The right angle of the spring after grinding is managed according to internal standards with a precision of JIS Class 2 or higher.
The material used is "Piano Wire Type A, SWP-A." The wire diameter is Φ9.0. After forming the spring, it undergoes heat treatment, and both ends are ground flat. The purpose of grinding the ends is to improve the seating of the spring and ensure perpendicularity. The perpendicularity of the spring after grinding is managed according to our internal standards, maintaining a precision of JIS Grade 2 or higher. (Note: JIS Grade 2 perpendicularity = 0.05Hf = 2.9 degrees) To prevent rust, a cationic electrodeposition coating is applied. If you have any issues with "springs," please feel free to consult us. Our technical staff will respond carefully.
