UNI Series of Deep Hole Drilling Machines

Description

UNISIG has added the new versatile, high-precision UNI-50BTA to its UNI series of deep hole drilling machines. The machine extends production range by enabling operators to rapidly change from BTA to gundrill deep hole drilling tooling. This allows drilling holes with diameters as small as 0.31" (8 mm) and as large as 2.56" (65 mm), at depth-to-diameter hole ratios of 100:1 or greater. The UNI-50BTA makes it possible to drill with either tooling method within the diameter range in the same part without secondary operations.


The UNI-50BTA features a revolutionary pressure head design that enables operators to make the tool change without dismantling the machine, reducing the time for changeover from several hours down to as low as 10 minutes. The machine further enhances productivity by combining elements from UNISIG’s other successful product lines into one high-value machine. This provides flexibility in demanding high-production or high-precision applications such as aerospace landing gear actuators, helicopter main shafts and diesel engine and transmission components.
