High Precision CNC Horizontal Deep Hole Tube Honing MachineDHK-100 DHK-200 DHK-250
Machine Summary:*The series CNC deep hole honing machine is the dedicated machine for honing and polishing of deep hole. Mainly for fine processing of the precision parts, it is an ideal deep hole processing machine with high precision and high efficiency.
*The modified version type of the machine can be designed according to the different demands. *Absorbing the advanced experience home and abroad, this machine can realize accurate control of timing, positioning and quantifying in the process of production. With the development of high- performance abrasive and automated honing machine, the honing application range will get wider and wider.
Performance and Features:*The machine adopts the mode of workpiece fixed, honing head rotating and reciprocating. It has a wide appliation, especially for processing of non-rotary workpiece, such as hydraulic cylinder, air cylinder, square body, the workpiece with rotary shaft and flange plate, etc.
*The workpiece is fixed by V-type supporting and chain locking. The machine can be programmed to realize automatic operation, with setting up to honing time, reciprocation frequency and honing distance. It is suitable for mass production or single maintenance production. The machine selects Taiwan Delta control system with human-machine interface touch screen.
*The surface roughness is up to Ra 0.2µm and roundness is less than 0.03mm, the hole tolerance is up to IT7 or above.
