Therefore, the surface roughness of the sphere is greatly improved. For example, if the material is 1CrlgNi9Ti, turning to the upper limit of the nominal size, the surface roughness Ra is 6.3 m, and the roundness error is 36 pro, the machine speed is 240 r/min, and the honing head speed is 60 m/rain. 180 brown corundum stone. After honing for 2 minutes, the surface roughness R value of the sphere can reach 0.8 m and the roundness error F is 4 m. In order to ensure equal honing effect, it is better to make the honing head or ball rotate reversely for half of the whole honing process. The ball honing device has simple structure, convenient operation, no special equipment is needed, and the ball can be honed on an ordinary lathe, which is particularly suitable for batch production. If the honing head is replaced, the device can hon the pneumatic ball valve ball with a nominal diameter of 50~150ram. It has obvious technical and economic benefits for improving the finishing efficiency of the sphere, improving the surface roughness and geometric shape accuracy of the sphere.

Two way integrity of stainless steel pneumatic butterfly valve
We constantly believe that integrity is the best publicity for stainless steel pneumatic butterfly valve enterprises, so we continue to uphold the principle of integrity. But at this time, I want to say that honesty is two-way. Not only do we need integrity, but customers also need integrity.
Often, in order to ensure the rights and interests of both our customers and us, we will sign contracts in advance and strictly follow them. However, during the execution of the contract, there will inevitably be problems in some links: for example, we will try our best to deal with the delay in delivery due to weather or other force majeure and deliver goods to customers as soon as possible. This is our duty.
However, some problems are beyond our control, and are also a common problem for many enterprises: it is difficult to collect the balance.
At present, the company has encountered a big problem: a few months ago, we provided our product: stainless steel pneumatic butterfly valve for an enterprise in Guizhou. After we delivered the goods to the customer's place, the customer has not settled the balance. After several unsuccessful phone calls, the company sent one of our deputy business managers to communicate with the customer face to face, hoping that the balance would be received as soon as possible. What I didn't expect was that I never saw customers. The answer is that the guidance is not here, wait. I never thought it would be more than a month, but I still haven't seen the customer, let alone settle the balance. The expenses incurred in the process: board and lodging expenses, communication expenses, and transportation expenses, which add up to a large sum, not to mention the problem of personnel waste.
In fact, sometimes we can understand the temporary difficulty of capital turnover of customers, and give them some room to ease, but we always hope that customers can treat us with a sincere heart. People always say that "customers are God", and we hope that when we treat customers as God, customers can treat us with understanding and understanding.
Honesty is the most important thing. Whether you are a buyer or a seller, or whether you are a common person or a celebrity, it is the yardstick that we always adhere to. Only in this way can there be a harmonious society and life.
