Specification Brand : HQHAOTWU BulletPoint1 : WIDE PROCESSING RANGE- The boring machine can process the size of 45-160mm and is especially suitable for processing holes and hole series with high requirements for the hole diameters, the sizes and the positional accuracy BulletPoint2 : HIGH ERROR CORRECTION ABILITY- The boring machine has high error correction ability and can correct the axial deviation error of the original hole through multiple feeding so that the high positional accuracy between the bored hole and the positioning surface can be kept BulletPoint3 : MANEUVERABILITY AND FLEXIBILITY- The boring machine can be used on boring lathes, turning lathes, milling machines and other machine tools, has the advantages of flexibility and maneuverability and is widely used in production BulletPoint4 : STRONG SECURITY PERFORMANCE- The hole drilling machine is with a portable handle which improves safety effectively. There is a magnet on the back of the control handle, which can be attracted to the mechanical surface when not in use, making it easy to store BulletPoint5 : WIDE APPLICATION- Portable circular seam automatic welding machine is specially designed for on-site construction, with small size, light weight and good welding quality. It has low requirements on the use environment and space, and is easy to carry. It is widely used in repair welding of round holes such as pin holes and bearing holes of large equipment and engineering machinery. It is an essential tool for industrial and mining enterprises and engineering site maintenance ExternallyAssignedProductIdentifier1 : 0198462667326 ExternallyAssignedProductIdentifier2 : 198462667326 ItemName : HQHAOTWU 110V Hole Drilling Machine Bore Diameter 1.78"-6.3" with 4.92ft Boring Bar 5.25ft Boring Bar and Control Handle Portable Circular Seam Automatic Welding Machine for Engineering Machinery ItemTypeKeyword : boring-bars Manufacturer : HQHAOTWU NumberOfItems : 1 PartNumber : DX022804 and 022734 ProductDescription : Hole Drilling Machine for Engineering Machinery(110V, LT-40-2. 022804) & Portable Circular Seam Automatic Welding Machine(022734) Parameters of the Hole Drilling Machine(022804): The maximum processing hole diameter: 160mm The minimum processing hole diameter: 45mm The maximum processing travel: 300mm The maximum feed depth: 3mm on one side (A3steel) Surface roughness: Ra3.2 Deviation from circular form<0.02mm voltage:110V60Hz power:1500W Boring bar size: 160 cm, diameter 40 mm Parameters of the Circular Seam Automatic Welding Machine(022734): Working voltage: AC 110v/60hz Maximum power: 200W Machine weight: 11KG Machine size: L 400 * W 210 * H 290 Welding rod length: 116.5CM Spindle speed: stepless adjustment 0--15r/min Welding range: Φ55-150 mm Axial stroke: 255mm Wire diameter: Φ1.0 is recommended Ambient temperature: -10℃~+40℃.
