SECTION 6: METAL CUTTING

Workpiece

Inspection

Some metal workpieces are not safe to cut with a vertical metal cutting bandsaw; instead, a differ- ent tool or machine should be used.

Before cutting, inspect the material for any of the following conditions and take the neces- sary precautions:

•Small or Thin Workpieces: Small or thin workpieces are dangerous to cut if held by hand—avoid cutting these workpieces if possible. If you must cut a small or thin workpiece, attach it to or clamp it between larger scrap pieces that will both support the workpiece through the cut and keep your fin- gers away from the blade. Some thin sheet metals will not withstand the forces from this bandsaw during cutting; instead, use a shear, nibblers, or sheet metal nippers to cut these pieces.

•Round/Unstable Workpieces: Workpieces that cannot be properly supported or sta- blized without a vise should not be cut on a vertical metal-cutting bandsaw. Examples are chains, cables, round or oblong-shaped workpieces, workpieces with internal or built- in moving or rotating parts, etc.

•Material Hardness: Always factor in the hard- ness of the metal before cutting it. Hardened metals will take longer to cut, may require lubrication, and may require a different type of blade in order to efficiently cut them.

•Tanks, Cylinders, Containers, Valves, Etc: Cutting into containers that are pressur- ized or contain gasses or liquids can cause explosions, fires, caustic burns, or machine damage. Avoid cutting any of these types of containers unless you have verified that the container is empty and it can be properly sup- ported during a cut.

•Magnesium: Pure magnesium burns eas- ily. Cutting magnesium with a dull blade can create enough friction to ignite the small magnesium chips into a fire. Avoid cutting magnesium if possible.

Cutting Tips

•Keep the upper blade guide assembly adjust- ed to within 1⁄4" of the workpiece.

•Avoid overheating your blade. Keep an oil can nearby and squirt the blade near the cut- ting area when it gets hot or you see a small amount of smoke. Different metals require different types and amounts of lubrication.

•Replace, sharpen, and clean blades as nec- essary. Make adjustments periodically to keep the saw running in top condition.

•Use light and even pressure while cutting. Light contact with the blade makes it easier to follow lines and prevents extra friction.

•Avoid twisting the blade when cutting around tight corners. Allow the blade to saw around the corners.

•Misusing the saw or using incorrect tech- niques is unsafe and results in poor cuts. Remember—the blade does the cutting with the operator’s guidance.

•Never start a cut with the blade in contact with the workpiece, and do not start a cut on a sharp edge.

•Pay attention to the characteristics of the chips when cutting—they are good indicators of proper blade speed and feed rate. Page 38 shows the basic chip characteristics and what they mean.

•Use the right blade for the cutting task.

G0640X specifications

The Grizzly G0640X is a robust and versatile table saw designed for both professional woodworkers and hobbyists seeking to complete a variety of woodworking projects with precision and ease. Known for its durability and a variety of advanced features, the G0640X stands out in the marketplace for its exceptional performance capabilities.

At the heart of the G0640X is a powerful 3HP motor, which provides ample strength to cut through a wide range of materials, from hardwoods to engineered wood products. This motor is complemented by a dual voltage capability, allowing users to operate on either 120V or 240V power sources, which enhances versatility in different workshop environments.

One of the standout features of the Grizzly G0640X is its precision-ground cast iron table, which measures 30 inches by 48 inches. This expansive surface area ensures excellent stability and support for large workpieces. The smoothness of the tabletop allows for easy movement of materials, reducing friction and improving overall accuracy during cutting operations.

The saw also includes an advanced blade-raising mechanism, allowing for easy height adjustments while providing precision in blade depth settings. The rack and pinion system for the fence enhances the ease of making accurate adjustments, ensuring that users can achieve precise cuts consistently.

Safety is a prime consideration in the design of the G0640X. The saw features a heavy-duty cabinet-style base that guards against vibrations, providing a stable cutting environment. Additionally, the inclusion of a blade guard and riving knife enhances user safety during operation, reducing the risk of kickbacks and injuries.

Another noteworthy aspect is the dust collection system integrated into the design, which helps maintain a cleaner workspace by effectively capturing sawdust and debris during cutting. This reduces cleanup time and promotes a healthier workshop environment.

In terms of mobility, the G0640X includes sturdy wheels and handles for easy transport within the shop or to job sites. Quality and craftsmanship are evident throughout the build, making it a reliable choice for those looking to invest in a long-lasting table saw.

Overall, the Grizzly G0640X table saw combines power, versatility, and safety features to cater to the needs of modern woodworkers. Its blend of advanced technologies and thoughtful design ensures consistent performance and satisfaction in woodworking projects of all scales.
