Siemens 828d Control Horizontal CNC Lathe Machine with Drilling Milling Functions

  Multi-functional Heavy Duty Horizontal CNC Lathe Machine with milling & drilling functions for turning sugar mill cylinder , crankshaft, rubber roll, mining oil pipe,wind power cylinder.   This is specially design heavy duty horizontal lathe machine with drilling and milling functions for sugar mill cylinder machining. The customer use it to turning 8 meter long cylinder with 40 T weight. It can be finished all machining processes by one lathe machine, which help customer to save work-piece clamping time, upload and loading time, that greatly improve machining efficiency. besides, it also save input cost of machine quipments. otherwise, customer need buy 2 different machines. one is lathe machine, another is drilling machine. This special technology is designed by our company  and obtained national patent also.   1. Outstanding Characteristics of cnc lathe machine, heavy horizontal lathe. 1). Carry Load as Heavy as Possible : Internationally forerunner computation technologies and optimized finite element analysis methods are adopted and the selected materials are suitable for the design .2.). High Rigidity, Stability and Precision Maintenance:  All castings are made of high-strength meehanite HT250. 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. 3.) One-piece structure 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.4.) 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
