 WHO11NC-CNC/35 - horizontal boring mill – table type
This document relates only to the machine WHO11NC, it does not cover the machines in the development range WHO11.1 and WHO11.2, which are of very different concept.
Features:
• contouring horizontal boring machine WHO11NC-CNC/35
• fixed column, crosswise travelling table
• 4 linear axes, rotary table
• sliding workspindle
• machine designed for universal application in engineering production
• suitable for roughing as well as precision contouring
• optionally can be fitted by tool magazine with manipulator (ATC), tool cooling kit (CHZ), cooling through spindle axis (CHOV) or oil-mist cooling
• 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 situated on the rotary console 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
• SIEMENS SIN 840D + handwheel
Powered Axes:
• X – travel of rotary table slide on saddle
• Z – travel of saddle on bed
• Y – vertical headstock travel on column
• W – spindle travel
• B – table rotation
• S – rotation of sliding workspindle
Machine capabilities:
• X, Y, Z, W axes powered in interpolation
• B axis powered only positionally
• linear interpolation of four axes
• circular interpolation of two of four axes powered in interpolation
• spiral interpolation
• spacial interpolation - spline in space
Kinematics of the movable X, Y, Z, W groups:
• brushless digital servomotor with servo-drive
• clearance-free gearing of the timing belt
• ball screw - radioaxial bearing at both ends
Kinematics of the B axis:
• brushless digital servomotor with inbuilt gearbox with servo-drive
• gear set + gear ring
Group guidance:
• guideways on all linear axes are reinforced with hardened steel plates
• counterways are lined with TURCITE including keys
• guideways of the rotary table are scrapped
Lubrication:
• central, axial lubrication
• frequency of lubrication cycles correlates to travelled track of a particular group
Clamping:
• X, Y, Z, W, B axes – hydraulically
Headstock:
• sliding workspindle
• spindle driven by four mechanical lines – gears
• hydraulic shifting of each line
• headstock balancing - ropes and counterweight led on side-wall of 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, W, B
• unclamping of the tool
Admeasurement of position:
• HEIDENHAIN digital optical admeasuring
• X, Y, Z axes – LS 187 rules
• W axis - LS 487 rule
• B axis – ROD 280
• 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
• operator housing
• working area of the machine is fenced off

Optionally:
ATC:
• ATC facility is a separate unit and it is not fixed to the machine
• magazine with servodrive for tool beds positioning
• changer driven electrically / pneumatically
CHZ:
• tool cooling set with jets on headstock front side
• separate cooling unit – tank with pump, level gauge, pressure test
• tank volume approx. 150 l
• maximal pressure 4 bars / 32 l/min
• setup for tool cooling always included – distribution pipes, jets
CHOV:
• once production has started is not possible to add into configuration
• separate cooling unit with filter and magnetic swarf separator required
• maximal pressure 40 bars – emulsion - tank volume 1000 l
• maximal pressure 80 bars – oil - tank volume 100 l
• both emulsion and oil may not be used for one particular machine
• other necessary alterations to machine and CE features depend on the required cooling pressure
• for pressure higher than 10 bars the cover of the workpiece must be used, with mechanical-pneumatic opening of door and top
Oil-mist cooling:
• can be added to machine at any time
• easy to assemble
• easy to use
Non-sliding spindle:
• non-sliding spindle up to 5000 rpm
• distance of spindle face from headstock face c. 400 mm
• spinle drive with four hydraulically switched mechanical lines remains principally the same
Motorspindle:
• spindle parameters as specified by client
Machine design can be tailored to suit the needs of the client.
