On Vertical Boring Machines

The size of vertical boring machines is usually big. This is because vertical boring machines usually have to use rotating pieces to a horizontal table. As the name shows, the function has a close relationship with borers. With the use of vertical boring mills, the borers being processed are allowed to travel in a horizontal direction.

What Are Vertical Boring Machines?

They are specialized in large-scale industrial operations. The main function of a vertical boring machine is for creating a hole in the workpiece. Unlike drilling and reaming machines, a boring machine aims to enlarge an existed hole and make the size fit the manufacturer's requirements.

When an object is worked on, it has to be attached to the machine to ensure the accuracy and precision of the result.
 

Features of Vertical Boring Machines

Before making your decisions, here are some features of vertical boring mills that you may want to know.
 

Corrosion-resistance

The vertical boring machine is made of cast iron and stainless. Besides the advantage of durability, it is also corrosion-resistant. Since the outer wall of the machine has been through special processed, it lasts longer under higher or lower temperatures.
 

Longer Service Life

With high efficiency and durable working components, the lifetime of vertical boring machines is longer than the older versions. Although the initial cost of planning a new working environment for vertical boring mills cannot be avoided, the longer durability makes them a better choice and saves money for the users.
 

Energy Efficiency 

As manufacturing technology improves, the working efficiency shows a clear increase. Compared to drilling or reaming machines, vertical boring machines can achieve the same level of task with less energy. That is to say, the electric motors need less energy to run. The result is that you will be charged less in your electric bill.
 

Cost-effectiveness

Besides your electric bill, the durability of the working components and longer lifetime are all reasons that can save money for users. In a long run, vertical boring machines show the advantages money-wise.

Major Differences between Horizontal and Vertical Boring Machines

1. For horizontal boring machines (or floor type boring mills), the workpiece is rotated around an X-axis (or horizontal turning) while the boring head moves horizontally; but for the workpiece being worked on a vertical boring machine, it is rotated around a Y-axis (or vertical turning). Its boring head moves linearly.
2. Both horizontal and vertical boring machines use non-rotating tools by using a cords rail that is mounted on the turret slide.
3. However, the horizontal boring mills are more versatile since they are capable of performing facing, boring, shaping, tapping, drilling, milling, and contouring process. That is why horizontal type becomes very popular among manufacturing companies. Also, its setup process is quite similar to that of lathe and standard milling machines.
4. On the side of vertical boring machines, the setup time required for workpieces with a larger diameter and heavier weight is quicker and more convenient. Also, there is no need to worry if the heavy workpiece bends your machine. This is because there is no overhang as in the lathe spindle.
5. The third advantage is that the diameter of the table may be designed as a user’s wish. It can be as large as possible to support heavy and large workpieces. The vertical working mode gives the workpieces more space to be worked on. Although the versatility is not as good as horizontal boring machines, a vertical type can be applied with many types of accessories to increase its productivity.

Differences among Manufacturing Process

Boring, drilling, and reaming are the three most used processing methods. All three methods involve creating a hole in a workpiece. It may be useful for readers to know the differences between the three to know.
 

Boring

This kind of cutting process aims to enlarge an existing hole, which can be done by
the drilling process. Usually, the process involves the use of a boring head or a single-head boring tool. Unlike drilling, the purpose of applying boring is to enlarge the hole but not create a new one.

Lathe, milling machine, horizontal/vertical boring machine can all be used for performing the boring processes. Each works slightly differently but serves the same goal – to enlarge an existing hole.
 

Drilling

Drilling uses a drill to create a round hole in a workpiece. It applies a rotary cutting tool to achieve the goal. Since the major goal is to create a hole in a workpiece, it scrapes a certain amount of material based on how large the hole is. Most manufacturing companies press the rotary drill against the workpiece, which means that the drilling machine applies pressure on the workpiece by the drilling machine tool to scrape out the material.

In the past, the drilling process could only be applied to soft material. This was because the drilling tools at the time were not sturdy and durable enough to perform the drilling process on hard workpieces. Nowadays, as technology develops and manufacturing techniques improved, drilling, reaming, and boring process on metal are common.
 

Reaming

The goal of reaming is similar to boring, but it aims to smoothen the interior wall of the existing hole. It achieves the goal by applying a rotary cutting tool (in a boring process, it uses a boring tool). The rotary cutting tool is also known as a reamer. Reaming removes less material from the workpiece since its major goal is only to create smooth walls. Most manufacturing companies perform reaming by applying a milling machine or drill press.
