GROOVE ROLLER
Groover roller is upper roller which is used with down roller to make groove. For roll grooving machine, upper roller is very important for the roll grooving machine, it controls the groove width and groove depth, sometimes, it controls A size of groove (it depends on its design). Pls refer to below photo to see the details
PRODUCT INTRODUCTION
We designed different grooving machines for different pipe with different sizes. Different grooving machines come with different upper rollers, all upper rollers from different grooving machines can not be interchanged. Customers have to choose correct upper rollers for different pipes, otherwise they will get incorrect groove.
PRODUCT QUALIFICATION
As is known to all, groove roller set is the key point of grooving machine, its hardness, its strengthen, its Precise diameter control will seriously affect the service life of machines, as well as the quality of machines, Upper roller is made of different material according to the demand. And different heat treatment is required according to different request from different manufacturers. For Tuwei, we make control plan for every processing. We ask for chemical composition inspection and Mechanical performance report before receiving the raw material. And we do random check for raw material to make sample analyzing to ensure the material is correct. We use vernier caliper and microcalliper to check whether the diameters match the dimensional tolerances or not, we use projector and CMM to check other diameters which common equipment can not used such as R angle and so on, we use microscope to check deposition of electroplated coating, we use Rockwell hardness tester to check its hardness. We make Initial Sample Inspection Report (ISIR) and first article inspection report (FAI) for the new designed rollers. Sometimes we make RT report as well. We have perfect control plan and testing equipment to ensure the consistency of products and drawings.
We do surface treatment for some special roller, some are blackened finished, some are electroplated with chromium, Zinc, Copper and so on. Also we control the coating thickness and hardness according to the drawings.
TUWEI ADVANTAGES
Now Tuwei has Standardized laboratory and Testing Center to meet daily testing need, Tuwei also has outsoucing testing department by cooperationg with some universities. Respond to the call of the government, through scientific research cooperation, the high-end resources of the school will be used to provide more effective services to companies. For Victaulic-Tuwei, Cooperating with universities can not only make full use of the advantages of excellent talents and knowledge accumulation, but also track the development trend of technology, reduce the cost of research and development, and improve the innovation ability.
With the development of technology and the renewal of testing equipment, the quality control of Victaulic-Tuwei has been further improved, and Victaulic-tuwei has made rapid progress in meeting the higher requirements of customers and will promote the continuous growth of new products.
