(HRC55°/56°/58°/60°/62°/65°) Ball Nose End Mill

1. Ball-end milling cutters are tools with ball-end-like blades that are installed on milling machines and used for milling various curved surfaces and arc grooves. Ball end milling cutter is also called R cutter
2. Made of carbide/tungsten steel, which is sharper and wear-resistant.
3. Coating: Importedtarget DLC colorful coating
4. Support customization
5. HRC: 55°/56°/58°/60°/62°/65°
6.Flute:2
7. Applicable: copper, aluminum, aluminum alloy, aviation aluminum, magnesium alloy, zinc alloy, etc.
8. Applicable machine tools: CNC machining centers, engraving machines, precision engraving machines and other high-speed machines
9. Main features: The sharp-angled positive rake angle blade is finely ground and sharp. The 2Flute geometric cutting design is more stable during cutting. It adopts a new spiral groove design and a large-capacity eyebrow row space to make cutting smoother and non-stick, achieving high efficiency. Processing, high workpiece precision and good gloss
10. Chinese source manufacturer, cheap price

FQA:
1. Rapid wear of the back rake face
① Under conditions of equal metal removal rate, reduce the cutting speed or increase the feed rate;
② Check the coolant flow rate.

2. Micro-chipping on the Flute
① Reduce the feed rate;
② Use climbing (up) milling;
③ Check the machine tool's backlash and stability;
④ Inspect the tool holding condition;
⑤ Reduce the tool overhang length.

3. Flute chipping
Under conditions of equal metal removal rate, reduce the cutting speed;
Decrease the depth of cut.

4. Poor surface quality
① Increase the helix angle of the tool;
② Increase the number of flutes on the tool;
③ Reduce the feed rate;
④ Decrease the depth of cut;
⑤ Use climbing (up) milling instead of conventional milling;
⑥ Prevent the formation of built-up edge.

5. Vibration and noise
① Adjust the cutting speed (to avoid machine tool resonance);
② Use climbing (up) milling instead of conventional milling;
③ Check the tool clamping condition.

6. Chip clogging
① Choose a tool with fewer flutes;
② Check the coolant flow rate;
③ Direct the coolant onto the cutting edge;
④ Reduce the feed rate.

Reminders:
1. Reducing the tool overhang length by 20% can result in a 50% reduction in tool deflection.
2. When the tool cuts to the corner of the workpiece, the contact arc between the tool and the workpiece increases rapidly, leading to greater cutting forces, more deformation, and higher temperatures at the corner, which can reduce tool life. Therefore, when machining the corners of cavities, it is advisable to slow down.
