What is Power Tool's? ITI Online Note

 What is Power Tool's  

1- A power tool is a tool actuated by power source and mechanism other than manual labor used with hand tools for fastening bolts and nuts .

 Power wrench 

1- A power wrench is type of wrench that is powered by other means than human force.  

2- A typical power source is compressed air .  

3- There are two main types of power wrenches : 

i- Impact Wrenches and 

ii- Air ratchet or pneumatic ratchet wrenches.

Pneumatic torque wrench 

1- A pneumatic torque wrench is a primary torque multiplier or a gear box that is mated to a pneumatic air motor.

2- At the end of the gear box is a reaction device that is used to absorb the torque and allows the tool operator to use it with very little effort . 

2- The torque output is adjusted by controlling the air pressure . 

3- These planetary torque multiplier gearboxes have multiplication ratios up to 125 : 1 and are primarily used anywhere accurate torque is required on a nut and bolt , or where a stubborn nut needs to be removed . 

4- The pneumatic torque wrench is sometimes confused with a standard impact wrench due to their similar appearance . 

5- A pneumatic torque wrench is driven by continuous gearing and not by the hammers of an impacting wrench .

6- A pneumatic torque wrench has very little vibration and excellent repeatability and accuracy . 

7- The pneumatic torque wrench was first invented in Germany in the early 1980's .

8- Torque capabilities of pneumatic torque Wrenches range from 118 Nm , up to a maximum of 47600 Nm.

Maintenance of power tools 

1- A power tool is a tool actuated by power source and mechanism other than manual labor used with hand tools for fastening bolts and nuts. 

2- Properly storing power tools, performing maintenance as needed, and replacing machine parts will extend a tool's life to its full potential and deliver more value to its owner. 

Proper storage 

Our three guidelines for tool storage are: 

i- Store in an area protected from the elements (like moisture). 

ii- Store tools in a clean and organized space. 

iii- Store tools in a well-ventilated area. 

iv- Keeping tools out of the elements protects them from damage and wear.

v- A clean and organized storage space will promote safety, and keeping tools well-ventilated will help them run smoothly when it's time to pull them out of storage. 

vi- It might take a little extra time to put everything back in place at the end of the day or completion of a project, but storing tools the right way will always be worth the effort. 

Care and maintenance of Power Tool 

1- Before being stored, most power tools can use a little cleaning and a couple of quick checks for damage or other problems. 

2- Here's some maintenance tips for keeping those tools in good shape. 

3- Use a tooth brush and a soft cloth to wipe debris from power tool casings before storage. 

4- If available, use an compressor to clean out power tool vents. A little air will go a long way. 

5- When a machine or tool can breathe more. It will run cooler and wear more slowly. 

6- Lubricate power tool parts that need to be lubricated.

7- Check the parts that hold a tool together, screws and other fasteners. Tighten up anything that might have been shaken loose during operation. 

8- Electrical cords should be checked with each use of a power tool. 

9- Keep blades and other cutting accessories sharp. 

10- Check bits and other accessories for wear and damage.
