Spiral Cutter Head for Wadkin Bursgreen Super 400 Surface Planer S400 with 102 Carbide Inserts
Upgrad their Wadkin Bursgreen Super 400 Surface Planer S400 with Sheartak spiral cutter heads and enjoy the following key benefits:
-
Smoother Finish with No Tear-Out: Each insert is set at a slight angle, delivering a shear cut that produces a staggered cutting action. This is far superior to the single, straight cut of traditional knives. The combined shear and staggered cuts prevent tear-out and create a glossy finish, even on highly figured hardwoods.
-
Significant Noise Reduction: The spiral cutter head’s staggered cutting pattern results in less noise, as only a few inserts cut at a time.
-
Longer Life Than High-Speed Steel: The 15x15x2.5mm inserts are crafted from sintered tungsten carbide, which is much harder than high-speed steel. Each insert has four cutting edges, significantly extending the lifespan of the cutter head—over 10 times longer than high-speed steel.
-
Simple to Replace: The precision-ground inserts have a tolerance of +/-0.0004" (or +/-0.01mm) and are fully interchangeable. Replacing them is quick and easy—just loosen the screw, rotate the insert 90° to use a new edge, and tighten it back in place. This process can save up to 30% in production time.
-
Better Dust Extraction: The spiral cutter head produces smaller, shorter chips, which improves dust collection and extraction efficiency.
-
Cost-Effective: With its smooth finish, reduced sanding needs, and no requirement for sharpening, the spiral cutter head offers excellent value and quickly pays for itself.
Kit Includes:
- Pre-installed carbide inserts
- 5 additional carbide inserts
- 5 extra Torx screws
- 1 T-handle wrench
Please note: This cutterhead is made to order
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.
