The Junker CNC grinding model BUAJ 30 is a high-precision machine tool designed for external machining of mechanical components. Produced in 1995, this machine represents an excellent combination of robustness, precision and automation. It is equipped with a Fanuc 0-GC command and control system, known for its reliability and versatility, making it an ideal choice for machine shops that require precision in the grinding of cylindrical components.
Grinding Spindle: The grinding chuck is designed to support large grinding wheels, up to 400mm in diameter. It is powered by a powerful motor and regulated via the CNC system, ensuring high working precision.
Work Table: The table has a surface area of 1380 x 160 mm, offering a large working area for grinding large workpieces. The movement of the table is controlled by the CNC system, allowing precise and repeatable positioning of the piece.
Control System: The Fanuc 0-GC is a highly reliable CNC control system, with user-friendly interface that allows you to program complex grinding operations with high precision.
Cooling System: The machine is equipped with a recirculating water cooling system to prevent overheating during processing, thus maintaining the dimensional stability of the piece and prolonging the useful life of the abrasive wheels.
Precision: The Junker BUAJ 30 CNC grinding is designed to guarantee high precision thanks to the Fanuc CNC system and the linear guides on which the axes move. It can machine cylindrical parts with tight tolerances, ideal for high-precision components.
Rigidity and Stability: The cast iron structure of the machine ensures high rigidity, minimizing vibrations during operation and ensuring an excellent surface finish.
Versatility: Capable of processing a wide range of materials, including hardened steels, cast iron, and light alloys, thanks to fine adjustment of the rotation speed of the grinding wheel and adaptation of the grinding process via CNC control.
The machine is ideal for grinding:
Cleaning and Lubrication: It is essential to keep the guides clean and regularly lubricate the ball screws to ensure smooth and precise movements of the axes.
Checking the Wheels: The wheels must be checked regularly to avoid imbalances that could compromise the quality of the grinding. It is also advisable to dress the grinding wheel periodically.
Cooling System: Check the level and quality of the coolant, replacing it according to the manufacturer's instructions to prevent overheating and premature wear of the grinding wheels.
