Used VIGERT ZC686H Grinding Machine For Sale

ZC686H Grinding Machine often referred to as a universal grinder, is a versatile machine tool used for grinding and shaping cylindrical workpieces. It is widely employed in various industries, including manufacturing, aerospace, automotive, and toolmaking. Here’s a detailed description of a Universal Cylindrical Grinder Machine:

1. Machine Bed and Base: ZC686H Grinding Machine. The machine typically features a heavy and rigid bed or base, often made of cast iron or steel, to provide stability and minimize vibrations during the grinding process.
2. Work head: The work head is the part of the machine that holds the workpiece and rotates it during the grinding operation. It is equipped with a spindle that can be adjusted for various workpiece sizes and lengths. Some models may include a dead center or chuck for workpiece holding.
3. Contropunta: A tailstock is often present at the opposite end of the work head to provide additional support for the workpiece. It can be adjusted for workpiece length and is typically used for longer workpieces.
4. Mola: Universal Cylindrical Grinder Machine. The machine is equipped with one or more grinding wheels that rotate at high speeds. These wheels are responsible for removing material from the external surface of the cylindrical workpiece. Universal grinders often allow for the use of different types and sizes of grinding wheels to accommodate various grinding tasks.
5. Wheel head: ZC686H Grinding Machine. The wheel head holds and controls the grinding wheel’s position and movement. It can be adjusted both axially (in and out) and radially (side to side) to achieve precise grinding results. Some machines feature a swiveling wheelhead for external and internal grinding or for angled grinding operations.
6. Controllo CNC: Many modern Universal Cylindrical Grinder Machines are equipped with computer numerical control (CNC) systems. CNC control allows for precise control of the grinding process, including wheel speed, feed rate, and depth of cut. It also enables the creation of complex profiles and automation of the grinding process.
7. Sistema di raffreddamento: A coolant system is employed to dissipate heat generated during the grinding process and to remove grinding swarf (metal particles). The coolant is delivered to the grinding zone to improve the surface finish and extend the life of the grinding wheel.
8. Dressing Mechanism: ZC686H Grinding Machine. wheels wear over time and may need periodic dressing or truing to maintain their shape and cutting efficiency. The machine may have an automatic or manual dressing mechanism for this purpose.
