On the question of CNC machine tools, what is a CNC machine tool

If it is the same type of mass production, it is best to make a fixture, after the fixture is fixed, the first knife, the subsequent workpiece is guaranteed by the fixture, so as to avoid clamping errors.

If it is a single piece and a small batch, there are two types. 1. X, Y direction with eccentric tool setter, the upper and lower parts are eccentric, the spindle rotates, close to the workpiece, when the upper and lower parts are coaxial, you can, and then subtract the radius of the instrument. Rotate the upper surface with a knife and gently scrape it on, and you're good to go.

2. Buy a standard measuring rod of standard size, that is, a round bar and the tool handle are integrated, if there is no suitable size to find the tool manufacturer to order, cylindricity, symmetry, radial tolerance, surface hardness to meet the requirements on the line. Mounted on the spindle without rotating, close to the workpiece, use a gauge block to plug, and then subtract the radius of the standard rod and the thickness of the gauge block from the nearest position that can be stuffed. This method is fast and accurate, within the limit.

The same goes for the upper surface.

If the machine tool supports optical sensors, you can buy a laser tool setter, and then compile the tool setting macro program, which is also very convenient.

Our company bought a VF-5TR machine tool from Haas Automation. Our company has chosen a tool setter. The abbreviated name in English is vqcps

It can utilize the Haas Visual Fast** Probe System including Tool Setup Probe, Working Bias Probe, OMI, ProMac, Coord, SO, VQC Templates and all software.

I recommend this machine tool probe system (tool setter) to the landlord. It uses the infrared remote sensing control system, which can directly input the probe coordinates into the system and convert the workpiece coordinate system without manual input of infrared communication.

For the landlord said that the right question. In the case of cylindrical bars, it is best to use a three-jaw or four-jaw centering chuck. The VQCPS probe can be used to correct the tool setting error.

That is to say, when the landlord uses VQCPS to align, as long as the cylindrical bar is measured in the positive and negative X and Y directions respectively (as long as the line of the positive and negative coordinates is about through the center of the material), the system can use infrared remote sensing to automatically correct the error, so as to achieve the purpose of the landlord's center, which is simple and practical. This is the most favorite and must-have operation tool in the machine for Americans.

The function of the tool setter is mainly to determine the size of the diameter and length direction of the tool, and its use method is to install the machining center tool holder on the tool setter, and the size of the diameter and length direction of the tool can be read, which has nothing to do with the machining shape of the part and the coordinate selection when programming. Generally, the dimensional accuracy of the diameter direction of a good tool setting instrument (referring to the import) can be controlled, that is, after the tool is aligned, it can be directly processed according to the size of the tool setting. The size of the tool is generally not taken into account when programming, as long as the compensation of the length direction or diameter of each tool is entered into the machine.

Therefore, it is recommended that you buy a good tool setter (referring to import).

A CNC machine tool is an automated machine tool equipped with a program control system.

The working principle of the CNC machine tool is to process the various operations required in the machining process (such as spindle speed change, workpiece release and clamping, entry and retract, start-up and stop, automatic shutdown of coolant) and steps and the shape and size of the workpiece are represented by digital **, through the control medium (such as perforated paper tape or disk, etc.) to send the digital information to the numerical control device, the numerical control device processes and calculates the input information, sends out various control signals, and controls the servo system or other driving elements of the machine tool. The machine tool automatically processes the required workpiece.

Features:

1. Strong adaptability to the processing object, adapting to the characteristics of single piece production of molds and other products, and providing suitable processing methods for the manufacture of molds.

2. High processing accuracy and stable processing quality.

3. It can carry out multi-coordinate linkage and process parts with complex shapes.

4. When the processed parts are changed, generally only need to change the CNC program, which can save production preparation time.

5. The machine tool itself has high precision and rigidity, and can choose a favorable processing amount and high productivity (generally 3 5 times that of ordinary machine tools).

6. The machine tool has a high degree of automation, which can reduce labor intensity.

7. It is conducive to the modernization of production management. CNC machine tools use digital information and standard processing and transmission of information, and use computer control methods, which lays the foundation for the integration of computer-aided design, manufacturing and management.

8. The quality requirements for operators are higher, and the technical requirements for maintenance personnel are higher.

9. High reliability.

What are the components of CNC machine tools.

CNC machine tools are generally composed of the following parts:

Host. He is the subject of CNC machine tools, including mechanical components such as machine bodies, columns, spindles, feed mechanisms, etc. He is a mechanical component used to complete various cutting operations.

Numerical control device. It is the core of CNC machine tools, including hardware (printed circuit boards, CRT displays, key boxes, paper tape readers, etc.) and corresponding software, which are used to input digital parts programs, and complete the storage of input information, data transformation, interpolation operations and realize various control functions.

Drives. He 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 high containing socks assist device.

Some necessary supporting components 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.

It 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.

CNC machine tool refers to a machine tool that can be programmed by computer and automatically controlled.

After the program instructions are input into the memory of the numerical control system, the computer compiles and calculates, and the information is transmitted to the drive to drive the motor through the displacement control system to cut the designed parts. The computer and the CNC machine tool are connected by parallel signal lines, and then the software of the CNC machine tool is used to control the processing. The CNC machine tool software is used to generate the G-code (function command), send the path code to the CNC machine controller, and then the CNC machine tool controller sends a command to drive the spindle motor and the slide table (XYZ axis) motor to start machining.

CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system is able to logically process and decode the programs specified by the control code or other symbolic instructions, so that the machine tool can operate the CNC press brake and process the parts.
