Types of Large Lathe Machines
Big Bore Lathes
Big bore lathes, such as those offered by Kent USA (kentusa.com), are designed for heavy-duty jobs, making them ideal for industries like oil and gas. Their robust construction allows for large diameter turning and threading applications, accommodating workpieces like steel rollers and large flanges. These machines are typically available in sizes ranging from 55″ x 80″ to a colossal 100″ x 480″.
Heavy Duty Lathes
Tsinfa (www.tsinfa.com) specializes in heavy-duty lathes that are capable of processing substantial workpieces, with spindle bores and processing lengths designed to handle weights from 3 to 6 tons. These lathes are essential for industries requiring precision and durability in their machining processes.
Vertical Lathes
Vertical lathes, like those from Okuma (www.okuma.com), allow for the machining of tall workpieces. They provide precision cutting capabilities while accommodating larger components that are difficult to manipulate on traditional horizontal lathes.
CNC Lathes
CNC lathes represent the pinnacle of automation in lathe technology. These machines utilize computer numerical control (CNC) systems for precision machining. Companies like Willis Machinery (www.willismachinery.com) offer heavy-duty flat-bed CNC lathes that ensure optimal rigidity and stability for years of reliable operation.
Conventional Lathes
Conventional lathes remain popular due to their versatility and lower cost. They are widely used in various machining applications and can be found in the inventories of companies like GMC Machine Tools (www.gmcmachinetools.com) and KNUTH (www.knuth.com).
Key Features of Large Lathe Machines
Power and Capacity
Large lathes are characterized by their significant horsepower and weight capacity. For example, Kent USA’s big bore lathes can handle turning capacities exceeding 15,000 lbs. This power allows for efficient machining of large components without compromising performance.
