Types of Vertical Tool Grinders

Strong, effective, and a force to...

Vertical tool grinders have become popular in many machining and industrial settings. With each passing day, the need for more inventions in our machinery industry has created a large market share.

Vertical tool grinders are essential for adequately sharpening tools and reducing mishaps in manufacturing companies. They are practical, versatile, and space-saving—paving the way for safer and faster production processes.

The working principle of a vertical tool grinder is relatively simple. Vertical grinders have an upright spindle on which grinding wheels are mounted. The tool or workpiece is then held in fixtures or jigs and rotated against the grinding wheel, which removes material from the surface to be ground.

Vertical tool grinders can be categorized into two main types based on their power source: electric vertical tool grinders and pneumatic vertical tool grinders.

• ELECTRIC VERTICAL TOOL GRINDER: Electric vertical grinders are powered by electricity. They are usually plugged into an electric socket before being switched on. Electric grinders are more prominent, but their heavy-duty motors ensure they can handle more tools and more quality.
• AIR VERTICAL TOOL GRINDER: As the name suggests, pneumatic vertical grinders are powered by air pressure. They tend to be smaller and lighter than their electric counterparts, making them easier to maneuver. In addition to this, they produce less heat owing to their air-powered motors. Another feature that makes pneumatic vertical grinders better than electric grinders is that they have low kickbacks. This makes them safer options for unfamiliar tool operators. However, the operator needs a compressor for the grinder to function. This may limit its usage as the compressor may not be easily portable.

On the other hand, vertical tool grinders can also be categorized based on the grinding wheels used.

• CUP GRINDING WHEEL: Normally used for heavy material removal operations, cup grinding wheels feature a wide face and a shallow crown to cover more surface area. This allows for grasping more features to be ground. They are quite popular in foundries and metalworking facilities.
• FLOOR GRINDING WHEELS: As the name suggests, grinding wheels are specifically used for floor grinders. They have a flat face and are often used to level, remove coatings, and polish concrete floors.
• ANGLED GRINDING WHEELS: Due to their already known features and specifications, angled grinding wheels are used for more detailed work on irregular and intricate parts.

Lastly, CNC vertical tool grinders might use computer numerically controlled systems to automate tool sharpening processes. These grinders are more expensive, but their increased automation and precision can justify the higher costs in some applications.

Maintenance of vertical tool grinders

Proper maintenance of the tool grinder machine helps it maintain its optimum performance and prolongs its lifespan. Most manufacturers recommend routine inspections to identify any signs of damage, wearing out, or irregularities that may signify underlying issues. They advise taking note of the condition of parts like belts, grinding wheels, bearings, and pulleys, among others, checking for any signs of leaks, alignment issues, or cracks.

Vertical tool grinders can efficiently operate with proper lubrication for their moving parts and bearings. Regularly cleaning the tool grinder is also crucial for maintaining its performance and efficiency. It prevents the building up of residues, dust, debris, and metal shavings that can interfere with the functioning of the machine.

Some more maintenance practices include:

• Timely repairs: If an inspected part is damaged or worn out, a prompt repair or replacement is necessary to avoid more damages or compromising the quality of the final product.
• Electrical maintenance: It is essential to handle the electrical connections with care and avoid exposing them to moisture. Checking the grinding tool's power supply and preventing overloading helps in maintaining its functionality. Seek assistance from a qualified technician in case of any electrical faults.
• Regular wheel dressing: This helps maintain the grinding wheels' shape and roughness. Wheel-dressing tools are used to remove any clogging or deposits on the surface of the wheel.
• Airflow maintenance: Keeping proper airflow is crucial in preventing overheating of the grinder as a result of high-speed rotations. Users can ensure suitable air circulation by regularly cleaning the machines and avoiding any blockage.
• Safe operations: Proper handling and safe operations of the grinder tool can greatly minimize the risks of damages and injuries. It is important to wear proper protective equipment such as goggles, masks, ear protection, and others. Ensuring suitable tool grounding and electrical insulation can also achieve safe operation.

With the right maintenance practices over time, vertical tool grinders may need major repairs or breakdowns, saving users a lot of costs in the long run.

Scenarios of vertical tool grinders

The vertical tool grinder can be used in different industries and manufacturing sectors. Its usage application depends on the type of tools people grind with it.

• Metalworking Industries: Every metalworking industry uses tool grinders, even vertically. They are used to sharpen cutting tools, drills, dies, blades, and other equipment used in the metalwork industry.
