Model BB7000 Portable Boring Bar Design Features Setup & Operation Components & Accessories Technical Data CLIMAX Portable Machine Tools, Inc.
Features & Options The compact Model BB7000 offers big job boring capability on-site. Modular components allow you to choose exactly what you need for your application. Modular versatility. • Bearing support system consists of three independent mounting fixtures that can be used alone or in different combinations. If space is limited, mount the bearing cartridge directly on the workpiece. Or use the bearing cartridge with the spacer flange and/or the mounting spider.
Operation & Applications Easy setup and operation help you maximize your uptime. There are several ways to set up the Model BB7000, depending on the application and clearances around the work area. Weld standoffs to the work piece around the bore, positioned to match the slots on the mounting spiders. Next, lift the bar into position, set it on wooden V-blocks and position in the bore.
