Varnish Friction Testing Machine

The varnish friction testing machine simulates daily wear by driving a friction head to reciprocate on the coating surface through a motor. During testing, a fixed load and number of cycles are applied to evaluate the coating's scratch resistance. It is used to assess the durability of varnish on surfaces such as furniture and automotive interiors, ensuring that products meet usage requirements.
Selection
When selecting, consider the load range and reciprocating speed required by the test standards, matching the common load range of 0.5-20N. Choose the stroke and fixture based on the sample dimensions to ensure effective contact. The equipment should feature automatic counting and shutdown functions with an intuitive operation interface. Priority should be given to metal-structured bodies to guarantee test stability.
