The CAMEO® silver and gold disks are a special type of fine grinding disks with a highly constant material removal rate. CAMEO® DISK replace all pre-grinding processes for which 240-4000 grit abrasive paper is normally used. The patented honeycomb pattern of the CAMEO® DISK optimises the effectiveness of the sprayed-on BioDiamant liquids by ensuring that they are continuously and evenly distributed. The CAMEO® method guarantees optimum flatness for all types of samples.
The CAMEO® DISK is available in two different versions:
• CAMEO® DISK silver for medium-hard to very hard materials (> 200 HV)
• CAMEO® DISK gold for soft and non-ferrous materials
Advantages
• Easy to handle
• Cost-efficient – one CAMEO® DISK replaces a whole pallet of 240-4000 grain SiC paper
• The patented surface profile ensures even material removal
• The CAMEO® micro-container "meters” the applied abrasive agent and noticeably reduces the consumption of abrasive agent in comparison to other systems
• The disks have been developed for use on machines as well as for manual application. CAMEO® DISKS are compatible with all systems
• The stock removal rate of the CAMEO® DISKS is unsurpassed and enables samples to be prepared fast and with perfectly flat surfaces.
• Efficient – The CAMEO® method enables a vast range of diamond suspension with different grain sizes to be employed. This means that different materials can be prepared by using just one disk.
Applying the CAMEO® DISK
The CAMEO® DISKS are used for finegrinding soft to very hard metallographic samples. The choice between using the CAMEO® DISK silver or gold depends on the material properties of the sample. Together with the BioDiamant liquids, CAMEO® DISKS guarantee fast sample preparation with optimum surface flatness and excellent finishes.
Preparation
Automatic preparations:
In order to ensure that the samples are perfectly flat and that material is removed evenly when using the CAMEO® DISK, the specimen holder is positioned in such a way that the sample protrudes a few millimetres (max. 1/3 of the samples diameter) over the active working face of the disc on the inside and outside.
Manual preparation:
When using the CAMEO® DISKS manually, it must be ensured that the disks are applied evenly. In order to ensure that the disks wear evenly, the samples are moved from the edge of the disk to the middle during the grinding process.
Polishing agent
The CAMEO® DISKS are used in conjunction with the diamond liquids. When using the CAMEO® DISK silver, it is recommended to use 12 - 6 μm diamond liquids. The CAMEO® DISK gold should be used in conjunction with diamond liquids between 12 - 3 μm. When selecting the diamond liquids, the properties of the sample material must be taken into consideration. The diamond liquids must be sprayed-on at regular intervals.
Cleaning
In order to preserve the efficiency of the CAMEO® DISKS, it is recommended to clean the respective disk every time after using it under running water with a brush and dry it by using compressed air.
