Broaching is a machining process with a special designed multi point cutting tool called broach. This process is widely used in automobile industries for machining various holes, key ways, gears etc. Broaching operation involves linear motion of tool about the work piece. This movement of tool removes material from work piece and provides a desired shape.
Milling is done using a cylindrical milling tool mounted in a milling tool holder that is then mounted in the tool spindle on the machine. End Mills End mills are the most common milling cutters. End mills are available in a wide variety of lengths, diameters, and types. A square end mill is used for most general milling applications.
Spud the Well: After the rig has been inspected and all of the systems tested the well can be Spudded.Spudding a Well refers to starting the rotary drilling operations for that well.; Drill Down to the Surface Casing Depth: The first section of the well to be drilled is the section that goes down to the pre-determined surface casing depth (Casing Point).
However, the operation can also be performed by turning, tapping, or milling machines. CNC Milling Equipment. Milling employs rotating multi-point cutting tools to shape the workpiece. Milling tools are either horizontally or vertically oriented and include end mills, helical mills, and chamfer mills.
Define Lapping and How it works: Loose Abrasive Process- (LAP) Lapping Involves the Use of Abrasive Particles to Modify the Work-Pieces. The Abrasive Particles are Mixed with a Water-Base or Oil Base Liquid. The Combined Abrasive and Liquid are Called a "Slurry", this is a Liquid Cutting Tool. The Slurry is Placed on a Rotating Motorized ...
