What is portable mini drill?
Normally machines are of fixed type and portable type depending on the size, weight, shape and utility. Small weighing simple shaped machines are portable machines. A small size drilling machine which can be taken to different working places conveniently is termed portable drilling machine. The simplest available machine widely using as a hand tool for making holes are called drill guns.
Is spot facing and drilling operations can be done on the same machine?
yes... spot facing can be done useing a drilling machine. for more info just download drill press text book.ppt @google cheers....
What is definition of portable drilling machine?
One that can be picked up (single-handedly or not) and moved to the work, rather than being bolted to a bench or the workshop floor. Some portable drilling-machines have magnetic bases, for use in steel-fabrication tasks.
What is rotating weight in drilling operation?
Rotating weight in drilling operations refers to the portion of the weight of the drill string that is effectively transferred to the drill bit while it is in motion. It is calculated by considering factors like the total weight of the drill string, the buoyancy effect of the drilling fluid, and the friction encountered during rotation. This weight is crucial for maintaining optimal drilling performance, as it influences the rate of penetration and the ability to break rock. Proper management of rotating weight helps to enhance drilling efficiency and reduce wear on the drill bit.
What is the function of a derrick on an oil rig?
A derrick on an oil rig serves as a tall structure that supports the drilling equipment used to extract oil and gas from underground reservoirs. It provides the necessary height for the drilling apparatus, allowing for the insertion and removal of drill pipes and casings. Additionally, the derrick aids in the safe handling of heavy equipment and materials, ensuring efficient and safe drilling operations. Ultimately, it is a critical component for facilitating the drilling process in offshore and onshore oil extraction.
What are the different kinds of drilling machine?
Drilling machines are designed for drilling holes using a range of drill bit types. Drilling machines are normally stand alone machines and are not portable.
What makes the simultaneous rotation of the spindle and the feed motion possible on drilling machines?
The simultaneous rotation of the spindle and the feed motion on drilling machines is made possible by the arrangement of gears and mechanisms within the machine. These components work together to transfer power from the motor to both the spindle for rotation and the feed mechanism for moving the drill into the material being drilled. This coordinated movement allows for efficient drilling operations to take place.
What simple machines are used in mining and drilling?
A drill
What is the difference between drilling and boring machines?
Drilling machines are used to create holes in a workpiece, while boring machines are used to enlarge or smooth out existing holes. Drilling machines typically use rotating drill bits to create holes, while boring machines use single-point cutting tools to enlarge existing holes to precise dimensions.
What is a steam drill?
A steam drill is a type of drilling machine that is powered by steam. It is commonly used for drilling holes in rocks, especially in mining and tunneling operations. The steam drill revolutionized drilling processes by increasing the speed and efficiency of drilling operations.

What is automatic drilling machine?
An automatic drilling machine is a specialized equipment designed to perform drilling operations with minimal human intervention. It uses programmable controls to automate processes such as positioning, drilling speed, and depth, enhancing precision and efficiency. These machines are commonly used in manufacturing and construction for tasks like creating holes in various materials, including metal, wood, and plastic. By automating drilling, they help reduce labor costs and improve production rates.
What is PDL in drilling operations?
PDL in drilling operations stands for "Planned Depth Limit." It refers to the maximum depth that a drilling operation is intended to reach based on geological assessments and engineering calculations. The PDL helps guide drilling activities, ensuring that operations remain within safe and economically feasible boundaries while also optimizing resource extraction. Adhering to the PDL is crucial for managing risks and costs associated with drilling projects.

What type of jobs or operations can be carried out on a pillar drilling machine?
. Lists the operation which can be carried out by using a pillar drilling machine.
Is drilling mud a chemical?
Yes, it is. Drilling fluids, the circulating fluid for drilling operations, is a mixture of the fluid, the solid and chemical agents. It is usually known as the "mud" or the "blood of drilling" deriving from its distinctive significance.
What is the purpose of a bore hole door and how does it function in the context of drilling operations?
The purpose of a bore hole door is to control the flow of drilling fluid and prevent debris from entering the bore hole during drilling operations. It functions by opening and closing to allow the drilling fluid to circulate and maintain pressure, while also sealing off the bore hole to protect the integrity of the drilling process.
