ZK21-A series product introduction.

And about ZK21_C series machine tool is single coordinate cnc deep hole drilling machin, the depth of drilling is 1500mm,it include ZK2102C,ZK2103C,ZK2104C,ZK2102C×2 four kinds type.
Optional machining method:
A,standard configuration:
Workpiece rotate, cutting tool rotate and feed with gundrilling method.
B,optional method, the workpiece fixed, the cutting toolrotating and feed with gun drilling method.
Optional CNC controller system:
A,Beijing KND CNC controller system;
B,Japan FANUC 0i Mate TD CNC controller system.
This series of machine is used for processing automobiles, motorcycles, oil pump, nozzle, engineering machinery, mining machinery, military industry and other industries, small and medium-sized deep hole axial workpiece of special equipment. Through a continuous drilling, it can achieve high accuracy and surface roughness instead of general drilling, expanding, the hinge .
we also design ZK2102A x 2,ZK2102A×4 ,ZK2102A×8 high efficiency form machine tool in order to adapt to the requirement of automobile industry and other industries,it can drill two,four workpieces at the same time, so the above model is especially suitable for large parts of the machine.
The machine tool equip the headstock, so the workpiece rotate and cutting tool rotate and feed at the same time,  and the accuracy is very high.

The basic structure

BED: the structure of the bed adopt three sides closed and a reasonable layout reinforcement rib, so it has the good rigidity, the headstock or hydraulic tailstock or special fixture is installated in T slot worktable and drill pipe box carriage feed on sliding table. It also has a wide and deep back oil groove around the bed, ensure the coolant liquid flow smoothly back to oil tank.

headstock: there is a fixed speed.Headstock can move along axial movement according to the length of the workpiece, the rotary workpiece requires less than or equal to 100 mm in diameter. (optional part)

Drill pipe box: it adopts frequency conversion motor or spindle motor drive drill pipe rotation with stepless speed; Spindle bearings uses high precision angular contact ball bearings. Special mechanical seal device provide stable pressure and flow of cooling fluid for deep hole processing, so as to ensure the normal cutting; The drill pipe box feed carriage paste ptfe guide soft belt,which ensure the machine tool has a longer service life. 

The cooling system: There are frequency conversion motor for high pressure oil pump and gear pump and other hydraulic components on the oil tank, and the machine adopts non-woven paper filter, magnet, multistage net type filtering, and forced cooling device, at the same time ,with automatic chip removal machine. 

Centralized lubrication system: front and back bearing of headstock and drill pipe box and slide guide rail uses automatic timing quantitative lubrication, if oil level is lower than standard value,it will have automatic alarm function. 

electrical system: it adopt numerical control system, which can set up automatic programming processing cycle, and also can be manual, inching, opening and closing adjustment, etc. Machine tool operation button stand adopts hanging type, it make the operator observe and operate easyly and directly.

guide frame: guide frame is used for drill head orientation and drill pipe support. In the process of drilling, cutting fluid by the oil pump through drill pipe inner hole to the cutting zone, then it flow to V groove of drill pipe and cavity of the guide frame and bed body, and flow into the automatic chip removal machine, in final,it will be sent to the storage crumbs.

The accuracy of drilling hole
Accuracy of drilling hole:IT7-IT10(good condition IT7-IT8;general IT9-IT10);
Roughness:Ra 0.4-3.2μm
Deviate of center axis:
A:0.25mm/500mm(workpiece roate,length :diameter 100:1,uniform material,suitable feed speed)
B:0.5mm/1000mm(workpiece roate,length :diameter 100:1,uniform material,suitable feed speed)
C:0.5mm/500mm(workpiece not rotate,length :diameter 100:1,uniform material,suitable feed speed)
D:1mm/1000mm(workpiece not rotate, length :diameter 100:1,uniform material,suitable feed speed)
 Our ZK21-C series standard configuration is workpiece rotate and cutting tool rotate and feed at the same time.

Cutting tool life
Continuous cutting length 12-20m(not include special material)
And cutting tool can use 50times by The cutting tool resharpening , so the total length of cuttting can be more than 600m, good condition is more longer.
