What is reaming?
Reaming is a machining process used to process holes or holes in a workpiece, usually to enlarge or precisely machine the inner diameter of an existing hole. This process typically involves using a special tool, such as a reamer or reamer bar, that is rotated and advanced through the workpiece to remove material and form the inside walls of the hole. Reaming operations are suitable for a variety of different types of workpieces and materials, including metals, plastics and composites.
Here is the basic working principle of reaming:
1. Workpiece clamping: First, the workpiece is installed on the workbench or in a fixture to ensure that the workpiece is fixed and will not move. Clamping systems often come in a variety of designs to accommodate workpieces of different shapes and sizes.
2. Select a reamer: Choose a suitable reamer based on the required hole diameter and depth. Reamers usually have multiple cutting edges and are used to remove interior wall material.
3. Set cutting parameters: The operator needs to set the cutting parameters of the reamer or reamer, including cutting speed, feed speed, cutting depth and coolant usage. These parameters influence the quality and efficiency of the cutting process.
4. Start reaming: Once the positions and parameters of the reamer and workpiece are set, the reamer or reamer machine starts, and the reamer begins to rotate and advance into the workpiece, gradually removing the inner wall material and forming the inner diameter of the hole.
5. Cooling and lubrication: During the cutting process, coolant or cutting lubricant is usually used to lower the temperature, reduce wear and flush away chips.
6. Monitor and measure: Operators typically monitor the reaming process on a regular basis and use measuring tools, such as micrometers or bore micrometers, to ensure the bore's bore size and quality meet specifications.
7. Completion of reaming: Once the required hole inner diameter size and quality are achieved, the reaming operation stops and the workpiece can be removed from the workbench or fixture and prepared for further processing or use.
Reaming is often used to manufacture holes that require high-precision inner diameter dimensions, such as bearing seats, transmission holes, valve seats, threaded holes, etc. It has wide applications in manufacturing, machining, aerospace and other fields.
