Cutting Fluid Effects in Machining


The primary functions of cutting fluids in machining are :

  • Lubricating the cutting process primarily at low cutting speeds
  • Cooling the workpiece primarily at high cutting speeds
  • Flushing chips away from the cutting zone
Secondary functions include:
  • Corossion protection of the machined surface
  • enabling part handling by cooling the hot surface
Process effects of using cutting fluids in machining include:
  • Longer Tool Life
  • Reduced Thermal Deformation of Workpiece
  • Better Surface Finish (in some applications)
  • Ease of Chip and Swarf handling

Parts of Vertical Milling Machine

Image
Parts of Vertical Milling Machine The vertical knee mill is the most common milling machine found in machine shops today. Therefore it will be used as an example to describe the general parts of all mills. Head                The head (drive) is that part of the drive system that transforms electrical power from a motor to mechanical power in the spindle. The drive system also allows the machinist to change the speed of the spindle (RPM) and therefore the cutting tool. The quill moves vertically in the head and contains the spindle in which cutting tools are installed. Column                The column is the most important part which is mounted on the base and acts as a support and holding device for all the other parts of a milling machine. It acts as a support for table and all feed mechanisms. The column should be rigid enough to sust...

Tool Holding Devices in Drill Machine

Image
Tool-Holding Devices: Drill press spindle provides means of holding and driving cutting tool.End may be tapered or threaded for mounting drill chuck. Most common devices are used in Drill presses:       Drill chucks       Drill sleeves        Drill sockets Drill Chucks: Most common devices used for holding straight-shank cutting tools. Most contain three jaws that move simultaneously when outer sleeve turned. Hold straight shank of cutting tool securely. Two common types               Key   Keyless     Drill sleeves:                        Used to adapt cutting tool shank to machine spindle if taper on tool is smaller than tapered hole in spindle   Drill sockets: ...

Study of major parts of Upright Drill Machine

Image
  Base:              The base is that part of a machine on which the column is mounted.   Column: The column is the most important part which is mounted on the base and acts as a support and holding device for all the other parts of an upright drilling machine. It acts as a support for table and all feed mechanisms. Table:           Table is the part on which the work piece is mounted. This is held up by fixing it to a column. A table can have rectangular geometry or circular in shape. Slots are provided on the table for holding the work piece very effectively. Three types of movements of the table are provided so as to achieve the centering very easily. The three movements incorporated in the table are   ·    Vertical adjustment ·    Radial adjustment around the column   ·   Circular adjustment about its own ...
