1. The difference between the shape card slot and the matching use is that the ER cylinder clamp is used with the ER tool handle nut, and the SK cylinder clamp is used with the SK tool handle nut. 2. Differences in models, specifications, dimensions, and clamping ranges. The ER series cylinder clamps are divided into eight models: ER8, ER11, ER16, ER20, ER25, ER32, ER40, and ER50. The SK cylinder clamps are divided into five models: SK06A/AA, SK10A/AA, SK16A/AA, SK20A/AA, and SK25A/AA. 3. The...
In 1972, the Swiss cutting tool company invented the ER clamping system, which changed the cutting tool clamping industry. And it became a DIN standard (JIS B 6339) in 1993. Today, ER spring collets are widely used in various clamping systems. But with the development of the times, high-speed machining technology has undergone rapid development. In high-speed machining, the high-speed rotation and accuracy requirements of the cutting tools are very high. Therefore, with the development of the...
After the CNC tool handle rusts, it will have a negative impact on machining accuracy and efficiency, and may even cause damage to the spindle equipment. The specific manifestations are as follows: Reduced machining accuracy: Rust on the conical surface of the CNC tool handle can affect the fixation and rotation of the tool, leading to a decrease in machining accuracy. Shortened tool life: Rust on the conical surface of the CNC tool handle can reduce tool accuracy, thereby shortening the tool's...
The ER spring collet chuck are mainly used for clamping with straight shank cutters such as dry drills, milling cutters, and taps. The elastic deformation of the clip is 1mm, and the clamping range is 0.5-32mm in diameter. Nowadays, CNC machine tools are widely used in factories, and these machines and tools come from all over the world, with different models and standards.
1) To ensure machining accuracy, use machine tool fixtures to clamp the workpiece, which can accurately determine the relative position relationship between the workpiece, tool, and machine tool, It can ensure machining accuracy. (2) Improving production efficiency: Machine tools and fixtures can quickly position and clamp workpieces, reducing auxiliary time and improving production efficiency. 3) The use of mechanical, pneumatic, and hydraulic clamping devices in machine tool fixtures can...
When using a vertical milling machine to process some long rectangular stencils, it is not difficult to machine the flat sheets with a disc milling cutter, but it is more difficult to machine the two ends of the stencil. If the stencil is processed vertically, a verticality is not easy to guarantee. It may be that the template is too long to be erected, so that the milling cutter needs to be removed first and then replaced with an end mill. Frequent tool changes like this are common for mold...
In actual production, it often encounters drilling 0.5 ~ 4mm small holes, because the drill bit diameter is thin, the strength is low, often due to excessive or uneven force during the feeding, the workpiece material organization is uneven The vibration of the drill spindle and the poor chip evacuation caused the bit torque to increase, which caused the drill bit to break, and the removal of the drill bit was more troublesome. For this reason, we designed a safe drilling small hole chuck.

The live center, which can be used for drilling, threading and reaming of workpieces, is a machine tool component in machining, and has two types: fixed center and movable center. The lathe center is used for centering and bearing the gravity and cutting force of the workpiece. The lathe center can be directly installed in the taper hole of the lathe spindle, and the front tip rotates with the workpiece without relative movement, so quenching is not necessary. The moving center is equipped with...
1. The circlip must always be inserted in the ER nut, 2. Before putting the tool into the circlip, the nut must be screwed on the tool holder. 3. Install the circlip into the nut by applying light pressure on the collet body, and apply radial pressure on the collet sleeve when loosening. 4. Never lock the nut when the tool is not put in. 5. When the rigidity is sufficient, use ER toolholder with small specifications as much as possible to make the tool obtain greater selling force.

1. Requirements for the tool CNC lathes can double as coarse and fine turning. In order to make the rough car can eat big knife and big knife, the rough car tool is required to have high strength and good durability; the fine car first guarantees the machining precision, so the tool requires high precision and good durability. In order to reduce the tool change time and facilitate the tool setting, the machine clamp should be used as much as possible. Use the machine clamp to prepare conditions...
CNC machining centers have continued to improve and develop over the past 30 years. The design of these machines is now fully flexible and can be applied to a variety of processing applications from short-term tool manufacturing to long-term product production with minimal structural changes. In the past, aircraft components that had been assembled by welding or riveting can now be machined from hollow aluminum blocks in high-speed, high-power machining centers. Automotive engines used to be...
The application of numerical control technology and CNC machine tools has successfully solved some automation problems of small-to-medium-sized parts with complex shapes and high consistency. This not only greatly increases production efficiency and processing accuracy, but also reduces the labor intensity of workers. Shortened the production preparation cycle. However, during the use of CNC lathes, CNC lathes will inevitably cause various failures, so the maintenance of faults has become the...
During the use of the spring chuck, if it is used with high accuracy, it will generally bore a tool first, so the accuracy of the chuck is the spindle accuracy. For the spring collet after front end quenching, as long as the use is reasonable, the life factor is not considered at all. Jade The precision of the meter tooth type and special-shaped spring collet is determined by the manufacturing precision of the collet. The spring chuck is a simple technological device, but there are many main...
Introduction: The three-jaw chuck is composed of a chuck body, an active jaw and a jaw drive mechanism. The movement of the three movable jaws on the chuck serves to clamp and position the workpiece. The three-jaw chuck is one of the commonly used hydraulic accessories for lathes, but it often occurs after a period of use that the workpiece is not easily mounted. On the one hand, the jaws of the three-jaw chuck are unevenly worn in front of one another, and on the other hand, Due to improper...
The improved lathe chuck wrench (see figure) is composed of a handle 1, a bush 2, a spring 3, a sleeve 4 and a body 5. The sleeve 4 and the wrench body 5 are in a clearance fit, and the sleeve 2 and the sleeve 4 are in an interference fit and are in clearance fit with the wrench body 5. The purpose of the bushing is to prevent the sleeve from falling out. Usually, the square head on the wrench body is made by the spring force.
1 Introduction With the increasing demand for work efficiency, hydraulic chucks have gradually replaced manual chucks and have been widely used. In order to meet the processing requirements of different workpieces, such as rectangular surface, cylindrical surface and other irregular surface parts of the workpiece, and some clamping surface and the workpiece surface eccentricity of the workpiece, usually requires the use of four-jaw hydraulic chuck. Looking at the four-jaw hydraulic chuck...
1.Press the locking tabs on the side of the battery with your fingers and pull the battery out of the Hitachi cordless drill. The battery is below the handle on your drill. 2.Hold the ring with one hand and turn the chuck sleeve counterclockwise with your other hand to open the chuck fully. The ring is the portion next to the turning sleeve on the chuck. 3.Look inside the center of the chuck and locate the Phillips-head screw that secures the chuck to the spindle.

A drill is a must-have item for any home owner or construction professional. Drills are available in a variety of sizes and weights, and are run on a battery or an electrical cord. Older drills required the use of a special key, called a chuck, to change out the drill bit. Most newer models of drills are called keyless chuck drills and do not require this specialized key. Keyless chuck drills make jobs much faster and enable you to change out drill bits rapidly. 1.Hold the keyless chuck drill...
