Technical Description

Things

The Blohm 204 grinding is a machine tool used to perform precision machining on flat and cylindrical surfaces of metal pieces and similar materials. Its main purpose is to obtain precise, high-quality surface finishes by removing small amounts of material. The machine is designed to guarantee very tight tolerances and smooth surfaces, and is particularly useful in finishing and repairing mechanical components.

What is it for

Rectification is used for:

• Surface Finish: Improve the surface finish of machined pieces, ensuring a smooth surface free of imperfections.
• Dimensional Accuracy: Respect very tight tolerances in terms of size and shape of the pieces.
• Repairs and Regenerations: Restore the original size and shape of worn or damaged components.

How to use it

The use of Blohm 204 grinding 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. Grinding Operation:

   • Wheel Selection: Choose the appropriate abrasive wheel for the workpiece material and 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 piece, making sure the piece is well positioned and secured.

3. Finish Control:

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

4. Maintenance and Cleaning:

   • Cleaning: Remove residual material and abrasive dust from the machine.
   • Inspection: Carry out periodic checks to ensure that all parts are in good condition and functioning properly.

Materials used

The Blohm 204 grinding 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 machine 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 grinding machine

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

1. Lubrication and Control: Check and maintain the lubrication system to prevent wear of moving components.
2. Alignment: Check and adjust the alignment of the abrasive wheel and table to ensure precise processing.
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 that all safety devices and protections are in good condition and functioning.

Check the good condition of a used one

Before purchasing a used grinding machine, 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, making sure there are no abnormal vibrations or excessive noise.
3. Tolerance control: Check that the machine is able to maintain the tolerances required for machining.
4. Documentation: Make sure 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. Economic Savings: The cost of a used grinding machine is significantly lower than a new one.
2. Reliability and Proof: If well maintained, a used grinding machine can offer reliable, high-precision performance.
3. Immediate Availability: Used machines are often available immediately, reducing waiting times for acquisition.
4. Resale Value: Used machines tend to maintain 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 grinding machine is a versatile and precise machine tool, ideal for machining flat and cylindrical surfaces. Purchasing a used grinding machine can represent an advantageous economic choice, provided that it is well maintained and checked to ensure optimal performance and operational safety.
