 WFQ80NCA-CNC/50 - horizontal boring mill – T type
This document covers only the WF80NCA and the WFQ80NCA machines, and does not include the previous development range of the WHQ9 and the WFQ80NC. The reconstruction of these machines is not under consideration because of the particularly low level volume of produced pieces and the fundamental difference in the design of the individual assemblies.
Features:
• contouring horizontal boring machine WFQ80NCA-CNC/50
• cross-shaped beds
• 3 linear axes, rotary table with additional supports and non-sliding workspindle
• machine designed for universal application in engineering production
• allows carousel usage of rotary table
• 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), oil-mist cooling, swarf conveyor or motorspindle
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, semi-automatic and fully automatic modes
• in case the machine is fitted with the automatic tool changer (ATC), the extra hand-held ATC control panel is needed. This is used when the magazine is loaded.
• 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

• 2 brushless digital servomotors with servo-drives
• 2 planetary gearboxes with minimum clearance
• gears inserted between gearboxes and 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, B axes – hydraulically
• spindle rotation clamped when changing tools – electromagnetic brake
Headstock:
• non-sliding workspindle
• spindle cavity blown with air during tool-changing cycle
• spindle driven by four mechanical lines – gears
• hydraulic shifting of each line
• headstock balancing – hydraulic
• setup of tool cooling by four jets on headstock front side
Hydraulic power pack:
• HYTOS hydraulic and lubrication set
• lubrication of all groups
• clamping X, Y, Z, B
• unclamping of the tool
• headstock balancing
Admeasurement of position:
• HEIDENHAIN digital optical admeasuring
• X, Y, Z axes - LS 187 rules
• B axis – ROD 780
• S axis – ERM 280
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 partially with sliding doors for easy handling and transport of workpieces – e.g. driving in a forklift truck, etc.

CHZ:
• tool cooling set with four 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

• 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, minimally by copy of sliding table 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
