Proper operation of the ball cutter grinder makes milling cutters more efficient

Correctly operate the ball cutter grinder to make the milling cutter more efficient

Let's take a look at the advantages of ball knives first:

The edge of the large R angle is stronger than the sharp corner of the end mill, and it is not easy to collapse, that is, the life is more stable than that of the end mill. A larger value can be used for the depth of cut, which improves the machining efficiency and improves the quality of the machined surface.

Preparation before use of ball knife grinder:

1. First determine the material of the milling cutter and the outer diameter of the blade, and select the suitable grinding wheel for replacement.

2. Please confirm the material of the milling cutter before grinding. The HSS (front steel) material is CBN grinding wheel, and the tungsten steel material is SDC grinding wheel.

3. Select a suitable collet for the grinding milling cutter, and insert the collet into the collet seat at 45o.

4. After putting the milling cutter into the collet and the chuck seat, connect it with the fixing chuck nut, and put the chuck fixing seat group into the adjustment bench.

5. Place the chuck set and the milling cutter on the tool setting seat, rotate the milling cutter clockwise, and tighten the chuck set nut.

Ball knife grinder grinding operation steps:

1. Adjust the outer diameter fine-tuning, leaving a margin of 0.1mm (0.1mm for each grinding).

2. Adjust the arc fine-tuning, and adjust the size according to the processing needs.

3. Loosen the angle adjustment block according to the requirements of the tool, and rotate the corresponding angle.

4. Grind the outer arc, rotate the bearing seat, and repair the worn edge.

5. Open the protective cover of the grinding wheel, put the clamp set into the rotating bearing seat, adjust the transverse feed carriage and the self-feed carriage, adjust the required size, grind the groove, and rotate the cross carriage to grind.

6. Put the clamp set into the inclined angle seat hole of the inclined angle column, and grind the back angle.

Note for ball knife grinder:

1. Before starting the machine tool, check whether the voltage and frequency of the motor are consistent with the power supply.

2. Check whether the locking structure of the machine tool is locked, whether there is looseness or poor contact.

3. After the work is completed, the dust on the machine tool should be removed, and the unpainted surface should be coated with oil to prevent rust.
