By making precise and minute cuts that are synchronized with the spindle stroke, the G series not only improves surface roughness, but also enables ultra-precise machining. It achieves this by correcting the forms of precision zones and ensuring consistent bore diameters, even when dealing with mass-produced parts. ## Product Video ### Pinion Stacked Honing ## Features - ### Shorter processing times High-speed operation leads to reduced processing times. - ### Consistent precision and accuracy High-precision processing is achieved through synchronized stone expansion, leading to consistent precision, accuracy, and surface roughness as stone expansion is also in synchronization with the spindle stroke. - ### Comprehensive customer support NISSIN ProSOL provides ongoing, comprehensive support from initial consultation through to after-sales service. We cover everything from providing test processing and optimal equipment proposals to providing a range of services and tailored solutions for after-sales support. ## Specifications | Model | G25 | G50 | | | | | --- | --- | --- | --- | --- | --- | | Number of honing spindles | 1 | 2 | 1 | 2 | | | Honing range | Diameter | φ3～φ40 | φ4～φ100 | | | | Length | 80mm | 130mm | | | | | Driving method | For spindle rotation | Servo motor | Servo motor | | | | Spindle speed | Operating RPM range | 1～3,000rpm (Timing Belt) | 1～3,000rpm (Timing Belt) | | | | Spindle stroke | Speed | Maximum | 40m/min | 30m/min | | | Stroke | Max. stroke | 200mm | 300mm | | | | Min. setting | 0.01mm | 0.01mm | | | | | Stone expansion | Expansion method | Fixed amount expansion | Fixed amount expansion | | | | Expansion amount | Min. setting | 0.01μm/1 expansion | 0.01μm/1 expansion | | | | Number of honing programs | 30 | 30 | | | | | Machine weight | 1,600kg | 2,800kg | 1,800kg | 3,000kg | | | Machine dimensions | Width | 1,300mm | 1,700mm | 1.300mm | 1,700mm | | Depth | 2,400mm | 2,400mm | 2,400mm | 2,400mm | | | Overall height | 2,150mm | 2,150mm | 2,250mm | 2,250mm | | Maximum speed shown may not be available for some honing lengths and conditions.
