Woodturning
Woodturning is the turning of wood by some sort of power on many types of lathes to shape it into a desired form, in woodturning the wood moving, between centers or mounted to a face plate and the tool is stationary. All questions about equipment, tools, techniques and materials can be found here.

Difference between lath martensite and plate martensite?
Lath martensite and plate martensite are two morphologies of martensite formed during the rapid cooling of austenitic steel. Lath martensite appears as thin, elongated plates or laths and is typically found in low-carbon steels, resulting in a more ductile microstructure. In contrast, plate martensite consists of thicker, broader plates and is generally found in high-carbon steels, leading to higher hardness and brittleness. The differences in their formation and structure influence the mechanical properties of the steel they comprise.
What is a Swiss lathe machine used for?
Swiss-style lathes are used for machining components requiring extreme accuracy. some of these lathes are capable of machining to within 0.00025mm or 0.00001in. Swiss-style lathes are used for smaller and/or longer workpieces, the lathes are applicable for different industries to machine parts.
How do you turn a bar on a center lathe?
The basics procedure used for turning a bushing on lathe are:
- Material is inserted and tightened into the chuck so it protrudes about 10mm over the actual length of the final bushing length
- If the material is not hollow bar, a drill is inserted into the tail stock then the material is drilled to enable the a boring bar to fit the hole
- A roughing tool is inserted into the tool post then the face of the workpiece is machined smooth and the outside diameter to about 0.5mm oversize
- A roughing boring bar is inserted into the tool post and the inside diameter is machined to roughly 0.5mm undersize
- A finishing tool is then inserted into the tool post then first the face and then the outside diameter of the workpiece is machined to the required size
- At this point a finishing boring bar is inserted into the tool post and the inside diameter is machined to the required size
- Chamfer tools are then used to chamfer both outside and inside edges at the face
- The parting tool is inserted into the tool post then the bushing is parted off about 0.5mm to 1mm longer than specified.
- The remainder of the material is removed from the chuck then the parted bushing is inserted and tightened with the unfinished side protruding about 5mm to 10 mm.
- A finishing tool is inserted into the tool post then the face is machined to the required size
- Chamfer tools are then used to chamfer both outside and inside edges at the face
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!
It is important that you should read see the answer to the Related Question shown below: "Would 120 volts appliances work on 230 volts in Europe?"
<><><>
This question is asking just about the motor. No electronic controls are associated with it.
<><><>
The speed will be different. The motor may heat up more lowering it's total life expectancy. Best you contact a licensed electrician that knows of European devices.
<><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

Why is NC lathe frame structure slanting 60 degrees?
The bed of a NC lathe is at an angle just to ensure swarf slides to the bottom of the machine for collection. They are referred to as "slant-bed lathes". The angle of the bed is dependent to the manufacturer. Some built 90 degree or vertical beds (Monarch Machine Tool Series 220 for example), and others built lathes at varying angles from horizontal, 70, 60 and 45 degrees are the most common, with 45 degrees about the shallowest angle that can be had and still have good chip flow. Other builders use a horizontal base, and use a triangular carriage to achieve the slant effect to shed chips and coolant.

What is a lathe indexing plate?
Simple indexing consists of a series of preset holes in a backing plate, these divisions are provided for the most common angles (such as 90 °, 45 °, 30 °, etc). The remaining divisions of a circle are provided by manually rotating the dividing arm using index plates. Tables or calculations are required to use this method. Indexing plates

How could you clean up a piece of wood that is very rough?
If the rough wood is in its natural state with no staining or varnish, buy sandpaper in various sizes for the grain. You will need large grain, which takes off the worst areas. But large grain can gouge wood that is already mostly smooth (be careful - when you purchase the sandpaper, bring the piece of wood or a picture with you and ask the hardware store's staff). You will then use a medium grain sandpaper to smooth out any remaining rough areas. You should be able to wipe your hand across the wood without feeling jagged spots. Lastly, the fine sandpaper will further smooth the wood and bring out more of the wood's character.
If the wood is stained or stained and varnished, your task will be more complicated. You would need to sand off all layers of varnish and stain, including at corners and joints, removing any hardware. If there are curves or decorative flourishes, it becomes very detailed work. Depending on the size of the object, and how complicated it is, the project could take you many months to complete.
Remember that sanded wood will need stained with 1 to 3 coats (wood soaks up stain), then varnished with 1 to 3 coats. Pick your stain wisely; it is better to start with a lighter stain (the color of Pine), than to go dark immediately (the color of oak or mahogany). Each coat needs 12-24 hours or longer of drying time. If you live in a humid area, the products might remain tacky for many days. Always check with professional before investing in a project. It might be cheaper to hire a woodworker or carpenter to make your project beautiful the first time.
If facing a flange pipe on a lathe what is the circumference?
Circumference is the distance around a circle (closed curve) which in this case would be the flange's circumference. A circumference is calculated by using the mathematical constant of Pi (3.143). It entails multiplying the outside diameter by 3.143.
Example: Diameter = 145mm
145 multiplied by 3.143 equals 455.735mm

A CNC lathe and milling machine tool holder is a mechatronic device. Why?
Cause CNC tool holder is mechanical system, driven by electric motor(electronics), which is controlled by computer (software). So here you got mechanical engineering, electronic engineering and computer engineering.-also, when the machine is running your program, a tool change call enacts a bulletproof series of events. When a toolchange is executed, the process is usually very swift and precise. It must be mechatronic for that reason as well.
What is the difference between wood lathe machine and wood lathe duplicator?
A lathe has one workpiece spinning on an axis, which the operator holds a tool to to cut the material. A duplicator has two workpieces, and a probe touching one piece causes a tool to cut in to the other, creating a duplicate of the probed piece.
