2.The main content of CNC machining process:
Step 1: understand the technical requirements of the drawing, such as dimensional accuracy, form and position tolerance, surface roughness, workpiece material, hardness, processing performance and number of workpieces, etc.;
Step 2: Perform process analysis according to the requirements of the part drawings, including the structural processability analysis of the parts, the rationality analysis of materials and design accuracy, and the approximate process steps;
Step 3: Work out all the process information needed for processing according to the process analysis-such as: processing process route, process requirements, tool trajectory, displacement, cutting amount (spindle speed, feed, depth of cutting) and Auxiliary functions (tool change, spindle forward or reverse, cutting fluid on or off), etc., and fill in the processing procedure card and process card;
Step 4: according to the part drawing and the crafted content, and then carry on the numerical control programming according to the instruction code and program format stipulated by the numerical control system used;
Step 5: Input the programmed program into the numerical control device of the numerical control machine tool through the transmission interface. After adjusting the machine tool and calling the program, the parts that meet the requirements of the drawing can be processed.

5. Precautions for titanium alloy CNC machining titanium alloy
Due to the small modulus of elasticity of titanium alloy, the clamping and force deformation of the workpiece during processing will reduce the processing accuracy of the workpiece; the clamping force should not be too large when the workpiece is installed, and auxiliary support can be added if necessary.
If a cutting fluid containing hydrogen is used, it will decompose and release hydrogen at high temperatures during the cutting process, which will be absorbed by titanium and cause hydrogen embrittlement; it may also cause high-temperature stress corrosion cracking of titanium alloys.
The chloride in the cutting fluid may also decompose or volatilize toxic gas during use. Safety protection measures should be taken when using it, otherwise it should not be used; after cutting, the parts should be thoroughly cleaned with a chlorine-free cleaning agent in time to remove chlorine residues.
It is forbidden to use lead or zinc-based alloys to make tools and fixtures in contact with titanium alloys, and copper, tin, cadmium and their alloys are also prohibited.
All the tools, fixtures or other devices in contact with the titanium alloy must be clean; the cleaned titanium alloy parts must be protected from grease or fingerprint contamination, otherwise it may cause salt (sodium chloride) stress corrosion in the future.
Under normal circumstances, there is no risk of ignition when cutting titanium alloys. Only in micro-cutting, the small chips cut off will ignite and burn. In order to avoid fire, in addition to pouring a large amount of cutting fluid, it is also necessary to prevent the accumulation of chips on the machine tool. The tool should be replaced immediately after being blunt, or the cutting speed should be reduced, and the feed rate should be increased to increase the chip thickness. In case of fire, fire extinguishing equipment such as talcum powder, limestone powder, dry sand should be used to extinguish the fire. Carbon tetrachloride and carbon dioxide fire extinguishers are strictly prohibited, and watering is prohibited, because water can accelerate combustion and even cause hydrogen explosion.
6.What is the Swiss-type automated machine?
The Swiss-type automatic lathe is also commonly referred to as the Swiss type lathe. It is a high-speed,high-precision, and highly automated machine tool.The Swiss type lathe can be used to process the size shown in the figure below with a roundness of 0.0002. It is difficult to achieve this with other types of machine tools.
The Swiss-type lathe does not refer to a machine tool made in Switzerland. It was originally a turning center designed in Switzerland to process small,high-precision parts used in the watch industry.
Unlike traditional lathes whose parts are fixed and the tool moves, Swiss-type lathes allow parts to move in the Z-axis direction while the tool is fixed.
As shown in the figure below, the rod-shaped blank is clamped on the guide sleeve on the machine tool, and the blank is gradually fed outward along the guide sleeve, only the part of the blank that needs to be processed in extended, which can maximize the clamping stability of the workpiece.Minimize the deformation and vibration of the workpiece and improve the machining accuracy.
In the case of additional support, the secondary shaft can be moved to a certain position to grasp the front end of the part.
The use of rotating tools enables Swiss-type machine tools to also have milling and drilling capabilities.The Y-axis of the machine tool provides a complete milling function,which is a dream function of many CNC lathes, which can greatly reduce the processing time. In addition to rotary tools, many Swiss-type lathes are equipped with drilling and boring tools on the back machining tool holder. When the part is clamped on the secondary shaft, these tools can be used to drill and boring the part to complete all parts processing.Although traditional CNC lathes can also perform C-axis rotary tool processing, the unique design of Swiss-type machine tools makes it more powerful and accurate.
