The machine is specially used for cylinder jobs,the machine has good rigidity,good accuracy. In front of the machine,installed one set double chuck clamping device and two sets ring type center rest,which is suitable for drilling drill collar.
The spindle rotate range is widely,infeeding system is driven by AC servo motor,which can be used for variously deep hole drilling process. Oil pressure fasten device and job tight adopts hydraulic device,instrument display,safe and reliable.
Machine basic structure and components:
1）Machine bed：Guide rail adopts double flat rail design,machine bed width 650mm. Material is super casting iron HT300. artificial aging treatment;guide rail surface middle frequency quenched,quenched depth 2-3mm,quenched hardeness HRC45-50. High precision and good abrasion resistance.
Machine Bed guide rail middle install”T” ball screw driven support carrier,used for infeeding and carrier rapid movement.
2）Headstock and chuck:headstock has three shifts,12 grades,speed range: 42-670r/min,headstock box iron adopts artificial timing,all the gears adopts super medium carbon steel or low carbon alloy steel,quench hardenness is more or less HRC48, gear grinding process,improve the working accuracy and wear resistance. In front of the headstock,there is a button station,which can realize the spindle forward and stop control. The headstock is a non moving structure ,and the main motor is fixed on the bed body.
The lantern chuck is mainly fixed in front of the spindle,install 320mm three-jaw chuck on the chuck body.
3）Drill box ：the drill box is two shifts, six stage speed regulation,speed range: 82—490r/min.Drill box adopts super casting iron,HT250. Artificial aging. All the gears adopts super medium carbon steel or low carbon steel,quench hardness HRC48 more or less. gear grinding process,improve the working accuracy and wear resistance.
Drill box has rotating and fixed two designs,when no need drill bar rotate,can lock the drill box.
4）Oil pressure head ：Function of the oil pressure head
a.Input coolant liqud to the job and seal. b.Can install guide bush,which can guide the drill tool. c.Support drill bar
In front of the oil pressure head,we install the machine coolant and hydraulic display instrument,when the machine is processing,the operator can judge the machine working status.
5）Double chuck clamping device ：
The double chuck mounted in front of the oil pressure head,which can be better centering and support the job. This design is suitable for drill collar.
6）Cutting liquid supply system: Mainly consists of oil box,oil transport tube,chips storage bin and oil return groove. Four groups pump and four gear pump,according to hole diameter,customers can get flow of 100 L/min ,200 L/min,300 L/min ,400 L/min three the buttons. The oil box is on the ground,not under the ground,no need dig the pit.
7）Infeeding system: Dragged by the servo motor,after transmission through the gear box and through the T type screw driven,which can realize the carrier forward and backward. Infeeding is stepless and speed adjustment range is 5 ~ 450mm/min.
8）Drilling,boring bar rest ：Support the drilling bar,control the drilling bar move direction. Has the function of tight nylon bush and absorb drill bar vibration.
9)Electrical control system: ：Mainly electrical components adopts Schneider brand,much more steady and reliable.
10）Chips discharge bin: collect iron chips and cutting liquid,avoid cutting oil splash.
When drilling,adopts BTA,cutting oil will enter from oil pressure head, through drill tool outer and processed(drilled) surface ring into cutting area,bring the chips into the back(drill box direction),go into the chips discharge tube,and flow into the chips bin.
11)Ring type center rest:The machine has two sets ring type center rest. Mainly can adjust job center and support job.
The machine infeed carrier is mounted intermittent lubrication system, and it has automatic alarm function with low amount of oil, saving oil on the basis of the carriage and the feed screw can get sufficient lubrication in the greatest degree.Headstock and drill box each have their own set of lubricating device. Oil pressure head and drill bar support rest adopts manual lubrication.
13)Machine tools：customer provide or separately ordered
14)Cutting oil and lubricate oil: customer provided
Machine processing accuracy:
Drilling：Hole accuracy IT9-11
Surface roughness ：Ra6.3-- Ra 12.5。
Hole processing line straightness ： Less than 0.15/1000mm。
Hole exit deviation(center line) ： Less than 2mm/10000mm。
