overview
1. Look at the processing process: if the processing process, continuous regular sparks, indicating that the tool has been worn, according to the average life of the tool
Change knives in time.
2. Look at the color of the iron filings: the color of the iron filings changes, indicating that the processing temperature has changed, and this time the tool has begun to wear.
3 Look at the shape of the iron filings: zigzag on both sides of the iron, abnormal curling of the iron filings, and the iron filings become finer, which are all tools
The judgment basis of damage.
4. Look at the surface brightness change of the workpiece: the brightness continuously reduces the tool has been worn.
5 Processing vibration sound changes: tool wear will cut the resistance is too large, pay attention to avoid "knife", resulting in workpiece scrap
6. Observe the change of machine load data: If there is a significant incremental change, it indicates that the tool has been worn.
7. Observe the burr change on the edge of the workpiece: when the tool is cut out, the workpiece has a serious burr and the phase roughness decreases.
8. Observe the size change of the workpiece: obvious phenomena such as the size change of the workpiece are also the criteria for tool wear.
9. Tool life table (based on the number of processed workpieces): some high-end equipment manufacturing or single product mass production enterprises use it to guide production, this method is suitable for processing expensive aerospace, steam turbines, automotive key components such as engines and other production enterprises.

Cutting speed
Characteristics of polycrystalline cubic boron nitride PCBN:
The best tool material known for both high hardness and high temperature resistance.
It goes through high temperature and high pressure twice in the manufacturing process
1. Under high temperature and pressure, hexagonal boron nitride (HBN) is converted into cubic boron nitride (CBN).
2. Then cubic boron nitride micro-nanocrystal powder and binder were synthesized into polycrystalline cubic boron nitride (PCBN) under high temperature and pressure.
PCBN is chemically inert and will not react with ferrous metals at high temperatures
1. Used for processing cast iron
2. Used for processing high hardness, high wear resistant alloy cast iron and casting high speed steel
3. Used for processing hardened steel
4. Used for processing difficult materials, such as: superalloy, tungsten carbide, etc.
Processing materials: For ferrous metals with extremely stable chemical properties, hardened steel (45-60HRC), bearing steel (60-62HRC) high-speed steel (>62HRC) tool steel (57-60HRC), chilled cast iron out and fine turning, can be realized to replace grinding, greatly improve processing efficiency.
Processing life: fracture toughness, high hardness and toughness, good wear resistance and strong collapse resistance.

Our advantage:

• 1. 10 years experience in carbide roll and cutting tool manufacturing
• 2. From row material to tool produdtion.
• 3. World top level prodution equipment and rich experience team

ATTACTION:

• 1.Make sure work piece and machine are stable and use a precision holder.
• 2.Please adjust the speed,feed and cutting depth according to actual cutting conditions.
• 3.The milling conditions are for an end mill where the tool overhang length is less than 4*D(mill diameter). When the tool overhang length is longer, please adjust the speed,feed and cutting depth.
