Arbre porte-outils hélicoïdal Sheartak pour combinée dégauchisseuse-raboteuse SCM Minimax FS 41
L'arbre porte-outils hélicoïdal Sheartak est conçu pour la combinée dégauchisseuse-raboteuse SCM Minimax FS 41, comprenant 102 plaquettes en carbure disposées sur cinq spirales. Le kit inclut cinq plaquettes en carbure supplémentaires et cinq vis de rechange pour des remplacements faciles.
Comparé aux arbres porte-outils traditionnels à lames droites, l'arbre porte-outils hélicoïdal Sheartak offre une finition de surface supérieure. Ses plaquettes à bords arrondis sont inclinées pour un effet de coupe en cisaillement, assurant une finition lisse comme du verre, même sur les bois très figurés ou tendres. Chaque plaquette a quatre arêtes de coupe et peut être tournée jusqu'à trois fois pour révéler une nouvelle arête tranchante, éliminant ainsi le besoin d'affûtage ou de réglage. Les plaquettes en carbure durent jusqu'à 50 fois plus longtemps que les lames HSS. De plus, les copeaux plus courts et plus fins produits par l'arbre porte-outils hélicoïdal améliorent l'efficacité de l'extraction de la poussière.
Tous les arbres porte-outils Sheartak sont livrés avec une garantie d'un an à compter de la date d'achat, couvrant les pièces et les défauts de fabrication (à l'exclusion des consommables).

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.
