Solid Wood Machining

What makes up hardwood lumber pricing?

It can be interesting to think about how lumber goes from the forest to the manufacturing plant. When you add each phase together you can get a good picture of the key elements that impact the overall total of the hardwood lumber pricing.

Here are a few other pointers that will help you to keep your glue applicator in good working condition between rebuilds.

CNC vs. conventional machining

While CNC machines make the process of designing, cutting, and building products more sophisticated and easy to carry out, what’s the real difference between using CNC and conventional machining?

Gluing, Laminating & Veneering

Roll coaters & glue spreaders: What’s the difference?

Roll coaters and adhesive spreaders (also called glue spreaders) are very similar, but there are some unique differences. Typically, adhesive spreaders will be used to bond two materials together and the applied adhesive will not be visible in the final product.  With a roll coater the coating typically will be visible in the final product and will have a certain pattern or look, for example a gloss finish.

Sanding and Finishing

6 tips for sanding veneer

For optimal sanding of veneer products consistently, sanders should be configured with:1. Conveyor with variable feed speed. The ability to adjust feed speed is critical to maintaining consistency when veneer sanding. Controlling the “dwell” time under the sanding platen directly affects the amount of material removed. Single and two-speed drive motors do not have enough adjustment to dial in the correct “dwell” time for each wood species or veneer type. speed of the conveyor should be between 9-12 mpm depending on the veneer type.

Sanding and Finishing

Scratching the surface

When you sand, you are installing a series of scratches on the surface of that material to flatten it out to a point where it looks pleasing to the eye, feels smooth to the touch, and accepts an even coat of finish.

5-steps to a comprehensive compressed air assessment

The U.S. Energy Department estimates that air compressors use as much as 10% of all electricity generated in the U.S., and as much as 50% of this energy is wasted. Compressed air leaks alone account for 25-30% of compressed air use. Consequently, many industrial companies are identifying ways to lower their compressed air system energy consumption. One of the most popular methods to do so is a comprehensive compressed air assessment, or “air demand analysis.” The objective of this paper is to define the five steps required in a compressed air assessment.

Pin or pinless?

The fastest way to test the moisture content of wood is to use a moisture meter. There are two main types of wood moisture meters, pin-type and pinless.

Traditional collectors vs. high-pressure collectors

Whether or not the air is clean or laden with dust, all air has mass. This means that as it moves, frictional forces slow it down. Making matters worse, friction increases as the air’s mass and speed increase. Friction is created by the air interacting with other materials, including the dust within it, the components it moves through (for example the hose, ductwork, along with other items), and the air itself.
