About ROUGHNESS COMPARATOR

This set consists of 30 comparison specimens, covering six of the most commonly-used machining methods: 6 cylindrically turned, 6 end-milled, 6 horizontally milled, 6 surface-ground, 3 lapped, 3 reamed/drilled..25 LtrA

Corrosion-Resistant Durability

Manufactured from robust stainless steel or aluminum, these comparators resist corrosion and withstand industrial or laboratory use. The precision-machined sample strips maintain their integrity, providing reliable performance for long-term surface roughness assessment.

Wide Range of Surface Finishes

Each set features between 12 to 30 specimens, covering finishes from ground to honed. This diversity allows technicians to assess and match a variety of machining processes, making this tool adaptable to multiple applications in quality control and machining validation.

Portable and User-Friendly

Weighing roughly 200 grams and packaged in a protective case, the comparator is easy to carry and use in the field, workshop, or laboratory. Its mechanical, manual operation means no need for power or extra calibration-just select, compare, and reference instantly.

FAQ's of ROUGHNESS COMPARATOR:

Q: How do I use a roughness comparator for surface assessment?

A: Hold the desired comparator specimen next to the machined workpiece and visually or tactilely compare the surface textures. Match the finish closest to your sample to estimate the Ra value.

Q: What materials are the roughness comparators made of?

A: These comparators are made from corrosion-resistant stainless steel or aluminum, making them suitable for demanding industrial or laboratory environments.

Q: When should I use a roughness comparator?

A: Use a roughness comparator whenever you need a quick, visual reference for verifying or comparing the surface finish of machined parts, such as during manufacturing, inspection, or quality control processes.

Q: Where can the roughness comparator be used effectively?

A: It's designed for indoor laboratory or workshop settings and is suitable for environments with ambient temperatures (10C-40C) and controlled humidity.

Q: What is the process for identifying the correct surface finish using this tool?

A: Select a comparator strip with the desired process (e.g., milled, turned) and Ra value, and compare it directly against your workpiece to quickly determine the finish quality.

Q: What are the benefits of using a physical roughness comparator over a digital gauge?

A: Physical comparators provide immediate, power-free visual assessment, require no calibration or batteries, and are highly portable-making them ideal for field or workshop use in environments where digital instruments might be impractical.

Q: Who can supply or provide support for roughness comparators in India?

A: As distributors, manufacturers, service providers, and suppliers in India carry these roughness comparator sets, you can source them locally for prompt delivery and support.
