Smaller-Footprint Filtration Systems Increase Efficiency
IMTS 2018: Vomat filtration systems, displayed and distributed by Oelheld, provide compact, energy-efficient solutions for the metal processing industry.
Vomat filtration systems, displayed and distributed by Oelheld, provide compact, energy-efficient solutions for the metal processing industry. The filtration systems are ideal for filtering oils and removing the ultra-fine particles that result from grinding, honing, lapping, eroding and other metalworking processes.
The automatically-controlled filter backwash process is activated on demand and separates contaminated oil from clean oil. Energy consumption is decreased through a combination of frequency-controlled filter pumps and on-demand filtration. High-performance, pre-coat filters ensure that clean oil meeting the purity class of NAS 7 (3-5 μm) is available for long periods of time. The filtration systems are low-maintenance, compact and range in available sizes from standalone units for single machines to plant-wide central systems. Their customizable modular concept has multiple cooling and disposal options and can handle mixed use of carbide and HSS.
Systems on display include the compact, standalone FA series, which ranges from 70 to 1,200 L/min flow rate, and the UBF vacuum belt filter. The belt filter has a filtration fineness ranging from 3 to 25 μm and is suited for filtering oils and emulsions contaminated with steel, HSS, binders and grinding wheel particles.
Precision Tool Technologies found capacity for diversification not by adding machines, people or space, but by freeing up time. Running unattended—running so it can machine through all 168 hours in the week—has enabled this shop to use hours when staff is present to deliver work that lands outside its established specialty. To achieve unattended machining, some of the biggest challenges have related to basic details such as chips and coolant.
Systems designed to put out fires inside machine tools can provide a level of protection that external systems such as overhead sprinklers cannot. They cost a small percentage of the investment represented by today’s CNC machines and certainly far less than repairing major damage caused by a fire.
Bacterial growth in metalworking fluids eventually leads to machine downtime. Furthermore, shop owners and plant managers see an increased cost of purchasing replacement fluids and the disposal of spent fluids.
