Product Overview: JUNKER PLATEMAT

The PLATEMAT is a newly developed grinding machine designed for machining the external profile and negative chamfer of indexable cutting inserts in a single clamping operation. It features four interpolating CNC axes enabling precise and reliable grinding operations.

Key Features and Benefits

• Capability to machine various indexable insert geometries: triangular, rectangular, square, rhomboid, hexagonal, and circular.
• Supports multiple grinding profiles including constant radius, constant relief angle, and variable relief angle.
• Significant production time reduction of up to 50%, enhancing mass production efficiency.
• High cutting edge quality surpassing previous standards.
• Extremely short machining times and rapid workpiece changeover for high productivity.
• High precision ensured by high-resolution CNC drives.
• Maximum machine availability supported by 3D simulation software (JUWOP/VG).
• Integrated JUNKER automation system for streamlined operation.

Control and Software

The machine is controlled via the proprietary EJ-OP Operator Panel, a modern CNC control platform with a color monitor and integrated PC. The JUWOP/SG software package facilitates:

• Programming of workpiece profiles.
• Definition of grinding operations.
• Calculation of CNC grinding programs.
• 3D simulation of machining processes (JUWOP/VG) to optimize precision and reduce downtime.
