CNC Instrument Lathe

 CNC instrument lathe is actually a branch of the CNC lathe. The biggest feature of the CNC instrument lathe is that the workpiece is mainly clamped with a spring chuck. This method is especially suitable for the clamping of batches of small workpieces. Only one push of the handle is needed to complete the clamping of the workpiece, and the clamping speed is less than one-third of the workpiece clamped by the manual chuck, the manual chuck clamps the workpiece and requires three movements, even much faster than hydraulic chuck clamping. A skilled worker can often operate 2-3 CNC instrument machines at the same time. Of course, CNC instrument lathes can also use manual chucks and hydraulic chucks to clamp workpieces, which should be optional accessories.

Introduction

CNC instrument lathe, also known as CNC (Computer Numerical Control) instrument lathe, is a computer numerically controlled lathe.

Ordinary horizontal lathes rely on the manual operation of machine tools to complete various cutting processes, while the CNC lathe machine input the prepared processing programs into the CNC system, and the CNC system completes operations through the lathe. The servo motors of the X and Z coordinate axes control the action sequence, movement amount, and feed speed of the moving parts of the lathe, coupled with the steering of the spindle speed, and the automatic tool change system, so that various shafts with different shapes can be processed, such as slass or disc-like parts of revolution. Therefore, CNC instrument lathes are the most widely used machine tools at present.

Instrument lathe is a general term, it is mainly processing some small but not very precise parts. The instrument lathe can be used to process the oil needles, screws of the motorcycle carburetor. The more rudimentary ordinary instrument lathe has only one motor and one-bed body, which is very simple.

Principle

The instrument lathe adopts a spring chuck for quick clamping, the motor directly drives the main shaft, the large and small discs are operated quickly by hand, and the turning is controlled by vertical and horizontal positioning. The instrument lathe can be used to process external circle, internal circle, cutting off, end face, cutting groove, turning taper, drilling, reaming, tapping, milling, grinding, and other functions. It is widely used in electrical appliances, fasteners, automobile, motorcycle accessories, instrumentation, hardware appliances, cultural and educational supplies, film and television equipment, mechanical and electrical products, plumbing fittings, valves, bearing rings, shafts and other small parts, glasses manufacturing and other small workpieces It is the most ideal high-efficiency equipment in the hardware machining industry.

Due to the use of hand-push tool feed, quick clamping of spring chuck, thimble-type limit device, and rapid hand-operated operation, the motor directly drives the spindle to run, and the positioning controls the turning. Continuous processing of a single fixed type of workpiece and appearance is comparable. Ordinary lathes improve work efficiency by more than 10 times and are especially suitable for the processing of large batches and small parts. The CNC instrument lathe can replace other machine tools to save energy consumption.

Operation method

1. In addition to using manual spring chucks to clamp workpieces, CNC instrument lathes can also use pneumatic spring chucks and hydraulic spring chucks to clamp workpieces.
2. For short bars, spring backers must be set in the collet, not only can it be directly clamped in place without re-setting the tool, but also the workpiece can be automatically ejected after processing.
3. For the mass production of long bars with a diameter of less than 20 mm, an automatic long material feeding system must be installed, which can greatly improve work efficiency. As for the method of pulling or pushing, it should be determined according to the workpiece.
4. For mass-produced workpieces that can use short material automatic feeding, try to install an automatic feeding system.
5. Those who can use the tool holder to clamp the tool should use the tool holder as much as possible. The tool holder can avoid the repeated positioning error and failure rate of the electric tool holder.
6. If you want to increase the number of clamping tools, you can use the coexistence of electric tool rests and row tool rests. Our term is called dual-use electric row.

The Basic Nine Operation Steps Of Common CNC Machine Tools

 CNC machine tools, I believe that everyone who has been in contact with the machinery industry knows that CNC machine tools can be more easily controlled by computers, which not only saves manpower but also greatly improves work efficiency. The following is the general operation process of CNC machine tools, let’s take a look!

1. Editing and input of workpiece programs

Before processing, the machining process and processing program of the workpiece should be analyzed and compiled first. If the processing program of the workpiece is long or complicated, do not program on the CNC lathe but use a programming machine or computer to program, and then back it up through a floppy disk or communication interface. into the CNC system of the CNC lathe machine. This can avoid occupying machine time and increase the auxiliary time of processing.

2. Boot

Generally, the main power is turned on first, so that the CNC machine tool has the starting conditions. Start a CNC system with a key button and the machine tool is powered on at the same time. The CRT of the CNC machine tool system displays information. Connection status of clam and other auxiliary equipment.

