Pencil grinders rotate carbide burs and mounted points to remove light material in detailed grinding, sculpting, deburring, and polishing tasks. Their slim, compact body allows for fine control and access to tight spaces, allowing them to perform intricate, precise work. They are ideal for light deburring, deflashing, surface preparation, cleaning, and finishing with the appropriate abrasive stones, abrasive-mounted wheels and points, molded abrasives, and carbide burrs. Final cleaning, die and mold polishing, hole finishing, and contour blending are all standard applications. Because these air-powered tools have few moving parts, they run cool and have a long lifespan. When buying a pneumatic pencil grinder, you should keep a few things in mind. These include safety precautions, types, discs, and speed. Knowing these things before purchasing will help you to get the most out of your grinder. Keep reading to find out more.
Safety Precautions
Before using a pneumatic pencil grinder, it is essential to take the proper safety precautions. First, wear appropriate PPE to protect yourself from the sharp edges and shards of metal. In addition, it is essential to wear eye protection. Using the correct tools is also important. When using a grinder, ensure it is equipped with suitable discs and the right feet. Finally, always pay close attention while working and remove loose clothing or jewelry.
Another essential safety precaution is to wear safety glasses and hearing protection. Using the wrong air pressure can cause flying debris and damage to the ears. Always wear eye and hearing protection while using pneumatic tools.
Types
When deciding which pneumatic pencil grinder to purchase, you should consider the type of job that you will be doing with it. Pencil grinders come with various attachments that can increase their versatility. Some of them have extra-fine controls. Choose a pencil grinder with extra-fine control to make a precise cut.
A high-speed pneumatic pencil grinder is designed for high-speed grinding. Its high-speed motor rotates a collet with a diameter of 1/8″. It weighs less than a pound and has a rear exhaust. Its body diameter ranges from 16 to 19 mm. It is ideal for polishing metals or removing an electroplating layer.
Speed
Choosing the right speed for your pencil grinder is critical in achieving the best results. Many models are designed for grinding pencils at a single speed, but some are more versatile, and you can change the speed to match your needs. In addition to the standard settings, attachments are also designed for more powerful work. These include burs and mounting points.
Discs
Pneumatic pencil grinder discs have a variety of uses. They can be used for cutting, polishing, and sanding purposes. A typical disc size will be a medium or coarse grit. Some discs are specially designed for specific purposes. For instance, there are diamond cut-off discs for cutting metals. There are also discs with polishing pads for buffing.
There are several differences in grit and hardness, and it is essential to read the instructions before using the machine. You should also ensure that you use the correct disc for the material you’re working on.
