La raboteuse Black & Decker 90 mm est un outil très recherché par les menuisiers en raison de son boîtier robuste en aluminium robuste qui réduit les vibrations. Cependant, il est livré avec une lame à un seul tranchant qui nécessite un affûtage fréquent.
La tête de coupe en spirale Sheartak, quant à elle, est une mise à niveau spécialement conçue comprenant 16 plaquettes en carbure, chacune avec quatre arêtes vives. Les inserts sont inclinés pour une coupe par cisaillement, ce qui donne une finition supérieure sans aucune déchirure. Lorsqu'un bord devient émoussé ou ébréché, tournez-le simplement à 90 degrés. Remplacez l'ensemble de l'insert uniquement lorsque les quatre bords sont usés. Ces inserts en carbure peuvent durer des mois, voire des années, vous évitant ainsi les tracas liés à l'affûtage et à la configuration des lames.
De plus, la fonction de réduction silencieuse du bruit élimine le besoin de protection auditive et la finition de surface vitreuse réduit le travail de ponçage jusqu'à 3/4, dans la plupart des cas. En fait, vous n’aurez peut-être même pas besoin de poncer votre travail.
Commandez maintenant et recevez cinq inserts supplémentaires pour de futurs remplacements, ainsi qu'une paire de roulements scellés haut de gamme pré-montés pour une mise à niveau simple et directe. Découvrez les avantages de la technologie de coupe hélicoïdale avec cet outil fantastique.
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.
