Portable Machine Tools

 Our boring machines are primarily designed for the on-site boring, reaming, and integrated bore-welding of various shaft bores, pin holes, flange faces, and bearing seats. Featuring a compact structure and rapid clamping capabilities, they enable high-precision machining of concentric bores and end faces. These machines are widely utilized in the repair and restoration of shaft bores within construction machinery, port equipment, and mining machinery. The boring machine series offers various bore diameter models, including the 40, 60, 90, and 110 series, covering a comprehensive range of on-site core maintenance requirements, from compact to heavy-duty applications. Representing an ideal choice for the bore repair of excavators and heavy machinery, these units are sold as portable line boring machines, offering both precise machining capabilities and exceptional convenience for on-site operations.

 The primary function of a flange facing machine is to restore deformed, rusted, or worn flanges to a flat, leak-proof condition; moreover, this machine is capable of performing machining operations directly on-site. At Lerford, we offer a comprehensive range of flange facing machine models-ranging from manual hand-cranked units to heavy-duty and portable systems-allowing you to select the specific type that best suits your individual requirements. All models of our flange facing machines are designed to deliver precise surface finishes and restoration for industrial flanges across various sectors, including construction, oil and gas, and marine applications.

Portable Machine Tools: Milling Machines. A milling machine is a portable tool that utilizes a milling cutter to machine workpieces; it is primarily used for operations such as milling flat surfaces, slots, steps, keyways, and contoured surfaces. Our company offers a comprehensive range of portable milling machines, specifically designed for industrial on-site maintenance operations:

XDLWX2000 (CNC Thread Milling), XDDBX1000 (Single-Arm Portable Milling), and XDLMX1000 (Gantry-Type Heavy-Duty Milling)-three models of portable on-site machining equipment designed for in-situ operations without the need for disassembly. Ideal for the high-precision repair of heavy machinery components, these units feature simple operation, flexible maneuverability, and are ready for immediate use.

 We offer a comprehensive range of on-site repair equipment specifically designed for the maintenance of bores and shaft-type components. Our automated welding machines enable precise bore welding, thereby allowing for the efficient restoration of worn bore diameters. For shaft repairs, our XDZ300 and XDZ500 models serve as reliable, portable shaft-end machining units, functioning effectively as portable shaft lathes that restore shafts to their original dimensions without the need for component disassembly. Furthermore, we provide complementary bushing presses to facilitate the complete removal and reassembly of components; this makes our equipment the ideal choice for maintenance operations involving heavy machinery, construction equipment, and various industrial field applications.