3. Fixed reference point

Before machining the machine tool, establish the movement datum of each coordinate of the machine tool.

4. Input call of the machining program

According to the program medium (tape, disk), it can be input by a tape machine, programming machine, or serial communication. If it is a simple program, it can be input directly on the CNC control panel by keyboard, or input segment by segment in MDI mode for remote segment processing. Before machining, the origin of the piece, tool parameters, offset, and various compensation values ​​must also be input into the Garding program.

5. Program editing

If the program under the jurisdiction needs to be modified, the working mode selection switch should be placed in the editing position. Use the edit key to add, delete, and change.

6. Program inspection and debugging

First, lock the machine and run the system only. This step is to check the program. If there is any error, it needs to be edited again.

7. Workpiece installation and alignment

Install and align the next part to be processed and establish a benchmark. The method adopts manual incremental movement, continuous movement, or manual wheel movement of the machine tool. Set the starting point to the beginning of the program, and set the reference of the tool.

8. Start the axes for continuous machining

Continuous processing generally uses program processing in memory. The feed rate in CNC machine tool processing can be adjusted by the feed rate switch. During processing, you can press the feed hold button to pause the feed movement to observe the processing situation or perform the manual measurements. Press the cycle start button again to resume processing. In order to ensure that the bowl is correct, it should be re-checked before processing. During milling, for plane curved workpieces, a pencil can be used instead of a tool to draw the outline of the workpiece on the paper, which is more intuitive. If the system has a tool path, the simulation function can be used to check the correctness of the program.

9. shutdown

After processing and before turning off the power, pay attention to checking the status of the CNC machine tool and the position of each part of the machine tool. Turn off the machine power first, then turn off the system power, and finally turn off the main power.

Advantages Of CNC Lathes

 dvantages Of CNC Lathes

Programmable logic controller (Programmable Logical Controller, PLC for short) is the important part of CNC lathes, it is also a general-purpose automatic control device based on the processor, which is used to complete various logic operations and sequence control of CNC machine tools, such as machine tool start and stop, workpiece Auxiliary actions such as clamping, tool change, coolant switch, etc. PLC also accepts the instructions of the machine tool operation panel. On the one hand, it directly controls the action of the machine tool; The PLC in the CNC lathe machine has a built-in type and independent type.

The operation of the numerical control machine tool is realized through the man-machine operation panel, which is composed of the numerical control panel and the machine tool panel.

The CNC panel is the operation panel of the CNC system, which consists of a display and a manual data input (Manual Data Input, MDI) keyboard, also known as the MD panel. The lower part of the display is often provided with a menu selection key for menu selection. In addition to various symbols, numbers and functions, the keyboard can also be set up! User-defined health is also can be checked automatically . The operator can realize system management through the keyboard and display, input, store, edit and modify the numerical control program and related data. During processing, the screen can dynamically display system status and fault diagnosis report. In addition, the numerical control program and data can also be imported through the disk or the communication interface box.

The machine tool operation panel is mainly used for the operation of the machine tool in the manual mode, and the operation or preview of the machine tool in the automatic mode. There are various buttons and selection switches on it, which are used for starting and stopping of machine tools and auxiliary equipment, selection of processing methods, selection of speed magnification, etc. There are also digital tubes and signal displays. The operation panel of medium and small CNC machine tools is often integrated with the CNC panel, but there is a clear boundary between the two. The communication interface of the numerical control system, such as the serial interface, is permanent and on the machine tool operation panel.

Development trend

Since entering the 21st century, with the continuous development of CNC technology and the expansion of application fields, it has played an increasingly important role in the development of some important industries (IT, automobile, light industry, medical care, etc.) for the national economy and people’s livelihood. The digitization of required equipment is a major trend in modern development. In general, CNC lathes show the following three development trends.

High speed and high precision

High speed and precision are the eternal goals of machine tool development. With the rapid development of science and technology, the speed of replacement of electromechanical products is accelerated, and the requirements for the precision and surface quality of parts processing are also higher and higher. In order to meet the needs of this complex and changeable market, the current machine tools are developing in the direction of high-speed cutting, dry cutting, and quasi-dry cutting, and the machining accuracy is constantly improving. On the other hand, the successful application of electric spindles and linear motors, ceramic ball bearings, high-precision large-lead hollow internal cooling and ball nut strong cooling low-temperature high-speed ball screw pairs and linear guide pairs with ball cages and other machine tool functional components The launch of the machine tool has also created conditions for the development of high-speed and precision machine tools.

