Why Flood Cooling of Carbide Teeth Won't Work on Carbide Cold Saws

Posted by Willy Goellner

The carbide tips of a circular saw blade crack under extreme temperature changes, demonstrating why a flush coolant system won’t work on carbide cold saws.

When to Use Circular Saw Machines vs. Band Saw Machines

Posted by Willy Goellner

Circular carbide saw machines and band saw machines both have their place on a shop floor. Your needs and overall goals will determine if a circular saw machine or a band saw machine is best for your operation.

Automating Manufacturing with Rail Sawing and Drilling Processes

Posted by Chris Rindels

Combination machines with material handling streamlines rail sawing and drilling processes -- providing more throughput, increased quality and efficiency, and improved viability.

Why Minimum Quantity Lubrication is Used in Cold Sawing

Posted by Willy Goellner

Minimum Quantity Lubrication (MQL) is used in cold sawing to prevent heat build-up through friction reduction to keep both the material and the blade cool during the sawing process.

Why is a Circular Metal Saw Called a Cold Saw?

Posted by Willy Goellner

Circular cold saws allow both the material and blade to remain cool during the sawing process by transferring the generated heat to the chips.

How to Cut Cost Using Different Types of Carbide-Tipped Circular Saw Blades

Posted by Willy Goellner

Carbide-tipped circular saw blades are offered in three versions with different cost structures: Re-grindable (Resharpenable) Carbide-Tipped Saw Blades, One Way (Throwaway) Blades, and Replaceable Carbide Tip Circular Saw Blades.

Do You Really Know the Cost of Your Carbide Billet Saw?

Posted by Willy Goellner

When you have to cut a lot of alloy steel, cutting speed is an obvious issue - but are you getting the saw for a good price? We'll explain how shock load and operator error can affect the total cost of your carbide billet saw.

What Circular Saw Blade Tooth Geometry is Best for Sawing Steel Billets?

Posted by Willy Goellner

The heat from the cutting process, especially using negative cutting angles when cutting steel, transfers to the chip, causing it to expand and jam in the slot. This can be prevented by splitting the chip. There are two common tooth geometries developed to split the chip: “Triple Chip” and “Notch Grind.”

Key Calculations for Maximizing Tool Life in Carbide Saws

Theoretical analyzation, calculation, and practical identification.. The calculations and theoretical analysis shown in this article show that much can be theoretically analyzed, where practical limitations exist.

Innovative Devices to Maximize a Carbide Saw's Blade Life

Posted by Willy Goellner

Proven methods for minimizing backlash and reducing vibration during the carbide sawing cycle, reduce the cost of carbide sawing.

These 13 Issues Will Destroy High Production Carbide Tipped Circular Saw Blades

Posted by Willy Goellner

Achieve the highest productivity in metal sawing by taking care of your carbide tips. Production managers and manufacturing engineers choose circular carbide saw systems when they need the sawing method with the highest productivity. Without a doubt, circular sawblades equipped with carbide teeth are the most productive tool for high production metal sawing, but if you are replacing your blades too often, high productivity will quickly be negated by the high cost of tooling and the lengthy changeover time.

Minimizing the Damaging Effect of Vibration and Resonance with Stabilizers and Dampers

Posted by Willy Goellner

This third and final article in the current series focuses on how best to minimize the damaging effects of vibrations and resonance with stabilizers and dampers. Even with a well-designed carbide saw, blade vibrations will still occur. That is because it is nearly impossible to take into account every possible cause of vibrations. Understanding stabilizing and damping best practices is the key to minimizing the inevitable vibrations that occur during the sawing process.

Resonance – The Destructive Force Behind Carbide Saw Breakdowns

Posted by Willy Goellner

In this second of three articles, we are focusing on the destructive force behind carbide saw breakdowns with an in-depth look at resonance. Don't let resonance destroy your sawing machine and ruin efficiency within your shop. Learn how to test resonance and prevent a catastrophic outcome.

Effect and Prevention of Vibration in Carbide Sawing

Posted by Willy Goellner

Vibration is harmful in any sawing machine, but in high production saws with hard, and brittle, carbide tipped blades, it can be absolutely catastrophic. Reducing vibration is the main focus for machine designers, because vibration dramatically reduces the effectiveness and tool life of the saw blade and will increase the overall cost-per-cut. This article – which is first of a three-part series – focuses on the damaging effect and prevention of vibration in carbide sawing.

Measuring Compliance - The Weakness in Your Carbide Saw

Posted by Willy Goellner

Compliance is defined as the measure of the ability of a mechanical system to respond to an applied vibrating force, expressed as the reciprocal of the system stiffness. In short, it measures the weakness of the system. In a carbide saw, the most critical component subject to torsional and lateral vibration of the saw blade, is the gearbox, commonly called the head. When the blade tooth first contacts…

Torsional Vibrations in Carbide Sawing

Posted by Willy Goellner

Torsional vibration in carbide saws has the most damaging effect on the tool life of carbide tipped circular saw blades. It is also influenced by the blade diameter, the quality of the saw blades, the spindle gear diameter, the compliance of the gear train in the saw head and feed system, and the stiffness of the fixture and machine structure. The saw blade also must be rigidly clamped to the drive…

The History of Carbide Sawing

Posted by Willy Goellner

In 1926, Krupp, a German company, developed carbide, a very hard mixture of sintered carbides of various heavy metals, especially tungsten carbide, used for cutting edges and dies. This…
