Bridgeport Milling Machines
Almost any industrial operation requires milling machinery; the ubiquity of these machines means that every day there's someone looking to buy or sell a milling machine.
What does a milling machine do that makes it so essential in manufacturing? Simply put, a milling machine is a tool that achieves the shaping of a solid (made of metal, in many cases, though other materials such as wood can be milled as well). A cutter or endmill is rotated around the workpiece on a stable but movable table. Milling machines may be manually operated but more often today they are CNC machines.
Mills can be categorized: there are, broadly speaking, vertical mills and horizontal mills. In the case of the vertical mills, they can be broken down into two smaller groups: bedmills and turret mills. Turret mills tend to be smaller than bedmills and can offer greater flexibility when it comes to manipulating a workpiece. There is also an even smaller machine called a mill-drill. Horizontal mills are excellent when a workpiece needs to be milled at relatively shallow angles, a function at which vertical mills may not excel.
GreasyMachines.com, being based in Connecticut, has a particular interest in the history of milling machinery because the best-known mill manufacturer for decades has been Bridgeport, a company that was founded in Bridgeport, Connecticut. The company, known for turret mills, is now based in Elmira, New York, but it remains a standard in the industry. Bridgeport mills are highly sought-after, valuable machines, and we are always happy when someone contacts us to discuss a Bridgeport mill.
The fact is that milling equipment is a major investment. Many people find that buying a used milling machine is the sensible thing to do. Because a used milling machine can serve just as well as a very expensive new machine, it makes sense to research the market for used machines. As long as a mill is well maintained, and has been operated with proper lubrication, you should be able to find an ideal used mill without too much agony. Whether your company has a specific milling machine in mind or if you're simply looking for certain specs and are not as concerned with the manufacturer, GreasyMachines.com has the inventory and the skills to provide your company with the equipment it needs.
