ER Collant Sealing Collet Precision Sealed Collet Machine Tools ER cooling sealed collet
ER coolant steel sealed collets,The cost of using tools is reduced, and all general tools can be used. If the tool has no internal cooling water outlet, the collet can conduct high-pressure precise water injection through the outlet to cool the tool and remove the waste around the tool. (There will be dead angle, insufficient pressure and other problems with water spraying by common methods)
1. ER Sealed Collet Material: SUJ2; 42CrMo;
2. ER Sealed Collet Hardness: 46-50HRC;
3. Spring Collet The use of groove differences, to achieve the surrounding water, only the center of the water function;
4 can withstand water pressure 7Mpa;
5. ER Sealed Collet Non-standard hole can be customized;
6.20 slot design to increase the number of elastic groove, shrinkage of 0.5mm, clamping force increases to increase the sealing;
7. ER Sealed Collet Provide two kinds of appearance: light decoration or coating treatment;
8.Collet Type: ER11C, ER16C, ER20C, ER25C, ER32C, ER40C, ER50C
9.Collet appearance: light coating (anti-corrosion, abrasion resistance, cleanliness number, accuracy and stability, smooth surface, feel comfortable, look more beautiful)
10Collet accuracy: 0.005mm, 0.008mm
When ordering, please indicate the accuracy grade
● Cryogenic treatment
1, -185 ℃ super-long cryogenic treatment, so that nearly all the retained austenite into martensite;
2. precipitation of nano-carbide particles to increase the hardness and toughness;
3. Reduce the residual stress;
4. Significantly improve wear resistance.
ER cooling sealed collets are a type of collet used in machine tools that have a cooling system built into them. These collets are designed to provide a constant flow of coolant to the cutting tool during machining operations.
The sealed design of these collets ensures that the coolant remains contained within the collet, preventing any leakage or spillage. This is particularly important when working with fluids that may be hazardous or corrosive.
The cooling system in these collets typically consists of channels or passages through which the coolant flows. The coolant is typically supplied through a separate coolant supply line connected to the machine tool.
The coolant helps to dissipate heat generated during the machining process, which can help to extend tool life and improve machining performance. It also helps to flush away chips and debris from the cutting area, improving chip evacuation and reducing the risk of chip recutting.
ER cooling sealed collets are available in various sizes and configurations to accommodate different tool shank diameters. They are commonly used in applications such as milling, drilling, and turning, where effective cooling is essential for optimal machining performance.
