WRX33000R125-300 is designed for square shoulder and face milling. It can be used for roughing and semi finishing. The cutter geometry affects cutting force, chip flow and wall accuracy. Correct insert selection and cutting parameters help achieve dimensional accuracy and surface quality.
Applications
Typical applications include mold making, automotive parts, hydraulic components, pump bodies, valve blocks and general engineering. The cutter can machine steel, stainless steel, cast iron and other materials when suitable inserts are used. It is suitable for both small batch and production milling. The tool can be used on horizontal and vertical machining centers.
Installation and Setup
The cutter body should be mounted on a suitable arbor or spindle interface. The mounting surface should be clean and free from burrs. Runout should be checked after mounting. Inserts should be seated correctly and screws tightened to the recommended torque. Coolant should be directed to the cutting zone. After setup, a test cut should be made to verify dimensions and surface finish.
Cutting Parameters
Cutting speed, feed per tooth, axial depth and radial depth depend on the workpiece material, insert grade and machine rigidity. Manufacturers provide starting recommendations. Users should adjust parameters based on chip formation, noise, vibration and tool wear. Excessive speed can cause rapid insert wear. Too low a feed can cause rubbing and work hardening.
Maintenance
Regular inspection includes checking insert edges, pocket condition and clamping screws. Worn inserts should be indexed or replaced. Damaged screws should be replaced. The cutter body should be cleaned before storage. Rust and impact damage should be avoided. Proper handling helps maintain cutter accuracy and extend body life.
Conclusion
The Sumitomo WRX33000R125-300 Indexable Shell Shoulder Milling Cutter Body is a practical tool for shoulder and face milling. It supports replaceable inserts, stable cutting and efficient chip removal. Correct setup, parameters and maintenance help ensure reliable machining results.
