Skills Of Yacht Polishing

Polishing and polishing is a necessary process for yacht construction, in order to make its appearance look more beautiful. At the same time, it is often used in the maintenance process, especially the grinding of teak. The polished yacht looks very new.

However, to achieve a very good polishing effect, we still need to pay attention to skills. There are different ways to deal with different situations.

1. Surface orange peel effect

Countermeasure: Reduce polishing pressure, use larger oilstone or wooden strips with diamond paste, use soft felt, polishing cloth with diamond paste, reduce sand number difference between grinding and polishing processes, check whether the hardness of the thrown mold is correct

2. Part of the surface is pulled out or surface fine pinholes appear

Countermeasures: Check whether the hardness of the thrown mold is correct, reduce the sand number difference between the grinding and polishing processes, use only 6 mm and finer diamond paste, use ordinary polishing abrasives thicker than 6 mm, and final optical mirror polishing, Hand-polished with high-quality paper towels and diamond paste Kemet brand 1-KD-C2

3. The polishing surface is not smooth enough

Countermeasure: If possible, use the KEMET brand leveling series, or: use GESSWEIN brand flat whetstone to smooth the surface; try to use the largest area of sandpaper, wood or whetstone

4. The polishing of the inner hole is not uniform enough

Countermeasure: For pre-grinded inner surface, try Kemet brand diamond paste 6-KD-C2 for spiral polishing

5. How to avoid scratches during polishing

Countermeasures: Separate abrasive tools with different sand numbers, one abrasive tool for one sand number, only one sanding direction, when changing the sand number, you must change the direction by 45 ° or 90 °. After polishing with lubricant and sandpaper, it must be cleaned before polishing with diamond paste and cleaning of parts and molds with complex shapes. You can use the KEMESONIC ultrasonic cleaning machine

6. Sub-surface marking appears on the polished surface

Countermeasure: Demagnetize the parts and re-polish

7. How to polish the runner or similar surface of the mold

Countermeasure: Use the GESSWEIN G-Glex wheel of appropriate size, this wheel of fine cotton cloth has added abrasive

8. When the mold is on the molding machine, how to remove the flaws on the polishing mold surface

Countermeasure: Use a high-quality paper towel or Selvyt cloth with diamond paste 1-KD-C2 or 3-KD-C2 KEMET to gently wipe the defect area, do not clean it with lubricating fluid or solvent.

9. How to polish the deep and narrow grooves of EDM

Countermeasure: Use ultrasonic polishing machine and KEMET super oil stone to grind and polish under the condition of proper lubrication

10. Coordination of press punch and die angle

Countermeasure: use GESSWEIN indicator (with different shapes and sizes), can be used with GESSWEIN manual polishing system

11. Small precision punches and dies edges must be polished and sharpened

Countermeasure: Different from grinding, use Kemet iron-on Kemet iron polisher to polish the edge surfaces of punch and die to make it sharp

12. How to polish a cavity (not inserted) after milling

Countermeasures: Treat the corners first, use GESSWEIN oilstone, then polish with hardwood strips and diamond paste 14-KD-C2, and then polish with diamond pastes 6-KD-C2, and then use cork strips or felts with Kemet 3-KD- C2 Diamond paste grinding and polishing, thorough cleaning between different sand number processes, after the corner parts are completed, then use the stone to polish and polish the main profile.
