Feature

• When measuring the surface roughness of workpieces, you have two main methods.
• You can use a mechanical roughness measuring machine to get numerical values.
• Alternatively, you can visually and tactually compare a standard surface roughness plate.
• This plate is pre-made to match the criteria for each processing method.
• You compare it with the actual workpiece to make judgments.

  Nippon Metal Electrocasting’s ‘Arasa Standard Plate’ falls into the latter category.

• It serves as a comparative surface roughness standard plate.
• There are both visual and tactile comparisons, but the tactile method seems more accurate.
• Using the tip of your fingernail for comparison provides better sensitivity.
• This approach is widely adopted in production settings.
