About the Process

Hand polishing is a manual process where the part is sanded, then buffed on a set of abrasive wheels or rouges to achieve the desired surface finish. This is a subtractive process that removes material in order to eliminate scratches and other imperfections.

Design considerations

  • Radiused corners and edges generally produce better results than sharp ones
  • Wall thicknesses less than 1.5mm do not hold up as well during polishing
  • Internal or hard to reach features (including threads) are difficult or impossible to polish
  • Very tight tolerances, reamed holes, and threads may need to be excluded from polishing

Manufacturing Process Selection: A Guide to Choosing the Right Production Methods

The manufacturing process you select impacts part cost, lead time, achievable tolerances, material options, and how easily you can iterate your design. The wrong choice doesn’t just affect the prototype; it can also lock in cost and quality constraints that compound through the entire product development life cycle. Making this decision requires balancing competing technical […]

The Impact of AI in Mechanical Engineering

Artificial Intelligence is no longer on the horizon for mechanical engineers—it’s already on our desktops, inside our CAD tools, and embedded in robotics on the factory floor. When I started working as a mechanical engineer 15 years ago, I didn’t think much about AI someday reshaping my job. Now the question has shifted from will […]
