Tête de coupe Sheartak pour dégauchisseuse-raboteuse hélicoïdale de table Craftex 13" modèle CX13HC
40 plaquettes de carbure indexables sont installées sur 4 spirales. Chaque plaquette a quatre bords ronds et tranchants.
Les plaquettes sont légèrement inclinées par rapport à l'alimentation de la planche, ce qui génère une action de cisaillement, par opposition aux têtes de coupe hélicoïdales directes et droites. La coupe par cisaillement laisse une finition beaucoup plus lisse et produit beaucoup moins de bruit.
Nos têtes de coupe sont garanties un an à compter de la date d'achat (les plaquettes de carbure sont des consommables et ne sont pas couvertes par la garantie).
La taille des plaquettes de carbure est de 15x15x2,5 mm R150, la taille des vis est de 10#-32TPI à tête Torx. La clé en T est une T25 standard. Ces pièces peuvent être facilement trouvées en ligne ou expédiées depuis notre entrepôt.
Les kits comprennent :
* Bloc de tête de coupe en acier allié à haute résistance
* 40 plaquettes de carbure installées sur 4 spirales
* 5 plaquettes de carbure, 5 vis et 1 clé en T
* Une paire de roulements étanches fabriqués au Japon.
Do I need to replace the original bearings?
If the bearings in your machine are in good condition, they can be reused by carefully removing them with a bearing or pulley puller. However, if the bearings are tightly pressed onto the shaft, removal may cause damage. To minimize this risk, we recommend replacing old bearings with our greased and sealed bearings, designed for long-lasting performance. For a smooth upgrade, we suggest adding the bearings to your shopping cart before completing your purchase.
We provide premium bearings from NSK, SKF, NTN, FAG, Timken. They are renowned for their high quality and performance, designed to provide durability and reliability in various applications
Do I need to to Add a Few Boxes of Carbide Inserts
We provide 5 carbide inserts and 5 screws as spare parts. However, many of our customers choose to purchase additional boxes, as the shipping costs for separate purchases can make it less economical.
Do I need a Torque Wrench?
To securely lock the carbide inserts, we recommend applying a torque of 48 to 52 Pound-Inches (or 5.42 to 5.88 Newton-Meters). (Note: 1 Newton-Meter is equal to 8.851 Pound-Inches, and 1 Pound-Inch is approximately 0.113 Newton-Meters.) It is crucial not to apply excessive torque, as this could cause the carbide inserts to crack or explode. On the other hand, using too little torque may result in the inserts not being properly secured, which could lead to cracks, shattering, or uneven height on the cutter block, causing ridges or lines on the board.
If one person is responsible for maintaining the machine, they can typically apply the same torque consistently without a torque wrench. However, when multiple people are involved in machine maintenance, ensuring uniform torque application can be challenging. For consistency and peace of mind, we recommend using a torque wrench.
What kind of steel the cutter block is made of?
The cutter block is constructed using GB/T 40Cr, a structural alloy steel of the same caliber as ASTM grade 5140, AISI 5140, SAE 5140, DIN 41Cr4, BS 41Cr4, JIS SCr440, and EN 41Cr4.The primary components of this steel are as follows: carbon (C) at a range of 0.37-0.44%, silicon (Si) between 0.17-0.37%, manganese (Mn) within 0.50-0.80%, and chromium (Cr) from 0.80-1.10%.
In terms of physical properties, this steel exhibits a tensile strength range of 115-234σb/MPa, a yield strength of 2σ 0.2 ≥/MPa, and an elongation capacity of 65 δ5≥ (%). It also has a HBS range of 123-321 and a HRC rating of 30.
This alloy steel is frequently utilized in low to moderately stressed components for machines, engines, and vehicles.
