Visual description of the wheel grinder

The grinder has a compact and robust machine body, built in metal material resistant to wear and impacts. Its structure is designed to ensure stability during use, reducing unwanted vibrations and increasing machining precision. The 150 mm grinding wheels, one on each side, are protected by metal guards which guarantee the safety of the operator and the protection of the machine itself. The frontally positioned switch allows convenient access for turning on and off, with a safety function against accidental restarts.

Main mechanical characteristics

• Motor: Single phase, powered by 220V, 50Hz.
• Power: Generally around 370W, designed to guarantee constant torque.
• Speed: 2880 rpm, ideal for quick and precise work.
• Mole:
  • Diameter: 150mm.
  • Thickness: 20 mm (compatible with standard and special grinding wheels).
  • Center hole: 16mm for secure and easy mounting.
• Weight: About 6-8kg, easy to carry and install.

How to use the grinder wheel

1. Preparation: Make sure the grinder is mounted on a stable surface or dedicated base. Check that the grinding wheels are well secured and in good condition.
2. Startup: Connect the power and turn on the switch. The machine quickly reaches the operating speed of 2880 rpm.
3. Processing:
   • The left wheel is usually used for roughing, while the right one is ideal for finishing.
   • Maintain moderate pressure on the workpiece to achieve an even finish.
4. Stopping: Turn off the machine using the switch and wait for the grinding wheels to completely stop before proceeding with cleaning or replacement.

Compatible accessories

• Dedicated bases: For greater stability during use.
• Special abrasive wheels: Suitable for working hard materials such as stainless steel or light alloys.
• Additional protections: Such as safety masks to protect the operator from splinters and sparks.

Formulas to calculate the optimal use parameters

To ensure the best performance, it is useful to calculate the peripheral speed of the grinding wheel :

$$V$$

Where:

• VpV_p $V$ p ​:
• DD $D$ : Diameter of the grinding wheel (m).
• nn $n$ : Rotation speed (rpm).

With a 150 mm wheel and a speed of 2880 rpm (48 rpm), the peripheral speed is approximately 22.6 m/s , ideal for a wide range of processes.

Workable materials

The wheel grinder is designed to process various materials, including:

• Steel and ferrous alloys.
• Aluminum and light metals.
• Hardwood and other composite materials (with dedicated wheels).

Recommended maintenance

• Regular inspection of grinding wheels: Check for signs of wear and replace them when necessary.
• Cleaning: Remove dust and debris from the machine body and protective covers.
• Bearing check: Lubricate as necessary to keep the grinding wheels moving smoothly.
• Checking the switch: Make sure it is working properly, especially the anti-restart function.

Safety regulations

If the machine does not have the CE mark, it is possible to adapt it to current regulations with:

• Installation of a certified electrical panel.
• Addition of operator protections.
• Checking the earthing and electrical safety devices.

Always use personal protective equipment such as gloves, glasses and ear muffs.

How to evaluate a good used one

To understand if a used wheel grinder is of quality:

1. Check the condition of the grinding wheels and the motor.
2. Check that there is no excessive vibration during use.
3. Ask for prior maintenance documentation, if available.

Sectors of use

This grinder is mainly used in:

• Mechanical workshops.
• Craft and hobby sector.
• Metallic and light carpentry workshops.

Why buy a used grinder

Buying a used wheel grinder means saving without sacrificing quality. Thanks to the robustness and longevity of these machines, even a used model like this guarantees reliable performance for years. Don't miss this opportunity: the wheel grinder is a smart investment for your work!
