Good Price and Design From CNC Machining Suppliers
How to get a cheap price with a good design from CNC machining suppliers? In this blog, we will share some experiences what kind of good design that we can quote a cheap price..
First, we have to know what it is a good design. From the view of customer, a good design must meet the requirement of the function ,accurate dimension and cheap price. From the view of supplier, a good design is having detail information, such as material, tolerance, dimension, and with an eye toward the machining process which can make price cheaper. So cheap price is a key point.
If the designer is thinking about the way the part will be machined makes the process easier for both the machinist and for customer’s budget.
Below are tips on design from CNC Machining Suppliers Creatingway
Avoiding end mill chatter.
When you make a design, it is better to avoid too deep depth. Since the end mills works best when they are rigid. The deeper the depth is, the more likely the end mill will chatter. And when it is chatter, it will result in a poor surface finish. That’s why we tell customers that we could not do such kind of depth, is it ok to make the depth less deeper?
20 or .30 to any corner with a standard diameter
Sometimes customers complain that the corner of the parts didn’t have a good surface. That’s because the designing parts that have corners the same size as a typical end mill diameter. If the designer add 20 or .30 to any corner with a standard diameter, it will lessen the surface area coming into contact with the part.This helps to prevent the chatter and maintain a good surface on the part.
Tapping a hole to a depth of 1-3 times of diameter
Even a hole can save a lot of cost of machining. The designer should know this point well. Since for maximum strength, it is just necessary to tap a hole to a depth of 1-3 times the diameter. Any deeper is unnecessary and costly. But how about a through hole? We can drill through and specify threads as needed.
The simpler the design is, the cheaper the price is.
A complex design means high risk of machinist. And all the machining suppliers will charge a premium for more complicated parts. This is because if a mistake occurs ,it is much more expensive to redo a complex part than it is to redo a simple one.
Good design and cheap price is the aim of both customers and suppliers. We hope we can learn more from our experience of business with customers and become more and more professional.
