Polishing & Linishing

 

Polishing and buffing are finishing processes for soothing a work piece surface using an abrasive and a polishing mop. Technically, polishing refers to processes that use an abrasive that is glued to the wheel, while buffing uses a loose abrasive applied to the mop. Polishing is a more aggressive process whilst buffing is less harsh, producing a smoother and brighter finish. The type and amount of polishing and linishing required will be dependent on the final finish. Linishing is an engineering term that refers to a process of using grinding or sanding belt techniques to improve the flatness of a surface.

Quick Guide to Polishing Metals

There are many factors involved in polishing:
1. The condition of the metal will determine where you start.
2. The operating speed of the mop.
3. Quality of the metal – bad castings can cause big problems.
4. Abrasives obtain a good even surface with no deep scratches to ensure a deep mirror finish.
5. Make sure to remove the marks left from a previous process.
6. If possible, try to alter the direction of the polishing for each process (even if only by a few degrees).
7. Do not overload polishing mops with compound – you will deposit grease on the work surface.
8. Use wiping off powder after polishing to remove light grease and finger marks.
9. If the mop becomes clogged or dirty after use or from being left on the shelf for a while, use a mop dresser or wheel rake to remove all the unwanted old material.
10. Never wash mops in water.
11. Try and use one compound per mop.
12. Always use safety equipment – glasses and masks.
13. Extraction is recommended.
14. ALWAYS USE A HIGH QUALITY COMPOUND AND MOP FOR BEST RESULTS

Sisal Mops

Sisal Mops are used in fast cutting operations. Sisal makes a stiffer wheel than cotton therefore are commonly used after abrasive operations to obtain a semi-mirror bright finish prior to subsequent polishing operations. Sisal mops are often used on harder metals such as stainless steel, steel, hard brass and titanium.

Sisal Mops are used in conjunction with heavy cutting compounds such as Brushing Emery but can be used with medium cutting compounds such as Hyfin.

Sisal’s remove 240 -320 grit marks depending on which compound is used.

Green impregnation in the mop gives a slight hardness to the Sisal Wheel without making the Sisal too stiff and non- flexible. Ideal for first stage heavy duty polishing operations.

Swansdown Polishing Mops

Swansdown Polishing Mops are ideal for the final stage metal polishing when the cleanest and brightest finish is required. The very soft Calico material enables you to achieve a high quality finish on all types of metal especially stainless steel , gold and silver. Swansdown Mops are typically used with Rouge to produce a mirror finish.

Denim or Colour Stitch Mops

Demim or Colour Stitch Mops are harder than White Close Stitch Mops. They are commonly used for cutting operations on softer metals such as brass, aluminium and copper. Demim mops are suitable for the application of Coldax Cement to produce an abrasive mop coating.

Deburring Wheels

Deburring Wheels, also known as convolute wheels combine an even of coating aluminium oxide abrasive which allows a high cut -rate for a consistent finish. Deburring Wheels are used to deburr and finish many materials from metal to glass. The flexible construction conforms to help preserve irregular and contoured surfaces.

Bobbing Grease

Albo Bobbing Grease also Known as Tollow or Linishing Grease.

Albo Bobbing Grease is used in conjunction with abrasive belts and flexible abrasive wheels to minimise the operating temperature prolonging the life of the abrasive belt or abrasive wheel.

Ablo Bobbing Grease also prevents the belt or wheel getting clogged with dust increasing usage.

Wiping Off Powder

Wiping Off Powder is applied over the polished work to remove tenacious polishing compound residues. It is applied by a dry cloth. The powder is then removed by wiping off.

Coldax Cement:

Coldax Cement is a effective water based adhesive that sets quickly, is long lasting and does not soften under heat. Coldax Cement is easy to apply and is suitable for preparing abrasive coated felt bobs, polishing mops or any other type of abrasive wheel. Use with aluminium grit.
