Specification Brand : ZNNRKMYO BulletPoint1 : By driving method: Hand tapping is convenient for manual operation and suitable for small batches, situations with low precision requirements, or situations lacking mechanical power; Machine taps can be adapted to machine tools to achieve large-scale thread machining with automation, high precision, and high efficiency. BulletPoint2 : According to the processing method: the cutting tap removes material through the cutting edge to form threads, which is widely used; Squeezing taps rely on plastic deformation of materials through squeezing to form threads. The processed threads have high strength and good surface quality, making them suitable for materials with good ductility. BulletPoint3 : According to the shape of the chip groove: the straight groove tap is easy to manufacture, has strong universality, and is suitable for processing various materials and through holes; Spiral groove tap has smooth chip removal, especially suitable for blind hole processing, which can effectively avoid chip blockage. BulletPoint4 : Before use: Check if the tap is intact and if there are any defects such as wear or cracks; Select the appropriate cutting fluid based on the workpiece material and tap type to reduce friction, improve cooling and chip removal efficiency. BulletPoint5 : In use: Control cutting speed and feed rate to avoid overloading causing tap breakage; Keep the tap perpendicular to the workpiece to prevent thread deviation. When manually tapping, every 1/2-1 rotation should be reversed by 1/2 rotation to facilitate chip breaking and removal. BulletPoint6 : After use: Clean the chips and oil stains on the tap in a timely manner, apply rust inhibitor, store it properly, and extend its service life.
