Available CNC Turning Materials at Kingsun
At Kingsun, we invite you to familiarize yourself with the selection of NC milling materials we offer. We have plenty of quality restructuring materials which we know will serve your machining purpose. Possibly the hardest ones, the range of metals, plastics or composite materials combinations to choose from, will ensure endurance and high precision in your work.

CNC Turning Tolerances for Plastics and Metals (ISO 2768 Standards)
It is important to know the tolerance of various materials during the CNC turning process to enable precision through understanding. Below is a table that shows tolerances for plastics and metals in accordance with ISO 2768 standards covering a range of nominal sizes.
Nominal Size Range (mm) | Plastics Tolerance (ISO 2768-m) | Metals Tolerance (ISO 2768-f) |
---|---|---|
0.5 to 3 | ±0.1 mm | ±0.05 mm |
Over 3 to 6 | ±0.1 mm | ±0.05 mm |
Over 6 to 30 | ±0.2 mm | ±0.1 mm |
Over 30 to 120 | ±0.3 mm | ±0.15 mm |
Over 120 to 400 | ±0.5 mm | ±0.2 mm |
Over 400 to 1000 | ±0.8 mm | ±0.3 mm |
Over 1000 to 2000 | ±1.2 mm | ±0.5 mm |
Over 2000 to 4000 | ±2 mm |
- Plastics Tolerances: These tolerances are mostly wider as compared to that of metals, catering for the material’s plasticity and thermal expansion. The tolerances range oscilate from ±0.1 mm for smaller dimensions which are maximum upto 6 mm and increase to ±2 mm for larger dimensions which may go upto 4000 mm.
- Metals Tolerances: Metals rather have stricter tolerances which begin from ±0.05 mm on dimensions between 6 mm, it sound in this instance machine are quite bullocky. The Cynthia however is tolerant in dimensions progress up to one thousand income-portion two hundred segments.
Finishing Options for CNC Turning Service
In CNC turning services, choosing the correct finishing option is essential to enhancing the aesthetics, mechanical strength, and usability of machined parts. Different finishes offer specific advantages with respect to material and purpose, and an optimal choice can determine the quality and longevity of CNC turned parts.
- Purpose: Mostly applicable for aluminum parts, anodizing is an electrochemical technique that transforms metal surfaces into a highly resistant anodic oxide.
- Benefits: This type of coating reduces corrosion, increases the wear resistance of the surface, and can also be painted different colors to meet the customer’s needs.
- Purpose: A dry finishing process that applies powdered paint through the means of electrostatic and sleekies that are then oven cured.
- Benefits: Produces an impact resistant and chipping resistant coating that tough, durable and does not scratch easily. Comes in many colors and textures that is very effective whenit comes to corrosion and wear.
- Purpose: Performed to achieve a high degree of glossy quality surface which is free from all the minute scratches that may be present.
- Benefits: Adds to the aesthetics of the component thus is applied on parts that are meant to be very attractive in appearance or are meant to have low friction.
- Purpose: Involves the deposition of a thin layer of metals such as nickel, chrome or gold onto the surface of the part using processes including electroplating or electroless plating.
- Benefits: Helps prevent or makes it very hard for the material i.e. the part to rust enhances hardness toward the surface, conductivity and also decorative appeal.
- Purpose: The process of bead blasting is the removal of solid material by shooting a surface with fine glass beads or any dense medium.
- Benefits: Yields an even, matte or satin finish, which is the most suitable surface for parts that require painting or coating. In addition, it can level the surface and even out rough edges.

Advantages of CNC Turning
CNC turning provides numerous benefits that enhance modern manufacturing, making it an ideal option for businesses aiming to improve production capabilities while ensuring high quality and efficiency.

CNC turning machines replicate accuracy and precision and other relating characteristics of manufacturing system whereby the components are all manufactured to required specifications all the time. This precision process reduces and pollution and improves the product of the manufacturer.
The mechanization features of CNC turning enhances the rate of production and decrease the time required for completion of the task. This is important especially while working within time limits and increases business gains.
CNC turning machines are able to make as many identical pieces as required, which is one of the main advantages of this type of machine tools. This ‘repeatability’ guarantees controllable quality in mass batches, which is paramount in manufacturing processes.
CNC turning machines can easily produce the complex geometries and intricate designs. This helps the engineers and the designers in terms of creativity as it leads to new innovative ideas and products.
CNC turning is quite flexible in orientation for different types of materials, including metals, plastics as well as composite materials. This adaptability makes it useful in many industries and operations.
There are substantial initial costs during the setup phase. However, production using the CNC turning brings about complete savings of costs associated with the efficiency, speed and quality of turning. Material wastes and man power costs decreases options which improve its economy.
