Mini 5 axis milling machine

Types of mini 5 axis milling machines

Mini 5 axis milling machines are generally divided into two types based on their movement modes: simultaneous 5-axis milling machines and 5-axis positional milling machines.

• Simultaneous 5-axis mini CNC machines: These machines have the ability to move the workpiece and tool at the same time in 5 axes. This means that the workpiece can be positioned in any orientation, which allows for more complex shapes and designs to be milled. Simultaneous 5-axis machines often have 5 simultaneous axes, which can rotate around X, Y, and Z axes, plus two additional axes (usually A and B axes). This extra range of motion allows the machine to approach the workpiece from multiple angles without having to reposition it. Simultaneous 5-axis milling machines are usually more complex than 3+2-axis machines and are able to perform more complex machining, but they are also more expensive, making them more suitable for advanced applications.
• 5-axis positional mini milling machines: 5-axis positional milling machines can adjust the angle of the spindle head and rotary table in two directions. It can be used to cut the workpiece from five different angles without repositioning the workpiece. Although their work efficiency is lower than that of 5-axis simultaneous milling machines, they are more cost-effective and are suitable for some small businesses that do not require high precision. In addition, 5-axis positional milling machines are easier to learn and use if the operator is a beginner.

Specification and maintenance of mini 5 axis milling machines

Because of variations in manufacturers and models, these general specifications might help buyers select the right machine for their needs.

• Worktable

Consider the material, dimensions, and holding capacity of the worktable. It is important to ensure that it can accommodate the size and weight of the workpieces. Moreover, check the worktable's maximum load, clamping options, and T-slots for workholding.

• Work Envelope

It is crucial to look at the work envelope's X, Y, and Z-axis travel. Ensure that the workpiece dimensions and the tool clearance can fit within the machine's working area.

• Spindle

Consider the spindle power, speed, and taper to ensure that it can handle the type of cutting tools and materials to be machined. Also, take note of the spindle's maximum speed, which affects the cutting efficiency.

• Tool Changer

Check the tool changer's capacity and type to ensure that it can accommodate the required number and types of tools for the machining operations.

• Drive System

Consider the drive system, such as servo motors and ball screws, to ensure the machine's positioning and cutting accuracy. Pay attention to the drive system's rapid traverse rates for efficient tool change and movement between machining operations.

• Control System

Check the control system, including the CNC controller and software, to ensure it supports the required programming capabilities and interface for easy operation and integration.

• Coolant and Chip Management

Check the coolant system for spindle and cutting tool cooling, as well as chip management for effective chip evacuation during machining to ensure workpiece quality and machine performance.

Regular maintenance is crucial to ensure the mini 5-axis CNC milling machine operates smoothly and achieves its expected service life. Here are some maintenance tips.

• Cleaning

Regularly clean the machine's surfaces and work area to remove debris, dust, and oil buildup. This will help prevent contaminating the workpiece and maintain the machine's performance.

• Lubrication

Lubricate the machine's moving parts, such as the slides, ball screws, and bearings, according to the manufacturer's instructions. Proper lubrication reduces friction and wear, ensuring the machine's positioning accuracy and prolonging its lifespan.

• Tool Inspection and Calibration

Regularly inspect cutting tools and holders for damage and wear, and replace them as needed. Also, calibrate the machine's tool length and diameter offsets to ensure machining accuracy. Proper tool maintenance and calibration will help achieve high-quality machining results.

• Electrical System Inspection

Periodically inspect the electrical system for loose connections and signs of wear. Ensure the safety of the electrical components. Also, check and replace worn cables and wiring to maintain reliable power and signal transmission.

• Coolant System Maintenance

Regularly maintain the coolant system by monitoring the coolant levels and quality. Clean the coolant tank and filters to ensure proper cooling and lubrication during machining.

• Backup and Software Updates

Regularly backup machining programs and parameters to prevent data loss. Additionally, keep the machine's control system and software up to date by installing recommended updates. This helps ensure optimal performance and system stability.

The machine's ability to work with different types of materials makes it ideal for use in various art and design fields.

How to choose 5-axis mini milling machines

When choosing a 5-axis mini milling machine, it is important to consider the following factors:

• Work envelope size: The machine's maximum workpiece dimensions must be smaller than the machine's working area. It is essential to consider the part's size that the business expects to machine. This is because an oversized machine is not cost-effective. Similarly, an undersized machine will not be able to handle the workload.
• Spindle speed and power: The spindle speed is typically measured in revolutions per minute (RPM). It is important to choose a machine that has a spindle speed that matches the material being machined. Also, the power of the spindle and motor should be enough to handle the cutting tool and material.
• Axis movement: The 5-axis machine should be able to move in all five axes. The machine must be able to rotate and tilt the workpiece in addition to the three linear axes. The more the machine can move, the more complex the parts it can create.
• Control system and software: It is important to choose a machine with intuitive control software that can be easily programmed and operated. This ensures the machine operator can efficiently use the machine.
• Accuracy and repeatability: The machine's accuracy and repeatability affect the quality of the machined parts. It is important to select a machine with a high level of accuracy and repeatability, which ensures consistent and precise machining performance.
• Tool capacity and automation: It is important to choose a machine with an appropriate tool capacity to handle the required cutting tools and workpiece features. The machine should also support automation solutions such as tool changers and robotic loading to improve efficiency and productivity.
• Budget and cost of ownership: The initial cost of the machine is an important factor to consider. It is important to choose a machine that meets the business's requirements and budget. Also, it is important to consider the machine's cost of ownership, which includes maintenance, tooling, and energy costs.

Q2: What are the advantages of a 5-axis CNC milling machine?

A2: Many 5-axis machines have the same advantage of 3-axis and 4-axis machines, but they can work on more complex parts.

Q3: What is the difference between a 5-axis and a 5-axis universal milling machine?

A3: The 5-axis universal mill can rotate vertically and horizontally in more than one place. The 5-axis mill can only rotate in one place.
