Features

• The machine is equipped with a steel and artificial marble bed with good vibration absorption and high dynamic stability.
• The machine has a fixed grinding frame, longitudinal reciprocating oscillation of the workpiece and transverse feeding grinding mode.
• Adopting Siemens 840DsI servo control system, the X-axis of feeding and Z-axis of reciprocating are directly driven by linear motors, equipped with high-precision absolute scales, with fast moving speed and high precision.
• The X-axis and Z-axis movement guideway of the machine tool adopts high-precision hydrostatic guideway imported from INA Company of Germany, which has high accuracy retention, high speed and good vibration resistance.
• Three grinding heads are arranged on the grinding frame of the machine, which are clamped at one time and chipped in separate processes. Among them, two German GMN imported high-speed spindles with center cooling are used for the processing of inner hole and inner end face respectively; the external grinding head is used for the processing of external circle and external end face.
• Diamond disc dressing grinding wheel, small grinding wheel adopts CBN grinding wheel, the whole cemented carbide joint rod, large grinding wheel adopts ceramic grinding wheel.

• Imported high-precision pneumatic fixture, fixture rotary accuracy and high repeat positioning accuracy.
• Automatic intelligent robot loading and unloading mode, to meet the needs of intelligent mass production.

Applications

• External round center hole and end face compound grinding machine MX-2018 series is mainly used for the grinding of internal hole and internal end face, external round and external end face of the valve parts of the hydraulic parts of the common rail for automobile fuel high pressure. It can also be used for the machining of center hole and seat surface and end surface of common rail injector valve body.
