Product Introduction

G1420, G1432B, G1450, G1463 universal cylindrical grinders use electric and hydraulic interlocking mechanisms with various moving parts to ensure safe and reliable operation. It is suitable for grinding IT6-IT5 precision inner and outer cylindrical or conical rotating workpieces. It is suitable for single-piece small batch and batch production workshops.

Product Features :

• The horizontal feed of wheelhead is driven by hydraulic pressure to realize micro automatic periodic feed and fast advance and regress.Also can do manually rough fine feeding.
• G1350, G1450, G1363 series table and wheelhead guide rail adopt static guide rail, low speed motion is stable.
• G1350, G1450,G1363 series wheelhead with high rigid spindle, high rotary precision, good rigidity. The workhead adopts frequency converter to realize stepless speed regulation.
• Universal workhead can be adjusted at any Angle within 90 degrees counterclockwise to adapt to chuck grinding internal and external conical workpiece.

In terms of diameters, the grindable cylindrical diameters range from 8 mm to 320 mm, which can meet the grinding needs of workpieces from finer to larger diameters. For internal bores, the grindable diameters range from 30 mm to 100 mm. In terms of length, the maximum length of grindable cylinders varies according to the model, with common specifications of 1000 mm, 1500 mm, 2000 mm, 3000 mm and other specifications, which can be adapted to the processing of workpieces of different lengths. Among them, the maximum length of grindable bore is up to 125 mm. The grinder can also process workpieces with a maximum weight of 150 kg and can handle parts within a certain weight range.

In addition, the grinding wheel holder is angle adjustable in the horizontal plane (±30°), which greatly expands the machining range and makes it possible to grind not only general external cylindrical surfaces and internal bores, but also short conical surfaces and other workpieces with angular requirements. Both shaft parts and cylindrical workpieces with conical features can be processed on this grinder. This wide range of processing makes G1432 cylindrical grinder highly adaptable in the field of machining, and it can be used in the manufacture of parts in a variety of industries, such as the processing of automobile parts, mechanical transmission components, precision instrument parts, etc. It can meet the grinding needs of different customers for different types and sizes of workpieces, and provide a strong guarantee for the production of high-quality precision parts.
