The Sheartak Spiral Cutterhead offers exceptional advantages for your Rockwell 20" Planer RC-51, delivering superior performance and efficiency. Here are the key benefits of this innovative spiral cutterhead:
True Shear Cut: Provides a significantly glossier surface finish compared to other types of spiral cutterheads.
High-Precision Carbide Inserts: Equipped with 4 cutting edges per insert for optimal performance and longevity.
Extended Knife Life: Tungsten carbide knives last 8 to 10 times longer than traditional HSS knives.
Quick Edge Replacement: No need for sharpening—simply rotate the insert 90 degrees to reveal a fresh cutting edge in seconds, saving you valuable time.
Reduced Noise Levels: Enjoy a quieter and more pleasant working environment.
Improved Dust Collection: Produces smaller chips, making dust collection more efficient and effective.
Sheartak Cutterhead Kit Includes:
* High-tensile strength alloy steel cutter block.
* 210 carbide inserts pre-installed on 10 spirals.
* 5 extra carbide inserts and 5 extra screws provided as spare parts.
* 1 wrench for easy installation and maintenance.
Upgrade your planer with the Sheartak Spiral Cutterhead for unmatched precision, durability, and ease of use.
The Rockwell RC-51 and Delta RC-51 are not the same. We will verify the dimensions with you to ensure you receive the correct cutterhead. Simply going by "RC-51" is not sufficient, as it may not be compatible. Let us confirm the details to avoid any issues.
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
If you add the bearings to your order, we will preinstall them for you when premounting is possible, saving you the hassle of doing it yourself.
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.
