Premium Spiral Cutterhead Jointer Solutions
Sheartak Tools Ltd. manufactures precision-engineered spiral cutterhead solutions specifically designed for Chevpac Machinery equipment. Our cutter head upgrades transform standard Chevpac planers and jointers into high-performance systems with significantly enhanced cutting quality. Each spiral cutterhead jointer conversion features premium carbide inserts as mechanical components arranged along helical grooves, creating a true shear-cut that dramatically reduces noise and eliminates tear-out on all wood species.
These mechanical component upgrades deliver exceptional surface finishes that enhance the solid performance of Chevpac Machinery woodworking tools. The advanced cutter head design provides more than 10 times the blade life of traditional straight knives. When an edge dulls on your spiral cutterhead jointer, simply rotate the carbide insert 90 degrees for a fresh cutting edge—no blade removal, no sharpening services, no complicated adjustments required.
Professional Mechanical Components for Industrial Equipment
Sheartak Tools Ltd. manufactures every Chevpac Machinery spiral cutterhead using high-tensile strength alloy steel paired with sintered tungsten carbide inserts. Each cutter head is precision-ground to tolerances of ±0.0004" (±0.01mm), ensuring seamless integration with your Chevpac equipment including Model CT-318 12" surface planer and other woodworking machinery configurations. Our mechanical components complement the quality and comprehensive service that have made Chevpac a reliable source for industrial and woodworking tools.
Whether you own a Chevpac planer, jointer, or combination machine, our spiral cutterhead solutions deliver professional reliability and performance. These woodworking tools reduce operational noise by up to 80%, improve surface quality dramatically, and maximize the efficiency of your Chevpac Machinery equipment, maintaining the practical value proposition and comprehensive product support that define this trusted industrial supplier serving workshops throughout New Zealand and international markets.
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.
