Customer Care, Tooling & Troubleshooting Guide
Providing immediate technical field support, retrofitting services, custom tooling, and a complete engineering troubleshooter.
Our Commitment to Spares, Upgrades, & Field Response
Our relationship with our customers does not end at machine delivery. We understand that in a high-volume production line, machine downtime directly results in financial losses. That is why Arihant has structured a specialized after-sales engineering response cell.
- 24-Hour Field Response: In case of critical failures, our service technicians are dispatched within 24 hours (for industrial belts in Maharashtra, Gujarat, and surrounding states).
- Spare Parts Buffer: We maintain a massive in-stock inventory of Japanese spindle bearings, hydraulic valves, seals, and PLC modules for next-day delivery.
- Retrofitting & Rebuilding: Have an old honing machine of any brand? Our engineers can retrofit it with modern CNC controls, servo stroke units, and state-of-the-art expansion tooling.
Honing Tooling & Stone Selection Criteria
Choosing the correct abrasive grain, bonding matrix, and grit size determines your stock removal rate and target surface finish.
Diamond Abrasives
Extremely hard and highly wear-resistant. Ideal for honing Cast Iron, carbide sleeves, glass-ceramic materials, and hard thermal sprays. Provides excellent diametrical consistency over thousands of cycles.
- High stock removal on cast iron
- Long lifespan (5000+ parts)
- Excellent dimensional repeat
CBN Superabrasives
Cubic Boron Nitride (CBN) possesses high thermal conductivity and does not react with iron alloys at high temperatures. Best matched with hardened steel parts (HRC 55-65), tool steels, and shock absorbers.
- Ideal for high-heat alloy steel
- Rapid cycle times on tool dies
- Eliminates tool wear variables
Conventional Abrasives
Silicon Carbide (SiC) and Aluminum Oxide (Al₂O₃) are highly friable. The grain fractures continuously under load to reveal fresh sharp cutting edges. Best for soft steel, brass, bronze, and aluminum cylinders.
- Clean graphite exposure in iron
- Cost-effective for low volume
- Excellent scratch-free mirror prep

Encountering geometry errors or surface marks? Click on the common defects below to view technical causes and direct corrective actions.
Primary Causes:
1. Excessive hydraulic clamping pressure in fixture chucks, warping the thin-walled workpiece prior to honing.
2. Spindle rotation speed is too slow relative to stroking speed.
3. Rigid fixturing without standard self-aligning gimbal joint adapters.
Engineering Remedies:
1. Implement floating fixtures or reduce clamp holding pressures. Use custom nylon jaw-pads.
2. Increase rotation RPM while slightly lowering the stroking frequency.
3. Dress honing stones to verify flat, complete contact along the entire expansion path.
Primary Causes:
1. Stroke overtravel limits are set incorrectly, causing the stones to under-stroke at one end of the cylinder.
2. Uneven stone wear along the honing mandrel length.
3. Misalignment between the machine spindle axis and the fixture throat.
Engineering Remedies:
1. Adjust stroke control parameters: the stone should overtravel out of the bore ends by 1/3 of the stone length.
2. Configure a short-stroke dwell at the tight end of the cylinder.
3. Turn or flip the abrasive stones in the mandrel slots to equalize wear.
Primary Causes:
1. Metal chip loading (spalling) in the honing stone, where torn material flakes embed back into the bond matrix.
2. Spent chips recirculating in the coolant due to clogged filtration elements.
3. Abrasive grit is too coarse for the targeted alloy.
Engineering Remedies:
1. Use premium sulfurized honing oils or extreme pressure (EP) additives to lubricate and flush cutting paths.
2. Inspect paper roll filters and clean the magnetic drum separators to ensure absolute particle removal.
3. Switch to a softer stone bonding matrix or implement final polish dwell strokes with finer mesh stones (e.g. 600+ grit).
Primary Causes:
1. The stroke overtravel is set far too high, leaving too much stone length hanging outside the bore ends.
2. Pressure expansion continues outside the cylinder confines.
Engineering Remedies:
1. Reduce the stroke overtravel setting (maintain a maximum of 1/4 to 1/3 stone length protrusion).
2. Configure slow servo expansion decay near stroke ends if using CNC mechanical expansion platforms.
