What issues should be noted when choosing a milling machine?

When choosing a milling machine, multiple factors need to be considered to ensure that high-quality equipment that meets processing needs and budget is selected. Here are some key precautions:

1、 Processing requirements

Workpiece type and size:

Select the appropriate milling machine type based on the size and shape of the workpiece being processed. For example, for the processing of small and medium-sized workpieces, smaller sized lifting table milling machines can be selected, while for the processing of large-sized and complex parts, larger gantry milling machines are required.

Consider the machining characteristics of the workpiece, such as whether it is necessary to machine spiral grooves, blade parts, etc., in order to select a suitable milling machine system (such as point line system).

Processing accuracy requirements:

Choose a milling machine based on the precision requirements of the workpiece being processed. The precision standards for different milling machines vary, and for workpieces with high precision requirements, precision CNC milling machines should be selected.

Understand the working accuracy indicators of milling machines, such as positioning accuracy, repeat positioning accuracy, machining accuracy, and surface roughness.

2、 Milling machine performance

Cutting ability:

The cutting ability of a milling machine is closely related to its spindle power, cutting speed, feed rate, and other parameters. Select a milling machine with sufficient cutting capability based on the hardness and processing speed requirements of the material being processed.

Consider the machining range of the milling machine, including the types of materials that can be machined and the size range.

Stability:

A stable structure can reduce the impact of mechanical vibration on machining accuracy. When making a purchase, one should observe whether the structure of the milling machine is stable and understand its stability performance in actual use.

3、 Operation and maintenance

Convenience of operation:

Choosing a milling machine that is easy to operate can improve work efficiency. Consider factors such as the control method and processing preset of the milling machine, and choose equipment that is easy to operate and maintain.

after-sale service:

Good after-sales service can ensure timely resolution of equipment problems. When making a purchase, it is important to understand the supplier’s after-sales service quality and policies, and choose a brand with good after-sales service.

4、 Other factors

Machine tool model and structure:

Determine the type of mold structure (such as long guide or short guide), whether it is an imported Murata structure or a high-speed structure, etc., in order to select the appropriate machine tool model.

Pay attention to the tonnage of the machine tool to ensure that the punching force of the mold is suitable.

Distance between rotating station and turntable:

If the machine tool workstation is a non rotating workstation, the double keyway structure of the guide sleeve or lower mold should be considered.

The distance between the upper and lower turntables of the machine tool should meet the height requirements of the lower mold.

Processing board information:

Determine the material and thickness of the processed sheet metal to select the appropriate mold material and gap.

Mold positioning direction:

Determine the direction of the positioning pin (groove) of the mold (especially the irregular mold) according to the processing requirements.

Mold type:

Clarify the type of mold ordered by the customer to ensure that the machine tool can meet the processing requirements.

Price and Budget:

The prices of milling machines of different brands and models vary greatly. When making a purchase, one should choose the appropriate equipment based on the budget, while being careful not to overlook other key factors due to price.

In summary, choosing a milling machine is a process that considers multiple factors comprehensively. By carefully analyzing processing requirements, milling machine performance, operation and maintenance, and other related factors, high-quality equipment that meets processing needs and has high cost-effectiveness can be selected.
