Vertical Machining Centre Buying Guide
Some CNC buyers waste money by investing in vertical machining centres far beyond the demands of their projects. Others invest in “cheap” machines only to find they sacrificed quality, repeatability, and accuracy to save money.
Both overspending and underspending on your vertical machining centre can cut into your profits – which defeats the real purpose of any machine investment. The goal, after all, is to maximise profits and ROI.
Before buying a vertical machining centre, take a moment to assess your machining needs. Consider the specifics of your machining process – the operations you want to perform, the production goals you want to achieve, and the materials you’ll be cutting. Your chosen vertical machining centre (VMC) should have suitable spindle speeds, table load capacity, maximum tool weight, and tooling capacity for your requirements.
Let’s review all the factors you should consider before buying a vertical machining centre.
1. Why buy vertical machining centres from ETG?
As an ETG customer, you can look forward to the following benefits when purchasing your vertical machining centre through us:
2. Factors to consider when buying a vertical machining centre
Consider these factors when selecting your vertical machining centre:
Some VMCs limit tool capacity to only 20 or 24 tools, stifling the flexibility and variety needed to machine efficiently.
However, larger machines, like our Quaser MF 400 Cell – C/U with its 120 magazine positions, can accommodate more tools and enhance versatility.
Furthermore, machines with higher tool capacity streamline setup and reduce time spent on tool changes, contributing to overall productivity.
Tool weight plays an essential part in the efficiency of the machining process. Larger, longer, heavier cutting tools are the most efficient as they reduce cutting times. However, many vertical machining centres have a low maximum limit for tool weight.
Limiting the use of these heavier tools can slow down the production process and increase the cost per part.
A VMC with a higher tool weight capacity allows for heavier and more versatile tool combinations.
Power, torque, and speed
Cutting at high spindle speeds isn’t just about removing metal quickly but also about creating top-notch surface finishes.
However, speed is not the only factor you need to consider.
A machine’s performance in terms of power and torque is also crucial for machine shops working with various materials. Here are some scenarios that might require a machine with high torque:
- Heavy cutting operations: When machining dense materials like titanium or hardened steel, high torque is needed to power through the material efficiently.
- Large diameter tools: Using larger diameter cutting tools, such as face mills or drills, requires high torque to maintain cutting stability and prevent tool deflection.
- Deep cavity machining: In applications where the cutting tool needs to reach deep into a workpiece, high torque helps maintain cutting performance and chip evacuation.
- Tough materials: Working with tough or difficult-to-machine materials, like Inconel or high-strength alloys, requires extra torque for effective material removal.
The key is having a versatile VMC that can handle all your requirements effortlessly – power, torque and speed.
Table load capacity
Table load capacity determines the maximum size and weight of the workpieces that the VMC can accommodate.
This is crucial, especially if you regularly work with large or heavy parts. If the table load capacity is insufficient for your intended applications, you may face several limitations and challenges:
- Workpiece size: Exceeding the table load capacity can lead to poor machining performance, decreased accuracy, and potential machine damage.
- Tool life: Excessive loads can accelerate tool wear and reduce tool life, leading to more frequent tool changes. Choosing a VMC with an appropriate table load capacity helps maintain tool life and cutting performance.
