La raboteuse GENERAL 13'' originale 30-005 HCMI comprend 26 lames en acier rapide (HSS) à deux tranchants qui se vendent 79 USD les 10 pièces. Cependant, les lames HSS ont tendance à s'user rapidement et leur disposition n'est pas hélicoïdale. En revanche, la tête de coupe spirale Sheartak pour le 30-005 HCMI comporte 40 plaquettes en carbure, chacune avec quatre arêtes de coupe. Les inserts en carbure ont une durée de vie 50 fois plus longue que les lames HSS, ce qui en fait une option plus durable. De plus, Sheartak a orienté les 40 plaquettes en carbure le long de quatre rainures hélicoïdales pour une coupe par cisaillement pur, ce qui se traduit par une finition de surface supérieure. Les plaquettes en carbure Sheartak sont livrées dans une boîte et se vendent 36 USD ou 45 CAD. En passant à la tête de coupe spirale Sheartak, les utilisateurs peuvent obtenir de meilleures performances et récupérer rapidement leur investissement.
Le kit de têtes de coupe en spirale comprend :
* Bloc de coupe en acier allié à haute résistance à la traction.
* 40 plaquettes carbure installées.
* 5 inserts en carbure supplémentaires et 5 vis supplémentaires gratuites comme pièces de rechange.
* Une paire de roulements scellés haut de gamme.
* 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.
