Upgrade your Bernardo SP 200 PN Surface Planning Machines with Sheartak spiral cutter heads to enjoy a multitude of benefits: Achieve a flawless finish with zero tear-out. The Sheartak spiral cutter heads feature 40 carbide inserts positioned along five spirals, ensuring each knife cuts at a slight angle for a shear cut. This staggered cutting action outperforms traditional straight cuts, eliminating tear-out and leaving a lustrous surface even on the most intricate hardwood grains. Experience significantly reduced noise levels. The innovative design of the spiral cutter head allows for a staggered cutting pattern, minimizing noise during operation. Enjoy extended tool lifespan. With over 10 times the longevity of high-speed steel, the sintered tungsten carbide inserts (15x15x2.5mm) boast exceptional hardness and durability. Each insert boasts four edges, maximizing utility and minimizing downtime. Simplify maintenance with easy interchangeability. Precision-ground knives with a tolerance of +/-0.0004" or +/-0.01mm ensure consistent performance. Changing inserts is a breeze – loosen the screw, rotate 90° for a fresh edge, and securely tighten in minutes. Streamline dust extraction processes. The spiral cutter head generates thinner, shorter chips, making dust extraction more efficient and hassle-free. Experience cost-effectiveness. By producing a smooth finish and reducing or eliminating the need for extensive sanding or sharpening, the Sheartak spiral cutter heads offer exceptional value. The initial investment pays for itself in a short timeframe, making it a smart choice for any woodworking operation.
Sheartak Cutterhead Kit includes:
* High tensile strength alloy steel cutter block.
* 40 carbide inserts installed on 5 helicals.
* 5 extra carbide inserts & 5 extra screws free as spare parts.
* 1 Wrench
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.
