Choose the abrasive for the next operation, not just the lowest disc price. A steel fabrication shop needs cutting discs for separating stock, grinding wheels for weld and edge work, and finishing abrasives for the required surface. Matching these stages can reduce avoidable rework and make consumable trials easier to evaluate.
This guide explains how FUJI Super Raicho cutting discs and Eco Flex grinding wheels fit into everyday metal fabrication, alongside economical Super F2 wheels and flap discs. It focuses on practical selection for sheet, tube, bar, welded brackets and stainless components. The workflows below are application examples, not measured results from a named customer installation.
In this guide: task selection · cutting discs · grinding and finishing · workshop workflows · cost and trials · FAQ
Start with the metal grade, stock thickness and shape, grinder specifications and required finished condition. Ordinary steel brackets and thin stainless panels may pass through similar operations, but they do not necessarily need the same abrasive.
| Operation | FUJI option to evaluate | Selection priority |
|---|---|---|
| Cut sheet, tube or bar to length | Super Raicho thin cutting discs | Material suitability, kerf, stock support and tool compatibility |
| Daily steel weld cleanup and deburring | Super F2 aluminum oxide grinding wheels | Economical removal with control of the remaining weld and edge |
| Controlled grinding on suitable stainless or contoured work | Eco Flex flexible grinding wheels | Contact area, grinding pressure, heat and surface acceptance |
| Blend grinding marks and refine the finish | FUJI ORE flap discs | Grit progression, scratch pattern and specified finish |
A cutting disc is not a deburring wheel. Change to an abrasive approved for grinding before applying side pressure to an edge or weld. Disc shape alone does not establish that both operations are permitted.
The Super Raicho series includes 105mm discs in thin formats such as 0.8mm and 1.6mm. The thinner format offers a narrower nominal kerf, which can help limit material removal during cutting. Actual cutting time, heat and burr formation depend on the workpiece, disc specification and technique; thickness alone does not guarantee a faster or burr-free cut.
Super Raicho cutting discs: select the exact diameter, thickness, bore and material specification for the grinder and workpiece.
If your purchasing specification says 100mm metal cutting disc, do not assume a 105mm disc is interchangeable simply because both are marketed in the 4-inch category. Check the grinder's permitted diameter and guard, spindle and bore requirements, and the disc's marked maximum RPM. Ask FUJI to confirm the matching size before ordering from the cut-off wheel range.
This existing FUJI video demonstrates Super Tsurugi, a separate cutting-disc series. It is not a Super Raicho comparative test and does not establish a guaranteed cutting speed or absence of kickback.
For that alternative, see Super Tsurugi cutting discs. Select between series using the same workpiece and acceptance criteria rather than transferring results from one disc to another.
After cutting, inspect the edge for burrs and the dimensions needed for fit-up. After welding, remove only the material permitted by the drawing or procedure. Grinding a weld flush for appearance is not appropriate when it reduces the required weld size.
An economical aluminum oxide wheel for routine weld cleanup, edge deburring and local steel grinding. Select diameter and specification to match access and the removal task.
A flexible grinding-wheel option to assess where rigid-wheel contact is difficult to control. Suitability depends on the particular grade, material and surface requirement.
Use an appropriate finishing abrasive to refine grinding marks. The required appearance or roughness determines the sequence; one grit does not guarantee every specified finish.
For suitable stainless fabrication tasks, evaluate Eco Flex with controlled contact and steady movement. A flexible wheel can help the operator manage contact on a contour, but it does not remove the need to control pressure and heat. Trial the process on representative material before grinding a finished or thin-walled part.
Keep carbon-steel abrasives separate from stainless work to reduce cross-contamination. Stop and reassess if discoloration, excessive heat or unwanted thinning develops. Do not treat a visually clean surface as proof that every corrosion-resistance or hygienic-finish requirement has been met. The stainless steel grinding and finishing guide covers this workflow in more detail.
Comfort is also a process issue: wheel condition, tool maintenance, grip, work position and exposure time matter. See the FUJI vibration-risk guidance. A flexible wheel alone is not a guarantee against vibration-related injury.
Accept the part on: dimensions, fit-up, retained weld profile, edge condition and finish—not cutting time alone.
Accept the part on: dimensional stability, surface condition and the customer's finish requirements. These steps illustrate a selection process; they are not a report of a quantified customer saving.
A useful shop trial compares the cost per accepted part. A low disc price may be offset by replacement time or rework; a premium disc is worthwhile only when the actual process supports the additional cost.
| Record | Why it matters |
|---|---|
| Material, section and required finish | Keeps unlike jobs out of the comparison |
| Disc dimensions, grade, tool and rated speed | Identifies the tested setup and its compatibility |
| Cutting or grinding time over repeated parts | Shows repeatable process time rather than one fast attempt |
| Accepted parts per disc and changeover time | Captures usable wheel life and interruptions |
| Burr removal, finishing time and rejects | Includes the downstream effect of the abrasive choice |
Practical calculation: divide the total abrasive cost, relevant labor cost and rework cost by the number of accepted parts in the trial. Keep material and acceptance conditions consistent and record operator feedback separately from measured results.
Inspect wheel labels and visible condition before use. Match wheel and machine speed ratings, mounting components and guards. Follow manufacturer instructions for storage, installation and operation, together with workplace protection and spark/dust controls.
The best fit depends on stock size, material, grinder and the required cut. Compare suitable FUJI cutting discs on repeated representative jobs, including burr removal and accepted parts per disc. There is no single thickness that is best for every operation.
No, unless the specific wheel is explicitly approved for that operation. A cutting-only wheel must not be used for side grinding. Switch to a suitable grinding wheel or finishing abrasive.
No. Its narrow kerf can be useful, but results depend on stock, support, cutting technique and tool condition. Inspect each cut and allow for deburring where needed.
Send the metal grade, thickness or section, grinder model, permitted disc diameter and bore, rated speed, daily workload and required finish. Include the current disc specification and the main issue you want to improve.
Tell us what you cut, what you grind and what happens after each operation. FUJI can help identify suitable discs for evaluation against your current process.
