The B4035 boring head features an optoelectronic adjustment measuring system and digital display with 0.0001" accuracy in the diameter range of 0.118" to 4.882" (3 to 124 mm). Maintenance-free automatic balance compensation and flexible screw fit connections make this tool suitable for virtually all spindle adaptations, the company says.

The tool’s modular design offers a large diameter range for precision digital boring. The basic head can hold multiple tools, like solid carbide boring bars that cover the working range from 0.079" to 0.394" (2 to 10 mm) and various indexable insert boring bars for ranges from 0.394" to 2.677" (10 to 68 mm). For larger diameters of 2.677" to 4.882" (68 to 124 mm), there are two lightweight bridges made from aluminum. The diameter range above 0.394" (10 mm) needs only two sizes of three-edge ANSI W-type indexable inserts.

The inner coolant supply throughout the tool is consistent both with boring bars and bridges, and the coolant channels are designed to follow MQL technology requirements. According to the company, the backlash-free adjustment and digital display (registering to 0.0001") are extremely accurate, and setup errors are virtually ruled out. In addition, The precision balance allows speeds to 16,000 rpm. The combination of balance, precision and operation safety are intended to ensure quality.
