how important is staff training

how important is staff training!

SYM Saff Training


With the development of science and technology, the progress of society, 'things' have higher requirements for people, the combination of people and things is often in dynamic contradiction. You are a competent worker today, if you don't keep on learning, you may be out of date next year. People and things are not coordinated,an enterprise wants to be invincible in the competition in modern society, it must pay attention to the staff training.

Staff job skill training is a kind of productivity, enterprise staff through continuous training, skills will have a new promotion, so they have a further specification in the production operation, also further improve the work efficiency. The enterprise production equipment can play out the biggest effect, of each process will be more fluent, so that the production cost savings, eventually form ' training-enhanced skills- enterprise development-retraining' of a virtuous cycle. Staff training is a win-win activity that benefits both enterprises and employees. An enterprise that pays attention to staff training will have a better social impact on improving the quality of the whole society.

Staff training effectiveness, it refers to the benefits obtained by the company and employees from the training. For employees, revenue means to learn new knowledge or skills. For the company, revenue includes the increase of customer satisfaction.

Generally, the training effectiveness are usually shown in the following aspects.

1.Increase of employee knowledge.
The trained employees have the basic knowledge necessary to complete their own work, and the employees can have a good understanding of the basic situation of enterprise operation, such as the enterprise's development prospects, strategic objectives, operation policies, rules, and regulations.

2.Improvement of employees' skills
After training, employees have completed the skills necessary for their own work, such as negotiation skills, operation skills, and interpersonal skills.

3.The change of employees' attitude
Through the training, the company has established a relationship of mutual trust with employees.enhanced their spirit, cultivated their teamwork spirit,and increased their initiative to integrate into the corporate culture.

4.Changes in employee behavior
Employees improve knowledge skills and work attitude positive change, mainly reflected in the employee return to work after the operation, the application of new knowledge and skills to practice, to solve the difficulties and problems encountered in the previous work, the transformation of the original work attitude, enhance the enterprise master the sense of responsibility and team cooperation consciousness, actively contribute to enterprise development.

5.Increase of enterprise benefits
The staff can timely apply the training results to work, improve the quality of product and service, reduce the production cost, finally improve customer satisfaction, and increase the efficiency of the enterprise.

To sum up, the innovation of an enterprise can be realized only when the training is completed and improve through continuous learning.

Choosing the right material for your custom machined part

Choosing the right material for your custom machined part.
Custom Machined Parts



Concerning custom machined part,choosing the right material is one of the most important thing,to save your money.

Here are 4 points for choosing the metal or plastic that is right for your custom machined part.


1. What will your machined part be used for?
The environment where your machined part will be used will have the most significant impact on material selection.If you are using machined part outside or in wet environments,use stainless steel as opposed to carbon steel due to avoid rust.

Design specifications like stress load,tolerance,and types can also impact your choice of material.

2. Do you care about the weight of parts?
Generally, standard aluminum alloys like AL6061 are great, low density options to keep weight down if a metal is required.Plastics like delrin (POM) and ABS can help keep the weight down even more if tradeoffs in strength can be made.


3. Strength and heat resistance
There are many different ways to measure material strength including tensile strength, material hardness, and wear resistance.Selecting the types of strength your design to get the best material for your custom machined part.

Very low or very high temperatures will also restrict you from using certain materials. Environments where the temperature fluctuates are particularly important to consider, since some materials will expand or contract even in environments where the temperature difference is small.

4. Cost
Overall cost of your project will influence your choice of material. the more material your part uses, the more expensive it will be. Special materials and strong materials, such as titanium,carbide steel etc.

Slecting the right precise machining process

For precision machined parts,the precise machining process directly affects the quality of products,according to different tolerance requirements to write different precise machining process, to ensure the quality of machined parts, a good machining process is very important.

SYM Precise Machining Process


At SYM Precision Machining, our operation standard is the production drawing provided by the customer. Due to meeting the tolerance requirement of the drawing, write the most economical precise machining process, we require the professional technical level of the process engineer to be very high.

1. According to the size accuracy of the drawing to determine the cutting method, such as turning, milling, grinding, wire cutting and EDM, etc.

2. According to each cutting charateristic to determine the process, for example, machining the parts as below picture, the precise machining process would be.

1) Turning outside
2) Drilling the center hole
3) Machining end surface
4) Chamfering
5) Deburring

Precise Machining Process - Turning 


3. In order to improve the production efficiency, reduce the damage of parts, but also consider the times of clamping, as far as possible to reduce the times of clamping parts in the machining process.


The same part, according to the different quantity of production, its process is also different. CNC machining is commonly used for mass production, the traditional machining is generally used for small quantity production, the cost would be higher if need use CNC machining for small quantity production.

The modification and supplement of precise machining process regulations must go through careful discussion and approval.

10 tips for thread tapping in precision machining

Unlike most commonly used turning, milling and drilling tools, the cutting edge and the opposite surface of the tapping are relatively weak, and the cutting edge is prone to collapse or crack, especially when processing steel materials.



Therefore,let's learn 10 tips for thread tapping in precision machining.

1. The hole of the bottom hole of the thread on the workpiece should be chamfered,both ends of the thru thread hole should be chamfered.

2. The position of the workpiece clamp should be correct, try to make the centerline of the threaded hole placed in a horizontal or correct position, so that the tapping can easily judge whether the tap size is perpendicular to the plane of the workpiece.

3. At the beginning of tapping, try to put the tap straight, and carefully check and correct the position of the tap.

4. When tapping, every 1 / 2-1 turn of the tapping, it should rotate about 1/2 turn, so that the swarf can be easily discharged.

5. When tapping blind thread holes,to drop out the tap and remove the swarf in the hole.

6. When tapping the screw holes of plastic materials, lubricating coolant should be added. For steel materials, motor oil or concentration-bound emulsions are generally used.

7. When changing the screw tap during the tapping process, you must first screw into the thread hole by hand. When you can no longer screw in, continue to tap. When the tapping is completed, it is best to drop out it by hand to ensure that the quality of the tapped thread is not affected.

8. When tapping by machine,the screw tap and thread hole should be kept coaxial.

9. When tapping by machine,the calibration part of the tap cannot be all over, otherwise,it will produce messy teeth when the tap is dropped out.

10. When tapping by machine, the cutting speed is 6-15m/ min for general steel, 5-10m/min for quenched and tempered steel,2-7m/min for stainless steel,8m/min for cast iron.
