How to select right cutting tools according to material characteristics?

Using wrong cutting tools will lead to unstable machining, or even failure to process. Efficiency will be reduced. No good quality can be achieved.The workpiece material and the quantity of material that needs to be removed helps you determine suitable cutting tools.

The material is significant because:

● Part material has an influence on the material you choose for your cutting tools.

● Part material and tool material together have an influence on the spindle speeds and feed rates you choose for your machining operations.

If the material to be processed is relatively hard, we should choose rigid cutting tools. The tip of the cutting tools should be large. Machine must be debugged based on three guidelines: low cutting speed, slow feed rate and less cutting depth.

If the material to be processed is soft (such as aluminium alloy, nylon rod, copper, etc), you can use relevant alloy cutting tools and increase the cutting speed, feed rate and cutting depth. In such cases, if the feeding table runs slowly, there will be slags wrapping around the workpiece, which affects efficiency and quality greatly.

1. Powder preparation

Powders are prepared with great accuracy. When finished selecting 100% virgin materials, it is put into ball mills to grind, blend and mix. Since solvent naphtha does not contain any moisture and won’t increase the oxygen level of the materials, some use it for wet grinding instead of using alcohol.

2. Pressing and Forming

Basically, there are three methods for pressing and forming, including extrusion, isostatic compaction and compression molding. For different products, we apply different methods.

3. Sintering

For sintering process, we use vacuum sintering and pressure sintering methods to make sure the densification of our products and eliminate any potential material weak areas. The higher the density, the better the properties.

4. Finishing

With the latest methods and equipment, including CNC cylindrical grinding, CNC surface grinding, and polishing machines, we are able to polish and grind products to get a competitive finish.

5. Inspection

To control product quality with high-performance inspection equipment and experienced engineers who are dedicated to ensuring the supply of high-quality products.
