4 Flutes Carbide Ball Nose End Mill HRC45 Cnc Dia4 4mm Tungsten
Steel Milling Cutter
Characteristic:
- High quality tungsten steel base metal
- Process technology of imported grinding machine
- Double edge belt design for smooth chip removal
- Wear resistant and durable, reduce burrs
- Chamfer design of round handle
Description:
- The new fine grain tungsten steel matrix material has high wear
resistance and strength, and is especially suitable for general
carbide ball nose end mill for high hardness and high-speed cutting
applications; The WALTER machine imported from Germany is used for
processing, with a handle diameter tolerance of 0/± 0.005. The
international standard straight handle can effectively suppress
chatter during processing, which is the basis of excellent quality;
Full grinding edge, the tool surface presents a mirror effect,
improving the surface finish; Refine spiral groove, optimize spiral
groove design, smooth chip removal without sticking the cutter; The
bottom chamfer design is easier to operate during clamping, and the
clamping is more smooth.

- Minimize the use of tool tips to process workpieces: at the
position of the ball head tool tip, the processing linear speed is
0 during actual processing, that is, the tool is not actually
cutting, but grinding. In actual processing, the coolant can not be
added to the cutting area at all, which further leads to greater
cutting heat ratio and reduced tool life.
- For straight wall processing, use contour contour processing
method: try to reduce the phenomenon of ball end cutter processing
downward along the straight wall. Relatively speaking, it is a very
good method to process upward along the straight wall, but it is
difficult to separate them in actual processing. Let's compare the
differences between the two.
- Machining straight wall with contour can reduce downward machining.
If you can use "cutting from bottom to top", this phenomenon can be
avoided. When using "cutting from bottom to top", first consider
whether the cutting capacity of the cutter is too large. If there
are relatively large residues left at the root of the curved
surface after machining above, the cutting capacity of the cutter
may be too large. This will not protect the tool but destroy it.
- The ball end milling cutter shall pay attention to the processing
of deep grooves: when processing deep grooves, the cutter may sink.
Because the chip holding groove of the ball end milling cutter is
relatively small, it is easy to break the cutter when processing
sticky materials (such as red copper) and the feed speed is fast.
Therefore, pay attention to chip removal when using ball end cutter
for machining.
Applications:
Pre-hardened Steel, stainless steel, Die steel, steel plate,
Heat-resistant steel,pipe, copper and aluminum, cast iron,
Nonferrous Metal, Wood, Plastic,FRP and sO on. General-purpose
operation slotting, rilling, profiling.
Q1. The tool breaks when cutting in or pulling out the workpiece
The feed rate and cutting depth can be reduced, and the cutting
edge length can be shortened to the minimum of the necessary
length.
Q2. Tool breaks during normal machining
Reduce the feed rate and cutting depth.
The tool shall be passivated.
Replace the clamp or spring collet.
The tool with high cutting edge number changes the tool with low
cutting edge number to improve chip removal and prevent chip
blockage.
Replace dry milling with wet milling (using cutting fluid), and use
it with vortex tube gun to reduce tool temperature and avoid tool
overheating.
If the wet milling fluid supply direction is changed from the front
to the oblique rear or transverse top, the coolant flow should be
sufficient.
Q3. The tool breaks when the feed direction changes
(1) Use arc interpolation (NC machine tool), or temporarily stop
(temporarily) feeding.
(2) Reduce (decrease) the feed before and after the direction
change.
(3) Replace the clamp or spring collet.
Q4. Problem: Part of the blade tip breaks
Chamfer the corners with manual grinding.
Change down milling to up milling.
