Special Designed Horizontal CNC Lathe for Sugar Industry (CG61160)

Product Description

China Professional Horizontal CNC Lathe Machine for Sugar Industry, Machining Cylinders, Mill, Shaft, Turbine, Pipe, other long work-piece.
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. Double Carriages:Frame-type tool plate & 4-stations Automatic Tool Rest

The unique design with double carriages can realize not only separate control, but also realize turning parts simultaneously. AC servo motor for X Axis is connected directly to the ball screw through the precision reducer, which ensures a rapid transmission and high accuracy and rigidity. There is a double teeth sticks with gap elimination structure in Z direction of tool carriage, equipped with Grade 5 gear rack to guarantee a high accuracy and rigidity.

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. The headstock and guide-rail adopt 2 sets separate lubrication system. The headstock adopts closed-type oil-line lubrication. There is a visible window for observing and analyzing the oil status. The guide adopts automatic lubrication system and it can be lubricated automatically once every 20 minutes by independent electrical lubrication pump. (The user can also set up the lubrication time per actual demands). When the oil level is below the red line, the system will be automatically alarm.

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.

F. Open-type Central Support(2 pieces)

The open-type central support is mainly used for bearing/supporting heavy work-piece during machining process. It greatly reduces the wearing of machine to protect the equipment, but also increase the machine stability during machining process. The central distance of central support can be adjustable for supporting different diameters work-pieces.
