SURFACE GRINDING PERFECT #wokochannel #pedaganglucu #tukangteknik

Summary

This video tutorial provides a detailed guide on operating a surface grinding machine, specifically the Perfect PF618M model. It covers crucial aspects such as setting up the machine, locking the nonius, balancing the grinding wheel, and performing maintenance. The script explains how to adjust the grinding parameters for different materials like cast iron, steel, and stainless steel. It also emphasizes the importance of precision during the grinding process and demonstrates the necessary actions for optimal performance, including using the cooling and lubrication systems. The video aims to educate users on safe, efficient surface grinding techniques.

Takeaways

• 😀 The surface grinding machine (Perfect PF618M) is used for grinding and finishing metal surfaces, specifically for smoothing, not reducing the size of materials.
• 😀 To operate the machine, first power it on and slowly raise the grinding wheel until it touches the material, producing a spark. This signals the correct position.
• 😀 The grinding wheel must be balanced to prevent wobbling and ensure proper operation during the grinding process.
• 😀 Surface grinding is only for finishing purposes, and it should not be used to remove significant material (e.g., reducing a 5cm piece to 4cm).
• 😀 The machine allows for precise adjustments using the nonius, with one full rotation corresponding to 2mm of adjustment.
• 😀 Different metals require different feed rates. For example, soft steel uses a feed rate of 0.005-0.01mm, while stainless steel requires 0.03-0.05mm.
• 😀 The table of the machine moves forward and backward with the help of a handle, while the grinding wheel's vertical height is adjusted separately.
• 😀 When operating the machine, the workpiece should be fed from left to right to ensure smooth grinding and avoid any errors.
• 😀 The machine also has a water pump and a blower system to keep the process clean by preventing debris from spreading during operation.
• 😀 The manual magnetic chuck is used for securing the workpiece in place, although it's not used in this particular machine model due to its manual operation.
• 😀 The grinding process involves regular lubrication of the machine's moving parts to ensure smooth and efficient operation.

Q & A

What is the primary purpose of the Perfect PF618M Surface Grinding Machine?

The primary purpose of the Perfect PF618M Surface Grinding Machine is to perform precision surface grinding, which involves smoothing and polishing metal surfaces, rather than removing large amounts of material.

How do you start the grinding process on this machine?

To start the grinding process, first power on the machine. Then, slowly raise the grinding wheel until it makes contact with the workpiece, at which point you will see sparks. After this, lock the nonius scale to the zero point.

What does the nonius scale do on the grinding machine?

The nonius scale allows for fine adjustments to the height of the grinding wheel. Each full rotation of the adjustment handle moves the wheel by 2 mm, and each strip on the scale represents a 0.1 mm change.

Why is it important to balance the grinding wheel before use?

Balancing the grinding wheel is crucial to prevent vibrations, which can negatively affect the quality of the grinding finish. A balanced wheel ensures smooth operation and a high-quality surface finish.

What is the recommended direction for moving the workpiece during grinding?

The workpiece should be moved from left to right during the grinding process. This ensures optimal grinding and helps in controlling the finish.

What should the operator do to ensure the grinding process doesn't overheat the workpiece?

The operator should ensure that the coolant system is working properly. Both the coolant pump and blower should be activated to prevent overheating, and water or oil should be applied to the workpiece to keep it cool during grinding.

How is the table movement controlled during grinding?

The table movement is controlled using the handle, which allows the operator to move the workpiece forward and backward. The vertical movement of the wheel is controlled by a separate handle for raising and lowering the wheel.

What role does the magnetic chuck play in the grinding process?

The magnetic chuck holds the workpiece securely in place during grinding. It is important to ensure that the chuck is properly activated when required to prevent the workpiece from shifting during the operation.

What happens if the nonius scale is not set correctly before grinding?

If the nonius scale is not set correctly, the grinding wheel may not be at the correct height, which can lead to improper grinding, either too shallow or too deep, affecting the precision and finish of the workpiece.

What is the function of the emergency button on the machine?

The emergency button is used to immediately stop all functions of the machine in case of an emergency or malfunction. Pressing this button cuts off power to the machine, halting all operations for safety.
