What is CNC milling services?

CNC milling uses rotary cutting tools to remove product from workpieces to produce complete parts and products. This manufacturing process is suitable for many steel, plastic and wood products and has the advantages of being able to process with high precision and to create complex geometric shapes, from fine small parts to large industrial components. For CNC milling, Mastersdex's engineers use programming software to determine the strategy and cutting parameters based on the part design. Prepare the workpiece and the appropriate tool, and accurately position the workpiece. Start the milling machine, the tool according to the program in the multi-axial motion cutting. Test the quality after completion, and adjust the program or secondary processing if there is a problem. Mastersdex also offers more advanced CNC milling services for 5-axis machines, which can be generated and get rid of high geometric complexity without the need for multiple equipment arrangements, as well as 3-axis milling, 4-axis milling processes to manufacture parts from more than 20 plastics and metals, combined with various surface treatments such as anodizing. Modified car parts processing to do the most, get a satisfactory response from all guests.

Mastersdex CNC Milling Capabilities

Mastersdex provides top-notch CNC milling services with 3-axis, 4-axis, 3+2-axis, and continuous 5-axis machining for accurate CNC milling parts. Small batch or mass production,Mastersdex always the best choice for you.

3 Axis CNC Milling Services

There are three linear axes, X, Y and Z. The tool can only move in a straight line in these three perpendicular directions, and the processing is mainly to mill the plane and simple three-dimensional shape of the workpiece. For example, when processing a cuboid part, a 3-axis milling machine can do a good job of milling six planes, but it will be limited for complex surface processing. However, three-axis CNC machine tools are the most common type, three-axis machining technology is mature, and the advantage is that the cost of three-axis machining per hour is low.
Mastersdex offers 3-axis CNC machining services for both metals and plastics at a reasonable price.

4 Axis CNC Milling Services

A rotating axis (usually the A or B axis) is added to the three linear axes X, Y, and Z. This gives the tool more freedom in the machining process. For example, the A-axis can be rotated around the X-axis, so that when machining some workpieces with inclined surfaces or complex shapes on the cylindrical surface, the tool can be better fitted to the surface of the workpiece through the rotation axis. In the processing of aerospace parts and modified car parts, 4-axis machining can better meet the processing requirements of high-precision complex shape parts.
With Mastersdex milling services, you can get machined parts with better surface finish and tight tolerances.

5 Axis CNC Milling Services

Two rotating axes are added to the three linear axes (commonly A and B axes or A and C axes combined). This configuration allows the tool to approach the workpiece from more angles, allowing for more complex movements in space. Because it can reduce the number of clamping, and can complete the processing of multiple faces and complex shapes in a single clamping, it is used in aerospace, high-end molds, precision medical devices, high-end modified auto parts and other industries with high shape accuracy and surface quality requirements Mastersdex has both 3+2-axis machines and continuous 5-axis machines. Our 5-axis CNC milling services will save time, enhance efficiency, and reduce price.

CNC Milling FAQs

1. What are the different types of machining processes?

The two primary CNC machining processes are CNC turning and CNC milling. Other machining processes include drilling, gear hobbing and electrical discharge machining,grinding among others.

2. What tolerance standards do you guarantee?

Parts machined with metal will follow ISO 2768-m (medium) or ISO 2768-f (fine). Parts machined with plastics will follow 2768-m (medium). Geometric tolerances down to ± 0.001mm are possible but must be clearly indicated in technical drawings. We can achieve tighter tolerances on shafts with up to H7 fits with manual quoting and on occasion tighter.

3. What are the minimum and maximum dimensions you can machine?

We offer CNC milling (3-axis, 3+2-axis and 5-axis) and turning. Milled parts can be machined up to 2000 x 1500 x 300 mm for 3, 3+2 axis CNC milling. For 5-axis milling, the maximum part size is 650 x 650 x 300 mm. The maximum diameter for CNC turning is 431mm, length 990 mm. Minimum part dimensions recommended are around 2 x 2 x 2mm.The minimum for feature dimensions is 0.5 mm.

4. What cosmetic standards do you guarantee?

Deburing and edge breaking are standard procedures for all CNC machined parts. lf there are any critical edges that should be left sharp, they must be clearly indicated in technical drawings. Surfaces will be free of defects such as scratches, dents, stains, blemishes, hanging marks, minor defects. Surfaces indicated ascritical (primary (a) side, as indicated on the technical drawing) will be free of mill steps and other marks. For the secondary (b) side, minor hanging marks and up to 2 minor defects are acceptable. A number of post-processing and finishing methods can be applied to improve the surface roug hness, visual properties andwear resistance of machined parts.

5. What types of threading options are available?

We offer UNF, UNC, and metric threads for machining along with coil and key inserts. These are available on both milled or turned CNC parts.

6. Is there a minimum order quantity (MOQ) for CNC machining at Mastersdex?

Mastersdex caters to both one-off prototype and large-scale production runs. Thus, there is typically no strict MOQ. Whether you need a single part or thousands, Mastersdex aims to provide a solution.

7. How long does it take to receive a part once an order is placed?

Lead times can vary based on the complexity of the design, the chosen material, and the current workload. However, one of the advantages of CNC machining is its speed, especially for simpler parts. Once the setup is complete, machining times can be relatively quick. Parts machined as fast as 1 day! But for an accurate estimate, it’s best to request for quotes directly.

8. How can I reduce the cost of my machined parts?

The main costs associated with CNC machining can be grouped into machining time, start-up costs,material costs, and feature costs. To reduce costs you need to understand the impact of these factors on cost. The best way to reduce machining time is to design features that can be machined quickly, for example by choosing the correct radii for internal corners, reducing cavity depth, increasing wall thicknesses, limiting thread length and designing holes with standard sizes. Material costs can be reduced by considering the size of the blank required, and the cost and machinability of the bulk material (softer alloys are faster to machine). Start-up costs can be reduced by reducing the number part rotations or repositioning required to finish thepart, for example by separating geometries into multiple parts that can be assembled later. Feature costs can be reduced by only usina tolerances when strictly necessary, removing all text & lettering and avoiding multiple surface finishes.

9. What are the advantages of CNC machining?

Product designers and engineers choose CNC machining to rapidly produce prototypes and production parts. The manufacturing technology offers a high level of precision, engineering-grade materials, quick-turn lead times.

10. What industries use CNC machinery?

Industries that use CNC machining include aerospace, automotive parts manufacturing, medical machine manufacturing, transportation, defense, and marine industries, along with oil and gas industries and electronics. CNC machining has allowed these industries to become more efficient at mass-producing custom CNC parts.
