A sudden, harsh, annoying "squeaking" sound appears during machining; you want a "mirror finish" effect, but the machining results are out of reach, always showing obvious tool marks; constantly adjusting machining parameters—you want efficiency but can't guarantee tool life, and you want tool life but can only reduce efficiency, making it hard to balance... Are you always struggling with the question: Is there truly a tool that can run fast and last long?!!
To solve the headache of machinists, our Changzhou QT TOOLS designed a 5-flute unequal pitch end mill. This unequal pitch end mill, through precise design, ensures the angle between each cutting edge is no longer equal. This completely disrupts the inherent cutting frequency, preventing the system from forming resonance conditions, thus fundamentally suppressing the generation of chatter. Customers who have used our 5-flute unequal pitch end mill report that this end mill is extremely stable and low-noise during the machining process.
After solving the "resonance" problem, is "aggressive" cutting possible? Can the desired surface finish be achieved?
Compared to a 4-flute end mill, with an equivalent feed per tooth (Fz), 5 flutes mean that the whole feed rate (F) can be enhanced by 25%, significantly enhancing machining efficiency.
Moreover, from 4 flutes to 5 flutes explains that the tool core hardens and the rigidity is enhanced, therefore the tool would not be prone to vibrate and distort during cutting, ensuring stable machining. More cutting edges engage the cutting process at the high speed, providing a residual height on the work surface lower, and by its nature, the surface finish higher.
We have a customer in Slovakia who customized a 5-flute unequal pitch end mill for machining steel parts. Ultimately, ours lasted for 280 minutes! Why could ours machine for such a long time? Because we personalize our products based on the material the customer needs to machine, which better fits the customer's machining requirements.
A good 5-flute unequal pitch end mill is not simply "one more flute"; it is a systemic solution created in response to modern machining pain points. It will help you break through efficiency bottlenecks, enhance product quality, and ultimately reduce overall manufacturing costs.
