 WHN11-CNC - horizontal boring mill – T type
Features:
• contouring horizontal boring machine WHN11-CNC
• cross-shaped beds
• 4 linear axes, rotary table
• sliding workspindle
• machine designed for universal application in engineering production
• suitable for roughing as well as for finishing
• optionally can be fitted by tool cooling kit (CHZ), oil-mist cooling or swarf conveyor
• also can be fitted by non-sliding workspindle up to 5000 rpm or by motorspindle as specified by client
Controlling of the machine:
• all functions of the machine, except tool clamping and unclamping, are controlled via the control panel, which consists of a keyboard, a switch panel and a LCD monitor
• the tool clamping and unclamping is controlled by switches on the headstock
• the control panel is completed with a portable control panel (handwheel), which duplicates some basic functions of the control of the machine
• the control panel is rotary situated on operator platform placed in front of the headstock
• the control system allows manual, semiautomatic and fully automatic modes
• the standard communication interface allows connection with ethernet for easy administration and distribution of technological programs as well as diagnostic or service works of the control system
Low-end version:
Control system:
• HEIDENHAIN iTNC 530 + handwheel
Powered Axes:
• X – travel of rotary table slide on transversal bed
• Z – travel of column slide on longitudinal bed
• Y – vertical headstock travel on column
• B – table rotation
• S – rotation of the sliding workspindle
Manually driven axes:
• W - spindle travel driven by handwheel
Machine capabilities:
• X, Y, Z axes powered in interpolation
• B axis powered only positionally
• linear interpolation of three axes
• circular interpolation of two of three axes powered in interpolation
• spiral interpolation
• spacial interpolation - spline in space
Kinematics of the X, Y, Z axes:
• brushless servomotor with servo-drive
• clearance-free gearing of the timing belt
• ball screw
Kinematics of the W axis:
• handwheel on headstock
• gear set
• trapeziodal screw
Kinematics of the B axis:
• brushless servomotor with servo-drive
• planetary gearbox with minimum clearance
• gear set + gear ring
Group guidance:
• guideways on all linear axes are reinforced with hardened steel plates
• counterways casted by plastic or lined with TURCITE (up client request)
• counterways of headstock are lined with TURCITE including keys standardly
• guideways of the rotary table are casted by plastic
Lubrication:
• central, axial lubrication
• frequency of lubrication cycles correlates to travelled track of a particular group
Clamping:
• X, Y, Z, B, W axes – hydraulically
Headstock:
• sliding workspindle
• spindle driven by four mechanical lines – gears
• hydraulic shifting of each line
• headstock balancing - ropes and counterweight led in column
• setup of tool cooling by jets on headstock front side
Hydraulic power pack:
• HYTOS hydraulic and lubrication set
• lubrication of all groups
• clamping X, Y, Z, B, W
• clamping of the tool
Admeasurement of position:
• HEIDENHAIN digital optical admeasuring
• X, Y, Z axes – LS 187 rules
• W axis – LS 388 rule
• B axis – ROD 780
• S axis – ROD 486
Energy distribution:
• IGUS chain energy carriers
Coverage of machine:
• complete coverage of guideways of X, Z axes
• partial coverage of Y axis
CE:
• comprehensive safety elements according to the applicable legislation and technical standards
• new covered operator platform
• stairs to platform
• working area of the machine is fenced off
