A new version of the EWB-UP head features dials with inch graduations. The dials show divisions of 0.00005” on diameter, said to be the finest adjusting resolution on a boring tool currently available. A second dial on the head corresponds to the boring diameter range and is adjusted to correct for the tool imbalance. According to the company, the tool carrier locking system doesn’t influence the tool diameter to ensure the best possible repeatability. This head is part of six boring heads in the series allow users to bore a range of 20 to 100mm (0.787” to 3.94”). The flexibility of the Kaiser KA connection permits a wide range of spindle interface options, the company says. All bore ranges and tool lengths are identical to existing Kaiser tools.
