HMC-c Horizontal Machining Center

HMC-c series horizontal machining center adopts same structure with HMC-e, but increases the spindle speed up to 10000r/m and each axis travel speed to 40m/min. It is more suitable for applications in the industries of automobile, diesel engine, and home electric appliances, etc., for higher needs of production efficiency.

The direct drive spindle structure features low noise, small vibration and optimum finishing.
Linear encoder is standard accessory. The closed loop control makes horizontal machining center obtain high position accuracy.

The good chip removing system has structure of 2 helix chip conveyors on the 2 side of machining area, chain type chip conveyor in the middle and spraying system on the top of the protection cover washing away chips, which reduces thermal deformation and then improves the accuracy stability of the machine.

The tool magazine adopts cam indexing mechanism which has high indexing accuracy and fast tool changing speed.
The main components of our machining center are through finite element analysis and optimization.
