How does a lathe work, what is the working principle of a normal lathe?

I don't know if you're talking about CNC machines? In fact, CNC machine tools and ordinary machine tools are completely different, ordinary machine tools have a very complex transmission system and variable speed mechanism Most of them have only one drive motor and the mechanical structure of CNC machine tools is much simpler, there is no complex variable speed mechanism, because its motor is infinitely variable CNC machine tools are generally composed of the following parts:

The main machine, which is the subject of CNC machine tools, includes mechanical components such as machine body, column, spindle, feed mechanism, etc. He is a mechanical component used to complete various cutting operations.

The numerical control device is the core of the CNC machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and the corresponding software, which is used to input the digital part program, and complete the storage of input information, the transformation of data, the interpolation operation and the realization of various control functions.

The drive device is the driving component of the actuator of the CNC machine tool, including the spindle drive unit, the feed unit, the spindle motor and the feed motor. He implements the spindle and feed drive by means of an electrical or electro-hydraulic servo system under the control of a numerical control unit. When several feeds are linked, positioning, straight lines, plane curves and spatial curves can be processed.

Auxiliary devices, some necessary supporting parts of the index control machine tool, are used to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC indexing heads, as well as tools and monitoring and testing devices.

Programming and other ancillary equipment can be used to program and store parts outside the machine.

Since 1952, the Massachusetts Institute of Technology developed the world's first CNC machine tool, CNC machine tools have been widely used in the manufacturing industry, especially in the automotive, aerospace, and military industries.

Machining Center A machining center is a highly automated, multi-functional CNC machine tool with a tool magazine and an automatic tool changer. After the workpiece is clamped once on the machining center, it can complete a variety of processes on more than two surfaces, and has a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.

The machining center is divided into two categories: boring, milling and turning according to its processing process, and can be divided into three-axis, four-axis and five-axis machining centers according to the number of control axes.

The salary of CNC machining is indeed relatively high, generally more than 4000, and you can get thousands if you are good, but the premise is that you are very skilled. Another thing I have to say is: don't look at its high salary, it's actually very hard, and the working hours and work pressure are very high.

Overtime is a regular occurrence. High salaries are paid in exchange for sweat.

Structural principle of vertical CNC lathe.

The structure of ordinary lathes includes head box, tool box, pallet box (slide box), bed foot, bed, bed leg, smooth bar, lead screw, switch bar, motor, and electrical.

The working principle of the ordinary lathe is that the motor transmits the power to the head box, and the speed is changed through the head box, and the spindle drives the workpiece to do rotary motion, providing the main motion for cutting, and the large supporting plate, the middle supporting plate, and the small supporting plate on the supporting block template box are used for linear motion, which provides the right Zheng Nian to the movement for cutting.

What can be processed by the general bed, CNC may not be able to process.

What can be processed by CNC must also be processed by ordinary beds.

But in front of the masters, the gap is very small.

What is the difference between the incomes and the two?

It depends on the attitude of the head of the unit and the calculation method.

It depends on the product shape and batch size of the unit.

It depends on the skill level and mobility of the employees themselves.

1.The main structure of the lathe: the ordinary lathe is mainly composed of the bed, the spindle box, the feed box, the slide box, the tool holder, the smooth bar, the lead screw and the tailstock and other components.

2.Principle. The main motor M1 completes the drive of the main movement of the spindle and the longitudinal and transverse feed movement of the tool, and the motor is a cage-type asynchronous motor with unregulated speed, adopts direct starting mode, the spindle adopts mechanical speed change, and the forward and reverse rotation adopts mechanical commutation mechanism.

The cooling pump motor M2 provides coolant during machining to prevent the temperature rise of the tool and workpiece from being too high. It adopts direct starting mode and continuous working state.

The motor M3 is a fast-moving motor for the tool holder, which can be manually controlled to start and stop at any time according to the needs of use.

3. The electrical schematic diagram, wiring diagram, and component layout diagram are the basis of the three. First, students will read the electrical schematic diagram and the use of component indexing methods, and then master the starting and braking methods of three-phase asynchronous motors on the basis of mastering basic concepts and skills such as self-locking and interlocking.
