What Is Angle Plate?
The angle plate is made by two plates machining at an angle of 90 degrees. Since the plates join at a particular angle, it is called an angle plate. It is used to clamp the job, supporting it at 90 degrees.
The edges and ends of the angle plates are also produced at 90 degrees by machining. The part of the angle plate that is not in the ribs of that part is made for proper grip and prevents any deformity. The ribs support two plates of the angle plate.
Angle plates are mainly made of G.C.I (Granular Cast Iron). The jobs are mounted using angle plates for both measuring and marking.
The shape of an angle plate is specified using its length, width, and height. Depending on the size of the angle plates, they are numbered from 1 to 10. Nos. 1 to 6 is the first-class angle plate, and 7 to 10 is the second class angle plate.
The 1st-grade angle plate is very well-grounded and is of high quality. 1st Grade angle plates are used in the tool room as very precise machining, and marking can be done using 1st-grade angle plates.
Second-class angle plates are of lower quality than first-class angle plates. They are used in machine shops or workshops.
Apart from the 1st-grade angle plate and 2nd-grade angle plate, a precision angle plate is also available for checkings the quality of 1st grade & 2nd-grade angle plates.
Types of Angle Plates:
#1. Plain or Solid Angle Plate
These angle plates are named plain angles plates because both plates, which are placed at 90 degrees in these angles plate, are completely plane. There are no slots on this plate. These are the most commonly used angle plates of all different types.
These plane angle plates have ribs to prevent the angle plates from becoming deformed or deformed. These angles plate are smaller in size than other angles plate.
#2. Slotted Angle Plate
Slated angles are cut slots or grooves between the plates in the plate. They are larger in size than a plain angle plate. The slots are cut into a slotted angle plate so that we can fasten a job in it using a nut and bolt. Clamping bolts are attached in slots on the top plane surface of the slotted angle plates.
The bottom side of the slotted angles plate can also be properly glued with the machine table. It is also used to fasten, support, and mark the workpiece.
For marking & machining, this type of angle plate can be rotated up to 90 degrees. This slotted angles plate can be used in lathe, shaper, grinding machines.
#3. Adjustable Angle Plate or Swivel Base Angles Plate
In this type of angle plate, angles between two plates are adjustable, i.e., we can change the angle between the two plates as per our requirements.
In this type of angle plate, the two plates are not machined with each other. They are separated from each other. One plate serves as the base, and the other plate can move and change its angle relative to the first plate. Both plates are slated in an adjustable angle plate.
One plate has graduation marking of different angles so that the tilt angle can be detected with respect to the other surface, & we can set the plates at an angle that is necessary. There are nut bolts to lock the two plates at any angle.
These angle plates are used where we have to do precise machining or machining at a specific angle other than 90 degrees.
Box Angle Plate of Angle Plate:
It is called a box angles plate because its structure is like a box. This type of angle plate consists of six plates alternately at 90 degrees. The use of a box angle plate is similar to the use of angle plates indicated above.
There are slots in each of the six plates on this angle plate. Since there are slots on each side, the job can be properly fastened on either side using a nut and bolt.
After camping or setting the workpiece or job, the job can be rotated with a box angle plate, i.e., we can easily rotate the box to change the orientation of the job for various operations like drilling, marking, etc. This is a very useful feature—this box angle plate makes various processes very easy.
All the planes in this box angle plate are joined by machining them at 90 degrees so that the angle has precision. Box angle plates are used in large machines such as radial drilling machines for clamping workpieces.
Swivel Angle Plates of Angle Plate:
Swivel angle plates ensure that work can be set quickly and correctly at any angle with these adjustable swivel angle plates. They are graduated to set 0 – 90 ° and can be easily adjusted manually and locked to the adjusted position via two locking nuts. To establish the objectives, a degree scale, a minimum of one-degree reading, is graduated on the boss itself. This ensures better setting accuracy.
Swivel angles plates are offered in the following sizes: Tilting angle (0 ° -90º)
