Products and services
Facing the increasingly updated production mode and workpiece materials, tools have become an important process factor to optimize the production and processing technology,and the accuracy, cutting speed and working life of the tools play a decisive role in the production efficiency.We provide you with one-to-one exclusive technical service, tracking the whole process from the initial project design, product production to the practical application of the terminal, so as to efficiently and quickly solve the cutting problems encountered by customers in production.
Project design
When we undertake the project scheme, we organize and hold the project technical discussion according to the characteristics of the project and the needs of customers, and take the cost reduction and efficiency increase as the principle,combine with the latest processing technology, optimize the project scheme as far as possible, and provide the best scheme configuration for customers.
Operation & commissioning
SFD provides all kinds of general or customized upgrade inserts including PCD and CBN tip for standard and non-standard clamping tools, so that customers’ existing clamping tools can be more efficient.
Provide sample trial production service.
For each new project, we start from the essential needs of customers to develop the best design scheme and provide sample tool trial production services.
Service process
According to your repair needs,and on the premise of ensuring the quality of the original factory, we try our best to shorten the delivery period. After the grinding tools pass the inspection, we will send your tools back in the fastest way at the first time.
