CNC Turning Service Tolerances

As an ISO 9001 certified CNC turning company, Cesar machines precision CNC turning parts to meet strict dimensional tolerance requirements. Based on your design, our CNC lattes can reach tolerances of up to ±0.005”. Our standard tolerances for CNC milled metals is ISO 2768-m and ISO 2768-c for plastics.
Description
Maximum Part
Size
Typically up to 500 mm in diameter and 1500 mm in length, though larger sizes can be accommodated with specific equipment.
Minimum Part
Size
As small as 1 mm in diameter, depending on the material and machining setup.
General
Tolerances
Standard tolerances of ±0.01 mm; tighter tolerances down to ±0.005 mm can be achieved based on the material and complexity of the part.
Lead Time Standard lead times range from 3-7 days for small batches. Expedited services are available, reducing lead time to 24-48 hours depending on part complexity and material availability.

CNC Turning
Design Guidelines

Recommended Size
Radii Minimum internal radius of 0.5 mm recommended. Larger radii (up to 3 mm or more) can improve tool access and reduce stress concentrations in the part.
Threads and
Tapped Holes
External and internal threads can be precisely cut. Standard thread sizes from M1.6 and larger are feasible. Ensure a minimum thread length of 1.5 times the diameter for stability.
Minumum Wall
Thickness
Maintain a minimum wall thickness of 0.8 mm for metals and 1.5 mm for plastics to ensure structural integrity without compromising the machining process.
Text Engraving should have a minimum character height of 2 mm and a depth of at least 0.5 mm to ensure legibility after machining.
Holes Minimum hole diameter of 0.5 mm. For deep holes, maintain a diameter to depth ratio of 1:10 to avoid tool deflection and ensure hole quality.

How Does CNC Turning Work?

CNC turning is a subtractive manufacturing operation that uses computer-controlled lathes to precisely shape material into cylindrical parts. Initially, the design of the part is created using CAD software and converted into instructions for the CNC machine using CAM software. During setup, the correct cutting tools are installed, and a cylindrical workpiece is secured in the machine’s chuck, which holds and rotates the material.

As the machine operates, the workpiece spins at high speeds while the cutting tools move along various axes to carve, cut, and shape the material based on the program’s specifications. Operations such as facing, threading, knurling, and drilling are performed during this stage. A coolant is often applied to prevent overheating and to wash away debris.

After machining, the part may undergo additional finishing processes like sanding or polishing. The final step involves a thorough inspection to ensure the part meets all the required dimensions and tolerances. This process allows for high precision and repeatability, making CNC turning ideal for producing complex parts efficiently.
