Special Professional CNC Lathe Machine for Automotive Wheel Refurbishment
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, which can provide desirable driving accuracy and greater torque 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. 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.
