It relates to the orientation of the hook (the part under the bed that catches the top thread to create the lock stitch) to the needle. Horizontal machines often have a 'fixed' bobbin case that the user doesn't remove, and utilize a drop-in type of bobbin, whereas vertical machines have removable bobbin cases that the user must insert the bobbin into, then insert the filled bobbin case into the machine.
Horizontal bobbins usually hold a lot more thread and make it easier to replace the bobbin without having to remove the work, therefore you will commonly find this type in industrial applications.
Machines come with either a "horizontal bobbin" or a "vertical bobbin."
The horizontal bobbin is normally a "drop in" bobbin -- when you slide the needle plate over, you'll see a circular depression in which you "drop" the bobbin. There's normally an angled slot you'll pull the bobbin thread through.
A vertical bobbin requires that you use a bobbin case. You insert the threaded bobbin in the case, pull the thread through an angled slot in the case, then press the bobbin case into a slot under the needle plate. There's usually some sort of door covering this slot -- although older machines like Singer 301s and Featherweights have the bobbin case simply sitting underneath the bed.
Dumpty level can be used only for vertical measurements while a theodolite functions in both horizontal and vertical measurements.
VERTICAL DISTRIBUTION REFERS TO THE DISTRIBUTION OF THE DIFFERENT LAYERS IN A MULTITHREAD ARCHITECTURES ACCROSS MULTIPLE MACHINES.In princeiple, each layer is implemented on a different machine. horizontal machine deals with distribution of a single layer accross multiple machines such as distibuting a single database
Horizontal and vertical milling machine.
Horizontal and vertical milling machine.
There are two types shaper machine they are horizontal and vertical
Justify the using of the horizontal milling machine for making the baseplate
A "horizontal maching center" has a horizontal spindle. With a horizontal spindle, tools stick out the side of the tool holder and cut across the side of a part (workpiece). Horizontal machining centers are far more expensive than equivalent capacity vertical machines, but have several advantages. Usually the tool holder of a horizontal machine is more ridgid. Also,when machining the side of a part, metal chips fall out of the area being cut, leaving an uncluttered cutting area.A "vertical machining center" has a vertical spindle. With a vertical spindle, tools stick straight down from the tool holder, and often cut across the top of a part. One disadvantage of vertical machining is that when tools cut across the top of a part, the metal shavings, called "chips," often pile up around the tool and interfere with the cutting action. However, vertical machining centers are more common, primarily because they are less expensive than equivalent capacity horizontal machines.
Vertical milling machine and horizontal milling comparison, the main difference is the spindle vertical layout, except for different spindle arrangement, table can move up and down, vertical milling cutter with relatively flexible, wider scope. Use cutter, cutter support, drill and so on. Can keyway milling, milling flat and boring.
what is the difference between drive and machine
Horizontal or vertical gear shaping machines, they can also be made on slotting machines.
A shaper is a reciprocating machine tool in which the ram moves the cutting towel backwards and forwards. A shaper is intended to produce flat surfaces. A planer is used to produce horizontal, vertical or inclined flat surfaces. A planer is used to work on heavy and large work pieces that cannot be accommodated on the table of a shaper. A slotter is also called a vertical shaper. The difference between a shaper and a slotter is the direction of the cutting action of the tools.
There is no difference between a turning machine and a lathe. They are two names for the same kind of machine
