5 HIGH PRESSURE COOLANT SYSTEM Ⅰ Necessity of High Pressure Coolan Recent interest on high pressure fluid grew as machine tools tend to become high speed and high precision. Low pressure (below 14kgf/ cm2 ) cutting fluid is blocked by the vapor barriers created by machine tool s cutting speed. It loses cutting fluid function before it enters the cutting zone because of evaporation. On the other hand, high pressure (over 20kgf/ cm2 ) cutting fluid can reach the cutting zone to achieve the following: 1. Smooth lubrication and cooling effect 2. Improvement in cutting capability 3. Improvement in tool lifetime by removing the phenomenon of chip re-cutting 4. Improvement in cutting surface roughness 5. Smooth chip removal effect 6. Deburring effect 7. Smooth cutting and cutting capability improvement in special processes such as deep hole processing and difficult-to-cut material processing In case 70kgf/ cm2 high pressure cutting fluid is used in the cutting of difficult-to-cut materials, the tool manufacturer test shows the following results compared with the use of common cutting fluid % reduction in cycle time because of an improvement in cutting speed and feed 2. 50% improvement in tool lifetime Ⅱ Hole Processing (Drilling, Boring and etc.) Low Pressure Cutting Fluid / Flood Coolant Cutting fluid cannot reach a processing point and almost not cutting fluid is supplied to the tool. Peck cycle is used because chip discharge is difficult. Re-cutting often occurs because thread like chip surrounds the tool and tool holder. High Pressure Cutting Fluid / Through Tool Coolant Ⅲ Turning High Pressure Coolant Cutting fluid is supplied to a processing point at the highest pressure. Chip is discharged effectively from a deep hole by reflected pressure and cutting fluid. The drill can perform more difficult processing therefore reducing work hour. The tool s lifetime is significantly increased compared with the use of low pressure cutting fluid. Highly reduced heat zone is created through the direct spray of cutting fluid to a processing point. Cutting hydraulic wedge effect can be produced depending on the usage. Wearing of the tool is reduced by cooling the contact zone between chip and tool. Cutting chip into small pieces increases chip discharging capability. This prevents re-cutting by chip and increases tool lifetime 05

16 BF-SERIES Ⅱ Bag Filter Type of High Pressure Coolant System For processing problem, chip blocking in automation process, etc. you can solve them by using high-pressure cutting oil now Low-pressure cutting oil (14kgf/ cm2 ) is not able to pass through cutting heat curtain that take place from high-speed rotation processing being evaporated before reaching cutting area, which may not serve its proper function as cutting oil. Especially for CNC lathe and automatic lathe requiring high-precision, processing of the materials difficult to cut, complex processing, high-speed processing for muilti-product, it is necessary to use high-pressure cutting oil now Improvement in chip-treatment capacity High pressure cutting oil system enables smooth chip treatment incomplex processing of the materials difficult to cut and automation process.

22 2016 켐텍카다록 영문_레이아웃 오전 9:48 페이지 22 OIL SEPARATOR The oil separator provided by Profluid can solve all problems caused by tramp oil/tramp solid. Ⅰ The Effect of Tramp Oil 1. Degradation of machine and tool functions and shortening of tool life (clogging of various filters & nozzles) 2. Foul odor and skin disease to workers caused by the formation of various kinds of bacteria 3. Product failure be caused by decomposition and rust occurrence 4. The acceleration of industrial waste production increases environmental costs Ⅱ Principle of Removing Tramp Oil The existing method to separate tramp oil by smearing it on the belt or hose has a problem with efficiency and waste oil handling because a large amount of cutting fluid is mixed and separated. Using the fact that specific gravity varies for different liquids to be separated such as water and oil, Profluid Øs oil separator uses a principle of the fast speed separation between water and oil through physical dislocation when mixed liquid passes through the filter (media with a large number of pores). 1. The tramp oil along with the cutting fluid is inhaled into the tank using the built-in pump 2. The cutting fluid inhaled along with the tramp oil passes through the porous filter layer. While the tramp oil passes through the filter that has a large effective specific surface area as line structure without forming inclined surface, particles of the tramp oil are enlarged by speed difference caused by viscous flow and the oil rises to the surface 3. The floated tramp oil is separated and discharged using specific gravity difference between water and oil 22

24 CHILLER UNIT Ⅰ Description of Cooling Cycle Dryer Expansion Valve Inhalation Condenser (Fluid) Discharging Outlet High Pressure S/W Liquid Temperature Detection Sensor Inhalation Inlet Evaporator (Refrigerant) Gas Temperature Detection Sensor Chiller Control Console Refrigeration cycle Compressor Condenser Expansion Valve Evaporator It is divided into compression process, condensation process, expansion process and evaporation process. Compressor, condenser, expansion valve and evaporator exist at each process It increases pressure by compressing refrigerant vapor to allow the refrigerant vapor (low temperature, low pressure, gas) to evaporate from the evaporator for it to easily condense. The refrigerant cycles inside the cooling device, through repeated evaporation and condensation processes, delivers heat from low temperature to high temperature. It is a heat exchanger that cools and liquefies refrigerant vapor (high temperature, high pressure, gas) that obtains cycling power from the compressor. High temperature refrigerant exchanges heat with air through the fan and refrigerant with high temperature, high pressure and gaseous state is condensed to medium temperature and high pressure liquid state by passing through the condenser. It controls refrigerant fluid flow during cooling cycle and lowers pressure and temperature to facilitate heat absorbing process through fluid evaporation by supplying refrigerant fluid to the evaporator. At the same time, it controls and supplies the adequate refrigerant fluid flow by responding to a change in refrigeration load. As a heat exchanger that performs cooling process at the cooling device, it is a device that makes low temperature and low pressure refrigerant fluid supplied to the evaporator exchange heat with cooling target material (oil, water or cutting fluid). Refrigerant fluid required in cooling is supplied through the expansion valve and evaporated vapor is supplied to the compressor. Through the repetition of this cycle, the fluid inhaled to the chiller and discharged is maintained and managed at a temperature that a user desires. 24
