Shearak spiral cutterheads for Laguna Mplan 1510 16'' Planer are a specialized woodworking tool designed to improve cutting performance and durability in planers and jointers. They feature unique characteristics that make them popular among woodworkers. Here are some of their key features:
Spiral Design. The cutterhead is designed in a helical or spiral shape, ensuring smoother and quieter cutting compared to traditional straight knives.
This design reduces tear-out and creates a superior finish on both soft and hard woods.
Carbide Inserts
The cutterhead is equipped with replaceable carbide inserts instead of traditional knives.
Carbide is more durable, staying sharp much longer and requiring less frequent replacements.
Each insert typically has multiple cutting edges and can be rotated when one edge becomes dull, extending the tool’s life.
Reduced Tear-Out. The spiral layout and positioning of the inserts allow for a shearing action, which minimizes tear-out, especially on challenging grains or exotic woods.
Quiet Operation. Compared to straight knives, spiral cutterheads are significantly quieter, making them more suitable for shop environments.
Easy Maintenance
Changing inserts is simple—only the affected insert needs replacement, rather than the entire set.
No need for blade alignment or sharpening; a quick rotation of the insert restores optimal performance.
Efficient Chip Removal. The spiral shape assists with directing chips away from the cutting area, improving dust collection and preventing clogging.
Versatility
Please note: dimension verification is required for this model
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.
