Granite V-shaped frame

Granite V-shaped frame is a precision measuring tool used to support and position cylindrical workpieces,named after its V-shaped groove design.The following is a detailed introduction to granite V-shaped frames:

characteristic

High precision:Made of high-quality granite,after precision machining and grinding,the angle and size accuracy of the V-shaped groove is high,which can accurately locate and support the workpiece,ensuring the accuracy of measurement and processing.

Good stability:Granite has good stability and wear resistance,is not easily deformed,and can maintain accuracy for a long time.At the same time,it also has good seismic resistance and can be used stably in different working environments.

High surface quality:The surface of the granite V-shaped frame is finely ground with low roughness,which can make good contact with the workpiece surface,reduce measurement errors,and is not easy to damage the workpiece surface.

Strong corrosion resistance:Granite material is resistant to acid and alkali corrosion,not easy to rust,does not require special anti-corrosion treatment,has low maintenance costs,and has a long service life.

purpose

Measurement and positioning:In mechanical processing and metrological testing,it is commonly used to locate and measure cylindrical workpieces,such as measuring the diameter,roundness,cylindricity and other parameters of the cylinder,providing accurate benchmarks for measurement.

Workpiece clamping:During the machining process,it can be used as a clamping tool to fix cylindrical workpieces on a V-shaped frame,facilitating machining operations such as turning,grinding,drilling,etc.,to ensure machining accuracy.

Inspection and Calibration:Used to calibrate some measuring instruments and tools related to cylindricity,such as external micrometers,dial indicators,etc.,to ensure the accuracy of these instruments.

accuracy class

The accuracy level of granite V-shaped frames is usually divided into 0 level,00 level,etc.The accuracy of level 00 is higher than level 0,and specific accuracy indicators include the angle deviation,straightness,parallelism,and flatness of the V-shaped groove.For example,the angle deviation of the V-groove of the Class 00 V-frame may be within±5',the straightness and parallelism errors may be between 0.001-0.002mm,and the flatness error may be between 0.002-0.005mm;The precision indicators of the 0-level V-shaped frame are relatively lower.
