The most frequently used CNC machining service for metalwork is CNC milling machine services. Milling is a high-demand service for OEM’s due to their increased need for parts with geometric complexity. CNC milling tools perform drilling and cutting machining processes. CNC milling machines and tools are incredibly versatile and produce custom, precision parts for a wide variety of industries and applications.

Three things an OEM requires from a CNC Milling Machine service

Precise CNC Milling



Precision is essential to part quality. OEMs have specific tolerances, and design parameters that every part ordered must meet to fit smoothly into the overall project upon assembly. In addition, most parts require machining on multiple surfaces at various angles with precise dimensions. EMI’s team of highly skilled CNC craftsmen have the experience and expertise needed to produce close tolerance components with precision accuracy.

Speed and Efficiency

CNC milling machines are best suited for running parts in production quantities. A conventional CNC can sometimes take hours to set up. However, more modern CNC machines are designed to minimize setup time. A full-service CNC machining service such as EMI maximizes efficiency and minimizes operator error by investing in experienced craftsmen and modern CNC milling machines.

Quality control

All reputable CNC machining services check their parts. However, those CNC milling machine services that go above and beyond “checking” stand out from the rest. Having an ISO 9001:2015 certification helps ensure that products consistently meet requirements and quality is routinely managed.

Elemet Manufacturing machines custom CNC parts for clients of all sizes in a wide variety of industries. Our clients trust us to deliver high-quality parts that meet their precise specifications fast. Interested?

The CNC milling machine is the heart of the precision CNC machining process.

Man Programming CNC Milling Machine

One of Elemet Manufacturing’s core service offerings is CNC milling machine services. CNC milling machines use computerized controls and translated codes from CAD and CAM software to perform automated machining functions on the raw metal stock.  Metal sheets or blocks are placed in a vise on a table below a spindle that spins rotary cutting tools to remove excess material from the raw metal as it is fed into the milling tool.

The main parameter that determines the capabilities of a milling tool is the number of axes. A basic 3-axis CNC milling machine has three movement axes. X=Left to Right.  Y = Forwards and Backwards. Z = Up and Down. The three axes of motions let the spindle spin a cutter at high speed to carve away material to create unique shapes, slots, holes, and details in a part. The type of cutting tool defines the shape of the part.

Horizontal and Vertical Machining provide efficiency and speed.

Horizontal CNC Milling Machine

Many machine shops use only one type of milling center. Our horizontal and vertical milling centers provide very different sets of advantages. An OEM or designer’s project shape, part volume, and required machining features benefit from the versatility and efficiency of dual machining mill types. In addition, our vertical and horizontal mills transform complex manufacturing processes into a single setup providing faster turnarounds and cost-efficient CNC machined parts.

A Vertical CNC milling machine features vertically-oriented tooling with rotating cylindrical cutters that can move along vertical axes to make plunge cuts and drilling. It is instrumental in die sinking.  This design makes them suitable for end milling operations, which use tools with teeth on the periphery and face.

A vertical CNC milling machine is ideal for:

  • Box type parts, such as gearboxes, spindle boxes, and gear pump shells
  • Complex curved parts, such as cams and mold cavities
  • Specialty or irregular parts, such as brackets and braces

Horizontal CNC milling machines have horizontally oriented tooling with rotating cylindrical cutters that can move along horizontal axes to create the shapes, slots, details, and holes of a part. As a result, they have faster processing speeds and can produce complex components in fewer operations.

A Horizontal CNC milling machine is ideal for:

  • Large or heavy parts with expansive surface areas
  • Specialty or irregular parts
  • Components that require machining on multiple sides
  • Applications that call for slots, grooves, pocketing, and facing

A 4-axis CNC milling machine service provides precision machining of complex parts. 

4-axis CNC Milling Machine

EMI offers 4-axis CNC milling machine services that can cut part geometry and complex or intricate shapes that other machining methods can’t match. By combining several stand-alone operations into one, the service can achieve:

  • Increased Accuracy
  • Reduced Part handling
  • Eliminating Multiple setups
  • Reduced Cycle time
  • More Efficient Production

The spindle head on a 4-axis CNC milling machine operates closer to the workpiece, which permits:

  • use of shorter cutting tools with less vibration
  • operation at higher cutting speeds
  • tighter tool movement
  • improved surface finishing

When a 3-axis CNC milling machine cannot accomplish the part complexity the client requires, a 4-axis CNC milling machine is an efficient, high-quality solution. 

Applications for CNC Milling Machine Services

CNC milling is especially valuable for producing large parts that demand significant floor space, such as aircraft and aerospace panels or components. It also supports projects for:

  • Commercial applications
  • Building and maintenance
  • Electronics
  • Medicine
  • Security
  • Recreation
  • Transportation
  • Automotive
  • Industrial and O.E.M.
