Honing Plate G Series High-Performance Cell Type Model
F25G-M4DR G Series Standard Model
Flexible G-series cell-type model for production fluctuations tailored to your needs!
The vertical high-speed honing machine G series cell-type model can enhance the added value of the honing machine with a flexible combination of "cells" that can be increased or decreased. It occupies little space and can respond flexibly to specific purposes. The heart of the honing machine, the grinding wheel expansion method, adopts an automatic mechanical expansion system. It performs precise micro-cutting synchronized with the stroke, enabling ultra-precision processing that improves surface roughness and achieves correction of shape accuracy and stable processing diameter in high-precision machining zones even in mass production processes. 6 ADVANTAGES ■ Productivity increase of 10-25% (compared to our company) ■ Stable high precision (cylindricity, processing diameter, surface roughness) ■ Ease of use ■ Energy saving of 90% (compared to our company) ■ Space saving of 15-30% (compared to our company) ■ Low noise at 70dB Nisshin Seisakusho, as a comprehensive manufacturer of honing machines, selects the machine body, tools, grinding wheels, and jigs comprehensively with unique know-how to achieve ultra-precision processing. We have received high praise as a leading manufacturer in Japan from customers in the automotive industry, motorcycles, construction machinery, oil and pneumatic, home appliances, molds, general-purpose engines, sewing machine industries, and more.

basic information
Covers processing diameters from φ3 to φ40 with a processing length of 80mm (F25G model) and from φ4 to φ100 with a processing length of 130mm (F50G model). Thanks to its cell machine design, it allows for "add-ons" that increase the amount of material removed and shorten processing time, enabling adjustments and repurposing after equipment delivery, making it a honing machine unlike any other. Additionally, this model (optional) can perform match honing based on data obtained after external diameter measurement. It features a synchronized stone expansion function that stabilizes surface roughness according to stroke, and an automatic stone extension function that completes the stone extension process with the push of a button. When combined with measurement management software, it allows for detailed analysis through aggregation of measurement results and graphing capabilities. The photo shows the F25G-M4DR. Due to processing length and conditions, the maximum speed may not be achievable, and the length that can be processed is also limited by the required processing accuracy. This specification may change without notice for product improvement, so please feel free to contact us for detailed functionality.
