CNC mill-turn machine, or CNC turning machines, are machine tools which rotate the work piece at a repetitive spinning motion to perform different machining tasks, including drilling, cutting, deformation, and molding. These machines can also be used for other tasks such as drilling titanium and stainless steel and joining the two or making various other precision parts. While these CNC machining centers are similar in nature and function, there are some major differences between them. Each machine operates with a unique program, which is designed and controlled by the operator. They all have the ability to make precise cuts, but each of them differs in their operating environment.
CNC vertical mill turn machines are primarily used for horizontal milling operations which include rotating and cutting work pieces. This is different from the CNC rotary and vertical machining centers, which are designed exclusively for vertical applications. CNC turning machines can also work in the reverse, which means they can perform milling operations in a horizontal manner as well.
CNC milling machines are equipped with a variety of computer software to support all the operations. This includes material planning, material handling, and machine simulation. Computer generated toolpaths give the operator a virtual image of what the finished product should look like. The toolpaths show the shortest path from any set of machine tools to their intended destinations. They can also be programmed for different operation sequences and for varying speeds.
Computer generated toolpaths are the foundation of CNC machining operation. They allow operators to precisely control the movements of the machine tools while staying within a defined machine room or work area. The toolpath allows the operator to program milling processes that work best with the existing tools in the shop. The toolpaths also define where machines will be located during any single operation.
A popular feature found in many CNC milling machines is the turret. Turret operations are used to supply the operator with a variety of options for creating different sized parts. The most common type of turret is the half-track, but other types of turbines exist such as a full-track or a cross-track. The most common function of the turret is to support rotating parts such as rollers and spindles.
Centering and alignment are two more important machining centers. Centering operations enable the operator to center work pieces in the area. This is done by drawing the new work piece into the machine tool and then aligning it along the spindle axis. Alignment happens before the new piece is permanently mounted to the spindle axis. This feature prevents machine tool slop from affecting all of the work pieces in operation.
