CNC Milling service: Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.

CNC Turning service: Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates. Usually the term “turning” is reserved for the generation of external surfaces by this cutting action, whereas this same essential cutting action when applied to internal surfaces (holes, of one kind or another) is called “boring”. Thus the phrase “turning and boring” categorizes the larger family of processes known as lathing. The cutting of faces on the workpiece, whether with a turning or boring tool, is called “facing”, and may be lumped into either category as a subset. Turning can be done manually, in a traditional form of lathe, which frequently requires continuous supervision by the operator, or by using an automated lathe which does not.

5-axis CNC machining: 5-axis CNC machines can produce parts with complex geometries and increase productivity by minimizing the number of machine setups. Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material. This type of machining was originally performed mechanically on large complex machines. These machines operated on 4, 5, 6, and even 12 axes which are controlled individually via levers that rested on cam plates. The cam plates offered the ability to control the tooling device, the table in which the part is secured, as well as rotating the tooling or part within the machine.

Minimising the cost of CNC parts

Increasing the quantity from 1 to 5 can decrease the unit price by more than 50%!

The startup costs are relatively high in CNC machining thus the quantity greatly affects the unit price. For low quantities, the costs are mainly related to setup, fixtures and programming representing a big percentage of the cost. For large quantities though, they get almost eliminated as these costs are spread over many parts.

The drop in unit price is significant following an exponential trend. Even a small increase in quantity can decrease the unit price significantly. Ordering very high volumes (> 100 parts) reduces the unit price by 5 to 10 times.
