More questions buyers ask
What are Elongated V-Blocks used for?
Crystal Elongated V-Blocks are precision tools used in workshops and tool rooms for accurate marking, checking, drilling, and milling of round or square workpieces. Their elongated shape provides a stable and accurate base for various machining and inspection tasks.
What is the difference between Grade A and Grade B V-Blocks?
Grade A V-Blocks are made from high-quality, hardened tool steel for maximum precision and are intended for tool room and quality control applications. Grade B V-Blocks are made from extra-hard and dense cast iron, offering excellent durability for general workshop use.
Are Crystal V-Blocks magnetic?
This specific range of Elongated V-Blocks is non-magnetic. Crystal also manufactures a separate range of Magnetic V-Blocks for applications requiring magnetic clamping.
What is the accuracy of Crystal Precision V-Blocks?
All Crystal V-Blocks are precision ground on all sides to be parallel and square, ensuring high accuracy for all tool room and workshop operations. The specific tolerance depends on the grade.
Can I get a GST invoice for my purchase?
Yes, we provide a GST invoice for all purchases. You can claim input tax credit on your order.
Do you offer pan-India shipping?
Yes, we deliver Crystal V-Blocks to all locations across India, including major industrial cities and remote areas.
Who should choose the Crystal Grade A 100x40x32mm V-Block?
This variant is ideal for precision engineers, tool rooms, and quality control departments that require the highest level of accuracy for small to medium-sized components. Its tool steel construction ensures long-term precision.
Who should choose the Crystal Grade B 100x40x32mm V-Block?
The Grade B 100x40x32mm V-Block is perfect for general machine shops, fabrication units, and training institutes. It offers a fantastic balance of durability, accuracy, and cost-effectiveness for a wide range of tasks.
Who should choose the Crystal Grade A 150x50x40mm V-Block?
This larger Grade A V-Block is designed for workshops and manufacturing facilities that handle bigger and heavier workpieces. It provides the same high precision as its smaller counterparts for large-scale machining and inspection.
What is the main difference between the 100mm and 150mm Crystal V-Blocks?
The primary difference is the size and load-bearing capacity. The 150mm V-Block is designed to securely hold larger and heavier cylindrical or square jobs, while the 100mm version is more suited for smaller, standard-sized components.
Is Grade A significantly more accurate than Grade B for general workshop use?
While Grade A offers higher precision for specialized tasks, Grade B provides excellent accuracy that is more than sufficient for most general milling, drilling, and marking operations. For non-critical applications, Grade B offers better value.
Which Crystal V-Block offers the best value for a tool room?
For a tool room, investing in a Grade A V-Block is highly recommended. The higher initial cost is justified by its superior accuracy and longevity, which is critical for inspection and precision machining tasks.
