Seco is one of the world’s largest providers of comprehensive metal cutting solutions for milling, stationary tools, holemaking and tooling systems. For over 80 years, we have been more than just a cutting tool provider. We develop and supply the technologies, processes and supports that manufacturers depend on to maximize productivity and profitability.
Optimized roughing can extend tool life, help generate better workpiece surface finishes, and save time by minimizing secondary processing steps. Despite these advantages, many shops still forgo this productive strategy, either because they don’t know how to implement it or don’t understand how it works. Instead, these shops tend to treat their fast machine tools like race cars and run them as fast as possible, while others stick with outdated speed and feed parameters that fail to produce optimal results.
Just because a machine’s spindle can run at 30,000 RPM doesn’t mean it always should, but many shops run high RPMs and feed rates regardless of workpiece design. When they do, their CNC control slows the machine’s feed rate on difficult part features while RPMs remain unchanged. The combination of high spindle RPMs and slow feed rates makes it virtually impossible to maintain the optimal chip loads necessary for the strategy’s success.
