HARD MACHINING
Difficult-to-machine materials (“Hard Machining”) require high-performance coolant technology for faster cutting, longer tool life, and better surface finishes. Cutting superhard, abrasive, and low thermal conductivity materials such as tungsten carbide, nickel-based alloys, titanium, and ceramics generates a lot of friction and heat. Conventional flood coolant schemes using straight oils or water-oil emulsions provide unnecessary trade-offs between optimal lubricity and cooling power. Conventional MQCL (minimum quantity cooling lubrication) schemes using air-oil aerosols cause premature wheel wear and poor surface finish due to inadequate heat management, low surface cleaning capacity, and insufficient chip evacuation. With increased cutting speeds and depths of cut, both conventional flood and MQCL coolant schemes can be ineffective or result in less-than-optimal hard machining productivity and quality. Higher friction and heat lead to faster abrasive wear, dimensional control problems, burning, poor surface finish, more frequent wheel dressing, or the need for costly post-finishing and cleaning operations – all representing lost cash flow.
Our Kutter Kooler™ systems significantly increase the productivity and profitability of your challenging machining operations, such as drilling, milling, and grinding. The Kutter Kooler systems produce and project CO2-based Dry, MQCL, and VPCL (Vapor Phase Cooling Lubricant) metalworking fluids into the cutting zone – external or through tool sprays. CO2 metalworking fluids are fully adjustable combinations of compressed air (propellant gas and oxygen), minimal amounts of dense micronized CO2 particles (adjustable 1.5 to 8 lbs/hour), and adjustable amounts of oils and additives (adjustable 50 to 150 mls/hour), or your standard lubricant. Kutter Kooler systems provide considerable gains in productivity, quality, and profitability. The Kutter Kooler system uses a centralized CO2 coolant (R744) supply system that supports multiple machining tool adaptations using standard or machine-customized cooling-lubrication applicators.
MACHINING WITH ADVANCED CO2 MACHINING SPRAY TECHNOLOGY
WHAT DO OUR CUSTOMERS SAY
The purpose of surface cleaning is to remove deposits that might cause damage through abrasion, absorption of acidic gases, or serve as medium for mould growth.
Simple dry cleaning of surfaces using erasers and sponges requires contact with surface which might also cause alteration of surface properties (flattening, eraser residues). With respect to basic requirement to avoid material degradation an alternative non-contact method might be CO2 snow jet cleaning performed using a Precision Spray Cleaning Pen (SnoPen SP 2000, Cleanlogix).
Artificialy soiled samples of wood-based and cotton-based paper were cleaned by the CO2 snow jet with a carbon dioxide flow rate of 3.0 g/s and a nitrogen flow rate of 1.4 l/s and by the nitrogen jet at the same flow rate. Paralel samples were cleaned by traditional mechanical cleaning methods. The effect of treatment was evaluated by optical microscopy.
The results showed that the CO2 snow jet cleaning effectively removed particles in the lower layers of the paper surface, including interfiber spaces.
The CO2 snow jet cleaning compared with the mechanical dry cleaning showed similar effectiveness without any adverse effects on the paper surface. It was proved that the CO2 snow technique is a suitable method for cleaning common types of paper materials.
