Gear, as an indispensable part for power transmission in mechanical equipment, has been widely used in modern industrial equipment such as metal cutting machine tools, aviation, power system, metallurgical machinery, agricultural machinery and transport machinery.

In recent years, the research and development of gear NC tools at home and abroad have kept pace with the development of NC efficient machine tools and made great progress. These advances mainly depend on the following aspects: more advanced design technology, more advanced NC special processing technology and precision detection technology, better performance NC tool materials, scientific and advanced surface coating technology, and high-speed steel. The heat treatment technology of gear cutter is also the key.

What is the gear processing technology? Let's first appreciate the whole process of gear processing, very detailed! No regrets!

The whole process of gear processing!

1, product introduction

Lynx Series: Lynx 235/235M

hot-selling models widely recognized in the global market have sales records of more than 17,000 units.

From high-precision processing to mass production of automotive parts industry, to meet the diverse production needs of different customers.

with the increasingly fierce market competition, the old mode of production is no longer suitable for production needs. Customers urgently need high-performance full-function CNC machine tools to replace them. Their requirements for new machine tools are as follows:

1. Easy to operate. Operators can set their posts independently after simple training.

2. Machine tool processing stability is high

3. Machine tools are easy to maintain.

4. Machine Tools Easy to Install Automation Auxiliary Equipment

5. Machine tool protection facilities are safe and reliable. Considering the compact structure, stable processing accuracy, sufficient rigidity and high cost performance of Doushan machine tool, the user finally selected the Doushan machine tool lynx system equipment, and achieved the goal of high precision gear processing and cost reduction and efficiency.

In recent years, the development trend and characteristics of gear cutting tools are mainly manifested in the following aspects.

1. Environmental protection and dry cutting

Environmental protection dry cutting has been applied in gear processing. Compared with traditional wet cutting method, dry cutting method does not need coolant. It is not only environmentally friendly but also reduces the cost of hobbing. Dry cutting method can also adopt higher cutting speed and improve processing efficiency. According to the processing requirements of dry-cutting machine tools, the main tool manufacturers have developed environmentally friendly dry-cutting hobs. The environmentally friendly dry-cutting hobs are divided into integral carbide hobs, carbide indexable hobs and powder metallurgy high-speed steel hobs according to their materials.

2. Cemented Carbide of Gear Cutting Tools

In the traditional sense, gear tool materials are generally high-speed steel (high-performance powder metallurgy high-speed steel has also been widely used). With the development of cemented carbide materials and the progress of processing technology, the proportion of cemented carbide tools has been increasing, which has reached more than 70% in developed countries in Europe. In recent years, various tool manufacturers at home and abroad, such as Gleason, Kennametal, Fette, Ingersoll, Sandvik Coroman, etc. T has developed various carbide indexable gear cutting tools, which greatly improves gear processing efficiency and tool life. The indexable carbide gear hob has 1 or 2 heads, and the blade can be indexated twice or four times. Its modulus range is m5.5-m40. Compared with the high-speed steel hob, the cutting speed of this kind of hob is 100-150 m/min higher (the cutting speed of the same kind of high-speed steel insert hob is only 30 m/min), and the cutting efficiency is increased by 1-3 times. In addition to large modulus indexable alloy hobs, Sandvik Coromant has also developed clamp-type carbide hobs with m5-m8. The difference is that each tooth of the hob uses a blade with assembly accuracy up to DIN B and novel structure.

Advantage:

1. Very high accuracy. Both the body and blade have super high accuracy, which can guarantee at least DIN8 or ANSI5 (equivalent to GB 7).

2. The blade has four cutting edges and the tool body has standard stock, which is the most economical and efficient solution.

3. The splines with different tooth shapes can be machined with the same cutter body and different blades.

4. Because it can be designed as a small diameter, it can approach the shoulder to the greatest extent in milling.
