What is CNC Milling?

CNC Milling is the most common and popular machine in CNC manufacturing.Using a cutting tool mounted on a rotating spindle to selectively remove material from a block of raw substrate. The workpiece is rigidly mounted to a table, and this table moves or rotates on different planes so the tool can work at many angles. Sophisticated CNC milling machines can have 5 or more axes of independent motion to make more complex shapes or to avoid having to move the workpiece to a separate machine.

It'svery beneficial to products and parts, and improve efficiency and quality.

What do we pay attention to when choosing materials for CNC Milling?

As with all machining processes, when selecting a material for a milling application, several factors must be considered, such as the properties of the material (i.e., hardness, tensile and shear strength, and chemical and temperature resistance) and the cost-effectiveness of machining the material. These criteria dictate whether the material is suitable for the milling process and the budgetary constraints of the milling application, respectively. The chosen material determines the type(s) of the machine tool(s) employed and its/their design(s), and the optimal machine settings, including cutting speed, feed rate, and depth of cut.

This Process is Suitable for Machining a Wide Range of Materials Such as Metal, Plastic, Glass, and Wood, and Producing a Variety of Custom-Designed Parts and Products, Including:

Metals

Aluminum Alloy, Stainless Steel, Brass,Copper etc.
CNC milling is a popular way to produce both rapid prototyping of metal parts and final parts.
Plastics

ABS, PC, PMMA, PA, POM, PP, PVC, PEEK etc.
Plastics CNC milling of plastics is the most common and economical way to create rapid prototypes and review the appearance and function of your design

Kaierwo can also finish excellent surface finish, including: as machined, smooth, painting, anodize, bead blasting, oxidation, polishing, powder coating, plating, knurling , brushing, Passivation etc.

FAQ

1.How to deal with surface treatment problems?

Sample color identification and dispensing ensure batch color consistency, strengthen manual inspection, avoid the defective products.
2.What is the best pre-treatment for prepping Aluminium castings?

Sandblasting Aluminium castings prior to finish is most common. E-coating would be a great economical operation. Chemical film is another treatment. It acts as an excellent primer for wet coat finishes on Aluminium.
3.How surface finishing works?

Almost all surface finishing processes improve either the aesthetic appearance of the product or its mechanical or chemical properties. Each surface finishing process achieves this in a slightly different way.
4.How much material is removed during the Sandblasting process?

During the Sandblasting process, the surface of a part is peened off, no part material is removed or lost at all. This process is typically used to soften parting lines or eliminate any sharp edges that could impact your line workers in the assembly process. It can also be used to give a uniform finish.
5.What the benefits of surface finishes?

Improve the appearance of your finished products, Improve resistance to wear and tear, Ensure good adhesion of paint, Meet your brand requirements...
