The major advantage of CBPB is an ease of machining them. Despite the fact that CBPB are much more firmer than particle boards, they can be machined by all usual wood processing tools. For professional machining of the plates and getting a qualitative machined face it is necessary to apply the tools milling plates of which are made of hard metal. CBPB can be cut, milled, bored and ground.
The boards can be cut at the plant taking into account customer’s requirements. If there is a necessity to cut a plate at the site, it is recommended to use cutting tools with the plates made of hard metal. A lug of a sawing disc from the side of an undersurface must be minimum for the cut edges look impeccable.
|Stationary shape sawing (horizontal and vertical position)||saw blade Ø 250 - 400 mm|
|quantity of cogs 48 - 72|
|Sawing with a hand circular saw blade:|
|thickness of a plate <12mm||saw blade Ø 250 mm|
|quantity of cogs 48 - 72|
|thickness of a plate >12mm||saw blade Ø 250 mm|
|quantity of cogs 36 - 60|
Attention! Cutting of the boards generates a lot of dust, that is why it is necessary to use dust exhaust apparatus and means of aspiration.
In accordance with the client’s documentation boring of through holes with dimples for screw heads can be done at the plant. To bore holes manually one needs to use: - borers with hard metal tips, having high wearing capacity, - boring systems with electronic rotation speed control.
|Boring with the help of a hand drill|
|For separate holes||Borer HS 2,5-3,0 mm||Rotation frequency of a borer: 1300 min|
|For continuous duty||Borer made of hard metal ВК6-ВК8||Rotation frequency of a borer: 1300 min|
Milling of CBPB TAMAK is recommended to be done at the plant. However if plates application peculiarities require their milling at sites directly it is necessary to follow the recommendation (set forth below):
|Milling at the plant is made by end-milling cutters, equipped with solderings made of hard metal, installed on a routing machine.||Rotation frequency of a milling instrument in the range 9000-12000 min|
|Milling at sites is made by end-milling cutters, equipped with solderings made of hard metal installed on an electrical manual mill.||Rotation frequency of a milling instrument in the range 12000-16000 min|
Attention! It is necessary to have dust and chip extraction from the milling zone.
CBPB ТАМАК have a smooth surface that is why there is no grinding at the plant. All the more such kind of a plate surface treatment breaks the upper layer and opens a structure of a plate, increases its water absorption and thus leads to deterioration of physical-mechanical properties.
At the same time when assembling plates, local roughness (which should be removed by grinding) can emerge at the junctures. One can apply manual grinding tools: manual vibrogrinding machine, manual belt grinding machine. The grain number of grinding material must be №16-№25.
Attention! When grinding it is necessary to apply industrial exhaust fans and other means of dusting.
