Allied Machine & Engineering offers the BT-A drill. The tool features T-A replaceable-tip technology suited for BTA deep hole drilling applications. The design uses the company’s T-A drilling system inserts, including GEN2 T-A, to maximize penetration rates and tool life. The product can be used with standard BTA, single-tube designs to flush the spent coolant and chips through the tool. The T-A drill insert is replaceable, which eliminates regrind, the company says. Also, balanced cutting enables increased feed rates.
A set of donated boring bars that can be used in a 1954 boring head will enable volunteer machinists to recreate a pair of binoculars for the USS Pampanito.
The forces involved in the milling process can be quantified, thus allowing mathematical tools to predict and control these forces. Formulas for calculating these forces accurately make it possible to optimize the quality of milling operations.
