Machine Tools
Machine tools is the term used for the machinery used in engineering workshop for manufacturing metal products and parts. These machines include: Lathes, milling machines, CNC lathes and machine centers, Horizontal and vertical boring mills, slotting machines, shapers, radial arm drilling machines, gear cutters and grinders, power saws, etc.

What is the difference brtween vertical milling machine and horizontal milling machine?
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.

Why this cnc machines are used?
the cnc technology is applicable for high accuracy machining and high speed machining,it si more efficient than the conventional methods like lathe,driller,etc..by the application of cnc the production time can be reduced and there by increase the productivity and profit .
tool post is used to handle the tool on the lathe machine
How pass line is calculated in hot rolling mill?
Rolling schedule is the time sequence of passes of rolled piece through the mill respecting many constrains and limitations such as:
- * Limit separating force
- * Limit rolling torque
- * Bite angle
- * Flatness limits
- * Metallurgical limits
- * Specific limits(length of delay table, etc.)
If all constrains are fulfilled and rolling schedule gives maximum productivity (minimum production time) and the desired product and its specifications are obtained, we can speak about optimum rolling schedule.
What are the Cutting tools on Lathe machine?
Now a days verities of materials are using for making lathe cutting tools. In earlier days Hardened high carbon steelswere used. High Speed Steel (HSS) came next to HCS. Ordinary carbide inserts of different grades came after HSS. Coated carbide inserts of various grades suitable for machining different metals and alloys are predominant now. Ceramic and diamond inserts are the latest cutting tool materials using for the machining of materials having very high hardness.
How do you make an inside taper on a lathe?
These are the basic steps used to machine an inside taper on a lathe:
- The required boring bar is inserted into the tool post and the work piece is bored to the smaller size of the taper
- The tool post is set to the required degrees (the boring bar angled towards the work piece)
- Using the tool post slide (or compact slide) hand wheel, it is turned in a counter-clockwise direction to allow enough travel over the entire taper length
- Now the tool tip is moved towards the edge of the workpiece bore with the carriage and cross slide hand wheels
- At this point the tool post slide hand wheel is used and turned in a clockwise direction to start cutting the taper a few millimeters at a time until the taper is roughly 2mm undersize
- Mechanical blue is put onto the mating test piece then the test piece is inserted it into the taper to check if the degrees match. Where there is more rubbing, the tool post degrees are slightly adjusted by using a dial indicator and a note of the adjusted amount set is made.
- Another cut is made and the taper is re-tested using the same method. If it requires further adjustment, the process of adjusting the angle with the dial indicator is repeated and. The dial indicator is placed in the exact same spot as before.
- When the taper matches the test piece, the final cuts are done with a very smooth, continuous motion on the tool post slide hand wheel.
- The workpiece may be retested with test piece after every cut to ensure precision of the final piece.
The above method is just a basic explanation of how the operation is achieved. Operating a lathe without proper training is not recommended and could lead to serious injury!
Why cast iron used for bed of lathe?
Any solid material that is capable of cutting ferrous metals are used, but if the family is the most iron.
<><><>
Cast iron is less prone to warping than other metals.
This refers not to the machining of cast iron, but the use of cast iron as the bed of the lathe.
Yes, more housing is made of cast iron industrial machines.
Because iron does not tolerate the stress.
Its ability to cause melting and casting, the theme is good.
+++
I assume the question asks why cast-iron is the main material for making the lathe - and in fact most machine-tools.
'
It is easy to machine and gives very good bearing surfaces such as the shears on the lathe bed; thanks to its inherent "self-lubricating" and oil-retaining property due its granular structure of iron crystals interspersed with those of graphite - you soon find the graphite when you machine the stuff!
'
It has a damping effect - it is not as resonant as steel so reduces vibration.
'
Re-writing the first respondent's last sentence as I think he meant: it melts at a relatively low temperature, and its low viscosity when molten greatly facilitates casting intricate shapes.
What is the name of a person who operates a milling machine?
A person who operates a milling machine is called a milling machine operator, milling machinist or a machinist.
What is the difference between b tooling and d tooling?
B tooling is having head and body more than d tooling
As b has 1.5 & length of 5.13 body 1 inch
d has 1 inch head and length 5.13 body 0.73
Although a lathe can bore and drill, it is actually associated with turning.
A drilling machine is associated with drilling, a milling machine with milling, and a boring mill with boring.
What tools do you use to change an alternator on a 93 Saturn SL1?
You'll need some metric sockets. 3/8" drive will be fine. Maybe a small extension and the ratchet. Not to many tools involved.
What are the types of tool post?
the types of tool post on lathes can be classified as
single screw tool post
four bolt tool post
open side tool post
four way tool post
What is sales tax rate in Madison county Alabama?
It really depends on where in Madison County you are asking about. The county has a standard 1/2% rate, the state has a 4% rate, and each municipality has their own rate on top of that. So, for example, Huntsville's rate is 3.5% so the total tax in the city limits is 8% after you add the city tax rate, but rural areas are 5.5%. There is ongoing debate however on raising the county tax there 1/2% and the state is considering removing the 4% rate on food only.
Phenology can be a useful tool in environmental monitoring.here what is phenology in this context?
Phenology is the study of how climate affects the environment. For example, when the birds start to go south for the winter, the climate will change or has already changed to cooler temperatures.
What does CRC mean in relation to CNC programming?
CRC refers to "Cutter Radius Compensation". To ensure compliance to the drawing specification of a machined radius, the tip radius of a cutting tool has to be taken into account to compensate for the actual required value of a radius when it is programmed into the CNC.
Cricket originated in England during the 16th century, evolving from various bat-and-ball games played in the region. The first recorded mention of cricket dates back to 1597, and it was formalized with established rules in the 18th century. The sport gained popularity and spread to other countries, leading to the formation of international matches and governing bodies like the Marylebone Cricket Club (MCC). Today, cricket is played globally, with significant followings in countries like India, Australia, and England.
