High Quality Horizontal CNC Lathe Machine
For Machining workshop facilities,Shaft,Pipe,Cylinders,wheel turbine, Long Shaft,Tire Mold, Railway Parts,Wheel Hub Turbine,etc
A. Main Components
Internationally forerunner computation technologies and optimized finite element analysis methods are adopted and the selected materials are suitable for the design so that the lathes can carry loads as heavy as possible.
All castings are made of high-strength meehanite HT250. Therefore, the lathe has proved high rigidity, stability and precision maintenance, which is particularly suitable for heavy cutting. All large castings stand the test of annealing and vibration aging and internal stress is eliminated, so the overall precision is greatly enhanced and processed parts are found with high geometric accuracy.
The lathe is in one-piece structure and made of meehanite, greatly enhancing its abrasion resistance, and the internal force elimination process produces high vibration resistance and considerably enhances stability. The cross-shaped base and rectangular bearing structure ensure high structural stability and permanently stable quality.
B. Lathe Bed
The lathe bed is in fixed heavy cutting structure, including rectangular hard rails tested by high frequency heat treatment and high-precision surface grinding (straightness in full stroke<0.03mm). Turcite-B is pasted on the sliding surface in order to enhance the rail's smoothness and wearing resistance. The widened hard rail design can provide required resistance and stability for heavy cutting.
C. Headstock & Main Shaft
The headstock, made of high strength and high rigidity keel rib, is in special cage shape, and the gearbox includes Class P5 grinding gears, which can provide desirable driving accuracy and greater torque (nearly 1000Nm).
Incorporating German AM technologies, the main shaft is made of chrome-molybdenum alloy and proves high precision, high rigid and desirable deformation resistance after rough/finish machining, carbonization, aging treatment and precision grinding. The motor figures high output (15kw) and the max. rev. is 1500RPM. After the main shaft assembling is completed, the entire assembly shall be calibrated by dynamic balance test. The independent lubrication will further enhance the stability of the headstock during operation.
D. Carriage
With the structure of frame type reinforcing, strong bearing capacity, controlling AC servo motor to connect directly to the ball screw through the reducer. The X axis respectively adopt the precise C3 level of ball screws with the diameter φ63 mm (φ63XP20) and P4 level of bearing, and the positioning is very accurate. The ball screws are sealed by the sheet metal, and not easily affected by the cutting water and iron erosion. The advantages of driving fast, stable accuracy, eliminating the backlash, improving the reversing rigidity, allowing the unparallel angles, eliminating the axial errors, etc., have a great improvement on the positioning of the machine tools.
E. Lubrication
The automatic lubrication system includes a closed-pole continuous oiling machine CEVB 2.5L, which can ensure all target points can be fully lubricated; sliding surfaces and ball screws are allocated according to the corresponding oil ways to control oil mass. The oil circulating lubrication time can be determined as required. Low oil level control devices are also included.
F. Cooling System
Adopt circulating cooling system to ensure a easy and simple chips cleaning and oil replacement.
G. Chips Cleaning System (Optional)
Chain slat type chips cleaning system is mounted in the back of bed, which ensures a convenient and flexible chips in the machining area.
H. Wheel Cutting Tool Storage
Standard 4 Position cutting tool Storage is mounted on the tool carrier for precision turning process.
I. Tailstock
The tailstock consists of two parts: the upper one includes a sleeve moving mechanism, spindle assembly, and a shaft centerline adjustment mechanism, with a rectangular head in the rear, which is designed to lock the sleeve manually; and the lower one includes a tailstock fast-moving motor and a locking mechanism, with the main shaft installed on the high-precision radial clearance-adjustable double-row cylindrical roller bearing in the sleeve, rendering the high-precision rotating top on the tailstock. However, in order to satisfy certain special requirements of the machining process, it is feasible to transfer the plug board from the flange groove in the front of the sleeve to the groove near the front end of the main shaft in order to fix the main shaft and obtain a dead center. The rear end of the main shaft is connected with the sleeve via a disk spring to avoid any damage to the mechanism rising from thermal expansion of the work pieces.
J. Centre Carriage
Mount this centre carriage on the machine when machining long shaft or boring holes.
