The Engravers' Bible

EquipmentIn this chapter we will discuss some of the more important pieces of equipment that you need to be aware of if you are starting a new engraving operation or looking to expand an existing one. Which Engraving System Is Right For Me?Presented below in greater detail are several recognized markets, types of objects generally engraved, and equipment required. Due to the crossover of markets and range of products, any given shop may do most or all of the items listed. Armed with this knowledge, making a decision about the appropriate engraving machine is much easier. Gift/NoveltyFor flat or limited concave/convex surfaces, any manual or computerized engraver will do. When working with odd-shaped objects such as baby gifts (i.e., rattles, banks, bronze baby shoes), a deep workholding vise is necessary. The biggest challenge is the ability to fixture the object securely for engraving. The slightest movement will result in poor letter quality and may even force you to scrap the item. Trophy/AwardThis is by far the single largest user group of production-oriented engraving equipment. Most "flatbed" (non-vise type work area) computerized engravers will do the job. The key element to deciding on the right machine for your needs is your volume and the demands of repetitive work. A 500-piece trophy order requires a software program of sufficient capability to aid the user in both set-up and data entry of the 500 unique names of the award recipients. Industrial/InstitutionalMost industrial work is high-production and heavy-duty in nature. You can understand the need for a robust and rugged machine that will take the continuous pounding of repetitive work. Many of these machines are customized to fit in a production line environment. They may be outfitted with extra features or accessories for cutting in exotic or difficult-to-cut materials such as stainless steel. When searching for this kind of equipment, care must be taken to select a machine that has the rigidity that will result in good letter or cutting quality. Mass equals rigidity in engraving, and a heavy-duty machine is usually constructed of castings, steel, and heavy extruded aluminum parts. You will also find that larger than average motors are used to drive the heavier mechanisms and spindles. MarkingThe marking industry may require highly specialized or modified engraving equipment due to the shape or complexity of the engraved item. Many applications include custom fixtures for items such as notary seals. Again, a versatile machine offers more flexibility, and the ability to handle repetitive work is important. SignageFor those who wish to offer simple, general signage or ADA (American's with Disabilities Act) compliant signage, most engraving systems will do. For larger signs and those made of wood or more exotic materials such as thick foams, etc., a large bed engraver or a router system is called for. Routers offer several advantages. Clearance between the cutting head and the work surface allows for thicker materials to be cut. They are designed to have the rigidity to support a larger cutting motor or commercial routers. Several advantages will be discussed later in greater detail. |
