parallel blocks Supplier

Finding a reliable parallel blocks supplier can be challenging. This guide provides key factors to consider, the types of parallel blocks available, and how to select the right supplier to meet your specific needs and ensure precision in your machining operations. We'll explore materials, tolerances, and applications, helping you make an informed decision.

Understanding Parallel Blocks

What are Parallel Blocks?

Parallel blocks are precision-ground rectangular or square blocks made of hardened steel or other durable materials. They are used in machining, toolmaking, and inspection to provide a known and accurate height or reference surface. They are typically sold in matched pairs or sets to ensure that their heights are identical within very tight tolerances.

Why are Parallel Blocks Important?

Parallel blocks are essential for:

Setting up workpieces in machine tools: Ensuring accurate alignment and height.
Measuring and inspecting parts: Providing a precise reference for measurements.
Toolmaking: Creating accurate tooling and fixtures.
General shop use: Spacing, supporting, and leveling workpieces.

Factors to Consider When Choosing a Parallel Blocks Supplier

Material

The most common materials for parallel blocks are:

Hardened Steel: Offers excellent durability and wear resistance. Common grades include tool steel like O1 or A2.
Stainless Steel: Provides corrosion resistance, suitable for applications where rust is a concern.
Carbide: Offers exceptional hardness and wear resistance, ideal for high-precision applications. However, carbide parallel blocks are generally more expensive.

Tolerance

Tolerance refers to the allowable variation in the dimensions of the parallel blocks. Smaller tolerances indicate higher precision. Common tolerance grades include:

±0.0002' (0.005 mm): High precision, suitable for demanding applications.
±0.0005' (0.013 mm): Medium precision, suitable for general shop use.
±0.001' (0.025 mm): Standard precision, suitable for less critical applications.

Size and Quantity

Consider the range of sizes you need and the quantity required. Most parallel blocks are sold in sets, but you may also need individual blocks for specific applications. Common sizes range from 1/8' to 2' in thickness.

Reputation and Reliability

Choose a parallel blocks supplier with a proven track record of providing high-quality products and excellent customer service. Look for suppliers with certifications like ISO 9001, which indicates a commitment to quality management.

Types of Parallel Blocks

Standard Parallel Blocks

These are rectangular or square blocks with parallel faces. They are the most common type of parallel blocks and are used for a wide range of applications.

Adjustable Parallel Blocks

These blocks have an adjustable height, allowing for fine-tuning of the workpiece position. They are useful for setting up complex machining operations.

Angle Parallel Blocks

These blocks have angled faces, used for setting up workpieces at specific angles. They are often used in toolmaking and inspection.

Finding a Reliable Parallel Blocks Supplier

Online Marketplaces

Websites like Amazon, eBay, and specialized industrial supply marketplaces offer a wide range of parallel blocks from various suppliers. Check customer reviews and ratings to assess the supplier's reputation.

Industrial Supply Companies

Companies like MSC Industrial Supply, Grainger, and McMaster-Carr are established industrial suppliers that offer a wide selection of parallel blocks and other tooling. They typically provide detailed product specifications and technical support.

Direct Manufacturers

Purchasing directly from manufacturers can offer competitive pricing and customization options. Research manufacturers that specialize in precision measuring tools and have a good reputation for quality.

Questions to Ask a Potential Parallel Blocks Supplier

What materials are your parallel blocks made of?
What is the tolerance of your parallel blocks?
Do you offer any certifications or guarantees of quality?
What is your lead time for delivery?
What is your return policy?
Do you offer custom sizes or materials?

Maintenance and Care of Parallel Blocks

Proper maintenance will extend the life of your parallel blocks and ensure their accuracy.

Cleanliness: Keep parallel blocks clean and free of dirt, chips, and other contaminants. Use a clean cloth and mild solvent if necessary.
Storage: Store parallel blocks in a protective case or cabinet to prevent damage.
Handling: Avoid dropping or mishandling parallel blocks, as this can damage their precision-ground surfaces.
Calibration: Periodically check the accuracy of your parallel blocks using a calibrated measuring instrument.

Case Studies: Successful Applications of Parallel Blocks

Case Study 1: Precision Machining

A machine shop uses high-precision parallel blocks from a reputable parallel blocks supplier to accurately align workpieces in a CNC milling machine. This ensures that the parts are machined to the correct dimensions and tolerances, resulting in high-quality finished products.

Case Study 2: Toolmaking

A toolmaker uses adjustable parallel blocks to create a custom fixture for holding a workpiece during grinding. The adjustable height allows for precise positioning of the workpiece, resulting in accurate and repeatable grinding operations.

Conclusion

Choosing the right parallel blocks supplier and selecting the appropriate parallel blocks for your application is crucial for achieving precision and accuracy in your machining and inspection operations. By considering the factors outlined in this guide, you can make an informed decision and ensure that you have the right tools for the job.
