HT250×100/80-NC(III)


HT250×100/80-NC(III) CNC HEAVY-DUTY HORIZONTAL LATHE
Description
1.This machine is suitable for machining ferrous-metal, non-ferrous metal or part non-metal components with carbide alloy or porcelain cutter, on the machine, cylindrical turning and boring, taping, surfacing, curving, slotting, threading as well as boring can be carried out roughly and finely..
2.The bed of the machine is of separate structure with workpiece bed and carriage bed to make machine under the best condition of being forced so that deformation of workpiece bed will not affect the carriage ones and reduce vibration upon headstock and carriage, and improve machines' anti-vibration property and operational accuracy carriage bed guideway is fixed with extendable stainless steel cover or partial guidance board for workpiece bed ones.
3.Main drive is driven by D.C motor through two step mechanism to reach speeds range for spindle,
4. Spindle of headstock is through structure and supported by high-precision double-row short cylindrical rolling bearings with adjustable radial clearance and has best supporting diameter and span because of optimized design so as to improve it's swiveling accuracy and static, dynamic rigid. Center is of short taper shank with flange structure to improve connecting rigid between center and spindle.
5. Carriage of the machine adopted hydrau-static guideway with constant flowing in transversal and longitudinal direction. Ball screw is used in transversal direction, for longitudinal ones, using hydrostatic worm rack transmitting pair or imported high precision double gear-rack transmitting pair processed by hardened and grinding in order to improve moving accuracy and stable transmission and transmitting efficiency.
6. Tailstock is of entire box shaped structure, shaft in quill adopts high precision double-row short cylindrical rolling bearings with adjustable radial clearance, and center is of flange locating structure for cone to make tailstock get good rigidity. Quill and tailstock are transmitted mechanically and clamped or released automatically, and they are fixed with hydraulic measuring device.
7.CNC system adopts SIEMEN'S or FANUC, other CNC systems can also be selected by customers' requirements.
8.According to customer's demands, the followings can be provided that are angle-dividing and feed for main spindle, grinding, cooling, tool presetting inside machine, workpiece automatic measuring for parts size as well as hydrostatic steady rest.
