Horizontal Heavy-Duty CNC Cylinder Deep Hole Honing MachineDHK-350 DHK-500 DHK-800
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.
*Adopting the special oil for cooling, the work area is almost not deformed and it is up to the higher precision on size and geometry with an excellent surface finish. Honing is the important processing method of precise inner hole and long hole, which has a high efficiency.
*There is the crossing texture on the surface of oilstone, it is good for protection of lubricant film, and avoiding effectively occurring of embedded sand. So the using life is prolonged.
