Aluminium Polishing Machine

The Aluminium Polishing Machine is a surface polishing buffing machine for aluminum parts. High quality & Low Price & Free Consultation from the manufacturer

Due to the different aluminum alloys, variations in the final surface finish may occur. Variations may also occur by the type of buffing equipment used, the type and size of the buff wheels, the peripheral speed of the buff, the type of abrasive composition used, and the operator’s technique. When using automatic equipment, the operator technique is replaced by a mechanical system controlling such variables as pressure, time cycle,
conveyor speed, and contact time against the buffing wheel, resulting in a more consistent finish.

Aluminum and its alloys are soft metals with a high frictional coefficient. As previously discussed, tripoli or silica is used for a cutdown or cut-and-shine operation on aluminum. Calcined alumina compounds are used for shine on the aluminum surface

Buffing wheels and mops are essential components of buffing machines, providing the abrasive interface that polishes and refines metal surfaces. They are made from various materials, each with unique properties that influence their polishing action and suitability for different applications.

Types of Buffing Wheels and Mops

  1. Cotton Buffing Wheels: These are the most common type of buffing wheel, offering a balance of cutting action and finishing ability. They are suitable for a wide range of metals and polishing stages, from cut buffing to final polishing.
  2. Felt Buffing Wheels: Felt buffing wheels are softer and more flexible than cotton wheels, making them ideal for final polishing stages and achieving a high-gloss finish. They can also be used for polishing delicate surfaces or intricate shapes.
  3. Sisal Buffing Wheels: Sisal buffing wheels are made from a natural fiber that provides a more aggressive cutting action compared to cotton or felt wheels. They are primarily used for initial cut buffing stages to remove deep scratches, burrs, and imperfections.
  4. Buffing Mops: Buffing mops are similar to buffing wheels but typically have a more open structure, allowing for better ventilation and heat dissipation. They are often used for buffing large, flat surfaces or applying polishing compounds.

Selection of Buffing Wheels and Mops

The choice of buffing wheel or mop depends on several factors, including:

  1. Polishing Stage: The stage of the buffing process dictates the type of abrasive action required. Cut buffing requires a more aggressive wheel like sisal, while final polishing requires a softer wheel like felt or cotton.
  2. Metal Type: Different metals have varying hardness and reactivity to abrasives. For harder metals, a denser wheel like sisal may be needed, while softer metals may require a softer wheel like cotton or felt.
  3. Workpiece Shape and Size: The shape and size of the workpiece influence the choice of wheel or mop. For intricate shapes, a flexible felt mop may be suitable, while larger, flat surfaces may require a buffing wheel.
  4. Desired Finish: The desired level of polish dictates the fineness of the abrasives impregnated in the wheel or mop. For a high-gloss finish, finer abrasives are used, while a matte finish may require coarser abrasives.

Care and Maintenance of Buffing Wheels and Mops

Proper care and maintenance of buffing wheels and mops extend their lifespan and ensure consistent polishing performance:

  1. Cleaning: Regularly clean the wheel or mop to remove accumulated debris and polishing compounds. Use appropriate solvents or cleaning agents recommended by the manufacturer.
  2. Dressing: Dressing involves truing the wheel or mop to maintain its shape and balance. Use a dressing tool or a diamond-impregnated dressing stick to remove uneven wear and restore a consistent surface.
  3. Storage: Store buffing wheels and mops properly to prevent damage and maintain their shape. Hang them on dedicated hooks or store them in a protective container.
  4. Inspection: Regularly inspect buffing wheels and mops for signs of wear, damage, or contamination. Replace or repair damaged wheels or mops to ensure safety and performance.

Conclusion

Buffing wheels and mops play a crucial role in achieving the desired finish on metal surfaces. By understanding the different types, selection criteria, and maintenance practices, manufacturers and hobbyists can effectively utilize buffing wheels and mops to enhance the appearance, durability, and functionality of their metal products and projects.

Designations of Finishing grades done by an Aluminium Polishing Machine

  • Series (a) As fabricated. No buffing or polishing is required.
  • Series (b) Medium bright soft textured satin finish.
  • Series (c) Bright buffed finish over soft texture satin.
  • Series (d) Bright buffed finish on the original surface.
  • Series (e) Coarse directional satin finish.
  • Series (f) Medium directional satin finish.
  • Series (g) Fine directional satin finish.
  • Series (h) Hand-rubbed satin-type finish (small areas only).
  • Series (i) Brushed finish.
  • Series (j) Nondirectional satin finish.

The following recommendations are step-by-step instructions for obtaining the designated architectural finishes.

Aluminium Polishing Machine Grades

  • Series (b) Finishes Polish with a wheel coated with an abrasive and cement paste with 80 to 150 grit on sewn or ventilated buffs, lightly lubricated with a special bar or liquid lubricants. Buff speed 6,000 sfm. Final polish with a wheel coated with an abrasive and cement paste with 320 grit using the same buff and the same speed.
  • Series (c) Finishes Polish with an abrasive and cement paste-coated wheel, 320 grit on sewn or ventilated buff. Light lubrication with a special bar or liquid lubricant. Bright buff with clean working tripoli bar compound or liquid tripoli buffing compound on ventilated, sewn, or loose buff. Buff speed 7,000 sfm.
  • Series (d) Finishes Bright buff only over the original surface as for series (c) finishes. No prior polishing is required.
  • Series (e) Finishes Coarse satin finish with a greaseless compound of 80 grit over glue base buff sizing on a ventilated or sewn buff, or with liquid abrasive 80 grit on the same type buff. Lubricate the dried compound head with a special bar or liquid lubricant. Buff speed 6,000 sfm.
  • Series (f) Finishes Medium satin finish with greaseless compound, 120 grit, over a blue base buff sizing on ventilated or sewn buffs, or with liquid abrasive 120 grit on the same type buff. Lubricate the dried compound head with a special bar or liquid lubricant.
  • Series (g) Finishes Fine satin finish with greaseless compound, 150 grit, on a ventilated, sewn, or loose buff, or with liquid abrasive 150 grit on the same type of buff. Lubricate the dried compound head with a special bar or liquid lubricant. Buff speed 6,000 sfm.
  • Series (h) Finishes Hand-rubbed finish, using coarse steel wool lubricated with a special liquid lubricant. Final rubbing with No. 0 steel wool.
  • Series (i) Finishes Brush-type finish produced with string wheels coated with greaseless compound, 80 grit. String wheel speed 6,000 sfm. The buff head may require some light lubrication with a special bar lubricant, depending on the alloy of aluminum. Nylon-impregnated wheels are also used for this finish.
  • Series (j) Finishes: Brush-type finish produced with a string wheel coated with greaseless compound, 80 grit, but operated at a slow speed of 2,000 to 3,000 sfm.

May also require some light lubrication with a special bar lubricant. Again, nylon-impregnated wheels may also be used. When high-production satin finishing is required for series (e), (f), (g), and (i), use a liquid greaseless abrasive. Such compositions may be applied automatically with properly designed spray equipment. Light lubrication of the satin-finished head, when required, is done with non misting, low-atomizing spray equipment.
