Machine Tool Technology General Quiz

When using a surface grinder, the most important safety precaution is to wear safety glasses. This is because a surface grinder involves the use of rotating abrasive wheels that can generate sparks, debris, and particles that can potentially cause eye injuries. Safety glasses provide a protective barrier for the eyes, preventing any foreign objects from entering and causing harm. It is crucial to prioritize eye safety while operating a surface grinder to avoid any potential accidents or injuries.

The statement suggests that dressing the Surface grinder should only be done 2 times a week. However, the correct answer is False because the frequency of dressing the Surface grinder depends on various factors such as the type of material being ground, the condition of the grinding wheel, and the desired precision of the grinding process. It is important to dress the grinder as often as necessary to maintain optimal performance and achieve the desired results.

Wood and plastic can be used on a CNC milling machine because these materials are commonly machined using this type of equipment. CNC milling machines are versatile and can handle a wide range of materials, including wood and plastic. These machines use computer-controlled movements to precisely cut and shape the material, making them suitable for various applications in woodworking and plastic fabrication. Therefore, the statement is true.

"Swinging the head" refers to the movement of the milling machine's head, which can be adjusted in different angles to perform various cutting operations. This movement allows the milling machine to create different types of cuts and shapes on the workpiece. Therefore, the correct answer is milling machine.

The distance you move the far right knob on a Surface grinder is 1 thousandth. This means that when adjusting the far right knob, you move it by a distance of 0.001 inches. This adjustment is very small and precise, allowing for fine-tuning and precision in the grinding process.

Dressing a surface grinder involves removing any buildup or irregularities on the grinding stone to ensure optimal performance. It is necessary to dress the surface grinder each time the machine is started up because the grinding stone may have become dull or clogged during the previous use. By dressing the grinder at the start of each session, the operator can ensure that the grinding stone is in the best condition for accurate and efficient grinding.

Angle gauges are precision measuring tools used to determine the angle of a surface or object. In order to make angle gauges, several tools are required. A hacksaw is used to cut the desired shape and size of the gauge. A drill bit or milling machine is used to create holes or slots in the gauge for specific measurements. A surface grinder is used to ensure that the gauge has a flat and smooth surface. A file is used for shaping and smoothing the edges of the gauge. Finally, a paint brush is used to apply a protective coating or color to the gauge.

The correct answer is 250 thousandths and 375 thousandths. When drilling the release hole on an Angle Gauge using a milling machine, the X and Y axis measurements should be 250 thousandths and 375 thousandths respectively. These measurements ensure accurate drilling and alignment of the release hole on the Angle Gauge.
