Precision CNC Milling Services with the Options Your Part Requires

Precision Milled Parts

P&F milling capabilities include both horizontal and vertical technologies utilizing up to 5 axis to produce both prismatic and complex geometries from a variety of materials including but not limited to aluminum, carbon steels, stainless steels and plastics. Our milling processes are capable of producing products as large as 30x64x20 and meeting tolerances in the .0001″ or .001 micron range while getting the desired process capability indices.

Horizontal and Vertical Milling

The choice between horizontal and vertical milling comes down to the shape of the part and how many sides need work. Vertical mills suit parts to hold the spindle upright, which suits parts that are worked mostly from the top down and gives the operator a clear view of the cut. Horizontal mills hold the spindle parallel to the table, so cutters can reach the sides of a part and remove material across a wider face. Many parts move through both setups. A block might get its top pockets cut on a vertical machine, then go to a horizontal machine to have its side faces squared and drilled.

What 5-Axis Machining Adds

A 3-axis machine moves the part along X, Y and Z. A 5-axis machine adds two rotational axes, so the cutting tool can approach the workpiece from angles that would otherwise require the part to be repositioned by hand. That matters for parts with angled holes, contoured surfaces or features on several faces. Fewer setups means less chance of stacking up small position errors each time a part is moved and re-clamped and it also lets the shop cut shapes that would be difficult or impossible to reach in a single orientation.

Materials We Mill

Aluminum, carbon steels, stainless steels and plastics all behave differently at the spindle and each calls for its own speeds, feeds and tooling. Aluminum cuts freely and allows aggressive removal rates and carbon and stainless steels demand slower feeds and cutters that hold up to heat. Plastics can deflect or melt if the tool rubs instead of shearing, so feed rates are set to keep the cutter moving through the material.

Size and Tolerance Range

Our milling processes handle parts as large as 30x64x20, which covers a wide range of housings, plates and machined blocks. Tolerances go as tight as .0001″ or .001 micron and we track process capability indices so you can see how consistently the process holds those numbers run after run.
