Technical Description

Things

The Blohm 204 grinder is a machine tool used for precision machining of flat and cylindrical surfaces of metal and similar materials. Its primary purpose is to achieve precise, high-quality surface finishes by removing small amounts of material. The machine is designed to ensure very tight tolerances and smooth surfaces, and is particularly useful for finishing and repairing mechanical components.

What is it for

Rectification is used for:

• Surface Finishing: Improve the surface finish of machined parts, ensuring a smooth, imperfection-free surface.
• Dimensional Accuracy: Maintain very tight tolerances in terms of size and shape of parts.
• Repairs and Refurbishments: Restore worn or damaged components to their original size and shape.

How to use it

Using the Blohm 204 grinder involves the following steps:

1. Machine Preparation:

   • Preliminary Check: Check the correct functioning of the main components, including the feed system and the spindle.
   • Setup: Mount the workpiece on the machine table and set the necessary angles and inclinations.

2. Rectification Operation:

   • Wheel Selection: Choose the right abrasive wheel for the workpiece material and the required finish.
   • Parameter Setting: Adjust the wheel speed and feed rate according to the specifications of the workpiece and material.
   • Starting Grinding: Start the machine and slide the abrasive wheel over the workpiece, making sure the workpiece is well positioned and secured.

3. Finish Control:

   • Measurement: Check the dimensions and quality of the treated surface to ensure they meet the required specifications.
   • Adjustments: Make any adjustments to the machine to improve the finish or correct any defects.

4. Maintenance and Cleaning:

   • Cleaning: Remove any residues of material and abrasive dust from the machine.
   • Inspection: Perform periodic checks to ensure that all parts are in good condition and working properly.

Materials used

The Blohm 204 grinder is suitable for working on a wide range of materials, including:

• Ferrous Metals: Steels, cast irons, etc.
• Non-Ferrous Metals: Aluminium, copper, brass.
• Special Alloys: Titanium alloys and other high strength alloys.

Types of adjustments

There are different types of grinders, each designed for specific applications:

1. Flat Grinding: Use an abrasive wheel to work flat surfaces, such as the Blohm 204.
2. Cylindrical Grinding: Intended for grinding external or internal cylindrical surfaces.
3. Bridge Grinding: Used to machine flat and cylindrical surfaces in a single operation.
4. Numerical Control Grinding: Advanced grinding using CNC to ensure high precision and accurate repeatability.

Maintenance of a used grinder

To keep a used grinder in good condition, it is essential:

1. Lubrication and Inspection: Check and maintain the lubrication system to prevent wear of moving components.
2. Alignment: Check and adjust the alignment of the sanding wheel and table to ensure accurate machining.
3. Cleaning: Clean the machine regularly to remove dust and debris accumulated during use.
4. Component Replacement: Periodically replace worn components such as abrasive wheels and cooling system filters.
5. Safety Check: Make sure all safety devices and guards are in good working order and working order.

Check the good condition of a used one

Before purchasing a used grinder, it is important:

1. Visual Inspection: Check the machine for signs of wear and damage. Check the table and guides for signs of excessive wear.
2. Operation Test: Turn on the machine and test the operation of the abrasive wheel, ensuring that there is no abnormal vibration or excessive noise.
3. Tolerance Control: Verify that the machine is able to maintain the tolerances required for the machining operations.
4. Documentation: Ensure the machine has all necessary documentation, including safety and compliance certifications.

Why it's better to buy used

Buying a used grinder, such as the Blohm 204, can be advantageous for several reasons:

1. Economical Savings: The cost of a used grinder is significantly lower than a new one.
2. Reliability and Proof: If well maintained, a used grinder can offer reliable and high-precision performance.
3. Immediate Availability: Used machines are often available immediately, reducing the waiting time for acquisition.
4. Resale Value: Used machines tend to retain a good resale value, allowing you to recover part of your investment.
5. Certifications: Many used machines are already certified and ready for use, ensuring compliance with safety regulations.

In conclusion, the Blohm 204 grinder is a versatile and precise machine tool, ideal for machining flat and cylindrical surfaces. Purchasing a used grinder can be a cost-effective option, provided it is well maintained and inspected to ensure optimal performance and operational safety.
