Product Features & Benefits
- 5‑Axis Simultaneous Machining – Enables complex cylinder head features (valve guides, seat angles, oil galleries) to be completed in a single setup, reducing handling errors and cycle time by up to 40%.
- High Stiffness Structure – Heavy‑duty cast iron housing and pre‑loaded bearings provide vibration damping, essential for achieving tight tolerances on aluminum castings.
- Backlash‑Free Harmonic Drive – Zero lost motion ensures smooth contouring and excellent surface finish, even at high feed rates.
- Sealed Protection – IP67 rated sealing against coolant and chips, suitable for wet machining environments typical of automotive lines.
- Easy Integration – Compatible with most 5‑axis CNC controls; plug‑and‑play electrical interface with encoder feedback.
- Custom Clamping Options – Tailored T‑slot patterns, pneumatic or hydraulic clamping systems can be added for specific cylinder head fixtures.
- Low Maintenance – Long‑life harmonic drive and sealed bearings require infrequent service, maximizing uptime.

Frequently Asked Questions
- Q1: Can this rotary table handle cylinder heads of different sizes and weights?
- Yes, we offer table diameters from 400mm to 630mm (and custom diameters). Load capacity ranges from 600kg to 800kg, covering most passenger car and light truck cylinder heads. For heavier or larger parts, please provide your specific dimensions and we can recommend a suitable size.
- Q2: Is the table compatible with my existing CNC controller?
- Our rotary table supports common control interfaces such as Fanuc, Siemens 840D, Heidenhain TNC, and Mitsubishi. We also provide an optional analog interface that works with older controllers. Please specify your control model when ordering for a seamless integration.
- Q3: What kind of maintenance does the table require?
- The harmonic drive and bearings are pre‑lubricated and sealed. Under normal operation, we recommend checking the grease condition every 6 months. An optional automatic lubrication system can be added for high‑uptime production. No major maintenance is needed within the first 10,000 hours of operation.
- Q4: Can I use the table for both roughing and finishing operations?
- Absolutely. The high stiffness and zero backlash ensure consistent performance under heavy cuts during roughing, while also delivering the fine positional accuracy required for finishing the cylinder head combustion chamber and valve seats. Many customers use it for both stages in a single machine.
- Q5: What is the typical delivery time?
- For standard configurations (400mm/500mm tables with harmonic drive), lead time is approximately 25–35 working days. Customized solutions may take 40–50 days depending on the complexity. We ship via ports in Shanghai, Ningbo, Shenzhen, or Qingdao.
- Q6: Do you provide installation and training support?
- Yes, our technical team can offer remote or on‑site commissioning support. We also provide a detailed installation manual and parameter settings for your CNC. Custom macro programs for cylinder head machining cycles are available upon request.
- Q7: Is the table suitable for dry machining as well?
- The standard model is designed for wet coolant environments (IP67 seals). For dry machining with MQL (minimum quantity lubrication), we also offer a sealed version with optimized heat dissipation. Please specify your coolant type when ordering.
- Q8: What is the warranty period?
- We provide a standard 12‑month warranty from the date of shipment covering manufacturing defects. Extended warranties up to 24 months are available as an optional service. Our after‑sales team responds within 24 hours for any technical inquiries.
