Holding workpieces between two flashlight lathes Holding the workpiece between two flashlights on the lathe is carried out by way of the edges of the workpiece with a fixed kepaĺa flashlight and a flashlight mounted on the loose head.
In addition to the flashlight of other assistive devices required in the work of a workpiece such as a carrier (lathe dog) and a carrier plate or a driving plate. Straight-tailed carrier and bent-tailed carrier
The carrier or lathe dog consists of the body, head and tail parts. The carrying body part has a oval shape with a hole in the middle. On the carrier's head is a clamp bolt whose edges are translucent to the hole in the carrying body. While the tail of the carrier is a straight shape there is also the shape of bent tails. Fig. 1 Straight tail carrier and twisted tail carrier The carrier is a tool that functions "carry " workpiece that is mounted between two flashlights so that the workpiece can spin while fertilizer. In the use of the end of the workpiece that will be inserted into the carrying hole, then the inserted piece of workpiece is pinned with the clamp bolt found on the carrier's head. When the bent-tailed carrier is used, it is inserted into the hole on the surface of the carrying plate. Whereas if the carrier is used straight tail, then the straight part of the tail is attached to the stem or pin found on the surface of the drive plate. Dead Flashlight and Rotary flashlight Flashlight is a tool in the lathe that serves to concentrate the edges of the workpiece that will be fertilizer. The flashlight has a taped body that can be inserted by fitting into a taping hole of the main spindle on a fixed head or loose head spindles.
The edge of the flashlight is a direct part supporting the workpiece, and is shaped in a pointed tapered with an angle of 60 °. Fig. 2 Dead Flashlight and Live flashlight There are two types of flashlight that are commonly used on lathes, which are dead flashlight or fixed flashlight and live flashlight (flashlight play). The dead flashlight is a flashlight that stays silent and does not spin along with the workpiece, while the live flashlight is a rotating flashlight along with the workpiece. Perforated carrier plate and stemware plate The perforated carrier plate and the stemware plate have the function of rotating the carrier (lathe dog) so that the workpiece attached and pinned by the carrier will be spun together with the spindle lathe. The carrier plate has a round flat shape such as a disc with holes or grooves on its surface. The carrier plates with these holes are used in pairs with the tail bearer Bemgkok, where on the use of the bent tail of the carrier are inserted into one of the holes on the carrier plate. Fig. 3 Perforated (grooved) carrying plate and carrying plate The stemmed plate also has a round flattened shape only the carrier plates of this type do not have holes such as the carrier plate perforated but have a stem or pin on its surface. The stemmed plate is used for pairing with a straight-tailed carrier, where inside the use of the carrier's straight tail will relate to the PIN or handle of the carrying plate so that if the carrying plate is spinning then the carrier will also Spinning. Holding a workpiece between two flashlights with carrier plates To hold the workpiece between the two flashlights, then both ends of the workpiece must have been given a flashlight hole where the ends of the two flashlights will take the workpiece through this flashlight hole. To make the flashlight can be done on the lathe or machine drill (drilling machine) by using Thunder Flashlight (centre drill). Holding a workpiece between two flashlights by using a perforated driving plate must be equipped with an immutable lathe dog with the following steps:
Put the flashlight off on a fixed head (head stock) and a rotary flashlight on the head tail.
Check the edges of the fixed head flashlight and the head off whether it is at the same time or not yet by sliding the head loose approaching the head anyway so that both ends of the flashlight meet. If not concentric then can be done adjustment to the head off.
Insert the end of the workpiece into the carrying hole flashlight and pinch it by rotating the clamp bolt on the carrier with the wrench.
Split both ends of the workpiece on the hole with a fixed head flashlight and head off.
In the second state of the workpiece is laid by the flashlight, put the carrier bent tail into one of the holes/grooves on the surface of the carrier plate.
Turn the hand wheel on the head off so that the workpiece is firmly placed by both flashlights, then locks the head off so that it doesn't shift back.
Tighten the binding nut on the carrier so that the workpiece is firmly pinned inside the carrier.
When not using a carrying plate that has holes, but using a drive plate that has a stalk or pin on its surface, the type of carrier used is not a bent-tailed carrier, but wear a carrier that Straight-tailed. While the workpiece holding measures between the two flashlights are the same as the above steps, except that the straight tail of the carrying is not inserted into the hole but arranged in order to connect (contact) with the carrier plate
