Button Cutters May Be For You
Button cutters, or copy mills with round inserts, offer a number of advantages - especially in shops with limited-horsepower machine tools. Owing to recent design improvements, round cutters:
- are no longer limited to light-cutting applications
- can handle difficult machining operations, such as circular and helical interpolation, ramping, shoulder milling, slot milling, plunging and ramping, in a variety of materials.
A major advantage of button cutters with round inserts is their high edge strength. The weakest section of a milling insert is the corner that is constantly exposed to interrupted cuts and heat changes, making it more likely to break
Custom Ball Hones Finish First
Ball-style hones are highly specialized abrasive, flexible and low-cost tools utilized in the automotive, aerospace, manufacturing and machining industries for sophisticated surfacing, de-burring and edgeblending. But all honing tools are not created equal. While many share fundamental characteristics, there is a significant quality difference between a generic tool selected from a catalog and a custom-adapted honing tool engineered to meet specialized requirements.
2-Axis Rotary Speeds Up 5-Axis Machining
A 2-axis rotary for complex 5-axis machining eliminates second and third machining operations. When used on a 3-axis VMC, the 2-axis positioning system eliminates the need for sine plates and other expensive fixtures for angular milling. The 2-axis units are a combination of two systems and can be used as a single component for 5-axis machining, or disassembled for separate operating use.

Live Tooling Eliminates Job Labor
This shop was comfortable running job quantities of about 10 pieces to 20 pieces at a time by performing the first and second part operations on a lathe, then transferred the parts to a mill for the remainder of operations. But, when the customer increased job quantities, the shop struggled to keep up and was forced to farm out some of the work at various stages to eight other shops. When the shop acquired a turning center with live tooling options and high pressure coolant, along with the use of carbide cutters, machining operations and part quality improved dramatically and all operations could be done in-house. But the real benefit is how seldom the parts had to be handled.
