Drill Holding Devices

Drill Holding Devices Points : Drill Holding Devices, Angle plate, Drill vise, V-Block, Jackscrew, Holding Odd shaped work, Holding Round, Step block, Parallels ,Holding flat work, Use of Clamp Toward make drill securely fixed holding of drill with job in a work holding device should be make certain. Drill is tighten to drill chuck with the job is tighten to drill press table directly or using a proper tool. After position the work at its correct place, drill press table is clamp to the column. But the job springs or move through drilling, drill might turn and break the job might be thrown as of table and big injury may results to machinist with to machine. Various devices and process of support and holding work on drill press are explained under.
1. Angle plate
2. Drill vise
3. V-Block
4. Jackscrew
5. Holding Odd shaped work
6. Holding Round
7. Step block
8. Parallels
9. Holding flat work
10. Use of Clamp
1. Angle plate Job is at times clamped to an angle plate, also known a toolmaker's knee, which is clamp to drill press table. Such work generally cannot be held or else on drill press table whilst it is drilling.
2. Drill vise Drill vise is clamp to drill press table with the work is held in vise. Drill vise is prepared by flat jaws have V grooves straight as well as upright. V grooves are useful in holding round job in flat jaws.
3. V-Block V-block obtains its name as of its V shape. Angle of V is generally 90° V blocks are use to hold around job. They are prepared with or with no Clamp.
4. Jackscrew Jackscrew, also identified as a planer jack ranges in height as of 2" upward. It might be use for level or supporting odd shaped job.
5. Holding Odd shaped work Special holding tools can be required to hold odd shaped work. A few works might be fastened to an angle plate. Odd shaped work held by U-clamps with modifiable bolts.
6. Holding Round Work Round work such as rods can be held in V-Blocks.
7. Step block Step block is use to hold up with block up one end of a strap clamp. This levels clamp so that together ends are equal height as of the table.
8. Parallels Parallels are strips of cast iron or steel by opposed sides parallel. They come in pair precisely a like in size. Parallels are use in level or jamming up job. A parallel is pace below each end of work.
9. Holding flat work Flat work such as a plate, might be clamped to table. C-clamp must be on left side of table with the body of clamp must be at the back job. Drill be able to kept as of cutting into table by placing a portion of wood below the work, by setting work so that drill will go by keen on hole in center of table or by using parallels.
10. Use of Clamp Clamp is an instrument use for holding piece of work. Kind of clamps are:
i. C-Clamp
ii. Parallel clamp
iii. Strap Clamps
i. C-Clamp C-clamp shape similar to alphabet C is calculated by most distance it can be open among the haw with the end of screw. It is prepared in any sizes and is functional for clamping work to drill press table.
ii. Parallel clamp Parallel clamp is also known as Toolmaker clamp or Machinist's clamp, might be use to clamp work in place for drilling. Its size is calculated as of its greatest opening.
iii. Strap Clamps Strap clamp are use to hold down the job. Some types of strap clamps are as below. a. Double finger clamp
b. Finger clamp
c. Screw heel clamp
d. Goose neck clamp
e. U-Clamp
