Our customers are mainly agricultural machinery parts wholesaler, harvester parts dealers, as well as combine machine repair shops.

Q: Which harvesters use combine finger?

Combine finger belongs to the combine cutter bar parts. For example, Kubota 488 588 988 1008 semi feed and full feed harvester, Yanmar AG 7085, etc. Combine finger is the most effective knife guard to protect harvester blades. Various brands, whether Kubota of Japan’s small harvester or John deeper of the United States, all need install combine fingers.

Q: How many kinds of combine finger do you keep?

A: There are hundreds of kinds of combine fingers, and the combine parts of each brand are different. The main difference is that the size and appearance, and the material and production process are basically the same.

Q: Can you customize combine fingers for us?

A: We can provide special combine finger parts OEM services.

We usually keep Kubota harvester parts and Yanmar in stock. If you want special combine finger, please provide drawings or CAD files.

You can also provide the actual combine finger sample, the engineer will mapping and consider combine finer parts to wear and tear factors during the operation, then give you a reasonable plan.

The combine cutter bar parts are more likely to wear and tear due to severe operation in the field. Combine Finger is the most frequently replaced spare part in combine parts.

Therefore, the quality requirements of coombine finger are very high for each customer. Frequent replacement results in slow harvesting speed.

If the finger strength is not enough, the whole cutting unit will not work if it is cracked repeatedly.

In order to reduce the damage of other spare parts in the finger and cutting department, we have a complete scheme for quality control.

Each brand of combine has its own different design, so the requirements of combine finger parts are also different.

Q: How to simply identify the quality of combine finger from the appearance?

A: The quality of combine fingers generally depends on the consistency level of production equipment and products of the combine harvester finger manufacturers, so it is difficult for customers to judge the quality by experience. But you can simply understand the quality of the product according to its appearance somehow.

Whether there are obvious concave and convex defects on the surface of combine fingers.

Whether the grinding of combine finger is smooth, whether there are sharp burrs, if any, are unqualified products.

If the accuracy of combine finger is accurate, the size of the left and right inner cavity of the blade should not be ± 0.01mm.

Whether the antirust paint of combine finger reaches a certain thickness, and there is no bubble on the surface.

Combine fingers collide with each other, and good products generally have a clearer sound.

Q: What is the installation clearance between combine fingers and harvester blades?

A： The distance between harvester blades and combine finger is 0.3-1MM (clearance between blades and cutter ring)

The clearance between feeding auger and the bottom plate is 15-20mm

The clearance between the front end of the reel and the bottom plate is 5-15mm

Cutting drive chain 15-20 mm (minimum distance from the outer circle of conveyor chain rake tooth to the bottom plate at feed inlet driven wheel)

A Brief Introduction of the Combine Finger Production Procedure(2019 )

Combine finger is one of the key harvester parts for the combine harvester. Like all the other combine cutter bar parts, combine fingers are manufactured as per thebelow-mentioned manufacturing processes.

A Brief Introduction of the Combine Finger Production Procedure

1.1 The first steps of combine finger manufacture are casting.

The finger is a standard part of combine parts, and cothda has more than 20 years of experience in metal precision casting.

Combine finger has to go through more than ten processes, such as mold opening, casting, grinding, rust prevention, paint, density test, strength test, and so on. harvester blades cothda

Provide you with 100% high strength cobmine finger and other composite parts castings.

Combine finger is a special part of combine harvester. combine harvester parts cothda

Combine finer needs to have very good toughness and rigidity. During the process of high-speed straw cutting, it can quickly divide the grass and protect the harvester blades.

When there are rocks or obstacles in the land, it required the combine fingers to have high strength and rigidity.

Only in this way can the harvesting work be completed smoothly.

Before casting combine fingers, it is necessary to prepare high-quality iron sand and rare metal ratio in advance. Only in this way，the finished combine parts can be ready for the next step of quenching and grinding, antirust treatment, and painting.

Combine finger is usually made by melt casting and low-pressure casting. Lovol Word Combine Finger

In different harvester finger manufacturers, the combine fingers are usually produced by filling the mold with liquid metal and solidifying it into a casting under the action of low-pressure gas.

The low-pressure casting was initially mainly used for the production of ferroalloy and aluminum alloy castings, and then further expanded to produce iron and steel castings with a high melting point. Many of the harvester parts are made by this method.

Many combine cutter bar parts are cast with high precision, such as gears, driving wheels, and so on. OEM Combine Finger

During the actual use of combine fingers in the farms, combine finger product fracture often occurs, which is due to the quality defects caused by invisible micro bubbles in the combine finger itselt. The main reason for this flaw is that the iron sand selected by some combine finger manfacturers & suppliers is not up to standard, and the boiler temperature control accuracy is not enough, resulting in 15% ~ 30% of the defective combine finger products in the casting process.

The requirement of iron sand is very high in melting and casting. Our combine finger products were made by adopting domestic first-class raw materials and Japanese imported additive dosage. At the same time, the temperature is strictly controlled during the casting process, and the positive and negative tolerance is kept at ± 5 degrees, which effectively ensures the density of finished combine harvester finger products. So as to provide 100% qualified combine fingers products for our customers.

Heat treatment and quenching process of combine fingers manufacture

In order to produce qualified combine finger products with precise size, Cothda, as one of the most experienced harvester finger manufacturers & suppliers, usually adopts temperature control heat treatment equipment.

Combined finger will produce stress after heat treatment, and the shape, size, and performance of the combine fingers will be changed.

With years of experience, the combine finger manufacturers can control the material and process to make the dimension error of combine parts reach the international standard tolerance after hardening.

The key point of heat treatment of iron castings is heating and cooling. Kubota 988 Combine Finger

Usually, because of the inconsistency of cooling rate and time between the surface layer and the core of metal parts, the temperature difference will result in uneven volume expansion and contraction and stress, i.e. thermal stress.

In order to solve the stress problem.

For ages, we have been involving fixing technical problems of metal quenching of combine finger products. So, In the dynamic temperature rise and fall, the combine finger parts do not deform and reach the hardness and toughness we want.

For many parts such as combine fingers and other harvester parts, quenching is a common and key process. parts of combine harvester

However, the quenching level directly determines the quality in our production of combine parts.

Good combine finger quenching process requires not only the most advanced tunnel temperature control boiler and other equipment, but also need decades of harvester parts production data and trouble-shooting experience. Combine finger Description 008

We supply high quality combine harvester parts for agricultural machinery manufacturer, automobile manufacturer, tractor manufacturer, etc. We are confident in our producibility of combine fingers and other combine cutter bar parts.
