Adjust the speed, feed, and depth of cut in according to the operating conditions, including the machining shape, machine and, holder rigidity, and workholding force. 2. If the speed and feed rates cannot be increased due to equipment capability, operate by reducing the speed and feed rates at the same ratio. 3. High cutting speeds and feed rates can cause wear and/or reduce machining precision. Therefore, please reduce the feed as...

PHX Deep Feeder Bull Nose Series • In addition to the negative shape of the conventional PHX-CRT high feeder bull nose, it achieves the thermolysis effect. The superior bull nose performs exceptionally well when making deep cuts that are ordinarily susceptible to chattering or when working in materials that are difficult to machine. • The precision of the PHX-CRT high feeder bull nose is ± 0.01 mm, and the deep feeder bull nose series is ± 0.03 mm. • Use the deep feeder bull nose series or the PHX-CRT high feeder bull nose to suit your radius precision requirements. The Thermolysis Effects...

Overhang conversion table of the PHX-PC (Pencil Neck) Series The following table is to calculate the new overhang length, since rigidity has been improved with the use of Pencil Neck. Please use below as a reference for your cutting condition. Step 1. Overhang Length : Mill Diameter = L/D Step 2. Overhang Length x Percentage = Converted overhang length for straight shank Ex.) PHX-PC-DBT R3 × 2˚ × 62.3, milling with an overhang of 65mm Step 1.
