The precision cutting machine is used for precise and deformation-free cutting of “Metals, Ceramics, Electronic Components, Crystals, Composites, Biomaterials, Sintered Carbides, Minerals, etc.”
Akasel precision cut-off wheels are optimised for high precision cutting of different materials. They are as thin as possible in relation to the diameter to remove an absolute minimum of material, a critical factor when sectioning expensive materials. Thin cut-off wheels limit the thermal damage and mechanical deformation during cutting. This again reduces the following grinding and polishing time.
What is the common material used in precision cutting?
There are two types of material used in precision cutting which are:
- Cubic Boron Nitride (CBN)
- Diamond
1. Cubic Boron Nitride (CBN)
- CBN is recommended for cutting hard metals, specially iron and steel
- CBN blades provide significantly reduced cutting times for tough, gummy materials, such as lead and titanium
- CBN are not recommended for ceramics and other non metallic materials
- CBN will provide precise cutting capability on difficult to cut samples/materials
2. Diamond
- Diamond is the hardest material on earth (diamond blades) will cut hardest material
What is the process of precision cutting?
- Select the appropriate precision wheel
- Secure specimen. Improper clamping may result in wheel and/or specimen damage
- Check coolant level and replace when low or excessively dirty. Note precision wheels break down during cutting and thus produce a significant amount of debris
- Allow the precision wheel to reach its operating speed before beginning the cut
- A steady force will produce the best cuts (weight selection) and minimize wheel wear characteristics, as well as maintain sample integrity (no burning)
- When sectioning materials with coatings, orient the specimen so that the wheel is cutting into the coating and exiting out of the base material, thereby keeping the coating in compression.

What is the common consumables used in precision cutting process?
- Precision wheel : CBN, Diamond, and Abrasive
- Use oil soluble : Metal
- Use water soluble oil : ceramic
- Dressing stick : Aluminum oxide, Remove chip between diamond particle
