Grinding Machine
The internal grinding machine MX-2018 series is designed for the automotive fuel injection industry and is used for the center hole, internal end face, external circle and end face grinding processing of the valve parts of high pressure common rail hydraulic parts. The machine adopts a steel-inlaid artificial marble bed with good vibration absorption and dynamic stability. The Siemens 840 DSI servo control system and linear motor drive technology with high-precision scales ensure fast movement and precise control. Three grinding heads are arranged on the grinding frame of the machine, which are clamped once and chipped in separate processes. Imported high-precision pneumatic fixtures and automatic intelligent robot loading and unloading methods are adopted to meet the demand of intelligent mass production.
- Grinding diameter: 3-20mm
- Max. grinding depth: 20mm
- Max. clamping diameter: 30mm
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.
