Honing Plate G Series High Performance Special Edition Model
G25-MR2 G Series Special Edition Model
Super precision! Stability! The versatile G series is optimal for mass production of various types at a reasonable cost.
The vertical high-speed honing machine G series is a versatile series optimal for mass production at a reasonable cost. The heart of the honing machine employs an automatic mechanical expansion method for the grinding wheel. It performs precise micro-cutting synchronized with the stroke, enabling ultra-precision machining that improves surface roughness and achieves shape accuracy correction and stable machining diameter in high-precision processing zones even in mass production processes. 6 ADVANTAGES ■ Productivity increase of 10-25% (compared to our company) ■ Stable high precision (cylindricity, machining 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 machining. We have received high evaluations as a leading Japanese manufacturer from customers in the automotive industry, motorcycles, construction machinery, oil and air pressure, 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 (G25 model) and from φ4 to φ100 with a processing length of 130mm (G50 model). Additionally, it features a rotary table to enhance productivity. This is a semi-automatic honing machine designed to reduce production costs, including cycle time reduction. The photo shows the G25-MR2. 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.
