Accuracy control for roll forming machine equipment,make precise goods
Many customer are really care about their products after roll forming. Customer’s need beautiful and smooth profiles which help their business cause you know no one like bad products. So what we should do is to guarantee the accuracy of their products which mean guarantee the accuracy of our roll forming machine. It include the profile size accuracy, the output length accuracy and cutting accuracy.
First, we guarantee the profile size accuracy, the main point is to guarantee the designing of the rollers and shaft. All the rollers and shafts should be stricted control according to customer’s profile sizes and customer’s material. Usually the tolerance of rollers should be ±0.05mm to guarantee the profile sizes. Also the gap of the roller and shafts should be controled in one small size, for example the gap should be ±0.1mm. If the gap is too big, the forming material will go to wrong direction which very bad situation. If the gap is too small, the rollers can’t installed on the shaft.
Second,the output length accuracy. It is not so bad than the profile tolerance. But we should keep it in one acceptable range. For example, the tolerance is ±2mm for some products. But there mush be some higher requirements from customers no matter if it is necessary, customers are always going for perfect! Of course they will pay the price. Some of our measures like change the chain drive tobe gearbox, change the commom motor to be servo motor and change the Combination of the chain to be single chain.,etc. The purpose is to reduce the inertia when cutting formed products.
The cutting accuracy is also very important for customers cause the end oof profile may deformed after cutting. So we should think about the cutting way, for example change the saw cutting to be hydraulic cutting, or change the hydraulic cutting to be saw cutting. That’s depend on customer’s material and products. Aslo how to make the cutting mould is also very important. The tolerance should me little to guarantee accuracy. But i hope customer to understand that usually the little deformation at the cutting end is can’t avoid no matter in China or other countries.
So if we guarantee such accuracy, we should be sucessd in making one high standard equipment for our customers. That’s why many customers come back again for second cooperation with us. I hope more and more potential customer can know us and understand us. We are going for quality, but keep cheap price. Help customer is helping ourselves.
