• UPC   785869978737
• PARAMETERS-The maximum processing hole diameter is Ф180mm(7.09inch). The minimum processing hole diameter: Ф45mm(1.77inch). Boring bar: 40*1500MM(1.57*59.06inch). The maximum processing travel: 380mm(14.96inch). The maximum feed depth: 2mm on one side (A3 steel). Surface roughness: Ra3.2. Deviation from circular form≤0.02mm. Rotate speed: 0-83RPM 4.9FT BORING BAR-The boring bar is made of high-strength alloy and structural steel, which has the characteristics of high hardness, high precision, high toughness and good wear resistance. The boring bar can be disassembled separately for convenient installation. MOTOR -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 delayed braking program to avoid vibration during shutdown. The control cabinet is installed under the host, which is conducive to safe operation. STEPLESS SPEED REGULATION-Stepless speed regulation can be realized for feed processing. The feeding process can be set as required, and it will stop automatically after reaching the limit switch. APPLICATION-The drilling machine is a portable processing equipment developed for on-site service of construction machinery. It is mainly used for processing inner holes of small tubes and concentric cross holes. Widely used in excavators, cranes, loaders, cranes and other construction machinery.
