  • Sawing Basics V63WCWO3 Operator Variables That Aid Sawing Performance When Making Blade Recommendations, There Are a Few Questions We Need to Answer
    Sawing Basics V63WCWO3 Operator Variables That Aid Sawing Performance When making blade recommendations, there are a few questions we need to answer: • Which blade do we use? • Which tooth pitch do we use? • Which blade speed should we use? • Which feed rate should we use? • What is the relationship between feed & speed? • Why do we need a cutting fluid? • Why do we need blade break‐in? Which blade do we use? Items that influence selection • Machine type—Low cost, low performance machines will not allow a band saw blade to function optimally. • For low performance machines, select blades that can withstand higher shock, chatter, or • The better the feed system on a machine, the higher performance blade that can be used effectively. • Production Rate– The more cuts per hour or the longer the run time the higher the performance blades will be needed. • Cost Per Cut‐To lower the cost per cut, move to a higher performance blade. What Blade Do We Use? Items That Influence Selection Material Machinability‐ Machinability is generally rated from 0 to 100% (SAE1112, rated at 100%, is considered free cutting) • Alloy type (Carbon vs. Nickel‐based, etc.), hardness (Heat‐Treated or aged), and material shape all affect material machinability • The higher the alloy, the lower the machinability rating • The higher the material hardness, the lower the machinability • Complex material shapes will lower the machinability rating due to increase shock Abrasiveness‐ Abrasive material or coatings will reduce the life of a band saw blade‐ consider carbide tipped

  • Antares, Inc. Fact Sheets Rotary Engraving © 2011 - Antares, Inc
    Antares, Inc. Fact Sheets Rotary Engraving © 2011 - Antares, Inc. Description Rotary engraving is the term used to describe engraving done with a rotating cutting tool in a motorized spindle. The tool, or cutter, cuts into the surface of the material to a predetermined depth and produces a groove of the same shape and dimension of the cutter. Rotary engraving can be performed on a wide variety of materials with plastic, brass, and aluminum being the most common in the awards industry. Rotary engraving can be done using the simplest pantographs to the most complex computerized engrav- ing machines. The principles are the same on all. On a pantograph, the operator lowers the cutter into the material and then forms the character by tracing a master (copy type, template, etc.). On a computerized machine, the cutter spindle (Z-axis) is lowered mechanically and then is moved laterally (X-axis / Y-axis) by stepper motors to form the characters. Engraving Cutters The tools used for rotary engraving are generally referred to as “cutters.” Cutters are manufactured from different materials and are produced in a variety of configurations specific for certain applications and materi- als. Most engraving cutters are “half-round” tools which means the blank is split or halved on center produc- ing a “single-lip” tool which is one of having only one cutting edge. This configuration affords a significant amount of clearance and allows the tool to run at relatively high speeds to maximize material removal and produce good finishes. Some cutters are also made as “quarter-round” tools which allow even greater clear- ance, but they are inherently weaker and are recommended for specific applications.

  • TIVAR Fabrication & Machining
    TIVAR Fabrication & Machining TIVAR can be efficiently machined using conventional Turning (cont.) machine tools and woodworking machinery. It is often necessary to run at reduced RPMs to enable the operator to keep chips clear of the machine. Care must Cutting tools should have high rake angles and sufficient be taken: it is easy to get hands caught in the machinery chip clearance to prevent clogging. If the above criteria are and debris. met, cutting speeds of up to 5,000 surface feet per minute are practical. Feed rates should be high, so that minimum Milling time is allowed for the cutting tool to heat the material by Carbide cutters designed for machining aluminum give friction. the best results. Conventional high-speed steel end mills and Very high surface finishes can be obtained by using cutters designed for machining steel can be used, but they proper cutting tools. Attempts to improve poor finishes by do not have sufficient rake angle or chip clearance for filling or sanding usually result in worsening the appearance. efficient stock removal. Cutting fluids should not be necessary, but a blast of Router bits work well for slotting and light milling. For compressed air will sometimes aid in chip removal. cutting deep slots and T-slots, it is essential that compressed air be used to blow chips away from the cutter.
