There are many CNC Machining Parts Manufacturers around us. In the industry, there are still a lot of uses. It is precisely because there are so many that it needs to be used for processing in various processing. What about a fully automatic tool setting system for precision part processing?
CNC Precision Machining Custom
CNC Precision Machining Custom is to complete a variety of processes in automatic state of the numerical control equipment, mainly about some fixed high-volume consumer operations. However, regarding the mold industry and small-volume consumer units, you should never go to the machining center. Many manufacturers buy machining centers to use as CNC milling.
The use of tool magazines is very simple in terms of the cost of the CNC system, but the spindles and tool magazines, air compressors, and various tool holders will increase the costs, and programming and adjusting the tool magazines will take a corresponding amount of time. Therefore, regarding the consumption of less than one or two hundred workpieces of the same type, it is best not to use a machining center, which has high cost and low efficiency.
Full-automatic tool setting system can be used for fine parts processing. The knife is installed one up, one button, and the machine tool automatically sets the tool. Direct processing. The error is within 0.001 ～ .0003mm, which is much slower than the automatic change time. If it is a precision part machining center, but the machine tool without automatic tool setting and the machine tool without automatic tool setting, the latter is much higher in theory than the former.
Regarding domestic manufacturing, especially mold manufacturing enterprises, it is generally single-piece consumption, and labor resources are sufficient. Therefore, regarding the processing of small batches of industrial parts, we must fully consider the application value of funds, and do not use processing centers at all times. device. What's more, there are still many problems with the tool magazines of domestic manufacturers.
CNC machining accuracy problem, what's going on?
1. Accurate workpiece size and poor surface finish
Causes of failure: The tool tip is damaged and not sharp; the machine tool has resonance and is not stable; the machine tool has a creep phenomenon; the processing technology is not good.
Solution: If the tool is not sharp after being worn or damaged, re-sharpen or select a better tool to re-set the tool; the machine has resonance or the placement is not stable, adjust the level, lay the foundation, and stabilize it; the reason for the machine to crawl is drag The plate guide rail wears a lot, and the screw balls wear or become loose. The machine tool should pay attention to maintenance. After work, clean the wire and add lubricating oil in time to reduce friction. Choose a coolant suitable for the workpiece processing. In the case, try to choose a higher spindle speed.
2. The workpiece has a taper size head
Causes of failure: The placement level of the machine tool is not adjusted properly, one is high and the other is low, and the placement is not stable; when turning the long axis, the contributing material is relatively hard, the tool eats the knife deeper, causing the phenomenon of giving up the tool; the tailstock thimble is not concentric with the spindle.
Solution: Use a spirit level to adjust the levelness of the machine tool, lay a solid foundation, fix the machine tool to improve its toughness; choose a reasonable process and a suitable cutting feed to prevent the tool from being forced to give the tool; adjust the tailstock.
