CNC Milling Machine 3 Axis VMC1260

3-axis CNC machining evolved from rotary filing. With a 3-axis CNC machine, the workpiece is stationary while the cutting tool moves across the X-, Y-, and Z-axes. The X-axis (vertical axis) is left to right along the lathe table, the Y-axis (horizontal axis) is from front to back of the table, and the spindle that drops from the top marks the Z-axis (depth). A standard 3-axis CNC milling machine has a table that moves the part to provide one or two planes of movement and a tool that provides the other one or two planes of movement. 3-axis machines are ideal for simple tasks that don't require intricate detailing or depth. As such, it is one of the most preferred techniques for creating mechanical parts for automation.

What is Machining Center With High Precision1580

Advantages of Machining Center With High Precision1580

Low Error
By using CNC machines, once the correct specifications are keyed in, the automated precision machining process takes over. The chances for error is extremely low as compared to human machining. When you outsource this work, you avoid the need to recruit and hire the highly skilled staff needed to run these machines.

Less Material Waste
As the core concept of precision machining is subtraction, there is enormous potential for material waste from start to finish on a single product. CNC precision machining helps reduce material costs due to wastage from human error. Contract companies may also be buying the material needed for your job is bulk, and pass the savings on to you.

Consistent Product Quality
Precision machining via CNC machines leads to consistent output time after time. Consistently producing quality product runs leads to customer confidence and enhances your brand's awareness.

Improved Workflow
When looking at how to manage opportunity costs, it's key that engineers' time and skills are spent in actual product development and not tiny design changes. A company that offers contract precision machining services can usually assist with minor modifications during the prototyping process to meet design and/or industry standards.

Reduced Turnaround Time
Opportunity exists to improve your existing factory workflow (either with in-house precision machines if you can afford the machine investment and the skilled labor to operate it), or, by using contract machining services. A contract company is experienced in this type of work and have the system in place to get the job done as efficiently as possible.

Faster Production Cycles
Being able to offer your product to market faster gives you an edge over facilities that are still using older methodologies. You're also likely to be more flexible with changes due to industry regulations or customer requests.

Easier Prototype Testing
Precision machining offers your business an opportunity to explore smaller niche markets with potential for high returns. Precision CNC machining can allow for a flexible product-development phase as the niche opportunity is determined. If the market has a demand, the machining can be shifted into a full-scale production mode. Precision machining also allows for prototypes to have functional parts, as opposed to a more concept/design prototype. Functional prototypes instill more confidence from investor stakeholders than concept-only.

Steps in the precision machining process

Design the Graphical Model

A graphical model is required to create any part. This is accomplished with the help of Computer-Aided Design (CAD) software. The CAD software enables the designer to create 2D and 3D models of any part for manufacturing. It is common for designs to start as hand-drawn sketches to understand the basic concepts of the part. The Computer-Aided Design (CAD) designer then refers to these sketches to create the graphical model with accuracy in dimensions. For Computer-Aided Design, there are many popular software programs, both free and paid. Manufacturers can also outsource the design process for any complex design development.

Convert CAD to CAM

Computer-Aided Design creates a graphical representation of the part in a digital format. This representation is easy for the designers, operators, and manufacturers to understand. However, CNC machines used to create the part do not understand this digital format directly. The machine understands coordinates where it can move the cutting tool or shift the workpiece. Therefore, CNC machines require the part design to be in a suitable format that provides the necessary manufacturing instructions. Computer Aided Manufacturing (CAM) software is used to create the readable format for CNC machining. The CAM software takes the CAD model and converts it into CAM format that the CNC machines can understand. Computer Aided Manufacturing (CAM) software uses two types of codes – the G and M codes. The G code controls the coordinates of the cutting tool. The M code controls the auxiliary functions of the machine, such as turning the coolant flow on or off.

Machine Setup

Once the designs are ready in CAM format, it is time to do the machine setup. This will typically require machine tool calibration and mounting of the workpiece on the machine. The machine tools can vary based on the workpiece material and design of the final part. There are various precision machining tools available for different purposes. In this step, it is important to tighten all the clamps correctly and ensure the machine parameters, such as the coolant levels, are acceptable.

Execute the Machining

Once the setup is complete, the machine program is ready to execute. Most CNC machines have a display to monitor the program and adjust various parameters. When the program is executed, the CNC machine will begin the precision machining process.

Completion

Once the part is manufactured using the precision machine, it can be removed. Depending on the requirements, the part may be sent for secondary processes such as grinding or polishing. However, in most cases, a finished product created using precision machining does not need any secondary processing.

5 Factors Affecting CNC Machining Accuracy

The machine tool is heated up
In the process of operation, the CNC machine tool itself will generate a certain amount of heat, such as motor operation, component friction and other factors, which will cause the temperature of the machine tool to continue to rise, resulting in adverse effects on components and structural systems due to thermal effects, such as tool shift in the machine tool. , CNC machining parts wear, thermal expansion of components, line burning and other phenomena, resulting in reduced CNC machining accuracy of parts. In addition, the installation of machine tools is mostly in unventilated places, and external environmental conditions such as limited heat dissipation conditions will also cause the temperature to rise. This will increase the burden of machine tool operation, reduce the accuracy of CNC machining parts, and in severe cases may cause mechanical failures, which directly affect the efficiency and quality of CNC machining.

The error and wear of the tool itself
The tool in the machine tool is also one of the CNC machining parts. In its own production and machining process, there are geometric errors that affect the accuracy due to the limitation of CNC machining conditions. In the process of tool installation, human operation will also affect the machining accuracy. In the process of use, due to the long-term contact between the tool and the CNC machined parts, the deformation caused by friction and high temperature and other factors will also cause the tool to wear to varying degrees. Of course, when the wear accumulates to a certain extent, it will also have a significant impact on the CNC machining accuracy.

CNC machining position error
CNC machining parts all have basic error requirements such as surface, shape, radian, relative relationship, etc. CNC machining must complete the design requirements of the parts and meet the machining performance and quality requirements. In the process of CNC machining, due to the influence of various factors such as transmission parts, rotating shafts, and frictional forces of parts, the accuracy of the appearance, size, and relative relationship of CNC machined parts is deviated, which reduces the accuracy of parts machining. For example, in the process of CNC machining, the swing angle of the CNC machining axis will be wrong, which will cause the shape of the CNC machined parts to be deformed, the accuracy will be reduced, and even cause the CNC machined parts to be scrapped in batches, which will bring great economic losses to the enterprise.

Error of CNC machining system
The machine tool machining system of CNC machine tools is the part that directly implements parts machining. It is a whole that is composed of multiple subsystems and sub-components in a certain way and operates together. The operation of each component will affect the CNC machining of the entire machining system. Accuracy has an impact. Therefore, the system error is constantly generated by multiple components in the process of installation and operation, and the error of the machining system can only be minimized by means of technological progress and improvement of construction progress.

Deformation error
During the long-term use of CNC machining, CNC machine tools will be affected by external forces, such as clamping force, gravity, friction, etc., which will cause deformation, loosening, elastic deformation, displacement and other deformation phenomena of the CNC machining system of the machine tool, resulting in machine tool failure. Production accuracy and production efficiency decline. Under the influence of external force, the machine tool will not only reduce the precision of production CNC machining but also cause damage to the machine tool in severe cases, affecting the service life. Therefore, it is necessary to pay attention to the research on the influence factors of external force on CNC machine tools to reduce the influence on the machine tools.
