Performance characteristics

• Equipped with PLC computer control and easy-to-use color operation screen. Adopting imported PLC processor and displaying touch screen.
• The display screen can show the torque magnitude at three different positions, top, middle, and bottom, of each hole, thereby determining the consistency of the aperture.
• Capable of processing large parts up to 680 kg (1500 lbs).
• The vertical stroke mechanism ensures higher geometric accuracy than other similar equipment, especially in the processing of irregular workpieces.
• The new 2.2 Kw (3hp) servo drive stroke system can improve flexibility and machining accuracy.The stroke servo control ensures consistent internal mesh pattern, precise control of mesh angle, and the ability to achieve short stroke and short pause operations at any position of the hole. The end of the hole can also achieve high-precision honing.
• PLCComputer controlled bottom short honing can achieve high-precision honing of blind holes.
• The workbench is extremely simple, and regardless of the shape of the workpiece, clamping is very convenient and reliable. When changing different workpieces, the tooling cost is extremely cheap.
• Specially madeHeng grinding headWide processing range, various honing strips made with imported abrasives have excellent performance, greatly reducingHoning toolsThe cost.
• Processing accuracy example: Processing ceramic/cast iron cylinder liners with a diameter of ф 100 × hole length of 200, with a margin between 0.15-0.20, rough and fine honing, using diamond honing bars of different thicknesses, with a processing time of 5-8 minutes. After processing, the cylindricity can reach within 0.003, and the roughness can reach within Ra0.2.

Processing occasions:

The MVR220 machine tool is designed for processing large parts with low to medium output, including various automotive engine cylinder block prototype workshops, automotive engine refurbishment and maintenance, various automotive cylinder block repair and maintenance industries, large diesel engine connecting rod processing, large compressor cylinder block processing, compressor cylinder block for train air conditioning, oilfield components, and porous natural gas/Diesel engine cylinder block, various cylinder liners, brake drums, large hydraulic components, and other similar applications. This machine tool is the first large-scale honing system with outstanding competitiveness in the domestic market, priced at only one-third of the same type imported, and some functions are only available at an expensive price5-10It is only available on imported machine tools that are more than double the size.
