More questions buyers ask
What are Crystal AA-177 V-blocks used for?
Crystal AA-177 V-blocks are precision metalworking tools used to securely hold cylindrical workpieces for marking, inspection, machining, and grinding operations. They ensure stability and accuracy for tasks requiring high precision.
What material are these V-blocks made of?
These V-blocks are made from high-quality tool steel that is hardened and ground to ensure high accuracy, durability, and resistance to wear and tear.
Are these V-blocks hardened and ground?
Yes, the 'Hardened & Ground' designation means they have undergone a heat treatment process to increase their surface hardness and have been precision ground to achieve a very flat, smooth, and accurate surface finish.
What is the accuracy standard for these V-blocks?
The Crystal AA-177 series V-blocks are manufactured as per the Indian Standard IS 2949-1992, which governs the specifications and accuracy for V-blocks.
Do the V-blocks come with clamps?
Yes, the Crystal AA-177 series includes specially designed clamps that fit into the V-blocks to securely hold the workpiece in place during operations.
Are these V-blocks sold as single pieces or pairs?
They are typically sold in matched pairs to ensure that both blocks are perfectly identical in size and accuracy, which is critical for many precision setups. Please check the product description for specific package contents.
What is the clamping diameter range for these V-blocks?
The clamping diameter range varies by model. For example, the 50x40x40mm model (AA-1771) supports diameters from 5-40mm, while larger models support larger diameters.
Are Crystal V-blocks suitable for professional machinists?
Absolutely. Crystal is a well-regarded brand in India for precision tools. These hardened and ground V-blocks are designed for professional use in machine shops, tool rooms, and quality control departments.
How do I ensure the longevity of my V-blocks?
To maintain their accuracy and lifespan, always clean the V-blocks before and after use, apply a light coat of rust-preventive oil for storage, and avoid dropping or hitting them.
Where can I buy genuine Crystal AA-177 V-blocks in India?
You can purchase genuine Crystal AA-177 V-blocks from authorized industrial suppliers and B2B marketplaces like Gearo. We provide a GST invoice, manufacturer's warranty, and deliver across India.
Who should choose the 50x40x40mm (AA-1771) V-block?
The 50x40x40mm model is ideal for small-scale precision work, hobbyists, and workshops that primarily handle smaller cylindrical parts with diameters up to 40mm.
Who should choose the 80x63x63mm (AA-1777) V-block?
The 80x63x63mm V-block is a versatile mid-range option suitable for general-purpose machine shops and fabrication units that work with a variety of workpiece sizes up to 63mm in diameter.
Who should choose the 100x80x80mm (AA-1778) V-block?
This larger 100x80x80mm model is best for heavy-duty applications and workshops that machine larger and heavier cylindrical stock, accommodating diameters up to 80mm.
What is the main difference between the AA-1771, AA-1777, and AA-1778 models?
The primary difference is their physical size (Length x Width x Height) and their corresponding workpiece capacity. The AA-1771 is the smallest, for parts up to 40mm, while the AA-1778 is the largest, for parts up to 80mm.
How does the clamping range differ across the AA-177 series V-blocks?
The clamping range is directly related to the size of the V-block. The smallest model (AA-1771) has a range of 5-40mm, the mid-size (AA-1777) has a range of 7-63mm, and the largest (AA-1778) has a range of 7-80mm.
Which Crystal AA-177 V-block offers the best value for a small workshop?
For a small workshop or a startup, the 80x63x63mm (AA-1777) model often provides the best balance of capacity, versatility, and price, allowing you to handle a wide range of common jobs without the expense of the largest size.
