The current CNC machining types can be divided into mass production, multi-species small batch production, and single-piece production. In today’s mostly multi-species small batch CNC processing, this production method in the CNC machining manufacturing industry has become increasingly important.
With the intensification of market competition, the market environment in which modern enterprises are located has undergone profound changes, and enterprise competition is increasingly emphasizing competition based on customer demand. Therefore, the production methods of enterprises gradually shift to various advanced production modes based on flexible and automated production, and the multi-species and small-lot CNC machining production methods occupy an increasingly important position. Suppose you often need to find CNC machining factory cooperation to produce parts products. In that case, you need to understand the concept of multi-species, small-lot CNC machining production, its characteristics, and how to distinguish the selection of a suitable CNC machining factory.
Multi-species, small-lot CNC machining production concept
Multi-species, small batch CNC machining production refers to a production method in which the types of processed products (specifications, models, sizes, shapes, colors, etc.) are more in the specified production period, and the number of each type of product produced is less.
Generally speaking, this production method is less efficient, more costly, less easy to automate, and more complicated to plan and organize production compared to mass production methods. However, in the market economy, consumers diversify their hobbies and pursue advanced, unique, and popular goods that differ from others. To expand the market share, enterprises must adapt to such changes in the market. Enterprise product diversification has become an inevitable trend.
Multi-species, small-lot CNC machining production characteristics
1. Multi-species parallel
As many enterprises’ products are configured for customers, different products have different needs, and the enterprise’s resources are placed in multiple varieties.
2. Resource Sharing
Each task in the production process requires resources, while the resources that can be used in the actual process are very limited. For example, the problem of conflicting equipment often encountered in the production process is caused by sharing project resources. Therefore, the limited resources must be properly deployed to meet the project requirements.
3. Uncertainty of order results and production cycles
Due to the instability of the customer’s demand, the planned nodes, and the inconsistency of the cycle of human, machine, material, method, environment, etc., the production cycle is often uncertain, and projects with insufficient cycle time need to take up more resources, which increases the difficulty of production control.
4. Variable material requirements, resulting in serious procurement delays
Due to order insertion or change, it is difficult for out-processing and procurement to respond to order delivery time. The small batch and single source of goods lead to great supply risk.
Difficulties of multi-species, small-lot CNC machining production
Multi-species, small-lot CNC machining production mode in enterprise practice will also encounter many problems, generally the following problems.
1. Multi-species, small-lot production, mixed scheduling difficulties
2. Can not be delivered on time, too many “fire-fighting” overtime
3. Orders need too many follow-ups
4. Production priority frequently changed, and the original plan can not be implemented
5. Inventory keeps increasing but often lacks key materials
6. The production cycle is too long, and the lead time is infinitely inflated
How should enterprises identify the production quality of small-batch CNC machining factories to meet the requirements?
Generally speaking, CNC machining because the product is constantly changed, often product change and production debugging work, in the process of change, the need to modify the equipment parameters, tooling, fixture replacement, CNC program preparation or call, etc., the slightest error or omission. Sometimes workers have just ended the final product; the new product has not yet fully mastered or remembers the relevant operating principles, still “immersed” in the previous product operation, resulting in substandard output and product scrap.
In fact, in the production of small batch CNC machining, most of the scrap is in the product change in the commissioning equipment. Reducing the scrap in the commissioning process is particularly important for multi-variety small-batch CNC machining production.
In addition, the characteristics of multi-variety small batch production increase the difficulty of product quality control; to ensure the quality of multi-variety small batch CNC machining production can be stable, enterprises seeking cooperation with CNC machining factory to pay attention to whether the enterprise has established detailed operating instructions and the implementation of the “prevention-oriented” management principles, in addition, to see the factory Whether the introduction of advanced management concepts to improve the management level.
Because many CNC machining factory in, the process control, although there are process procedures, equipment operating procedures, safety procedures, and job responsibilities, poor operability, and is too cumbersome, coupled with no monitoring means, the implementation of the degree is not high. The operation records many enterprises have not conducted statistics and have not developed the habit of checking the operation records every day. Therefore, many original records are just a pile of waste paper.
Although many enterprises have passed the ISO9000 quality management system certification, they still implement the process-specific inspection system and stay at the stage of relying on quality inspectors to keep an eye on things instead of looking for reasons from process control and management. Such a factory is more difficult to ensure the quality of production. So be sure to pay attention to the review of the factory; the best is to visit the site.
Summary
In this article, through the concept of multi-species, small batch CNC machining, characteristics and how to distinguish a CNC machining factory will cooperate after cooperation can provide stable ways and means of quality parts.
