Drilling machines are one of the most commonly use tools in mechanical workshops. They are use to create holes in different types of materials, includ metal, wood, plastic, and more. Depend on the specific requirements of a project, different types of drill machines may be use. In this post, we will explore the different types of drill machines that are commonly use in mechanical workshops.
Bench Drilling Machine
A bench drilling machine, also known as a pillar drill, is a type of drilling machine that is mount on a bench or a stand. It is used to drill small to medium-size holes in different materials.
The machine consists of a base, a column, a table, a spindle, and a drill head. The spindle is driven by an electric motor and can be adjust for speed, depth, and feed. The table can be adjust for height and can be tilte for angular drill.
Radial Drilling Machine
A radial drilling machine is a type of drilling machine that is designe for heavy-duty drilling operations. It consists of a vertical column that supports a horizontal arm. The arm can be rotate around the column and can be adjust for height and reach.
The spindle is locate at the end of the arm and can be adjust for speed, depth, and feed. This type of drill machine is ideal for drill large and heavy workpieces that cannot be move to a bench drill machine.
Magnetic Drilling Machine
A magnetic drilling machine, also known as a mag drill, is a type of drilling machine that uses an electromagnetic base to attach itself to the workpiece. It is use for drilling holes in large and thick materials, such as steel plates and beams.
The machine consists of a base, a column, a motor, a spindle, and a drill bit. The motor drives the spindle, which is held in place by the magnetic base. The machine can be adjust for speed, depth, and feed.
Pillar Drilling Machine
A pillar drilling machine is a type of drilling machine that is similar to a bench drilling machine. However, it is larger and more powerful. It is use for drilling medium to large-size holes in different materials.
The machine consists of a base, a column, a table, a spindle, and a drill head. The spindle is driven by an electric motor and can be adjust for speed, depth, and feed. The table can be adjust for height and can be tilte for angular drill.
Deep Hole Drilling Machine
The process of deep hole drill involves several steps, starting with the selection of the appropriate drill bit for the material being drill. The drill bit is then attach to the spindle and position above the workpiece. As the spindle rotates, the drill bit slowly advances into the material, cutting away tiny chips with each rotation. The coolant system plays a crucial role in this process, as it helps to cool the drill bit and workpiece, and flushes away the chips to prevent clogging and damage to the drill bit.
In addition to the base, column, spindle, and drill bit, some deep hole drilling machines may also include a workpiece support system, which helps to stabilize the workpiece and prevent vibrations during the drilling process. Other features may include automatic chip removal systems and advanced control systems that allow for precise adjustments of the drilling parameters.
Conclusion
Drilling machines are essential tools in mechanical workshops for creating holes in different types of materials. They come in different types and sizes, each with its own set of advantages and disadvantages.
The most commonly used types of drilling machines in mechanical workshops are the bench drilling machine, radial drilling machine, magnetic drilling machine, pillar drilling machine, and deep hole drilling machine. Depend on the specific requirements of a project, different types of drill machines may be use.
If you are looking to purchase drilling machines for your mechanical workshop, you can buy power drills online from various suppliers and manufacturers. It is important to consider your specific needs and requirements before purchasing a drilling machine to ensure that you get the best machine for your project. With the right drilling machine, you can achieve high-quality drilling operations with ease and efficiency.
