Do these V Blocks come with clamps?
Yes, the Series AA-172 V Blocks are supplied with integrated clamping screws designed to securely hold the workpiece without protruding over the sides.
What material are the Crystal V Blocks made of?
They are constructed from hardened ground steel, specifically high-quality tool steel, to deliver consistent accuracy and resist deformation.
Are the top and bottom V grooves parallel?
Yes, the top and bottom V grooves are precision ground to be parallel within ± 3 microns.
What is the squareness accuracy of these V Blocks?
The squareness to the end faces and height variations in a matched pair are controlled within ± 3 microns.
Can these V Blocks be used for CNC setup?
Absolutely. Their high precision and stable clamping make them ideal for both manual and CNC machining setups.
How should I maintain my Crystal V Blocks?
Store them in a dry environment, clean surfaces before and after use, avoid dropping them, and apply a light coat of oil for protection during storage.
Does the clamp protrude over the sides of the V Block?
No, the V Blocks are specifically designed so that the clamps do not protrude over the sides, allowing for versatile positioning.
Are these V Blocks supplied in matched pairs?
Yes, they are typically supplied in matched pairs to ensure perfect alignment and consistent height for supporting long workpieces.
What is the surface finish of the Crystal V Blocks?
They feature a precision ground surface finish that supports reliable measurement tasks and ensures stable workpiece contact.
Who should choose the Crystal AA-1721 V Block (65 x 150 x 75 mm)?
The AA-1721 is ideal for tool rooms and workshops handling small to medium-sized cylindrical components that require precise clamping and inspection.
Who should choose the Crystal AA-1722 V Block (65 x 175 x 100 mm)?
The AA-1722 is best for professionals needing a versatile, mid-sized V Block for general-purpose machining, drilling, and quality control tasks.
Who should choose the Crystal AA-1723 V Block (75 x 200 x 125 mm)?
The AA-1723 is designed for heavy-duty industrial applications, providing maximum stability and support for large, heavy workpieces during complex machining.
What is the difference between the AA-1721 and AA-1723 V Blocks?
The primary difference is size and capacity. The AA-1721 is 150mm long, suitable for smaller parts, while the AA-1723 is 200mm long and wider, designed to support larger and heavier workpieces.
How does the size affect the application of these V Blocks?
Larger V Blocks like the AA-1723 offer a wider V-groove and greater mass, allowing them to securely hold larger diameter cylinders and absorb more vibration during heavy machining compared to smaller models.
Which Crystal V Block is best for large workpieces?
The AA-1723 (75 x 200 x 125 mm) is the best choice in this series for large workpieces due to its increased dimensions and robust support capabilities.
