TECHTONGDA Line Boring Machine, 110V Portable Hole Drilling Connecting Rod Boring Machine, Processing Hole Diameter 1.4"-3.15", 1.18" x 63" Bore Bar

Heavy-Duty Construction: Built with high-strength steel, this portable line boring machine ensures long-lasting durability, high precision, and excellent wear resistance. The 5.2ft boring bar is designed for easy disassembly and convenient installation, enabling hassle-free maintenance and adaptability to various on-site conditions.  Speed Control: The hole drilling connecting rod boring machine features advanced electrode-less speed regulation for smooth feeding and processing.The feeding system can be customized to meet specific requirements, while the limit switch automatically stops the machine at the preset depth. Flexible Installation: Mount the tool holder anywhere along the boring bar for horizontal, inclined, or vertical boring. Select boring rods of varying diameters to match aperture sizes, achieving boring-lathe accuracy and surface smoothness in diverse applications. Enhanced Safety Features: Designed with operator safety in mind, the engine boring machine includes an innovative handle-mounted controller that allows users to maintain a safe distance from the work area. The control cabinet is positioned beneath the main unit, further promoting safe and efficient operation. Wide Range of Applications: This portable hole drilling machine is specially developed for on-site servicing of engineering machinery. It is ideal for small-scale pipeline inner hole and concentric span hole machining, and is widely used across various heavy equipment, including excavators, cranes, loaders, and hoists.

Product features

1 Driving of hole drilling machine.By adopting 110V AC servo motorwith characteristics of low-speed of revolution and high torque, the complete machine can realize stationary machining in superior performance.

2 No vibration in end travel and cutting process.

3 Feeding and processing can realize elect rode less speed regulation. Feeding process can be set according to demands, and processing can automatically stop after reaching the Innit switch.

4 Boring bar adopting high-strength alloy and structural st eels featured with high hardness, high accuracy, high tenacity, good abrasion resistance, etc.

5 In effective travel, the tool rest can be fixed at any position of boring bar.

6 The boring bar can be disassembled separately to make installation.

7 ELectric motor controller is equipped with immediately brake program to Avoid vibration in shut down

8 The control Cabinet is installed below the main engine to be beneficial to safety operation.
