Specification Brand : TECHTONGDA BulletPoint1 : 【Good Performance】-The maximum processing hole diameter: Ф180mm. The minimum processing hole diameter: Ф45mm. 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. 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. BulletPoint3 : 【Boring Bar】-The boring bar is made of high-strength alloy steel and structural steel, which is characterized by high hardness, high precision, strong toughness and good wear resistance. And it can be disassembled individually for easy installation. BulletPoint4 : 【Use Safety】-The control cabinet is installed below the main engine to be beneficial to safety operation. Electric motor controller is equipped with dynamic delay brake program to avoid vibration in shutdown. BulletPoint5 : 【Attentions】-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.
