Product Description
ZK21xxG CNC deep hole drilling machine
This machine is a special purpose CNC deep hole drilling machine with high efficiency, high accuracy and high automatization, by metal chips external removing method (gundrill method), once continued drilling can replace drilling, boring and reaming etc. many machining procedure, and obtain the same machining accuracy and surface roughness. controlled by CNC system, not only has the machine single moving function, but also automatic cycle function. therefor it is suitable for both small and large batch production. This machine can drill through hole, blind hole and step hole, mated with special holders, it can also drill eccentricity hole and slant hole.
Characteristic of the machine
All the bed and boxes of the machine adopt fine casting, so they have good rigidity and stability.
The cutter need not untread during machining.
Controlled by CNC system, the automatization is high.
The movement of the cutter adopt rolling linearity guide way.
The clamp of the workpiece adopt high precision chuck and hydraulic steady rest so as to realize self centering clamp accurately.
The Min. drilling diameter is Φ2mm.
Feed system is diven by AC servo motor and ball screw couples with stepless speed.
The spindle speed of the travel headstock with rotating drilling bar is stepless.
Spindle bearing and surface of guide way are lubricated intermittently.
High pressure coolant system adopt frequency converting motor to drive gear pumps, and adopt immerged oil temperature controller.
Adopt automatic metal chips conveyer.
Adopt whole closed guard cover with convenient view windows and beautifule outline.
With multi-automatic surveillant and controll devices.
Main specification and features
Standard sheme:
KND KND or GSK CNC system, manual pulse control box, vibration damper steady of drilling bar, chain plate type automatic chip conveyer,whole closed guard cover, centred lubrication station, special purpose coolant system, alarm light, tools, work light, levelers, oil temperature controller, hydraulic system, headstock, hydraulic steady rest, high precision chuck etc.
Optional devices:
