CNC vertical lathe is a commonly used CNC machine tool. Its main feature is the use of vertically installed tool holders and axially arranged workpieces. The tool holders in CNC vertical lathes are divided into two types: front-mounted and rear-mounted. Next, their differences and applications will be introduced in detail.

1. Front tool holder

The front tool holder is a common processing method in the new generation of CNC vertical lathes. Compared with traditional CNC vertical lathes, its cutting efficiency is higher and more stable. The front tool holder can install multiple tools, and the cutting range of the tools is more flexible. It can complete the processing of both outer and inner circles. During the machining process, the spindle of the front tool holder is in a high-speed rotating state, so its machining efficiency is high and a large amount of production work can be completed. In addition, due to the fast tool change speed of the front tool holder, the front tool holder can complete more processes in the same processing time.

2. Rear tool holder

Rear-mounted tool holder is also a common processing method of CNC vertical lathe. Compared with the front-mounted tool holder, its structure is simpler and the cost is cheaper. There are fewer tool positions inside the rear tool holder, which can only complete a single processing process, so its flexibility is poor. However, when processing small batches of workpieces of different shapes, the rear tool holder has certain advantages. In addition, in the process of fine machining, the rear tool holder is usually more suitable than the front tool holder.

3. Selection of front and rear tool holders

When choosing a front or rear tool holder for a CNC vertical lathe, you need to consider the specific processing needs. If you need to complete multiple, flexible machining processes and the workpiece shape rules are complex, you should choose the front tool holder. If a single, high-precision machining process is required, or a high degree of control over cutting quality is required during the machining process, the rear tool holder should be selected.

To sum up, both the front tool holder and the rear tool holder have their advantages and disadvantages, and the specific choice should be judged based on the actual processing needs. No matter which tool holder is chosen, CNC vertical lathe is a modern machine tool that can complete the machining process efficiently and flexibly.
