Frequently Asked Questions

What is an NC cylindrical grinding machine?

An NC cylindrical grinding machine uses numerical control with servo motors on X and Z axis for semi-automatic precision OD grinding. The Elitech EMTU+ series uses an Omron NC control with HMI interface — offering auto grinding and dressing cycles without complex CNC programming, making it ideal for operators with minimal training.

What is the difference between NC and CNC cylindrical grinding machine?

An NC cylindrical grinding machine like Elitech EMTU+ series uses Omron NC control for semi-automatic grinding cycles — ideal for batch production at lower cost. A CNC machine like Elitech ECG series uses Siemens or Fanuc CNC with advanced programming for fully automatic complex grinding cycles — ideal for high volume precision production.

How many diameter steps can EMTU+ series grind in one setup?

The Elitech EMTU+ series NC cylindrical grinding machine supports auto grinding cycles for up to 6 different diameters in a single component setup — improving productivity and reducing component handling time for multi-step shaft grinding.

What grinding lengths are available in EMTU+ series?

The EMTU+ series is available in six models — EMTU+ 450, 600, 800 for shorter components and EMTU+ 1000, 1250, 1500 for longer shafts up to 1500mm. Maximum component weight between centers is 60kg for smaller models and 110kg for larger models.

Is NC grinding machine suitable for production?

Yes. The Elitech EMTU+ series is specifically designed for batch and medium volume production. Its auto grinding and dressing cycles reduce operator dependency, improve consistency and increase throughput — making it a cost-effective alternative to full CNC machines for medium production volumes.

What control system is used in Elitech EMTU+ series?

The EMTU+ series uses Omron NC control system with HMI interface — offering easy programming, real-time cycle monitoring and fault diagnostics. It provides reliable automation without the complexity and cost of full CNC systems.

Can EMTU+ series perform internal grinding?

Yes. An optional internal grinding attachment with Ø60mm (18000 RPM) or Ø80mm (14000 RPM) spindle is available for the EMTU+ series — enabling both external OD and internal bore grinding on the same machine.

Does Elitech supply NC grinding machines across India?

Yes. Elitech Machine Tools supplies and services NC cylindrical grinding machines across India — including Ahmedabad, Pune, Mumbai, Bengaluru, Chennai, Coimbatore, Rajkot, Delhi and all major industrial cities. Contact sales@elitech.in for enquiries and technical support.
