Standard Band Saws and Circular Blade Billet Saws for Automatic Sawing in Unattended Environments
Selecting the Right Material Handling System for Your Industrial Sawing Process
Investing in the right material handling system for your sawing application can improve safety and productivity of your overall sawing processes.
Carbide-Tipped Saw Blades Offer Flexibility & Just-In-Time Production
Carbide-tipped blades increase tool life, provide faster cutting rates, and decrease production costs
Why Flood Cooling of Carbide Teeth Won't Work on Carbide Cold Saws
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.
Why Minimum Quantity Lubrication is Used in Cold Sawing
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.
Key Calculations for Maximizing Tool Life in Carbide Saws
Torsional vibrations are hard to measure because of the rotating elements (gears, shafts) that are inside a closed gear case and not easily accessible. However, knowing the exciting torque, passing through the gear train and the gear data, critical vibrations such as resonance can be calculated and analyzed. 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
There are several proven methods to minimize backlash and reduce vibration during the carbide sawing cycle. The most damaging aspect of the sawing process is the entering and exiting of the circular blade in and out of the material. The "hammering" effect at the beginning and ending of the saw process can severely damage the carbide teeth of the saw blade. Saw machine designers have created several devices of varying complexity and costs to minimize these problems.
These 13 Issues Will Destroy High Production Carbide Tipped Circular Saw Blades
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 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
This third and final article in the current series describes how to best minimize the damaging effects of vibrations and resonance with stabilizers and dampers. Even with a well-designed carbide saw, blade vibrations still occur. That is because it is nearly impossible to take into account every possible cause of vibration. 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
In this second of three articles, we focus on the destructive force behind carbide saw breakdowns with an in-depth look at resonance. Do not 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
Vibration is harmful in any sawing machine, but in high production saws with hard and brittle carbide-tipped blades, it can be catastrophic. Reducing vibration is the main focus for machine designers, because vibration dramatically affects the tool life of the saw blade and increases 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
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.
Torsional Vibrations in Carbide Sawing
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.
