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.

Notice:

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.

FAQ

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.
