How Electro-Chemical Machining Works
Machine tool builder EMAG has produced a very nice video that explains and illustrates how the electro-chemical machining (ECM) process is able to perform simple deburring operations as well as produce precision surfaces and shapes.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
To make the transition to hard turning, you'll need to switch from carbide to CBN inserts, but that is easier (and more economical) than you might think. It's making the jump to much higher surface speeds that might scare you off. It needn't. Here's why.
