Cutting Tool Applications Chapter 12: Milling Cutters and Operations. Lead angles larger than 45 degrees are usually considered special. Milling cutters with large lead angles also have greater heat dissipating capacity. However, if more of the tool can be employed in the cut, as in the case of larger lead
Lead oxide may leak or spill during drive fitting and transfer operations. Lead exposure may occur while collecting and testing oxide samples. Operators may be exposed to lead oxide while cleaning the oxide production line. Exposure may be due to vehicular traffic in adjacent roadways stirring up oxide. Possible Engineering Controls. Use local exhaust ventilation: Install a hood enclosure for the lead melting pot.
In positive/negative milling, some of the advantages of both positive and negative milling are available. Lead angle The lead angle is the angle between the insert and the axis of the cutter. Several factors must be considered to determine which lead angle is best for a specific operation. Basic milling operations Before any milling
