What is CNC Milling?
Milling is the process of removing material from a solid blank to create a finished or semi-finished shape. The process is guided by your CAD file, optimized to create a physical copy of your digital design.
In CNC milling, the workpiece is held in a rigid vice or holding fixture, mounted on a work table. This table rotates as well as pivots, making two axes of movement. Cutting tools mounted on a rotating spindle remove material to create a variety of complex geometries and part features on the workpiece. The real advantage of a multi-axis milling machine, such as our Haas UMC-750 milling center, is that the worktable and the spindle move on many axes independent to one another, providing not only accuracy and repeatability but also versatility.
From 3-axis basics to intricate 5-axis projects, our precision CNC milling makes your designs come alive with unmatched accuracy and craftsmanship.
CNC Milling Tolerances
Future Parts ensures precision with our CNC Milling Tolerance standards. We commit to exact measurements, benefiting clients with consistent, high-quality results, optimized for search visibility. Our standard tolerances for CNC milled metals are ISO 2768-m and ISO 2768-c for plastics.

The Feature of product
- CNC milling is ideal for making angled shapes, slots and channels, chamfers, holes, curves and flat surfaces, among many other features. A CNC mill removes large amounts of material fast with high accuracy, while producing a good surface finish. Milling can be done on any rigid material, though we primarily work with metals and plastics. Of all available CNC machining processes, milling is the most versatile.
- Milling is used not only to make finished parts but also to build tooling for plastic injection molding and pressure die casting. Set-up time is minimal, so a CAD file can be translated into a finished part in a matter of hours. Because there is no need to make other specialty tools, you aren’t committed to a minimum order quantity so the process is very cost effective with little waste.

Polishing
|
Polishing is the process of
creating a smooth and shiny
surface, either through physical
rubbing of the part or by chemical
interference. The process produces
a surface with significant
specular reflection, but in some
materials can reduce diffuse
reflection.
