Some characteristics and considerations of a non-standard customized production plant

Non-standard custom processing is relative to the standard parts, before we understand the non-standard parts and take a look at what is the standard parts. Standard parts refer to the structure, size, drawing, marking and other aspects are completely standardized, and commonly used parts produced by professional factories, such as threaded parts, rolling bearings and so on. The broad standard parts include standardized fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. The narrow definition includes only standardized fasteners. The domestic commonly known standard parts are short for standard fasteners, which is a narrow concept. In addition, there are industry standard parts, such as automobile standard parts, mold standard parts, etc., which are also generalized standard parts.

Non-standard, multi-variety, small-batch customized production refers to the production of non-standard products according to the specific needs of customers. Non-standard, multi-variety, small-batch customized production plants need to maintain the flexibility and efficiency of production while ensuring product quality. This requires a high level of competence and effective management strategies in design, production, supply chain management, quality control and customer service. With the increase of market demand for personalized and customized products, this production mode will be more and more attention. Compared with the traditional large-scale and standardized production, this production mode pays more attention to the individuation and differentiation of products. Honscn Precision Technology Co., Ltd. can meet this production process and time requirements.

• Technical training: Regular technical training for employees to ensure that they can operate advanced production equipment and technology.

Non-standard customized products are mainly machined by automatic lathes.

Automatic lathe is a kind of high performance, high precision and low noise automatic lathe, which is an automatic machining machine tool that controls the machining program by CAM. In addition, there are also some CNC automatic lathes and pneumatic automatic lathes and center-based automatic lathes, the basic core is that you can automatically process the same product for a long time after certain Settings and adjustments. Suitable for copper, aluminum, iron, plastic and other precision parts processing and manufacturing, suitable for instruments, watches, automobiles, motorcycles, bicycles, glasses, stationery, hardware and bathroom, electronic parts, connectors, computers, mobile phones, mechanical and electrical, military and other industries batch processing small parts, especially more complex parts.

Features: High performance, high precision, low noise

Application fields: instrument, clock, automobile, motorcycle, etc

1, the core type of processing process: through the simple clamp clamp processing materials, materials move forward, and the tool does not move, through the linear movement of the tool or swing movement to process parts.

2, the machining process of the cutting tool: the workpiece is clamped with a simple clip, and the workpiece is processed by moving around and around the turning tool.

3, cutting CAM automatic lathe is equipped with 5 knives. Tool holder in order of 1, 2, 3, 4, 5 knife each group of tool holder can be installed 1-2 knives, 1 and 5 are turning outside diameter, 2, 3, 4 are mainly grooving, chamfering, cutting and other processes. 2 tail shaft, 2 drill bits, 1 tap and 1 die can be cut at the same time, and can also be tapped, milling, die, embossing and other processing. Without manual operation, complex parts can be synchronized to the outer circle, spherical surface, conical surface, arc surface, step, grooving, embossing, drilling, tapping, die, cutting and other processes, the whole process can be completed by one processing.

4, the size control accuracy is high: the precision of the machine spindle can reach 0.003mm, the fine adjustment of the slider is controlled by the micrometer, the size control accuracy can reach 0.005mm, and the spindle speed is within 2000-8000RPM. The minimum cutting feed can be controlled to 0.005, and the roughness of parts (copper parts) can reach the minimum Ra0.04-0.08.

5, automatic feeding: the feeding mechanism automatically feeds to the main shaft, the automatic stop alarm after the material is finished, the processing process does not need to manually look at the material, to achieve a fully automated production and manufacturing process. One operator can operate multiple machines at the same time.

6, high production efficiency: the machine control the processing process through the CAM, the CAM each turn to complete a processing process. CAM speed 1.0-36 RPM, can be adjusted according to different machining parts, can be processed about 30 parts per minute, because 5 knives can be simultaneously cutting, processing efficiency is very high, is the general CNC computer lathe and instrument lathe can not be matched.

What causes the surface roughness of automatic lathes?

1, the center frame guide sleeve quality is poor

• The inner hole of the guide sleeve of the automatic lathe is rough, the diameter is oval, and the diameter is taper. These can cause instability during the cutting process and reduce the quality of the watch. The quality of the center frame guide bushing is very important for surface roughness. Adjustment should be carefully checked, found problems should be replaced or repaired.

2. The CAM surface is rough

• The surface of the CAM is rough or convex. The tool rotation will produce a slight shake, affecting the quality of the machined surface. This may be caused by the manufacturing quality of the CAM, but in general, the main reasons include CAM contact wear, poor lubrication, CAM surface scratching and so on. This problem can be solved by repairing worn cams and CAM contacts.

3. The clearance between the guide sleeve of the center frame and the cross bar is too large

• The fit gap is too large, resulting in the change of the rotation center of the part during turning. The gap must be kept as small as possible because the cutting force inevitably causes the part to jitter, which affects the machining quality. Please make the adjustment smaller.

4. The blade is worn

• Automatic lathe blade wear is one of the most common causes. When cutting metal, the sharp cutting edge of the turning tool is used to remove excess material from the part. When the cutting edge of the turning tool is worn, the cutting conditions will change, the cutting force will increase significantly, the turning surface will become orange peel, and the surface roughness will increase. In general, sharpening tools will improve it significantly. In normal production, the main blade should be sharpened every 4 to 8 hours.

5. Tool center too high or too low

• Generally, the diameter of the parts processed by automatic lathes is relatively small. The tool center is very sensitive to the surface roughness of the part. Inaccurate centering will affect the cutting conditions. The change, especially the change of the tool center elevation, has a more obvious effect on the surface roughness. For this reason, the tool center needs to be precisely adjusted when machining small diameters.
