Large thin wall volume precision machinery parts processing precision machining
process, the occurrence of error and impact on the quality of precision mechanical parts is inevitable.
We only take the corresponding measures to minimize machining error, can effectively improve the accuracy of precision machining and quality.
Xavier company during 15 years of precision machinery parts processing, often meet customer let us processing large sheet.
And surface structures have higher quality requirements, plane precision demand is high.
But the characteristics of the thin wall, because of the large volume to cause more attention when precision machinery parts processing, set reasonable technological process, and in strict accordance with the process to operate.
Its process includes the blank preparation, machine tool parts with card to align, order processing, with the adjustment of cutting tool knife multi-channel processes, such as finished and semi-finished products lifting handling and placement of items, each working procedure will affect the quality of precision machinery parts processing, the work must be done well.
Raw material preparation: raw materials,
Preparation is to grasp the precision machining quality of the first pass, must execute unqualified raw materials,
Don't put into production.
Precision machining before must make confirmation for raw materials, such as material requirements for 304 stainless steel, steel must with effective purchasing, the traceability of material;
Raw material after cutting blanking correction flatness, the flatness 1 or less.
In large sheet of card and find it is an important link of the big board processing precision guarantee, each step is the key card, method, sequence of card directly affect the precision machining precision of the big board.
When the clamping must die clamp, prevent the workpiece in cutting force, gravity, inertia force under the action of shift or shake, so as not to damage the workpiece positioning.
Large sheet of precision machinery parts processing is a key link in the process of decision product qualified, should choose the reasonable processing order, separate the roughing and finishing, economic operation, a benchmark, the finished surface twice.
If the processing capacity is too big, should be uniformly distributed points and/or add a pre datum processing (
That is once more turn)
Large sheet of finished surface quality inspection, finished in the milling and loosen all pressure point (
Artifacts in the free state)
On the machine table.
Test projects are: the flatness and roughness, thickness, record all pressure points measured data.
