Portable Machine Tools > Machining Centre

A simple and inexpensive solution to convert the Hofmann Portable Line Boring Machine into a horizontal or welding positioner. Suited to welding or machining operations such as pivot eyes, linkages, hydraulic cylinders, pump housing, 'O' ring and circlip grooves and many more.

A practical and thoroughly engineered solution, the Hofmann Machining Centre is suitable for any mechanical engineering environment, yet still provides flexibility and portability for on-site machining operations.

• Table area 1500mm x 1200mm
• Maximum between boring bar bearing supports using single table 1150mm
• Modular construction of table suitable to extend by bolting extra tables to the side and rear
• Maximum height table to boring bar centre 1100mm
• T-slots for clamping (22W x 45W x 35H) every 300mm square pattern
• Suitable for line boring 1000mm dia.
• Suitable for facing to 600mm dia.
• Suitable for machining recesses, 'O' ring grooves, circlip grooves and internal screw cutting (extra attachments)
• Suitable for bore reclaiming work by welding up to 1000mm dia.

Setting up procedure

• Adjust movable support column and self-aligning bearing boring bar suppor brackets roughly to suit the job
• Set job by eye in line with boring centre line
• Slip boring bar through self-aligning bearings
• Line up boring bar to suit job. Turn boring bar by hand using fine adjustment to shift self-aligning bearings
• Slip machine mounting bracket over boring bar and clamp
• Slip boring head over boring bar and clamp on spherical seat
• Set tool and machine
• Setting for welding inside diameter is similar

It is as simple as shown. No other horizontal borer does it faster and easier.
