Instant online quoting is available for all types of CNC turned metal and plastic parts. If you cannot find the required stock material, select "Other" from the material drop-down menu on the quoting page, and submit after clarifying part features, tolerance requirements, inspection needs and required quantity. Our professional engineering team will conduct an evaluation.
Different surface treatment methods can improve the appearance, corrosion resistance, wear resistance and other properties of parts. EPTAHUB provides multiple standard surface treatment options and supports custom services.
This is the surface treatment option with the shortest lead time. The part surface will have obvious tool marks, and there may be sharp edges and burrs, which can be removed if needed. The surface roughness is equivalent to 125 microinches Ra.
After this treatment, the part surface presents a smooth matte texture.
Type II: Can form a corrosion-resistant surface. Parts can be anodized in multiple colors, among which clear, black, red and gold are the most common. This treatment method is usually applicable to aluminum alloys.
Type III: The oxide layer is thicker, and in addition to the corrosion resistance of Type II, it can also form a wear-resistant layer.
This process involves spraying powder coating onto the part surface, and then placing the part in an oven for baking. After this treatment, the part surface forms a strong, wear-resistant and corrosion-resistant coating, whose durability is better than that of conventional painting processes. A variety of colors are also available to meet your desired appearance effect.
If you cannot find the surface treatment method you need, you can submit a Request for Quotation (RFQ), and we will research a suitable surface treatment process for your custom turned parts.
Since CNC technology can be applied to almost all materials, it is very suitable for rapid tooling, i.e., making fixtures or molds.
CNC turning has a variety of material choices, low unit cost and fast production speed, making it an ideal choice for prototyping.
CNC lathe turning technology can achieve high-quality surface treatment, provide a variety of material choices and precise tolerance control, making it well suited for mass production parts.
Multiple surface treatment methods can be selected for solid metal and plastic parts according to precise design specifications.
More than 50 kinds of metal and plastic materials are available, and CNC machining services cover a variety of certified materials.
According to customer needs, high-precision machining with a tolerance range of ±0.001 inches to ±0.005 inches can be provided.
CNC machining technology is suitable for the production of 1 to 10,000 CNC machined parts, with excellent scalability.
| Description | General Tolerance or Standard |
|---|---|
| Dimensional Distance | For shaping dimensions (length, width, height, diameter) and positioning dimensions (position, concentricity, symmetry), the tolerance is ±0.005 inches. |
| Orientation and Form Dimensions | Within the range of 0 - 12 inches, the tolerance is ±0.005 inches, and the angle tolerance is 1/2 degree. For dimensions of 24 inches and above, please refer to EPTAHUB Manufacturing Standards. |
| Edge Condition | By default, sharp edges will be chamfered and deburred. If there are critical edges that must remain sharp, they need to be indicated on the drawing and clearly marked. |
For detailed tolerance information of each process, please refer to EPTAHUB Manufacturing Standards. Unless other tolerance requirements are agreed upon in the quotation, we will process and ensure that the tolerance meets the above standards.
CNC lathes (also known as turret lathes) are very suitable for processing various symmetrical cylindrical or spherical parts. Its typical feature is that the lathe drives the workpiece to rotate through vertical or horizontal axes, while the fixed forming tool moves around the workpiece along a roughly straight path. The process of cutting a workpiece on a CNC lathe is called turning.
CNC lathes adopt a subtractive machining method to shape the desired shape. First, G-code is generated, and then the bar stock is loaded into the chuck of the lathe spindle. The chuck fixes the workpiece, and the spindle drives the workpiece to rotate. When the spindle reaches the set speed, the fixed cutting tool is brought into contact with the workpiece, and material is removed until the desired geometric shape is obtained.
Turret lathes can perform a variety of machining operations, including facing, threading, knurling, drilling, boring, reaming and taper turning. Different machining operations require tool changes, which may increase costs and setup time. After all machining operations are completed, the part is cut from the blank for subsequent post-processing. After that, the CNC lathe can repeat the next machining operation with little or no setup time.
There are various types of CNC lathes, among which the most common are 2-axis CNC lathes and Swiss-type lathes. The unique feature of Swiss-type lathes is that the blank is fed through a guide bushing, allowing the tool to cut close to the support point. This design makes it particularly suitable for processing slender CNC lathe parts and micro-machined parts. Some Swiss-type lathes are also equipped with a second turret, which can be used as a CNC milling machine and can perform multiple machining operations on the same equipment without transferring the workpiece to other equipment. Therefore, for the processing of complex turning parts, Swiss-type lathes are a cost-effective CNC lathe processing equipment choice.
Similar to CNC milling machines, CNC lathes are easy to set up and have high repeatability, so they can be used for rapid prototyping and production from small to large batches. Multi-axis CNC turning centers and Swiss-type lathes can complete multiple machining operations on the same equipment. For complex geometric parts that require multiple equipment or multiple tool changes on traditional CNC milling machines, this kind of equipment is a cost-effective choice.
