FAQ Angle Plates

Question: What is an angle plate used for?

Answer: An angle plate is a tool used in machining and metalworking to hold workpieces securely at specific angles during various operations such as drilling, milling, or grinding. It provides a stable reference surface for accurate positioning and alignment.
Examples of how an angle plate is used:
1. Holding a workpiece at a 90-degree angle to perform drilling or milling operations on its sides or edges.
2. Aligning and clamping multiple workpieces together at a specific angle to create complex assemblies or welded structures.
3. Establishing a perpendicular reference surface for checking or aligning the squareness of components.
4. Creating inclined surfaces or beveled edges by tilting the angle plate to the desired angle. in case using tilting angle Plate
5. Supporting workpieces during precision measurement or inspection to ensure accurate and consistent results.
Overall, an angle plate is a versatile tool that aids in workholding, alignment, and achieving specific angles in metalworking and machining processes.

Question: What are the types of angle plate?

Answer: There are several types of angle plates available, each designed to suit specific applications and requirements. Here are some common types of angle plates:
1. Plain Angle Plate: This is the most basic type of angle plate, consisting of a simple flat plate with two perpendicular machined surfaces. It is used for general workholding and setup applications where a flat reference surface is needed.
2. Slotted Angle Plate: Slotted angle plates have additional slots or T-slots machined into the flat surfaces. These slots allow for the attachment of clamps, bolts, or other fixtures to secure workpieces in various positions and orientations.
3. Tilting Angle Plate: Tilting angle plates, also known as adjustable angle plates, feature an adjustable mechanism that allows the plate to be tilted or swiveled to different angles. This type is used for creating inclined surfaces, beveled edges, or specific angular setups.
4. Sine Angle Plate: Sine angle plates have accurately machined angular surfaces that allow for precise angular adjustments. They are commonly used in machining applications that require precise angles for grinding, milling, or inspection operations.
5. Universal Angle Plate: Universal angle plates combine the features of plain angle plates, slotted angle plates, and tilting angle plates. They offer versatility in terms of clamping options, adjustability, and angle-setting capabilities. This type is ideal for complex setups and multi-axis machining.
6. Magnetic Angle Plate: Magnetic angle plates have a strong magnetic base that securely holds ferrous workpieces in place. They eliminate the need for clamping or bolting, providing quick and convenient workholding solutions.

Question: What is the difference between a surface plate and an angle plate?

Answer: A surface plate and an angle plate are both precision tools used in machining and metrology, but they serve different purposes and have distinct features. Here are the key differences between a surface plate and an angle plate:

Purpose
Surface Plate: A surface plate is primarily used as a reference surface or measuring, inspecting, and flatness checking of workpieces and tools. Angle Plate: It is primarily used for workholding and setup applications. It provides a rigid and stable platform for holding workpieces at specific angles or orientations during machining operations.

Design
Surface Plate: Surface plates are large, flat, and typically rectangular or square in shape. They are made from high-quality materials like granite or cast iron.
Angle Plate: Angle plates are flat plates with two perpendicular machined surfaces, creating a 90-degree angle. They are typically made from materials like cast iron or steel.

Usage
Surface Plate: Operators use surface plates in conjunction with precision measuring tools like height gauges, dial indicators, and surface gauges.
Angle Plate: Angle plates are commonly used in conjunction with other workholding devices like vises, clamps, or fixtures to hold workpieces securely and accurately during milling, drilling, grinding, or assembly processes.

Question: What are the advantages of angle plate?

Answer: 1. Accuracy: Angle plates provide a stable and accurate reference surface for machining operations.
2. Strength: Angle plates are made of strong materials, such as cast iron or steel. This makes them able to withstand the forces applied during machining or assembly operations.
3. Versatility: Angle plates are available in a variety of sizes and shapes, to accommodate different workpieces and applications.
4. Reusability: Angle plates are typically reusable, which can save time and money.
5. Cost-effectiveness: Angle plates are relatively inexpensive, making them a cost-effective way to improve the accuracy and precision of metalworking operations.
