Deep Hole Drilling Machine Gun Drilling Machine

                          ZK2102A deep hole drilling machine                     single coordination gun drilling machine       This machine is a special-purpose deephole drilling machine with properties of high efficiency,high accuracy and high automation.It adopts external-chip removing method (gundrill method),through one continues drilling,it can realize the machining accuracy and surface roughness usually by the progress of drilling,expanding and reaming.The machine is controlled by CNC system with function of both single action and automatic recycling so that it can meets the requirements of small batch and large batch machining.The machine can drill through hole,blind hole and step hole.The machine can be widely used in the line of automobile and motorcycle,mould,military and aeronautics.Main Specifications and Featuresspecificationstechnical datarange of drilling dia.3-20mmMax.Drilling depth500mm/1000mmhead stock spindle speed380r/minrange of drilling box spindle speed(infinite)800-7000r/minfeed speed range(Z-axis)(infinite)10-500mm/minpressure range of coolant1-10MPaflow range of coolant6-100L/minrapid speed of feeding carriage3m/mintorque of feeding motor7Nmmotor power of drilling bar box4kWmotor power of headstock1.5kWgeneral motor power20kW(about)overall dimension(LxWxH)4000x4050x2050(500mm) 5050x4050x2050(1000mm)machine weight6t(500mm) 7t(1000mm)Note:Tools and accessories must be ordered specially,coolant should be prepared by the user or bought from the manufacturer.Features1.Adopting FANUC Oi mate-TB system2.driven by A.C servo motor,transmitted by ball screw3.adopting guideway conglutinated plastic,smooth running in low speed,without creeping4.spindle speed of drilling bar box is driven by varyspeed motor,adjustment stepless5.spindle bearing and guideway surface adopting automatic intermittent lubrication6.high-pressure coolant is supplied by varyspeed motor-driving gear pump7.flat chain type automatic chip conveyor8.fully covered safe guard9.muti-monitoring device10.kinds of patentsZK21-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.C,Germany SIEMENS-PRECION 01 CNC 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 val
