Wholesale parallel blocks

Parallel blocks are precision tools used to set up work in machining and other applications requiring accuracy and parallelism. This guide explores the different types of wholesale parallel blocks, their applications, factors to consider when purchasing, and how to use and maintain them properly to ensure optimal performance and longevity.

Understanding Parallel Blocks

What are Parallel Blocks?

Parallel blocks, also known as precision parallels, are hardened and ground steel or carbide blocks manufactured to extremely tight tolerances. They are designed to provide a perfectly parallel reference surface, essential for setting up workpieces in milling machines, lathes, and other precision equipment. These blocks allow for consistent and accurate positioning, significantly improving the quality of finished parts.

Types of Parallel Blocks

Various types of wholesale parallel blocks cater to different needs and applications. Here are some common types:

• Standard Parallel Blocks: These are rectangular blocks with parallel top and bottom surfaces. They come in various sizes and thicknesses.
• Thin Parallel Sets: These sets contain very thin parallels, often used for precision shimming and fine adjustments.
• Adjustable Parallel Blocks: These parallels can be adjusted to specific heights within a certain range, offering versatility.
• Angle Parallel Blocks: Designed with angled surfaces, these are used for setting up angled workpieces.

Applications of Wholesale Parallel Blocks

Wholesale parallel blocks are indispensable in a wide range of industries and applications:

• Machining: Setting up workpieces in milling machines, lathes, grinders, and other machine tools.
• Tool and Die Making: Ensuring accurate alignment and parallelism in tool and die assembly.
• Inspection: Providing a reference surface for inspecting the flatness and parallelism of parts.
• Assembly: Accurately positioning components during assembly operations.
• Quality Control: Verifying the accuracy of machining setups and finished parts.

Factors to Consider When Buying Wholesale Parallel Blocks

Choosing the right wholesale parallel blocks requires careful consideration of several factors:

Material

Parallel blocks are typically made of hardened steel or carbide. Steel blocks are more common and suitable for general-purpose applications. Carbide blocks offer higher hardness and wear resistance, ideal for demanding applications and abrasive materials.

Accuracy

Accuracy is paramount. Look for blocks with tight tolerances, typically measured in ten-thousandths of an inch (0.0001'). Ensure the blocks are certified to meet industry standards.

Size and Dimensions

Select sizes and dimensions that suit your specific application. Consider the size of the workpieces you'll be working with and the range of heights you need to achieve.

Set Configuration

Parallel blocks are often sold in sets. Choose a set that contains the range of sizes and thicknesses you need. Some sets may include additional accessories, such as fitted cases or height gauges.

Hardness

The hardness of the parallel block determines its resistance to wear and deformation. Higher hardness is generally desirable for long-term durability.

Cost

Consider your budget and balance cost with quality and performance. While cheaper options may be tempting, investing in high-quality parallel blocks can save you money in the long run by ensuring accuracy and reducing the risk of errors.

How to Use Parallel Blocks

Proper use of wholesale parallel blocks is crucial for achieving accurate results:

1. Cleanliness: Ensure the blocks and the work surface are clean and free of debris. Use a clean cloth or degreaser to remove any oil or contaminants.
2. Placement: Position the blocks strategically under the workpiece to provide stable support. Ensure the blocks are evenly spaced and aligned.
3. Securing: Use clamps or other workholding devices to securely hold the workpiece in place. Avoid over-tightening, which can distort the blocks or the workpiece.
4. Verification: Use a dial indicator or height gauge to verify the parallelism of the workpiece. Make adjustments as needed to achieve the desired accuracy.

Maintaining Parallel Blocks

Proper maintenance will extend the life of your wholesale parallel blocks:

• Cleaning: Regularly clean the blocks with a clean cloth and degreaser. Remove any oil, dirt, or debris.
• Storage: Store the blocks in a clean, dry place, preferably in a fitted case. Avoid storing them in contact with other tools or materials that could scratch or damage them.
• Inspection: Periodically inspect the blocks for signs of wear, damage, or corrosion. Replace any blocks that are damaged or worn.
• Rust Prevention: Apply a thin coat of oil or rust preventative to the blocks to protect them from corrosion.

Troubleshooting Common Issues

Even with proper use and maintenance, you may encounter some common issues with wholesale parallel blocks:

• Inaccurate Readings: This could be due to dirty blocks, worn blocks, or improper setup. Clean the blocks, inspect them for wear, and ensure the setup is correct.
• Slippage: Slippage can occur if the blocks are not properly supported or if the workpiece is not securely clamped. Ensure the blocks are evenly spaced and the workpiece is securely clamped.
• Damage: Damage can occur if the blocks are dropped or mishandled. Handle the blocks with care and avoid dropping them.
