CNC milling is a subtractive manufacturing process. It starts by fixturing a block of metal or plastic material inside the CNC mill. Using G-code, the CNC machine is programmed to rapidly mill out parts from the block of raw material. Our 3- and 5-axis CNC machines are equipped with various toolsets to maximize efficiency and production speed.

Machined plastic parts are left as-milled, which typically means they show visible tool marks. Some metal parts allow more finishing choices like anodizing and chromate plating. When the run is complete and your required surface finish is applied, parts are boxed and shipped shortly thereafter.

Surface Finish: As per the requirement shared in the CAD drawing

post processing

Basic: Deburring, Buffing, Tapping, Lapping, Sand Blasting 

Anodizing:  Anodizing is an electro-chemical process that converts metal surface into a decorative, durable, corrosion resistant anodic oxide finish.

Chrome Plating:  Chrome plating helps protect parts from corrosion while adding electrical conductivity and the ability to paint the part. Steel and iron based metals require pretreating with zince before applyign chromate.

Spray Painting: Spray painting is a painting technique in which a device sprays coating material (paint, ink, varnish, etc.) through the air onto a surface

Powder Coating: Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.

Frequently Asked Questions

CNC mills come in 3-axis, 4-axis, and 5-axis configurations:



Milling is suitable for many different features, including threading, chamfering, slotting, etc. This allows for producing complex designs on a single CNC milling centre with enviable accuracy. The tolerances for CNC machining are around +/- 0.1 mm.

The creation of these aforementioned features requires a variety of different milling operations:

  • Surface milling
  • Face milling
  • Angular milling
  • Form milling
  • Profile milling
  • Gear milling, etc.

Tool offset refers to the allowance made by a milling machine to design the cutting tool and shift its position. It ensures the CNC machine is operating on the right part of the workpiece.

Just like other CNC machining services serving their utmost to several industries around the globe, the CNC milling procedures and services are also working to their maximum to facilitate businesses and industries. Depending on the type of machined part, prototype scale, or production line, the following are some of the industries that are directly getting facilitated with the CNC milling services. 

  • Electronics industry
  • Medical industry
  • Automotive industry
  • Marine industry
  • Agricultural industry
  • Machine tool industry
  • Military industry
  • High-tech industry
  • Food industry
  • Aerospace industry
  • Semiconductor industry

Hence, CNC milling services are best to give your machined parts and prototypes a new dimension and fits in the big picture. Being a budding machining service, the CNC milling procedures are now carried out in machine shops to give a reliable, strong, and finished custom machined part. 

1. Cost Efficient
80% of aspect and mechanical parts can be CNC milled within minutes or even seconds by optimizing the tool paths and using special cutting tools. With automation set up, CNC milling is super cost-efficient for mass production comparing with additive manufacturing in most of the cases.

2. Materials & Finishes Options
Besides of fast turnaround time, various type and spec of the plastic, metal block are available for milling, and different type of surface finishing is available for CNC milling parts, such as painting, anodizing and chroming. It’s great a combination of function and aspect.

3. Unlock Complexity
Because the cutting tool of a milling machine can approach the workpiece from several different angles, it is possible to create complex shapes CNC parts, with more axis, we can create parts of greater complexity. If a CNC project demands an irregular shape, milling is often the best bet.

While potentially any solid, stable material can be milled, we have a standard selection of raw material including hard plastics and aluminum, various steels, titanium, magnesium, brass, copper and other alloys.

Note that some hardened steels may be too hard to CNC machine, or else would require specialty cutting tools and longer processing times. Soft elastomers or plastics may also be impossible to mill since they cannot be held in a fixed position or would change in shape under the pressure of the cutting tool.

Rates vary with process and we employ many processes at THINK3D. Basing part or project costs on factory rates assumes all similar factory operate at same level of productivity employing the same level of employees and equipment. Certainly that is not the case. We prefer to provide pricing upon detailed review of your Drawings. This approach is much more valuable to the customer.

Average is difficult to define given the diverse nature of materials and processes utilized at THINK3D. We consider ourselves as a “Quick Turn&Milling” operation. Often providing much shorter lead times than typical industrial cutting or machining operations. Additionally giving the fact that we have so many processes in house it allows us to do the entire project (or a large piece of it) saving the customer the time and inefficiencies of utilizing several companies.
Depending on the part complexity and capacity of our company typical lead times range from 2-6 weeks after receipt of order.

Currently we can handle machined parts up to 850 x 510 x 510 mm.

Hi Neha Chandel,

We aren’t in the business of selling CNC Machines. So, we mayn’t be of much help here. There are many brands out there that sell CNC Machines like ACE Micromatics, HAAS, DMG Mori. You can reach out to them with the request. Hope this helps.

Would be delighted whether possible for a Die of 650mmX375mmX375mm at CNC milling machine available at your facility.
