Knife Grinder／
ARTESA I V94-AC
A large-volume cooling system stops thermal distortion during grinding. This makes it easier to grind knives with excellent straightness, which can be expected to improve and stabilize veneer quality. Three types of grindstones (rough, finishing, and back grinding) and automatic adjustment of grinding direction (up or down cutting) provides faster honing and improved precision.
Standard Specifications
- Effective knife dimensions
- Length1,000mm - 3,320mm
- Width125mm - 210mm
- Thickness12mm - 25mm
- Possible knife angle
- Face0°10’〜91°
- Back0°〜11°
POINT
- Extreme blade straightness of variance within 0.05 mm over 3 m
- High performance cooling enables high-speed heavy-duty grinding
- Full commitment to precision means superior blade reproducibility
-
Large-volume coolant system for high straightness precision
The large-volume coolant system mitigates grinding friction heat and suppresses thermal distortion of the blade during griding. The result is a high straightness precision of less than 0.05 mm (0.002 inch) variance over 2,750 mm (9 feet). This produces high-quality veneer with smooth surfaces and more consistent thickness.
-
Two grinding methods (up and down cuts)
Uses three kinds of grindstones (blade face: 46#, 150#; blade back: 150#). Automatically switches between up cuts and down cuts, for more efficient grinding compared to conventional machines. Down cut finishing produces blades with no chips and high straightness.
-
Possible to sharpen many kinds of knife
Can be easily adapted to grind many kinds of knives, not just veneer knives, including chipper knives, clipper knives, composer knives, flaker knives, and so on.
-
Fully automatic operation
Input a grinding pattern to fully automate the entire grinding process. The use of patterns enables operators to consistently reproduce uniform knife angles.
Knife Honer／
ARTESAII V95-AC
Precise air control enables ultra-high accuracy edge cutting with 20-micron land width.
Honing patterns are automatically stored, making it easy to reproduce blade shapes corresponding to the raw timber, which in turn improves and stabilizes veneer quality.
Standard Specifications
- Effective knife dimensions
- Length700mm - 3,320mm
- Width125mm - 210mm
- Thickness12mm - 25mm
- Possible knife angle
- Face19°〜55°
- Back0°〜45°
POINT
- Precise air control enables ultra-accurate honing with land widths of 20 microns.
- Up to 6-stage edge cutting on each of the front and rear of the blades
- Optimize blade shapes for the type of wood (up to 39 patterns)
- Sharpen three knives in one hour
-
Our proprietary air balancing mechanism enables high-precision honing
Proprietary air balancing mechanism stabilizes grinding pressures, thus enabling smooth copy honing to form land widths of 0.02 mm (0.00008 in). Sharpening takes into account the balance of forces applied to the cutting edge to produce knives with excellent sharpness and edge retention (durability). Grindstones: #1000 and #8000 (front and rear)
-
Improved knife sharpness/durability
Multiple knife angles can be added along the knife edge to customize the knife for different types of logs. This enables even more consistent and high-quality veneer peeling. in addition, forming an oval shape with numerous small knife angles on the knife's cutting edge improves durability compared to normal honing processes.
-
Save/manage honing patterns
The hardness of raw timber differs depending on the type of tree, and each type requires a certain blade shape. The Knife Honer ARTESA II can create precise stepped angles on the face and reverse of the blade, and save up to 39 sets of design data for these patterns. As well, cameras can be used after honing to verify and manage the cutting edge.
-
Fully automatic operation
As with the Knife Grinder ARTESA I, grinding patterns can be input to fully automate the entire grinding process.
