CNC Milling


Protocase Tech Tip Video

CNC Milling is the removal of metal with a rotary cutter or other rotating cutting tool. With precise equipment, and a wide variety of tooling, we are able to cut just about anything, within tolerances of a few thousandths of an inch or less.

Engineers, innovators and scientists choose Protocase for custom CNC milling, because we are able to effectively and accurately machine custom parts and enclosures, with absolutely no minimum orders. We pride ourselves on our reliability and superior customer service. Contact us to get started.

Protocase's CNC Machining Division includes 5-Axis and 3-Axis milling, as well as CNC Turning and CNC Router. We offer CNC machining of aluminum, copper and other materials, both for sheet metal and bar stock.

Lead Time:

We are currently able to achieve lead times for CNC machined parts and enclosures that range between two days and 15+ days, depending on the complexity of your design.

Protocase 3-Axis Milling

Protocase 3-Axis CNC Milling

Protocase's 3-axis machining division has been operating since 2015. Our 3-axis milling machines allow us to cut at a high speed with smaller cutters.

Our machining services are ideal for prototypes, small run and larger-quantity orders.

Overview of Our 3-Axis Offering

3-axis machining employs cutting parts on three axes: the X, Y and Z axes. The machining tool removes materials in three basic directions that correspond to the axis of a flat surface.

3-axis machining is suitable for parts with shallow features, such as pockets and grooves.

Benefits of 3-Axis

  • • Efficient, accurate machining of simple parts and enclosures
  • • Wide variety of work holdings available

Protocase 5-Axis Milling

Protocase 5-Axis CNC Milling

Our 5-axis machining provides a vast variety of possibilities as to the part sizes and shapes we can effectively process in 2-3 days, with no minimum order. 5-axis machining offers the highest precision and quality available.

Protocase CNC machining services are ideal for prototypes and small runs, because our turnaround times are extremely fast and we readily accept orders of quantities as low as one.

Industries that use 5-axis machining:

  • • Aerospace
  • • Defense
  • • Oil & Gas
  • • Robotics
  • • Medical Technology
  • • Research & Development
  • • And more

Overview of Our 5-Axis Offering

5-axis refers to the number of directions in which the cutting tool can move. You can process five sides of a part in single setup, because the cutting tool moves across the X, Y and Z linear axes, as well as rotates on the B and C axes. This allows the cutting tool to approach the part from any direction.

5-axis CNC machining is the most technologically advanced CNC machining available on the market today.

Benefits of 5-Axis

  • • Complex shapes machined in a single setup
  • • Minimal setups means maximized productivity - you get your order as quickly as possible
  • • Virtually no need for complex fixtures or workholding
