About 85z18 collet

Types of 85Z18 collets

Collet is a workpiece holder that is commonly used in the milling and lathe machine to hold workpieces of various shapes and sizes. The 85Z18 collet is one of the types of collets that businesses can order.

  • Universal collets:

    Universal collet is a small, cylindrical sleeve that is used to hold or grasp a workpiece with the help of a machine tool. It is available in multiple sizes to provide support for different diameter ranges. Generally, universal collets are used for round workpieces. However, there are types of universal collets that also can hold non-round or hexagonal shapes, such as square collets.

  • Taper collets:

    Taper collets have a tapered shape. Due to the tapered geometry, they can grasp workpieces with different diameters firmly. In particular, taper collets are commonly used to hold workpieces with small diameters, such as drill bits. They have some advantages, such as high accuracy, ease of use, and adaptability, which make them extremely suitable for workpiece-holding and assembly functions.

  • Flex collets:

    Flex collets are a single or multiple split collet design. The flexible collets can hold the workpieces that have an eccentric shape, such as an octagonal or triangular shape. In addition, they can absorb misalignment and provide a repeatable concentric grip.

Specification & maintenance of 85z18 collets

80z18 collets have the following specifications:

  • Typically made from durable materials such as high-carbon steel, tool steel, alloy steel, or spring steel.
  • Heat-treated and tempered to achieve a specific hardness and durability, often between HRC 40 to 50, to provide a firm yet flexible grip around the cutting tools.
  • Surface finishes may include black oxide, chrome plating, zinc coating, or nitrocarburizing, which increase the resistance to corrosion and wear.
  • The diameter range of 85z18 collets can be from 0.5 mm to 5.5 mm, but collets of different sizes hold cutting tools of various diameters.
  • Collets can typically withstand a load capacity of 8-20 Nm because they provide sufficient frictional torque to prevent the cutting tools from slipping during operation.
  • Some collets are compatible with electrical and hydraulic spindle systems.
  • The working temperature range of collets is from -20 °C to 120 °C, but it can be higher if the collet material is different.

Generally, 85z18 collets are low-maintenance accessories. However, they still require some care and attention to keep them in good working condition and ensure their longevity and optimal performance.

To maintain these collets, please do the following:

  • Clean the collet frequently to eliminate the dust, debris, and residue of cutting material. Cleaning will prevent the collet from jamming and its normal closure for a long time.
  • Apply a small amount of lubricant to the collet periodically to keep it well-functioning.
  • A lubricant can protect the collet from rust, lubricate its operating part, and reduce friction.
  • Prevent liquid lubricant from getting into the collet cavity. If it does, clean it with a paper towel or lint-free cloth as soon as possible.
  • Avoid over-lubricating the collet because it will allow the lube to get into the tools and cause them to slip inside the collet.
  • Lubricate the chuck instead of the collet if the tool has a chuck. Unlike a collet, a chuck uses bearings, and the lubricant for its bearings helps the chuck function properly.
  • Collets with threads or grooves should be cleaned and lubricated so that dirt does not accumulate in these areas.
  • Use only the recommended cleaning agent for the collet because not every cleaner is suitable for a specific collet material.
  • Use a brush with stiff bristles to clean the collet.
  • Store the collet in a protective case or drawer when it is not being used to keep it dry and safe from damage.

Applications of the 85z18 collet

85z collets are useful in several industrial applications. Some of which include the following:

  • Machining metals: The 85z18 collet is widely used in CNC lathes and milling machines. These machines are mainly used for metalworking tasks. 85z18 collets serve as workholding devices. They grip and support metal workpieces or machinist tools with great precision. Additionally, collets can accommodate tools with varied shank sizes due to their flexible design.
  • Routing and woodworking: In woodworking and metalworking businesses, routers are standard tools used to hollow out areas of solid materials. These routers often use 85z18 collets to hold their cutting bits tightly and accurately. The collet enables the router bit to be mounted at the right shaft, achieving the desired precision when making complex cuts.
  • Spindle toolholding: The 85z18 collet serves as an essential part of spindles. It holds machining tools like drills, end mills, and taps during the process of eroding. Additionally, it aids the smooth operation of equipment like grinders and lathes. With the application of this device, machining businesses are able to achieve high levels of precision and stability when working with different types of materials.
  • Automotive and motorcycle industries: The 85z18 collet plays a key role in automotive and motorcycle assembly lines, as well as in the aftermarket. It is commonly used for welding machines and air compressors that are equipped with an 85z18 collet adapter. In automotive applications, the collet is highly useful for holding spark plug threads during spark plug insertion and removal.
  • Prototyping and robotics: Robotics and CNC machining are two modern technologies that have been widely applied in the automotive industry. The automotive industry машин ашиглах, which requires a high level of accuracy and automation. The collet is used as a crucial component in the grip system of robotic arms. They precisely hold and position automotive parts during the machining process. Additionally, automotive robotics rely on the accuracy and repeatability of CNC machines to function properly. The CNC machines depend on the collets to ensure accurate tool changes and seamless automation.

How to Choose 85z18 collets

Business buyers should consider various factors before purchasing 85z18 collets for themselves or their end users.

  • Machinery Compatibility

    Ensure the collet fits particular machining tools. Collet compatibility with machines guarantees simple fittings, efficient functioning, and a smooth machining process without interruptions.

  • Quality Material

    The material used to manufacture the 85z18 collet affects its sturdiness and lifespan. Select collets made from solid materials like spring steel or carbon steel. Such materials offer high-performance holding capability and resilience under regular usage.

  • Operating Tolerance

    Choose collets that can withstand high levels of intention and pressure. As a result, the equipment will work well, producing precise and excellent output. A collet with a high working tolerance protects both itself and the machining equipment.

  • Range of Workpieces

    Depending on the type of workpiece, select the 85z18 collet that can hold particular workpieces. Collets are available in different types to cater to various workpieces. For example, an 85z18 rubber collet holds irregular shapes, while a standard one grips cylindrical workpieces.

  • Desired Grip Strength

    Select the collet that provides the desired holding strength for the workpieces. Different collets offer various clamping forces. For instance, air collets apply more force than standard ones. Choose air collets if higher gripping strength is needed.
