HARDWARE REVIEW: PRECISION TOOLS

Part of every job is to use different software and hardware tools. Unfortunately, some of these software and hardware are doing us more damage than good, and some are so useful that you cannot work without them. In this article series, I will discuss the software and hardware I use as a mechanical design engineer. In this article, I will talk about the precision tools I use for precise work.

Introduction

In order for a mechanical design engineer to perform his job well, one must have a lot of “toys.” When working with the parts that require precise handling or special attention to detail, I use different tools like precision screwdrivers, scalpels, tweezers, files, etc. These tools are not expensive, but they are quite useful in everyday work.

Precision screwdriver set

When working with small electronics or small parts, you need a precision screwdriver set. This set is basically a collection of different bits for different screw types. You can, of course, purchase the expensive professional set, but if you use these tools periodically, a standard set will do the trick. I have purchased a set I also use for disassembling when cleaning my PC and laptops. You can find online different inexpensive sets that will fit your needs. I am using this set: Padarsey 79 in 1 Precision Screwdriver Set.

Cutting mat and scalpel set

For cutting different foils, labels, clay (for prototyping), or cleaning 3D printed parts, you need a good set of scalpels. Furthermore, buy a cutting mat to prevent any damage on your desk and keep your fingers safe at all times (talking from experience). Here is the cutting mat and scalpel set that I am using. Also, you could think of buying a longer steel ruler for long cuts and lines.

Precision Tweezers Set

A good tweezer set is necessary for small parts, foils, labels, and small connector assembly. There are different types of tweezers, and each type is better for something than the other. Therefore, I would suggest buying a set of different types, so you have a good choice depending on your need. I purchased 14 tweezers set for a small price, and they are more than enough for my needs.

Small File Set

If you are making any prototypes by hand, you should have a small set of files for cleaning, finishing, and smoothening any rough and imperfect surfaces and edges. This is especially useful when you have complex geometry and cannot reach the surfaces and edges with the standard deburring or rotary tool. For a small amount of money, you can get different sets with different file types that will give you a range of possibilities for the final surface finish. Depending on your needs and the size of your parts, you can find a file set that will fit your need.

Deburring tool

Similar to the files, you can use deburring tool for removing burs on the edges. I would suggest getting a deburring tool because you can relatively quickly clean burs on long edges resulting in a nice and clean cut.

Rotary Tool

One of the most valuable tools for creating prototypes is a rotary tool. Some of you may refer to it as an engraving tool, but this is much more. For example, if you have a 3D printed part with the support structure, you can use a rotary tool to remove any leftover imperfections on the surface with the rotary tool. By changing the bit on the rotary tool, you could cut, grind and polish the surface in question.

There is a wide choice of different tools on the market, and you can choose whatever will fit your needs. Whatever you decide to buy, I suggest you buy at least one cordless rotary tool like Hardell’s one. They are usually smaller and easier to handle, giving you certain flexibility that the ones with cable cannot.

Conclusion

As a mechanical design engineer, having a proper tool is extremely important. You should invest some time in researching what types of tools would fit your needs and ask your company to buy them. The right tools will save you time, and time is money. That is always a good argument when asking for something from the company.
