What is Inverter Transmission Lathe

Inverter Transmission Lathe

A lathe is a machining tool that is utilized primarily for shaping materials. It works by rotating the workpiece around a stationary cutting tool. The main purpose is to remove unwanted parts of the material, leaving behind a nicely shaped workpiece.

Introduction to Inverter Transmission Lathe

Inverter transmission lathe is a specific type of lathe that is equipped with an inverter motor to transmit the moving energy, which then translates to the operating speed of the lathe. Basically, there are three types of inverter transmission lathes. An inverter transmission lathe possesses features including a rotary switch to control the spindle speed and the motor to save power and energy more efficiently.

What Is a Lathe?

A lathe is a machining tool that is utilized primarily for shaping materials. It works by rotating the workpiece around a stationary cutting tool. The main purpose is to remove unwanted parts of the material, leaving behind a nicely shaped workpiece. A lathe is employed to carry out a variety of machining processes including cutting, sanding, knurling, drilling, and turning. It also executes these processes utilizing the same technique — with a workpiece rotating against a stationary cutting tool.
Lathes live up to their names; they focus on the ability to turn materials on the lathe machine. Lathes are frequently utilized to deform and reshape wooden workpieces. Wood, of course, is considerably softer than most metallic materials. When deforming or reshaping a metal workpiece is necessary, the assistance of a lathe is probably required. It’s quite essential to recognize that lathe can still be utilized on wooden workpieces. Wood lathes only support wooden workpieces, but metal lathes support both metal and wooden workpieces.

Construction of a Lathe

A lathe has two ends: a headstock that spins and a tailstock that stays still to hold a workpiece. There are two standard measurements in lathes to look at: one is the distance between the centers of the headstock and the tailstock, and the other is the center height. Both measurements are critical factors when buying a lathe. Swing measurement designates the distance between the pivot of the headstock and the bed. Some mini lathes only have 3 speeds or pulse width modulated DC motors whereas some might have a gearbox that has up to 6 speeds ranging from 100 to more than 1500 rpm to rotate the spindle.

Small-scale Use of a Lathe

Most lathes tend to be compact whereas some can be quite large. Many machinists, hobbyists, and craftsmen find lathes to be indispensable. You can utilize a lathe to create parts for an old car or a simple bowl. A skilled craftsman can turn a lump of metal into a cup, a lampstand, or even a chess-piece. A lathe has a wide variety of applications, and the ability to freehand the cutting and carving stages means that each piece still possesses the unique touch of the craftsman. A lathe is not limited to particular alloys or metals: some metals may be easier to work with, but in theory, any metal can be turned into a lathe.

Main Components of Lathe


Like most power tools, a metal turning lathe contains a motor. The motor serves as the power source of the lathe. There is often a speed control dial on the motor to control the power output. Metal lathes that go in both a reverse and forward direction will have a switch, so you can alter these movements accordingly. The power of a motor is measured in HP and ranges from 1/8 HP to 3HP. The speed of the motor varies based on the model.

Chuck and Spindle

A spindle is a hollow device that rotates the material clamped on it. The rotation is driven by the motor. Rotating the material allows you to employ the tool to shape the material. A chuck is an attachment that clamps the material onto the spindle. Chuck is a work-holding system that holds the material. Chucks can be grouped into the 3-jaw chucks (i.e., universal chuck) and the 4-jaw chucks (i.e., independent chucks). There are also specialized chucks that are able to fit stocks in special shapes, and some of them are included as accessories bundled with the lathe.


Tool-rests are exactly what the name implies – a device for the cutting tool to rest onto. As using a metal lathe can be hazardous at the best of times, this is a very essential respect to have on your lathe. Tool-rests are adjustable, so you’re capable of moving this into the position that’s best suitable for the metal you’re working on. Some tool rests can hold up multiple tools, making interchanging between tool bits convenient.

Cross Slide and Carriage

The carriage is carried by the carriage handwheel, which is positioned on the front of the lathe. This moves the carriage both towards and away from the headstock – The direction is controlled by the operator with the handwheel. The cross slide enables you to move your tools into your pieces and has a dial on the handle. This handle is extraordinarily useful, as it pinpoints the location of the cross slide, with a very tiny error rate.

Bed, Tailstock, and Headstock

The bed on a lathe refers to the horizontal beam that runs across the foundation of your metal lathe. Generally speaking, beds are made from cast iron to keep the entire lathe weighted. This exterminates inaccuracies, as the heavyweight of the cast iron construction minimized vibrations. One typical term you’ll see all the time with metal lathes is the bed swing. Bed swing is the width of the material that the lathe can work with. The other 2 important features of a metal lathe are the head and tailstock. The headstock is fixed on the front end of a lathe. rotates the stock. The tailstock can be shifted in order to fit the size of the stock.

Lathe Safety

Safety is always an issue whenever operating a cutting tool, and it is important to always familiarize yourself with the machine to the largest extent. As you might know from experience, there are some moments when mistakes take place. You should be wearing safety goggles with side protectors if you're in a machine shop. If the gloves, a watch, or a small piece of personal accessories got caught in a spindle or the cutting bit, you may find yourself in a dire situation. To avoid any unnecessary injury, safety wears are a must when exploring an environment where cutting tools are involved.
