Causes and Countermeasures of NC tool edge collapse
2020-10-12 1089
1) improper selection of blade brand and standard, such as too thin blade thickness or too hard and brittle trademark during rough machining. Countermeasures: increase the blade thickness or install the blade vertically, and select the trademark with high bending strength and resistance. 2) improper selection of several parameters of the tool (such as too large front and rear angle, etc.). Countermeasures: we can start from the following aspects to plan the tool from scratch. ① Reduce the front

What are the causes of chip accretion on NC tools?
2020-10-12 1232
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?
2020-10-12 1185
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

Tungsten steel milling cutter is the common name of cemented carbide milling cutter. It is a universal tool made of cemented carbide data (tungsten titanium alloy). Generally used in CNC machining center, CNC engraving machine. It can also be installed on the general milling machine to process some relatively hard and not messy heat treatment data. Tungsten steel milling cutter is widely used and high-speed machining is used. The hardness of tungsten steel milling cutter is very high, usually in

Difference between NC tool and common tool
2020-10-12 1099
(1) the high-precision manufacturing quality is to process the high-precision parts surface safely and stably. Therefore, more stringent requirements are put forward for the cutting tools (including tool parts) in the aspects of precision, surface roughness, shape and position tolerance, especially for indexable tools. In order to ensure the repeated accuracy of the blade tip (cutting edge) in the scale after the rotation, the tool body, tool groove and positioning are required The dimension, ac

What is the difference between cemented carbide milling cutter and tungsten steel milling cutter
2020-10-12 1118
Carbide milling cutter is also called tungsten steel milling cutter. In the machinery industry, many products with the same time are called differently, which leads to unnecessary trouble, such as carbide milling cutter and tungsten steel milling cutter. Many people mistakenly use the milling cutter made of two kinds of raw materials. In fact, many people are brought into this misunderstanding because of the different names. In fact, tungsten steel milling cutter and carbide milling cutter are a

Different NC tools have different characteristics and use direction
2020-10-12 1152
Milling cutter is a kind of rotary cutter with one or more teeth for milling. Each tooth of the cutter is equivalent to a turning tool, which is fixed on the rotary surface of the saw blade milling cutter. When milling, the cutting edge is longer, and there is no idle stroke, VC is also high, so the productivity is high. There are many kinds of milling cutters, which have different structures and are widely used. According to their uses, they can be divided into three categories: plane milling c

What factors affect the quality of carbide milling cutter?
2020-10-12 1129
Analysis of the key factors of cemented carbide milling cutter quality: (1) hardness and durability cemented carbide milling cutter has unique advantages in both hardness and durability. Tungsten carbide (WC) itself has a high hardness (beyond corundum or alumina), and its hardness rarely decreases with the increase of working temperature. However, it lacks enough endurance, which is essential for cutting tools. In order to use the high hardness of tungsten carbide and improve its resistance, me

What are the forms of NC tool wear?
2020-10-12 1147
1) when cutting plastic data at a higher speed, the part near the cutting force on the rake face will be worn into crescent concavity under the action of chips, so it is also called crescent pit wear. In the initial stage of wear, the tool rake angle increases, which improves the cutting conditions and is conducive to the bending and breaking of chips. However, when the crescent groove is further increased, the cutting edge strength is greatly weakened, which may eventually lead to the breakage
