Tête de coupe en spirale Delta 37-220 6" Dégauchisseuse est équipée de 30 inserts en carbure. Chaque insert en carbure a 4 bords indexables. Les inserts en carbure sont légèrement inclinés par rapport à l'alimentation de la planche, ce qui génère une coupe de cisaillement, élimine l'arrachement et laisse une finition de surface de meilleure qualité sur le bois tendre et le bois dur très figuré. Cela réduit considérablement le bruit de fonctionnement.
Faites simplement pivoter le quart de cercle de l'insert si un bord est émoussé ou entaillé. Vous aurez un nouveau tranchant. Jetez les plaquettes en carbure bon marché uniquement lorsque les quatre bords sont concernés. Pas besoin d'affûter ces inserts bon marché. Cela réduit considérablement les temps d’arrêt. Les têtes de coupe en spirale Sheartak réduisent les trois quarts de votre travail de ponçage et consomment moins d'énergie. Les têtes de coupe en spirale éliminent les copeaux courts de manière échelonnée et évitent l'obstruction de la poussière au niveau du port du capot. L'extraction des poussières est considérablement améliorée. Les têtes de coupe en spirale Sheartak peuvent rembourser votre investissement initial en un rien de temps.
Le kit de têtes de coupe en spirale comprend :
* Bloc de coupe en acier allié à haute résistance à la traction.
* 30 plaquettes carbure installées.
* 5 inserts en carbure supplémentaires et 5 vis supplémentaires gratuites comme pièces de rechange.
* 1 clé
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.
