本机机座、横梁均采用框架结构设计，整体刚性好、变形小。

●本机机座固定不动，斜齿轮、齿条传动横梁移动，移动速度可变频调整；切削过程平稳高效，切削表面平整光滑。

●本机为X轴数显，Y1轴、Y2轴、Z轴三轴数控，定位精度高、加工范围大。

●本机分别设有边压料和端压料装置，且均采用液压压紧，压料力可调，压紧可靠。

●液压系统增设蓄能器补偿，电机间隙工作，可节约能源、控制油温。

●本机具有自刨功能，长时间使用后如台面不平整或有瑕疵，可使用自刨功能，使机器焕然一新。

 PGNK (flagship version) Series-CNC Slotting Machine (Self-digging type)

 ●The base and the beam of the machine are frame structure. The entire rigidity is quite good and there is small degree of deformation.

●The base is fixed. The bevel wheel and the spline drive for the beam to move. The speed of moving can be adjusted with altering frequency. The process of cutting is stable and efficient and the surface cut is even and smooth.

●The X axis is for digital display. The Y1, Y2 and Z axes are for digital control with high accuracy of location and large range of processing.

●There are side pressing and end pressing devices on the machine, both of which use hydraulic pressure to tighten. The force of tightening is adjustable and reliable.

●The hydraulic system has one more energy storage compensation function. The dynamo works at interval so the energy is saved and the oil temperature is controlled.

●The machine can self-dig. After long time of operation, if the surface of the machine is uneven or has flaws, the self-digging function can be utilized and the machine will start as a new one.
