Q & A

What is the primary function of a jig in manufacturing?

The primary function of a jig is to securely clamp the workpiece and accurately position the cutting tool during drilling operations.

What are the essential requirements of a drill jig?

Essential requirements include quick and accurate location of workpieces, prevention of wrong loading, chip clearance, swarf removal, lightweight design, and the ability to withstand cutting forces.

What materials are commonly used to manufacture jigs?

Jigs are commonly made from hardened steel or cast iron due to their resistance to wear, corrosion, and their ability to absorb vibrations.

How does a template drill jig differ from a plate drill jig?

A template drill jig is simpler and typically made of metal or wood with pre-drilled holes for quick drilling, while a plate drill jig incorporates bushings for guided drilling and is suitable for mass production.

What type of jig is suitable for drilling on multiple faces of a workpiece?

The box drill jig is designed for drilling operations on multiple faces of a workpiece and allows for more complex drilling tasks.

Can you explain the function of the leaf or latch type jig?

The leaf or latch type jig allows for easy loading of workpieces and is particularly suitable for complex geometries, using a latch mechanism for secure clamping.

What is the purpose of chip clearance in drill jigs?

Chip clearance is essential to ensure that metal chips and swarf do not obstruct the drilling operation, allowing for smooth and uninterrupted cutting.

What role does dimensional accuracy play in the performance of jigs?

Dimensional accuracy is crucial as it directly influences the accuracy of the drilled holes in the workpiece, ensuring that the final product meets specifications.

How does the angle plate jig facilitate drilling operations?

The angle plate jig allows for drilling operations at a 90-degree angle, providing a groove for the drill's passage and ensuring precise alignment.

What type of workpieces is the pot drill jig primarily used for?

The pot drill jig is primarily suitable for circular workpieces and includes features for chip clearance and secure clamping.
