Alas
Correct Answer
A. Kepala lepasExplanation
The correct answer is "kepala lepas." The given image shows a part of a lathe machine, which is the headstock. The headstock is the main component of a lathe machine that holds the workpiece and rotates it. It is responsible for providing power to the workpiece and controlling its speed. The headstock can be detached or removed from the lathe machine for maintenance or to accommodate different attachments or tools. Therefore, the correct answer is "kepala lepas," which translates to "detachable head."Rate this question:

Jenis mesin frais yang memiliki sumbu/spindle tegak lurus terhadap benda kerja adalah…
-
Mesin Frais Horizontal
-
Mesin Frais Vertikal
-
Mesin Frais Universal
-
Mesin Frais Hexagonal
Correct Answer
A. Mesin Frais VertikalExplanation
Vertical milling machines have a spindle that is perpendicular to the workpiece. This means that the cutting tool moves up and down along the Z-axis, allowing for vertical milling operations. Horizontal milling machines, on the other hand, have a spindle that is parallel to the workpiece, enabling horizontal milling operations. Universal milling machines have the ability to perform both vertical and horizontal milling operations. Hexagonal milling machines do not exist, so the correct answer is Vertical Milling Machine.Rate this question:

Yang bukan merupakan alat potong pada mesin bubut adalah…
-
Pahat
-
Countersink
-
Reamer
-
EndMill
Correct Answer
A. EndMillExplanation
An end mill is not a cutting tool used in a lathe machine. It is a type of milling cutter used in milling machines. The other options - pahat (tool bit), countersink, and reamer - are all cutting tools commonly used in lathe machines. However, an end mill is used for milling operations, where the cutting tool rotates against a stationary workpiece to remove material and create a desired shape or profile.Rate this question:

-
Collet
Correct Answer
A. ColletExplanation
A collet is a tool used in milling machines to hold the workpiece securely in place. It is a cylindrical sleeve with a tapered inner surface that matches the taper of the machine's spindle. The collet is tightened around the workpiece, providing a strong grip and ensuring precise machining. This tool is commonly used in milling operations to hold round or cylindrical workpieces, allowing for accurate and efficient cutting.Rate this question:

Kepala Pembagi
Correct Answer
A. Kepala PembagiExplanation
The correct answer is "Kepala Pembagi". Kepala Pembagi is a tool used in milling machines for the process of creating grooves and gears. It is specifically designed to divide the workpiece into equal parts, allowing for precise and accurate machining. This tool is commonly used in industries such as automotive and manufacturing, where the creation of grooves and gears is essential for the production of various components.Rate this question:

Yang bukan merupakan bagian utama mesin bubut adalah…
-
Kepala Tetap
-
Cekam
-
Meja Kerja
-
Kepala Lepas
Correct Answer
A. CekamExplanation
The correct answer is "Cekam". The other three options, namely "Kepala Tetap", "Meja Kerja", and "Kepala Lepas" are all essential parts of a lathe machine. The "Kepala Tetap" refers to the fixed headstock, which holds the workpiece in place. The "Meja Kerja" is the worktable where the workpiece is mounted and rotated. The "Kepala Lepas" is the removable headstock, which allows for the attachment of different tools and accessories. On the other hand, "Cekam" refers to a chuck, which is a clamping device used to hold the workpiece securely in place during machining. While a chuck is commonly used in lathe machines, it is not considered a primary component of the machine itself.Rate this question:

Rotary Table
Correct Answer
A. ArborExplanation
The correct answer is "Arbor." An arbor is a tool used in milling machines to hold and rotate cutting tools. It is a cylindrical shaft that is inserted into the spindle of the milling machine and secured with a drawbar. The arbor provides support and stability to the cutting tool, allowing it to rotate and remove material from the workpiece. It is an essential component in milling operations, ensuring precise and accurate cutting.Rate this question:
