Specification Brand : TECHTONGDA BulletPoint1 : High Quality Material: Boring bar adopting high-strength alloy and structural steel is featured with high hardness, high accuracy, high tenacity, good abrasion resistance, etc. The boring bar can be disassembled separately to make installation convenient. The control cabinet is installed below the main engine to be beneficial to safety operation. BulletPoint10 : BulletPoint2 : Electrodeless Speed Regulation: Feeding and processing can realize electrodeless speed regulation. Feeding process can be set according to demands, and processing can automatically stop after reaching the limit switch. Electric motor controller is equipped with dynamic delay brake program to avoid vibration in shutdown. BulletPoint3 : Continuous Current Motor: By adopting 110V continuous current motor with characteristics of low-speed of revolution and high torque, the complete machine can realize stationary machining in superior performance. BulletPoint4 : Pay Attention: This portable line boring machine is installed by fixed clamping, and uses different tool rest according to different diameter ranges. Please confirm the diameter of processing hole before use to select the appropriate tool rest. BulletPoint5 : Widely Application: Hole drilling machine for engineering machinery is a portable processing equipment developed for field service of engineering machinery, which is mainly used in processing of small-scale pipeline inner hole and concentric span hole, and widely applied in engineering machinery, including excavator, crane, loader, and hoist.
