Radial Drilling Machine

Radial drilling machines are designed to drill holes in very strong materials and heavier workpieces, which are usually not possible with ordinary drilling machines. Compared with traditional drilling machines, these tools have higher accuracy and stability. These devices are widely used in the metal manufacturing industry because it can make holes of different sizes in hard metals. Since most conventional drilling machines are very unstable, they rarely provide the required stability and strength. These machines are usually used with CNC routers, which further simplifies its use and efficiency. CNC controlled equipment has extensive experience because the tool can perform multiple tasks. In this article, we will tell you everything you need to know about radial drilling machines, their applications, structure, and benefits.

Radial Drilling Machine Introduction

The radial drilling machine is special. It usually has a drill bit that slides alongside the radial arm. The arm can be lifted, lowered, or rotated on the vertical rod to adjust the position of the drill bit above the part. Radial drilling operations support a wide range of different materials that include but are not limited to steel, cast iron, wood and plastic. Generally speaking however, it is  most common in metal processing.

The main components of the radial drilling machine are the base, the inner column, the outer column, the upper arm (rocker arm), the spindle box, and the table. Depending on the model, the inner column is fixed at either end of the base. The outer column rotates all the way around the inner column (360 degrees). The rocker arm has a sleeve on the outer column that can move up and down. The arm cannot only rotate together with the outer column around the inner column because the screw is located in the outer column and the lifting nut is fixed on the rocker arm. In the spindle box, you can usually find the motor, spindle and drive, feed, and speed change mechanism. The spindle box is operated by the handwheel to move along the rocker arm on the horizontal guide rail.

Radial drilling machines use rotating cutting tools, also known under the name ‘drill bits’. They have a large gear head that can move along the arm and radiate out of the column of the drilling machine. The radial arm swings and removes the drill bit to place the part that is being machined at the base of the radial drilling machine. This swinging motion also makes it possible to drill holes at various points on the workpiece without actually moving it.


Advantages of a Radial Drilling Machine

Radial drilling machines come with a lot of benefits for the operator. It is very compact in size and can be used very quickly and conveniently. It is also recognized as one of the most versatile machines because it can easily counter holes, punch holes, and even grind out large particles. The device has long arms that can be repositioned according to user requirements. Using this machine can also handle large pieces of material. These devices are designed to perform most tasks efficiently, so users require less work. Since the arm can be extended to a considerable length, it can also perform a variety of movements. It is also very strong and durable. It can perform various functions easily and quickly. The device is resistant to adverse conditions. These drilling machines are very common in the printing, automotive, engineering, and other industries, because of their accuracy and efficiency. 

Radial drilling machines ensure smooth spindle rotation and reduce or prevent angular spindle movement. They can accommodate drill bits of specific diameters, that we also call chucks. To perform drilling operations, it rotates at specific revolutions per minute. Radial drilling machines are very useful for machining, as they have a variety of applications and functions, such as drilling, boring, tapping, reaming, lapping, lapping, tightening, counterboring, point hole processing, and many more. It is easy to drill holes of various sizes (30 mm to 100 mm) in a radial direction. Besides, various radial drilling machines with relatively large capacity are also widely available anywhere around the world.
