Feature

• There are two main methods for measuring workpiece surface roughness.
• You can use a mechanical roughness measuring machine for numerical values or visually and tactually compare a pre-made standard surface roughness plate to the workpiece.

  Nippon Metal Electrocasting’s ‘Arasa Standard Plate’ is a comparative surface roughness standard plate.

• It involves both visual and tactile comparisons.
• The tactile method appears more accurate, especially when using the fingertip for better sensitivity.
• This approach is widely used in production environments.

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.

Specifications

Feature

• This device targets the most used sections.
• Those sections come from various processing methods and roughness levels outlined in the JIS standards.
• Its purpose is for comparison and measurement with the actual object.

Specifications

• Paper finish Rmax(S)/μmRz: 0.4, 0.8, 1.6, 3.2, 6.3
• File finish Rmax(S)/μmRz: 3.2, 6.3, 12.5, 18, 25
• The plate serves for checking the finish roughness and during machining.
• The standard plate’s dimensions are 21×14 mm.
• The body’s dimensions are 182×47×2.8 mm.
• The content includes one piece.

Features

• You can measure roughness by comparing a standard plate to the actual product.
• You have two options: using sight or touch.
• For most surfaces, the touch method works well.
• The JIS standards agree, especially when you measure the highest peaks and valleys.For a more sensitive touch, use your fingernail instead of your fingertip.
• Or, you could use a pencil’s tip for a gentle scrape.
• But, if you’re checking surface shine, you must look at the surface.
• Usually, you can spot or feel roughness levels up to about 0.8S.
