Line Portable Boring Machine

【Parameters】 - The maximum processing hole diameter: Ф260mm(10.24inch); The minimum processing hole diameter: Ф55mm(2.17inch); Boring bar: 50*1500MM(1.97*59.06inch); The maximum processing travel: 380mm; The maximum feed depth: 2mm on one side (A3 steel); Surface roughness: Ra3.2; Deviation from circular form≤0.02mm; Rotate speed: 0-83RPM 【Motor and Handle Controller】 - The whole machine adopts 110V constant current motor with low speed and large torque, which can realize stable processing and superior performance. The motor controller is equipped with a dynamic delay braking program to avoid vibration during shutdown. After the machine is installed, the controller can be removed to control the machine and perform the drilling operation. The control cabinet is installed under the host, which is conducive to safe operation. 【4.9FT Boring Bar】 - Made from robust alloy and structural steel, our boring bar embodies high hardness, high precision, high toughness, and notable wear resistance, promising longevity and reliability. For your convenience, the boring bar can be easily disassembled and reassembled. 【Flexible Speed Regulation】 - Our machine supports stepless speed regulation for feed processing, letting you tailor the operation speed to your needs. The feed will automatically stop once it reaches the limit switch, ensuring precision and safety. 【Wide Application】- Designed primarily for processing small-scale pipeline inner hole and concentric span holes, this portable hole drilling machine is an essential tool for field service of engineering machinery. It finds versatile applications in engineering machinery, including excavator, crane, loader, and hoist.
