Features

The CNC Internal Grinding Machine MK2150 series is characterized by its highly efficient automated grinding capability and sophisticated control system. It is capable of automatically completing the grinding of bore and endface after the workpiece is clamped in one setup, ensuring the continuity and consistency of the machining process. The key moving parts of the machine, including the Z-axis of the table and the X-axis of the grinding wheel, are controlled by the Siemens AC servo system through high-precision ball screws, which ensures the precise movement of each axis.

• The grinding wheel holder and table of the machine are respectively equipped with linear rolling guideway and flat V-type molded guideway, which provide stable support and smooth movement. The high-precision roller bearings used in the headstock and the AC frequency conversion speed control system provide the machine with smooth speed changes.
• The workpiece clamping system includes a hydraulic membrane chuck, a tilting wedge type sliding jaw chuck and an end face chuck. These diverse clamping methods accommodate workpieces of different shapes and sizes, enhancing the versatility and flexibility of the machine.
• For dimensional control, the machine adopts fixed-range grinding and measurement in gauge machining to improve machining accuracy. The magnetic plus paper precision filter of the cooling system ensures the cleanliness of the coolant and prolongs the service life of the machine.
• The grinding wheel spindle is driven by a mechanical grinding head through a high-precision belt drive, providing stable grinding performance. The machine’s fully enclosed hood and mist absorbing device not only enhance the safety of operation, but also meet the safety and protection standards of modern machine tools.
• In addition, the machine’s guideways and ball screws are lubricated by a centralized automatic lubrication station, which reduces maintenance workload and improves the machine’s operating efficiency. The integrated design of the electrical box and the machine simplifies the installation process and saves space.

Applications

• Fully automatic CNC internal grinding machine MK2150 series is mainly used for grinding internal bore, internal concave endface, external endface, multi-stage internal bore, multi-stage endface, and is a multi-purpose production machine tool. The entire grinding cycle of the machine is completed automatically, including automatic feeding, automatic dressing of the grinding wheel, automatic compensation, automatic size control, and the operator only needs to assemble and disassemble the workpiece. The machine is suitable for both single-piece, small-lot and large-lot production.
