Precision Grinding for Demanding Industries

Engineered for the automotive, aerospace, and bearing industries, the Ghiringhelli Centerless Grinding Machine excels in manufacturing high-precision components. Its manual control system, robust spindle, and compact design offer reliable, repeatable results. The grinder accommodates workpieces up to 80 mm in diameter and 150 mm in length between supports, making it highly versatile for various applications requiring high accuracy and fine surface finishes.

Versatile Manual Operation and Superior Build

With manual hand and lever controls, operators maintain full command over the grinding process. The machines heavy-duty cast iron construction, automatic centralized lubrication, and low-vibration design ensure stability and long service life. Variable speed settings allow optimization for different workpiece materials, while the integral coolant system enhances both performance and safety during operation.

Advanced Surface Finish and Concentricity

Achieve industry-leading precision with up to 0.001 mm concentricity and surfaces as smooth as Ra 0.2 m. The adjustable carbide-tipped work rest and precision-ground slide way enable consistent results across batches. The choice of aluminium oxide or CBN wheels further extends the range of grinding applications, accommodating steel, alloy steel, and more. Suitable for exporters, manufacturers, and traders seeking Italian engineering excellence.

FAQs of Ghiringhelli Centerless Grinding Machine:

Q: How does the Ghiringhelli Centerless Grinding Machine ensure high precision and concentricity?

A: The machine is built with a precision-ground V-Flat table slide way, a high-rigidity spindle, and adjustable carbide-tipped work rests. Together with its precision bearings and robust construction, it consistently achieves up to 0.001 mm concentricity and ultra-fine surface finishes up to Ra 0.2 m.

Q: What applications are suitable for this centerless grinder?

A: This machine is ideal for centerless cylindrical grinding of precision components in the automotive, aerospace, and bearing industries. It is suited for grinding cast iron, steel, and alloy steel workpieces up to 80 mm in diameter and 150 mm in length.

Q: When should I choose plunge versus through-feed grinding on this machine?

A: Plunge grinding is recommended for components with complex shapes or multiple diameters, while through-feed grinding is best for simple cylindrical parts that require quick, continuous material removal. The Ghiringhelli machine supports both methods, depending on your production needs.

Q: Where can this machine be installed and what are its space requirements?

A: With dimensions of 2300 mm x 1400 mm x 1700 mm and a weight of approximately 3000 kg, the machine requires a stable industrial workshop floor with adequate space for operator access, maintenance, and coolant recirculation.

Q: What are the benefits of the integral coolant and automatic lubrication systems?

A: The integral filtered recirculation coolant system keeps grinding temperatures low and flushes away debris, preserving surface quality and tool life. The automatic centralized lubrication reduces maintenance, ensuring smooth operation and reducing wear over time.

Q: How is the working speed controlled, and what are the available speed options?

A: The grinder offers variable working speed, adjustable manually by the operator via hand and lever controls. The grinding wheel operates at 1750 RPM, with the spindle reaching up to 2000 RPM, allowing precise adaptation to material and job requirements.
