Advantages of 5 axes machine

At present, the homogeneity competition in the manufacturing industry is becoming increasingly fierce. Only with unique core technology, achieving higher production efficiency under the premise of ensuring quality, or making high value-added products that others can't, can it stand out. It is in this context that five-axis machining is favored by more and more manufacturers.

Why choose five axis?

The five-axis machining center adds two of the A/B/C rotary axes on the basis of the three-axis, which is characterized by the linkage relationship and structure of the two additional rotary axes and the linear axis.

Then why more and more manufacturers tend to choose five-axis? The main reasons are as follows:

1) The new product update cycle is shortened, the cost is forced to reduce, and the traditional technology cannot meet the delivery requirements.

2) Product quality and quantity depend on labor, and labor costs are getting higher and higher.

3) Electrical discharge machining needs to process electrodes. The process cost is high, the efficiency is low, and the quality is poor. Five-axis can replace it.

4) The maturity of the three-axis processing technology has led to fierce competition for homogeneity.

The core values of Makino Five Axis

(1) Machining accuracy

For some complex multi-faceted products, it is more difficult to achieve high accuracy in three-axis machining, and the manual intervention time is longer, while five-axis machining can achieve rapid positioning processing, mainly from the following aspects to increase the processing accuracy of the product:

1) Introduce a five-axis fixture.

2) Reduce the clamping process.

3) There is no manual multiple clamping, and the clamping error is reduced.

4) Only need to find the coordinate system once to reduce manual errors.

5) Reduce the length-diameter ratio of the tool and reduce the risk of snapping a knife.

(2) Surface quality

Five-axis can improve the surface processing quality of the workpiece from the following angles:

1) Use a tool with a relatively short length to improve machining stability.

2) The process of reducing the discharge makes the entire surface more uniform.

3) Use the side edge processing of the ball knife to improve the surface quality of the workpiece.

4) It can avoid the reversing point of the 3-axis and improve the surface quality.

3) Processing efficiency

Five-axis can improve the processing efficiency of the workpiece from the following angles:

1) Use a tool with a shorter tool length and diameter to increase the processing feed.

2) Use five-axis linkage machining to reduce the process of electrical discharge.

3) Use the side edge processing of the ball cutter, and use the multi-edge cutter to increase the processing feed.

(4) Makino five-axis QCD concept

High precision and high rigidity five-axis + multi-blade ball knife:

Quality: 1 point use ⇒ Machining accuracy is improved to eliminate the influence of tool accuracy.

Costdown: Full-blade use ⇒ Reduce costs. Divide the full-blade use area of the ball knife, use all effective blades, extend tool life and reduce tools.

Delivery: Multi-blade tool ⇒ Shorten processing time. The number of cutting edges increases, the feed is doubled, and the processing time is shortened.
