Introduction of Ceramic Knife

Ceramic knife known as "noble knife", as a modern high-tech products, with the advantages of traditional metal knives unmatched; using high-tech nano-zirconia materials, so ceramic knife called "zirconium gem knife", its elegance and luxury evident.


Application of Ceramic Knife


1. The ceramic knife can prevent itself from cautery of serious of acids and bases organic 

    matter,rustiness,changing colors and diffluence of metal ion,so it would be more healthy

    and environmentally-friendly.

2. It`s easy to clean and can keep the primitive colors and original sapor of food. Besides,

    it would not reat with the food that it seldom leads to microorganism breeding.

3. The knife is nonmagnetic completely.And it is made of compactd material so that it is

    with no holes.



Advantage of Ceramic Knife

1.Lasting sharp,Never need to whet knife

2.Food oxidation resistance, retain freshness

3.Non rusty,no chemical reaction when contact with food

4.Healthy and environmental protection

5.Quality life choice

6.Elegant appearance


Packing of Ceramic Knife


1.Flocking plastic in Gift box

2.EVA White box

Q:What are the causes of tool wear and breakage?
Chemical wear refers to tool material and workpiece material chemical reaction caused by adhesive wear, refers to the chip or the processed material and tool cutting tool coating bond will stick together, there are some other tool failure shape, such as heat failure, namely the tool because of the high temperature lead to deformation
Q:Processing about 60 degrees of material, what is good?
The 60 degree is the hardness of the material. With a carbide cutter. Their hardness is 89~93 degrees. At 800~1000 DEG C can undertake cutting.
Q:What is the relative motion between the tool and the blank?
When the standard gear is processed by a rack cutter, the dividing line of the cutter (the line whose tooth thickness is equal to the width of the tooth) is tangent to the dividing circle of the wheel gear and makes a pure rolling.The relative position is determined by the gear shift coefficient; the rack cutter is moved once again when the position is determined. The wheel can rotate at constant speed, the tooth pitch, the modulus and the pressure angle of the tooth number.
Q:Cutting tool materials
Generally speaking, tool steel. High speed steel.Cemented carbideCermetCBN cubic boron nitridePCD diamond
Q:What is the reference system of tool geometry?
The reference system of cutting tool geometric angle can be divided into two categories: static reference system and working reference system.In order to ensure the smooth operation of the cutting process, to obtain a qualified processing surface, the cutting part of the tool must have a reasonable geometric shape. Tool angle is an important parameter for determining the geometry of the cutting tool.
Q:What are the causes of tool wear in cutting?
Phase change wear. Because of the increase of cutting temperature, the metallographic structure will change, and the hardness of the cutting tool will decrease, which will lead to wear.
Q:How to select the tool according to the material
(1) hardness and wear resistance. The hardness of the cutting tool material must be higher than the hardness of the workpiece material, generally require more than 60HRC. The higher the hardness of the tool material, the better the wear resistance.(2) strength and toughness. The cutting tool material should have high strength and toughness, in order to withstand the cutting force, impact and vibration, to prevent brittle fracture and chipping.(3) heat resistance. The heat resistance of the cutting tool material is good, can withstand the high cutting temperature, has the good oxidation resistance ability.(4) process performance and economy. The material of the cutting tool should have good performance of forging, heat treatment, welding, grinding and so on.
Q:Performance difference between high carbon steel and medium carbon steel
Carbon steel finished steel, carbon containing higher hardness increases relatively more brittle, in the production of long knife, the hardness is not the only indicator, so we should consider various factors. The pattern is composed of steel with different carbon content of carbon steel (or different steel grades, but rare, is not easy to play) and co forging, but the shape of pattern steel on the market is far greater than the significance of practical significance, good-looking, but the performance is not necessarily improve.
Q:How to calculate the machining time
Machining distance mm divided by feed speed mm/min multiplied by 60S is the processing time
Q:Turning steel pipe, what is good?
The following two kinds of cutting tools can be used for cutting steel pipe:1 if the hardness is low, so it is sticking to the knife on the lower, available hard alloy cutter "," turning speed is slightly higher, the appropriate amount of feed, the additional coolant side.2 if the hardness of the steel pipe is high or the knife is high, it is recommended to use the diamond cutter". High cutting speed, feed rate, side car additional coolant.
