La tête de coupe hélicoïdale pour la raboteuse générale 15'' 30-115MI est une excellente mise à niveau. Remplacez votre tête de coupe à lame droite. Le bloc de coupe est fabriqué en acier allié à haute résistance à la traction équivalent à l'AISI 291. La tête de coupe est livrée avec 72 pièces d'inserts en carbure indexables avec 4 bords droits. Tournez le couteau à 90 degrés pour révéler un nouveau tranchant. La durée de vie des couteaux en carbure est 10 fois supérieure à celle de la lame HSS. Chaque couteau a quatre bords. Le jeu de couteaux en carbure peut travailler 40 à 50 fois plus longtemps que les lames HSS. L'équilibrage dynamique est effectué après l'installation des inserts en carbure. Il améliore considérablement la finition de la surface et fonctionne parfaitement sur le bois massif et le bois tendre. Le bruit est réduit.
Le kit de têtes de coupe hélicoïdales comprend :
* Bloc de coupe en acier allié à haute résistance à la traction.
* 72 plaquettes carbure installées sur 4 hélicoïdales.
* 5 inserts en carbure supplémentaires et 5 vis supplémentaires gratuites comme pièces de rechange.
* 1 kit de têtes de coupe hélicoïdales comprend :
* Bloc de coupe en acier allié à haute résistance à la traction.
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.
