FAQs
Q1: What level of precision can CNC turning achieve?
Standard precision CNC turning can achieve a tolerance of ± 0.01mm, precision machining can reach ± 0.005mm, and with grinding processes, it can reach ± 0.002mm, suitable for high-end automation component requirements.
Q2: What materials are commonly used for robot joint components?
Mechanical parts for robot joint turning are made primarily of 7075 aluminum (lightest), 17-4PH stainless steel (corrosion resistant), and 20CrMnTi (wear resistant), which can be selected according to needs.
Q3: What is the minimum order quantity for small batch custom CNC parts?
JS Precision allows to place orders with the minimum of 1 piece. For 1-10 pieces orders, debugging costs need to be shared, while 10-50 pieces orders are most cost effective and are suitable for small batch testing requirements.
Q4: What are the main components of CNC turning prices?
Price of precision CNC turning mainly comes from the materials (30-40%), machining, heat treatment, and inspection. Surface treatment is not included and will be an extra charge.
Q5: How long does it take to get a sample after providing drawings?
Simple turning parts can be sampled in 7-10 days. Complex parts require 2-3 weeks as they not only include main processes but also material acquisition and script debugging time.
Q6: What does AGMA Grade 12 gear mean?
AGMA Grade 12 represents the finest gear level attainable through CNC machining of excellent quality. The tooth pitch error is only ±0.007mm and gear grinding is inevitable. This type of gear can be used for high speed precision transmission.
Q7: How to ensure batch consistency?
We utilize SPC process control + first piece full inspection + batch sampling inspection to ensure batch consistency of turned parts. The core dimension CPK value is 1.33, which complies with the standards of precision machining.
Q8: Does anodizing affect dimensions?
Yes, anodizing does change the dimensions of turned parts. The usual thickness of the film is from 5 to 25μm. If precision CNC turning is done, the reciprocal dimension normal have to be made allowable.
Q9: What is the difference between CNC turning and Swiss type automatic lathes?
Swiss type automatic lathes offer the best solution for machining slender shafts with diameters <42mm, delivering higher precision levels. CNC turning centers are the tools that allow to produce large diameter, complex parts, and they have a wider machining range.
Q10: Are there any special requirements for export packaging?
Exported turned parts are packaged with rust preventive oil + VCI vapor phase rust inhibitor paper + independent compartments + vacuum packaging, which is an effective method to prevent contamination, corrosion, and damage during sea transport.
Q11: What tests are necessary at the prototype stage?
The prototype phase needs comprehensive CMM inspection, surface roughness measurement, hardness testing, and assembly verification to thoroughly check the turning accuracy and the effectiveness of component assembly.
Q12: How to identify a trustworthy CNC machining supplier?
If you want to select a reliable precision CNC turning supplier, it is mandatory to check their machining equipment, quality certification (ISO/AS9100), and review cases of automated component machining within the same industry.
