Frequently Asked Questions

What is the difference between straight and angular wheel head CNC cylindrical grinding machine?

A straight wheel head CNC cylindrical grinding machine grinds the outer diameter (OD) of cylindrical components. An angular wheel head (like Elitech e GRIND series) is set at 30° and can simultaneously grind OD and face in one setup — ideal for shoulder and stepped components. The ECG straight series is best for pure OD cylindrical grinding applications.

What CNC controller is used in Elitech ECG series?

The ECG series is available with Siemens 808D Advanced or Fanuc 0i-TF Plus CNC controllers — both industry-trusted systems offering customizable grinding cycles, auto dressing programs, job storage and real-time cycle monitoring for reliable automated production.

Can ECG series perform both plunge and traverse grinding?

Yes. The ECG series supports both plunge and traverse grinding in a single setup without unloading the component. Multiple grinding steps on different diameters can be completed in one automatic cycle — improving productivity and dimensional accuracy.

What grinding lengths are available in ECG series?

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

Which components can be ground on ECG series CNC cylindrical grinding machine?

The ECG series is widely used for precision OD grinding of transmission shafts, motor rotors, ER collets, fuel injection parts, cam shafts, automotive shafts, hydraulic components, bearing components and general precision engineering parts in medium to high production environments.

Is ECG series suitable for small scale industries?

Yes. The Elitech ECG series is specifically designed as an economical CNC cylindrical grinding machine for small and medium scale industries — offering full CNC automation at an affordable price, making it an ideal upgrade from hydraulic or NC grinding machines.

Is internal grinding possible on ECG series?

Yes. An optional internal grinding attachment with Ø60mm or Ø80mm spindle is available — enabling precision internal bore grinding up to 18000 RPM on the same machine, making it a versatile combined OD and ID grinding solution.

Does Elitech export CNC cylindrical grinding machines and offer after-sales support?

Yes. Elitech Machine Tools manufactures and exports ECG series machines worldwide with service network across India — Rajkot, Ahmedabad, Pune, Mumbai, Delhi, Bengaluru, Chennai and internationally in Singapore, Turkey, Africa and UAE. Contact sales@elitech.in for enquiries.