The CNC lathe adopts an electric spindle, which cancels the links such as belts, pulleys, and gears greatly reduce the rotational inertia of the main drive, improves the dynamic response speed and working accuracy of the spindle, and completely solves the problem of belts and pulleys when the spindle runs at high speed. Vibration and noise issues. The use of an electric spindle structure can make the spindle speed reach more than 10000r/min.

The linear motor has high drive speed, good acceleration, and deceleration characteristics, and has excellent response characteristics and following accuracy. The use of linear motor as servo drive eliminates the intermediate transmission link of the ball screw, eliminates the transmission gap (including backlash), the motion inertia is small, the system rigidity is good, and it can be precisely positioned at high speed, thus greatly improving the Servo accuracy.

Because of its zero clearance in all directions and very small rolling friction, the linear rolling guide pair has small wear and negligible heat generation and has very good thermal stability, which improves the positioning accuracy and repeatability of the whole process. Through the application of linear motor and linear rolling guide pair, the rapid moving speed of the machine tool can be increased from 10-20m/min to 60-80m/min, and the highest is 120m/min.

High reliability

The reliability of CNC machine tools is a key indicator of the quality of CNC machine tools. Whether the CNC machine tool can exert its high performance, high precision, and high efficiency, and obtain good benefits, the key depends on its reliability.

CNC lathe design, Structural design and Optimization

With the popularization of computer applications and the development of software technology, CAD technology has been widely developed. CAD can not only replace the tedious drawing work with manual work, but more importantly, it can carry out design scheme selection and static and dynamic characteristic analysis, calculation, prediction, and optimization design of the large-scale whole machine, and can carry out dynamic simulation of each working part of the whole machine. . On the basis of modularity, the three-dimensional geometric model and realistic color of the product can be seen in the design stage. The use of CAD can also greatly improve work efficiency and improve the one-time success rate of design, thereby shortening the trial production cycle, reducing design costs, and improving market competitiveness.

Chucker CNC Lathe Maintenance And Programming

 Chucker CNC Lathe is an automatic machine tool with high precision and high efficiency. Equipped with a multi-station turret or power turret, the machine tool has a wide range of processing performance. CNC turning machines can process linear cylinders, oblique cylinders, circular arcs, various threads, grooves, worms, and other complex workpieces. CNC lathe machine has various compensation functions of linear interpolation and circular arc interpolation and has played a good economic effect in the mass production of complex parts. The maintenance of the NC lathe with the inclined bed is analyzed as follows:

In order to ensure the working accuracy and prolong the service life of the inclined bed NC lathe, it is necessary to carry out reasonable maintenance for the self-use inclined bed NC lathe. The quality of lathe maintenance directly affects the machining quality and production efficiency of workpieces. When the Taiwan Taiyu precision Chucker CNC lathe runs for 500h, it needs first-class maintenance. The maintenance of the inclined bed Chucker CNC lathe is mainly carried out by operators and coordinated by maintenance workers. During maintenance, the electric probe must be cut off first, and then the maintenance shall be carried out according to the maintenance contents and requirements.

NC Programming

Chucker CNC lathe preparation function g code (jb3208-83). G code (or G instruction) is a process instruction that needs to be specified in advance before interpolation operation of NC machine tool system to prepare for interpolation operation, such as selection of coordinate plane, designation of interpolation mode, designation of fixed cycle functions such as hole machining, etc. G code is composed of address g followed by two digits. G00 ~ G99 are commonly used. Some modern CNC machine tool systems have been extended to three digits. G codes are divided into modal codes and nonmodal codes according to functional categories. a. C, D,… J, K, and other 9 groups. The G code corresponding to the same group is called modal code, which means that once a G code in the group (such as G17 in group C) is specified, the function will remain valid until any other code in the same group (such as G18 or G19) appears, otherwise it will remain valid. Therefore, when compiling the next program segment, if the same G code needs to be used, it can be omitted, which can simplify the processing programming. The nonmodal code is only valid in this section.

Note: 1. G codes indicated by lowercase letters a, B, C, D,… Are the same group of codes, which are called modal instructions;

2. “#” represents that if it is selected for a special purpose, mini CNC lathe must be described in the program format description;
3. The letter (d) in the brackets in the second column can be canceled or replaced by the letter (d) without brackets in the same column, or by the letter (d) with brackets;
4. “Do not specify” and “never specify” codes respectively indicate that new functions and never specify functions can be specified when the standard is revised in the future;

When the CNC system does not have g53 to G59 and g63 functions, it can be designated for other purposes.
