A few days ago, the Jiangxi Provincial Economic and Trade Commission announced some exciting news: four new machine tools from Jiangxi Jike—MK1320 CNC precision cylindrical grinding machine, MQ8260H crankshaft grinding machine, M2110C internal grinding machine, and M215A internal grinding machine—have been recognized as key new products. This marks a significant achievement for the company in the field of precision machining equipment.
The MK1320 is the first precision cylindrical grinding machine in the domestic 20 series to feature a Φ400 grinding wheel. It is equipped with a German 810D two-axis CNC system, an independent CNC control box, CRT liquid crystal display, and FANUC-CNC system. The headstock spindle uses frequency conversion control, while the manual pulse generator, separate hydraulic and cooling system, and independent numerical control operation box help fill a gap in the domestic market. The machine incorporates advanced foreign technology and improves operational efficiency, making it ideal for high-precision applications. Its design includes large round holes and shark fin-shaped ribs on the bed, ensuring excellent dynamic and static stiffness over time. The workbench is split into upper and lower sections, allowing for conical surface grinding. The plastic guide rails reduce friction, and the worktable is driven directly by a servo motor via a ball screw, ensuring smooth and reliable movement. With high precision, automation, ease of use, low vibration, and long service life, this machine is widely applicable in finishing mechanical and automotive components.
MQ8260H is a crankshaft grinding machine known for its simple structure, easy operation, and wide adaptability. It is suitable for grinding crankshaft journals and main bearings, and can also be used for general external cylindrical grinding. It can handle workpieces up to 1600 mm in length and with a maximum crank radius of 110 mm. The machine combines mechanical, electrical, and hydraulic systems, primarily operated manually. It represents advanced technology with promising market potential.
M2110C is a chuck-type internal grinding machine designed for small-batch or single-piece production. It can grind internal holes ranging from 6 to 100 mm, with a maximum grinding depth of 9 mm at minimum diameter and 150 mm at maximum diameter. It can also process conical inner holes (through or non-through) and can grind tapers up to 40° after rotating the headstock. This model has broad market appeal.
M215A is another internal grinding machine suited for small-batch production. It can process cylindrical holes between 3 and 50 mm in diameter, with a maximum grinding depth of 80 mm. It can also grind tapers with angles up to 60° after rotating the headstock. Normally, it comes with an electric grinding wheel spindle running at 60,000 rpm, but options are available for 24,000 rpm and 90,000 rpm models based on user requirements.
According to recent reports, these four new products are expected to pass their official product appraisal before the end of the year, signaling a major milestone for Jiangxi Jike in the competitive manufacturing sector.
