HR-30

The Kingston HR-30 Precision Lathe is a heavy-duty manual engine lathe designed for maximum stability, accuracy, and high torque cutting. This machine has been an industry leader for decades, earning its reputation as a reliable workhorse in machine shops. The massive and heavily ribbed 22-inch wide bed casting ensures exceptional rigidity and accuracy even during the most demanding heavy-duty applications. At its core is a robust headstock with a hardened and ground main spindle featuring a large 4.09-inch bore and D1-11 Camlock nose supported by a three-point bearing system for superior strength. Operators benefit from the increased control provided by 16 spindle speeds ranging from 8 to 800 revolutions per minute as standard. The totally enclosed gearbox features hardened and ground gears and shafts, providing a wide range of threading capabilities, including inch and metric module and diametral pitch, by simply changing levers. Standard equipment includes a powerful 20 HP main drive motor, a 4-way rapid traverse two-speed drive tailstock quill, a coolant system with pump and piping, and a pull drawer chip pan for efficient operation. With a 30-inch swing over the bed and lengths available up to 320 inches between centers, the HR-30 offers the capacity and precision required for challenging machining tasks.
