For many projects in the machine shop, coolant has become a standard tool. In fact, with hard to work metal, it is essential. However, it is possible to do metal machining with no or very little lubricant or coolant. Here is helpful information on the subject.
Why Work Dry?
Machining without coolant can provide a number of benefits to today’s machine shop. For example, when you use less coolant, your operating costs go down. Coolant can be a major expense, especially when you have to recycle or dispose of it. Lubricants and coolants contain chemicals and if you machine without them, it can create a healthier work environment.
Tips for Dry Metal Machining
The following tips can help you save significantly on coolant without sacrificing quality:
Begin with Lathe Operations
Milling or turning operations may be the easiest methods to start with. Heat buildup is less likely due to exposed cutting surfaces. In addition, chip removal is simple, due to the forces of gravity.
Use the Best Cutting and Boring Tools
Without coolant, you increase wear and tear on your tools. This is caused by added friction. To counteract this problem, use the sharpest and most dependable cutting tools. Instead of high speed steel for some jobs, you should consider carbide tools. If the job normally calls for carbide tipped cutting, you might want to use diamond tipped tools.
Mist Lubrication Techniques
Some metal machining jobs will go easier if you use coolant or lubricant. However, in many cases, you can use mist lubricant instead of flooding the cutting area with coolant. Misting may provide adequate coolant and protection from excessive heat. This can help you cut down on coolant costs and limit wear and tear on your tools. However, the kinds of metals you use will depend on which coolant reduction method you should attempt.
