Maintain a learning attitude in order to continue moving forward! This is especially true in the traditional mechanical processing industry, where continuous review of the old and learning of the new, continuous optimization of mastered technologies, and learning of new technological processes are necessary to better reduce processing costs and improve processing capacity efficiency for enterprises.
Today, let's follow the editor to learn about the knowledge of "chip breaker"!
一、 What is a chip breaker?
The chip breaking groove on the blade refers to the various "reliefs" on the front cutting surface of the blade, which can break the chips, guide the direction of the chips, reduce the processing temperature of the tool, and extend the tool life during cutting.
二、 Why can't we reduce the number of reliefs?
What is the reason why people are willing to use expensive laser engraving machines to create small "reliefs" on a blade? During machining, chips are prone to entangle with the tool and workpiece, causing damage to the tool and machining surface, especially on automated machine tools such as CNC, where chip handling is even more important.
(Entanglement: The flowing long hair of the workpiece is a nightmare for machinists!)
三、 How to deal with these 'messy posts'?
One: Increase the bending of chips to create a certain degree of cracking, making them more prone to breakage.
Secondly, control the flow of chips so that curled chips collide with unprocessed workpieces or the back of cutting tools and break.
Processing principle
The chips processed through the chip breaker, washing, shearing, and blowing have become very short.
四、Summary: The Function of Chip Breakers
01 Make the chips break or control the shape of the chips (note: the selection of chip breaking grooves needs to consider different processing materials and processing characteristics). 02 Reduced the contact area between chips and the front cutting surface, thereby reducing cutting heat. 03 Forming a specific angle on the front cutting surface and combining it with the angle of the tool holder to form a more suitable cutting angle. 04 Increase the strength of the cutting edge, reduce cutting resistance, and extend tool life. 05 Control the flow direction of chips to ensure that the machined surface of the workpiece is not scratched by chips. When facing cutting problems in machining, choosing tools with chip breaking grooves can effectively improve the chip breaking effect.
