We were discussing Plumbing tools and their use and Carpentry tools and their use in our previous post. Today we will try to understand the term Carpentry machines and their importance with the help of this post.Â
We can define the term carpentry as the process of making wooden components. For example, floors, roots, partitions, windows and doors.Â
Carpentry Machines
Carpentry machines are basically used for mass production of parts or components. Let us see here now the normally used carpentry machines as described below in the following section.Â
Wood Turning LatheÂ
Let us see a wood turning lathe, as displayed here in the following figure, is the most important and common machine used in a carpentry shop.Â
Figure : Wood Turning LatheÂ
Now, you might be thinking why we need to study about such a machine, So its importance in a carpentry shop will let you know the need for understanding about the wood turning lathe machine.Â
We must understand that a wood turning lathe machine is used for manufacturing the spherical, cylindrical and tapered shape parts or products.Â
A wood turning lathe machine will have following important parts associated with it, as mentioned below.Â
Main MotorÂ
Cast Iron bodyÂ
Cone pulley systemÂ
SpindleÂ
Tool pestÂ
Head stock,Â
Live and dead centersÂ
speed control devices Â
Lubrication / Oil coolant systemÂ
In a wood turning lathe machine, the workpiece will be held in between its two centers. The tool will be held in the tool post.
The workpiece will be rotated in between the two centers. The cutting tool will be passed towards the work and will remove the material and produce the desired shape and size as per design requirement of the components.Â
Circular Saw
We can see the circular saw machine in the following figure. Once you observe the circular saw, you will easily understand why we need to use this machine and what is the importance of a circular saw machine in a carpentry machine shop.Â

So, let's see…
A circular saw is a carpentry machine which is basically used for ripping, cross cutting, grooving, leveling and rebating.Â
There will be following parts associated with the circular saw machine as mentioned below.Â
A circular cutting bladeÂ
Main MotorÂ
Cast iron table
Saw guideÂ
GuidewaysÂ
Elevating hand wheelÂ
Tilting hand wheelÂ
Lubrication / Oil coolant systemÂ
In circular saws machines, the workpiece will be held on the table. Then the work is moved against the circular saw in order to execute the desired operations. The circular saw hand wheel will be used in order to adjust the height of the saw above the surface of the table.Â
We must note here that the table could be tilted up to 45 degrees for executing the cutting operation with different angles. It could be considered as an ideal machine for mass production. The size of the circular saw machine will be dependent over the size of the saw blade.Â
Band Saw
We can see the wood band saw machine in the following figure. Â
Figure : Wood band saw machine Â
So, let's see…Â
A band saw machine is basically used for following functions as mentioned belowÂ
LevelingÂ
Cross cuttingÂ
Grooving
MiteringÂ
RebatingÂ
Let us see the various important parts of a band saw machine as mentioned belowÂ
Main MotorÂ
Two wheels having an equal diameterÂ
Steel cutting blade with having teeth on itÂ
Arrangement for tensioning of this steel cutting blade
Saw guiderÂ
Wheel guardÂ
Frame tableÂ
Saw tensionÂ
Lubrication / Oil coolant systemÂ
The band saw blade will travel over the rims of two wheels having an equal diameter. The blade width will vary in the range of 6 to 25 mm and the thickness will be in the range of approximately 1 to 2 mm.Â
