Precision Boring

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

This modular design offers a large diameter range for precision digital boring. The basic head can hold multiple tools, like solid carbide boring bars, which cover the working range 0.079" to 0.394" (2mm to 10mm), and various indexable insert boring bars for ranges 0.394" to 2.677" (10mm to 68mm). For larger diameters, 2.677" to 4.882" (68mm to 124mm), there are two lightweight bridges made from aluminum. The inner coolant supply throughout the tool is consistent with boring bars and bridges. The MQL technology requirements were considered when designing the coolant channels.

The backlash-free adjustment, with the help of the digital display (registering up to 0.0001") is extremely accurate. Setup errors are virtually ruled out. The combination of balance, precision and operation safety ensure excellent quality.

The B4035 delivers a number of additional features that increase production and lower costs. The diameter range above 0.394" (10mm) has only two indexable insert sizes needed, and these are three-edge ANSI W-type inserts. Additionally, the precision balance allows speeds up to 16,000rpm, reducing machining times.
