Not all OEMs own and operate all the equipment essential for producing their products. Very few can afford to. When it comes to machining services, many decide to contract out. This is true for such things as milling and turning. CNC contract milling is a common practice for ensuring the components they need, receive the specified shapes, holes and tight tolerances.
What Is It?
Contracting is, as the name indicates, is the hiring of an individual or a company to perform work or services for your own OEM. It is a common practice among modern manufacturing concerns. They opt to “job” or contract out in order to save time, money and labor. OEMs can then focus on what they do best while still producing quality and even specialty products. Contracting is also an excellent way an individual can ensure the production of his or her product without ever owning a manufacturing facility.
Types of Milling Equipment
Contract milling can address the needs of specific parts by many diverse companies. CNC milling equipment can fall into one of two classifications:
- Horizontal: Two of the most common examples of this type of milling machine are the Universal and Plain
- Vertical: Two specific examples of this type of milling machine are the Bed and Turret
Within these categories, millwrights can find themselves working with everything from the most simplistic machines, e.g. column milling machines, to devices that are more complex, e.g. CNC Bridgeports. Their customers also vary. They range from the automotive industry to military and defense work.
CNC Contract Milling and More
Milling is a subtractive form of manufacturing. However, those who request CNC contract milling generally ask for other services. Some of them may be additive. Many are value-added services, intended to improve the overall experience with a contractor. All require the contractor to pay close attention to the specifications while adhering to the deadlines.
