CNC machine for replacement parts saves foundry $500,000 in seven yr. (Case History).Replacement parts for foundry equipment can be expensive, as well as unplanned. Rather than constantly spending money replacing parts that have broken down or worn out, foundries can manufacture replacement parts on a CNC (Computerized Numerical Control) See numerical control. CNC - Collaborative Networked Communication mill that also serves other purposes in the plant. Hurco Co., Inc., Indianapolis, has designed the VM1 machining center, a CNC mill built to perform standard milling procedures for the manufacture of relacement parts for foundry equipment. The milling machine milling machine Machine tool that rotates a circular tool with numerous cutting edges arranged symmetrically about its axis, called a milling cutter. The metal workpiece is usually held in a vise clamped to a table that can move in three perpendicular directions. measures 71 x 63 x 84.5 in. (180 x 160 x 215 cm) and travels 26 x 14 x 18 in. (66 x 36 x 46 cm) on its table surface. It comes with an 8000 rpm spindle spindle: see spinning. A rotating shaft in a disk drive. In a fixed disk, the platters are attached to the spindle. In a removable disk, the spindle remains in the drive. Laptops use spindle designations to indicate the number of built-in drives. for fast throughput and a 16-station swing arm automatic tool changer Changer The name given to a clearing member that is willing to assume the opposite position of a futures contract within a larger alternative exchange, of which it also is a clearing member. that moves from tool to tool in 2.5 sec. Hamilton Foundry & Machine Go., Decatur, Indiana Decatur is a city in Adams County, Indiana, United States. The population was 9,528 at the 2000 census. The city is the county seat of Adams CountyGR6. This town is named after war hero Stephen Decatur, Jr. It was founded in 1836. , purchased a Hurco CNC Mill to manufacture its own replacement parts. The foundry recouped its investment in less than a year and achieved a net savings of $500,000 in 7 yr. The foundry's machine uses the Ultimax control system, which helps reverse engineer broken or worn parts. After parts are measured and the data is entered numerically and graphically, the system creates drawings based on the measurements. Parts can be created on the mill from bar stock, or wood tooling can be machined so the part can be cast in-house and then machined on the mill. Following are some examples of typical spare parts Spare parts, also referred to as Service Parts is a term used to indicate extra parts available and in proximity to the mechanical item, such as a automobile, boat, engine, for which they might be used. Spare parts are also called “spares. the foundry made and how much they would have cost to purchase: * a flight conveyor Conveyor A horizontal, inclined, declined, or vertical machine for moving or transporting bulk materials, packages, or objects in a path predetermined by the design of the device and having points of loading and discharge fixed or selective. chain link cost $50, but was made for $7.75, an 85% savings; * two mold-car wheels totaled $75.40, but were made for $41.55, a 45% savings; * three line rollers cost $60, but were made for $27.42, a 54% savings; * four cylinder end brackets totaled $200, but were made for $47.50, a 76% savings. In addition, once a part has been produced, the data is already stored in the system and subsequent replacement parts will be less expensive. This also allows for design improvements. Parts can be made on demand, which lowers maintenance inventory, and the mill can machine prototype or production castings in an emergency. Select No. 003 at www.moderncasting.com/info |
