3 Axis Milling   Milling is the machining process of using rotary cutters to remove material from a section of metal, wood, foam, or plastic, to structure the piece into a precise pattern. 3 Axis Milling is engaged when the cutting requires concurrent composed movement of the X, Y and Z axes. It's the least progressive of the three main axis millings available on commercial markets.
4 Axis Milling  Cutting such as this contains the above axes plus 1 rotary axis action. There are two potentials - 4 axis concurrent injection (also known as true 4th axis) or just 4th axis aarrangement where the 4th axis can relocate the section amid 3 axis processes, but does not actually rotate during the assemblation. It is one of the most popular milling choices because it permits for more comprehensive cutting than 3 axis. But, in current years, its abilities were passed by the more progressive 5 axis milling.
5 Axis Milling   During cutting, 3 Axis milling in addition to 2 rotary axis actions grant a CNC machine to maneuver a tool on 5 contrasting axes. The cutting tool has the capability to move across the X, Y, and Z axes, but pivots on A and B axes also, permitting the machine to access a workpiece from every direction achievable. With the appropriate tools secured, 5 axis milling can cut banal designs in steel, aluminum, granite, and even marble. Often times used with a CAM/CAD system package, this type of milling allows for the most sophisticated cutting capability in modern times. 
CNC Machining  CNC Machining is a process used in the manufacturing sector that involves the use of computers to operate machine tools and often uses the acronym CNC (Computer Numerical Control). Tools that can be controlled in this manner include lathes, mills, routers, and grinders. 
CNC Turning  CNC turning is an across-the-board word for the assorted versions of CNC lathe work performed by X-Cel Technologies. Depending on the assignment being performed and the equipment necessary for the project, turning may mean:

Pinch Turning – The action of using two separate tool turrets on a CNC lathe. Pinch turning allows for quick cutting and can complete rough turning and finish turning in a single pass.

Contour Turning – The action of moving a smooth extended curve on the apparatus. Contour turning demands particular bits, and a professional machinist to create an excellent curve.

Follow Turning – Any turning action implementing two separate tool turrets on the lathe. Pinch turning is a version of following turning.

Horizontal Turning – Any CNC lathe which rotates horizontally.

Vertical Turning – Any CNC lathe which rotates vertically.  

Contour Milling/Profiling  Contour milling creates a repeated curve of diverse degrees. Contour milling necessitates comprehensive expertise of complicated curriculums and equipment for the production of ultra-definitive tolerances and angles. Especially complex industrial parts and even artwork can be milled from massive blanks using contour milling.  
Deburring  A completion approach used in industrialized location and manufacturing surroundings. Many practices are in order to develop pieces of precise shape and size, and it may be welded, molded, cast, trimmed, slit or sheared. These actions often produce ragged edges or protrusions. The raised particles and shavings that materialize when metal blanks are fabricated are known as burrs, and the course by which they are eliminated is known as deburring.  
Micromachining  When the milling is performed by a movement different than that of a sharp-edged tool, like with an electron beam or lasers. This technique is implemented to manufacture mini features in parts - measured in micrometers or millimeters. The work is concluded through pulsed lasers, unloading tiny, finite chunks of energy into a material, resulting in highly precise and uniform material removal.  
Micron Tolerance   The most solid tolerances achievable, micron tolerance is the essence of efficiency. While many tasks depend upon efficiencies as compact as 1/25th the consistency of a human hair, some designs desire exactness as close as a few microns! Micron tolerances are accomplished through a process called micromachining, and require the responsibility of an accomplished machinist.  
Repeatability  The ability to routinely and progressively create components with ultra-tight tolerances. Repeatability is important when cloning replacement parts.  
Spark Erosion  Spark erosion is a contemporary machining approach with definitive benefits as a result of which its use is becoming more universal. Crucial to Wire EDM, spark erosion is the action of discarding material from a work piece with an array of briskly reappearing current charges between two electrodes. 
Swiss Lathe  A specific design of lathe providing extreme accuracy (sometimes holding tolerances as small as a few tenths of a thousandth of an inch—a few micrometers) that holds the workpiece on the Z axis using a collet and guide bushing. This is different from many lathes where the tool moves and the work piece stays stationary.
Ultra-precision Machining  High Precision in conventional machining alludes to tolerances of microns in the single-digits. Ultraprecision Machining is a mechanical machining process which is applied to macroscopic workpieces and whose accuracy has been driven to its ultimate technological limits.
Wire EDM  Electrical discharge machining (EDM), also known as spark machining, spark eroding, burning, die sinking, wire burning or wire erosion, is a manufacturing process by which a desired shape is achieved by using electrical discharges (sparks). A state-of-the-art machining process that uses electricity to cut any conductive material exactly with a thin, electrically charged wire as an electrode.
