A Tool as an Asset

DSC_0218The main difference between a quality saw and a less than perfect saw lies not in the outward appearance but rather in what’s below the surface. And with the ever increasing amount of different saw blades, the choices are aplenty and become more challenging.

Top Quality tools offer a high degree of technical sophistication. There are some important details that differentiate the better tools from those of lesser quality.

The quality of the materials, the technology, the workmanship and the support provided by the tool manufacturer are the factors which eventually determine whether the user will be able to perform high quality cuts with a saw blade and also how long the blade will last.

Sales figures for low-cost producers show that purchase decisions are often price-driven. Other factors, such as product quality and safety, are often merely an afterthought or only come in as a secondary consideration.

Those who make purchasing decisions based on price alone though, generally wind up paying more in the end. When one considers that the money spent on tools is only a small percentage of the total tool cost but the tool has a decisive influence on the quality of the workpiece, a high quality tool should be the right choice.

National “Get Woodworking Week!”

DSC_0222

It’s National Get Woodworking Week!

DSC_0227

Woodworking is a hobby and/or profession that is fun and interesting. It not only challenges creative skills but also analytical skills. On top of that, it also leaves one with a feeling of satisfaction upon finishing a project and being able to see a completed product.

DSC_0219

Get Woodworking Week started as an idea by Tom from Tom’s Workbench. In order to preserve traditional woodworking and to make sure the craft of woodworking doesn’t get lost over time, he and a few other passionate woodworkers decided to initiate National Get Woodworking week.

Considering that the trend in the furniture industry seems to develop away from pieces that are build to last and more towards pieces out of MDF or particle board, his efforts are commendable.

Upon realizing that woodworking isn’t taught in schools nearly as frequently anymore as it used to, Tom and his fellow woodworking friends decided that it was time to start National Get Woodworking week in order to inspire those new to woodworking to get more involved, inspired and motivated.

Diamond vs. Carbide Tooling Cost Comparison

DSC_0041

Diamond Router Bits

It is well-known that Polycrystalline Diamond (PCD) tooling delivers high performances in cutting applications while also significantly while reducing a company’s overall tooling costs.  Under the right conditions and with the proper maintenance, great cost savings can be achieved. The first tool life can yield savings of up to 30 -50% in comparison to carbide tools or inserts. And subsequent sharpenings will further increase the savings when compared to a carbide tool or insert.

The Example Cost Comparison (per Linear Foot Machined):

The calculation quite accurately illustrates, that although at first look Diamond tools seem to be a costly investment, it is an investment that pays off rather quickly and costs only a fifth of what equivalent Carbide tools would cost.

It may not be necessary to buy Diamond Tools for everyone and every company, but especially those who need their tools to last as long as possible and would like to get as much use out of them as possible, will find that investing in diamond tools is more than cost-effective.  The best applications for diamond tools are those machining  abrasive materials and doing high volume of the same cut. We are now offering select tooling online.

Staying Sharp on Saw Blades

To ensure saw blades meet optimal cut expectancy and last as long as possible, a few key factors are essential.

First and foremost it’s important that the saw blade selection is based on the material that will be cut. Choosing the proper blade for the material will not only optimize the saw blade’s longevity, but also increase its performance. Many shops with cutting needs for varying materials use an “all-around” blade to perform cuts on a number of different materials. Although this approach may seem most cost efficient, it decreases the tool’s life and in most cases fails to deliver cutting results and a high quality cut.

Just as important to optimizing blade performance is having a high quality, sturdy, and solid-built saw to begin with. Saving money on a lower quality saw may appear to be beneficial in the short run, but saving money on cheaper blades  and saws will trickle down to increased costs for sharpening, more frequent needs for blade replacement and lower cut quality in the long run along with a higher cost per linear foot cut.

The tooth shape is essential when it comes to guaranteeing the optimal blade life. Any tooth shape may work for a period of time and deliver satisfying results in the beginning but, again, in the long run an improper tooth shape will deliver poor cutting results and increase your overall cost of tooling. For example, an Alternate top bevel may deliver great results for cutting wood across the grain, but using it on particle board will lead the edges to become dull rather quickly leading to a shorter time duration between sharpening and replacement. This happens  because the alternate top bevel teeth break down more rapidly when confronted with resins and silica particles in particle board.

In order to make sure the arbor and saw collars are free of debris, they should be cleaned properly as resin and wood dust can damage  the collars and lead to unintended results which may include less accurate cuts and quicker dulling of the blade. Cleaning blades can be done quite effectively with Simple Green, which is non-caustic and not damaging to the blade or your lungs. Scraping the blade or its teeth is not advisable. Blades can also be soaked for a while. For example taking the blade off the machine during lunch time and soaking it in a solution and then brushing it off will assure that no dust particles or other residue is on the blade during thee cutting process.  Soaking can also be done overnight in kerosene and then the blade should be brushed off with a soft brush, like a tooth brush. When employing this solution remember that the solvents are extremely flammable, so take appropriate precautions. Machining operators will notice that this will increase the blades life significantly and in most cases lead to the blade lasting about three to four times as long. Blade maintenance is particularly important if the material has pits or content in it as some wood species do; or if there is glue in the material.

Furthermore it is important that the saw is properly aligned as saws out of alignment can be dangerous and generate heat that can lead to wear on the saw blade.

A quality carbide tipped saw blade should be able do be sharpened at least 12 times. To reach that number, overrunning the saw blade past it’s ideal sharpening time needs to be avoided.
