What are the commonly used Zhongshan NC tools for NC machining?
NC milling cutter is a common NC tool. It is also called flat knife.
Commonly used is the white steel knife. First of all, cutting some products with low surface requirements. The price is quite cheap. Relatively simple wear.
Aluminum milling cutter. The main raw material is tungsten steel structure. It is mainly used to cut raw materials for aluminum. The surface finish of the product is relatively smooth.
Coated tungsten steel milling cutter is mainly used to cut steel casting iron. It is relatively heat resistant. Wear resistance. The price is higher.
Drill bit. This is quite common.
Including specification twist drill. It is mainly used to make conventional materials. The punching effect of conventional products. Group drilling, for some special workpiece can play a unique effect. Fixed point drill, center drill. It's primarily used for point center effects.
Chamfering knife. Generally, it can be replaced by a point drill. It is mainly used for product chamfering.
CNC ball end cutter. It is mainly used to process curved surface products. Of course, special use can also be used.
CNC boring cutter. It is used for boring fine holes. Generally, the scale is adjustable. The hole used for machining is relatively high. But compared to reamers. It will not play a hole effect.
Reamer. Reaming effect is the most important. It is generally used for finish hole machining. It can correct the straightness of the hole.
Face milling cutter. Also known as throwing knife. Milling large plane effect. It is also a common tool in machining center.
Round nose knife. Generally, it is a rough effect. It can also be face milling. It is widely used.
Thread milling cutter. Able to mill thread. Be able to program thread washing with programming software.
Tap. It has the effect of product tapping. It is divided into cutting taps. Screw tap. Squeeze tap.
Dovetail cutter. It is named after its shape similar to a swallow tail. It is mainly used to open dovetail groove.
Cutting tools. It is mainly used for product carving effect.
Hob. For machining holes. It can make the surface finish reach mirror level.
T-cutter. It is mainly used for milling T-groove.

What are the causes of chip accretion on NC tools?
The reason is that the chip bottom metal is embedded in the micro uneven peak valley on the front cutter surface due to the large down pressure in the part close to the cutting edge, forming a gap free metal to metal touch, which is called the bonding area. In the bonding zone, there will be a thin layer of metal data accumulated on the rake face at the bottom of the chip. The metal data of this part of the chip is severely deformed and strengthened at the appropriate cutting temperature. With t

What are the wear types of tungsten steel milling cutters?
Abrasive wear machining materials often have some very hard particles, these particles will form grooves on the surface of the tool, which is the grinding loss. All surfaces are worn, especially the rake face. In addition, although the wear of hemp occurs at various cutting speeds, the wear caused by other reasons is not obvious due to the low cutting temperature at low cutting speed, so it is mainly the abrasion of abrasive materials. The lower the tool hardness is, the more serious the grindin
