1. Machine Features
This series Heavy Duty Horizontal Lathe can utilize high-speed steel and carbide cutting tools to finish rough or finish turning process for not only the non-ferrous metals like various structure steels, casting steels and irons, but also the external/internal cylindrical / conical/ spherical surfaces, thread of non-metal materials and all kinds of the surface of curve rotary body.
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 machine 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. Machine Bed
The machine 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<0.05mm). 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 and Spindle
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(Double /Two Carriages)
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 and Z axis are equipped with digital grating rule for measurement control.
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. 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.
G. Central Support
This part shall be mounted during slender shaft machining or boring.
H. Cooling System
Adopt circular cooling system, which makes the chips easy to remove and clean. This design makes the coolant oil easy to change.
