Rotary table 100 mm

Types of rotary tables

A rotary table is a flexible work-holding component that allows for the rotation of items around a vertical or horizontal axis. There are two types of rotary tables: manual and CNC. Both types are available in different sizes and shapes to suit any requirement.

• Manual rotary tables:

  Manual rotary tables are tables that operators adjust manually to position the workpiece while doing machining operations. In this kind of rotary table, the machinist uses a hand crank to turn the worktable and expose other parts of the workpiece to cutters or other tools. Manual rotary tables are uncomplicated and cost-effective but require the operator to stop working to reposition the workpiece. Hand crank rotary tables are usually made with precise degree markings on the table so the operator can know how many degrees the table has turned for each turn of the crank.

• CNC rotary tables:

  A CNC (computer numerical control) rotary table is a worktable fitted with an electrical motor that allows it to move automatically to position a workpiece during a machining operation. CNC rotary tables offer more accurate and efficient machining than manual tables and reduce the need for the operator to be present. An integral part of a CNC rotary table is a control program that tells the motor how far to turn the workpiece, and the degree of precision this allows is much greater than that achievable with a manual rotary table.

  CNC rotary tables are usually very large and heavy and made of more massive metal parts than manual tables to cope with the increased precision and the workpieces' weights. CNC rotary tables are also more expensive than manual tables, and the operator must be more complicated and have advanced skills.

Specifications and Maintenance of Rotary Table 100 mm

The specifications of a rotary table vary between models and types. Details such as the size, compatibility with different machines, and weight capacity are vital to consider when purchasing a rotary table.

• Sizes

  A rotary table with a table diameter of 100 mm is small and ideal for short vertical and horizontal workpieces. When coupled with a dividing head, it also helps to carry out projects that involve intricate circular cuts. However, larger diameter rotary tables like 300 mm can be used to support large diameter cylinders and discs.

• Compatible Machines

  The rotary table to choose will also depend on which machine it will be paired with. For instance, if a bench top drill is being used, an at- home rotary table would be a better fit than an industrial scale one.

• Weight Capacity

  All rotary tables have their work-holding capacities denoted. This capacity denotes the maximum weight the rotary table can support while rotating accurately. Small rotary tables generally support workpieces with a weight of up to 100 kg. Larger ones have higher capacities.

Maintenance

The simplest way to increase the longevity of a rotary table is to practice regular maintenance. This involves routine testing and monitoring of the table to see if any parts need repairs or replacements.

For its smooth operation over the years, cleaning it regularly should become a priority. Debris and dust build-up can severely hinder the performance of the table. Even a small amount of debris can cause it to jam or slow down temporarily. Regular cleaning ensures that no build-up occurs.

Lubrication is also vital to keeping a rotary table in a working condition for years to come. It minimizes any wear and tear from friction and keeps the functioning smooth and seamless.

While the above maintenance tips go a long way in enhancing a rotary table's longevity, it is always best to check with the manufacturer's manual for any specific requirements. Each table may call for distinct maintenance practices that should not be overlooked.

Application Scenarios of Rotary Table 100 mm

The 100 mm rotary table is an extremely versatile machine tool accessory used in various scenarios across metalworking and machining industries. Here are some of the most common application scenarios where the rotary tables are used.

• Drilling and punching holes in workpieces: One of the most common uses of a rotary table is to drill or punch holes in a workpiece at even intervals. The workpiece can be clamped horizontally or vertically to the rotary table. Next, the drill press is raised, lowered, and adjusted to drill holes through the workpiece. The rotary table can then be rotated 90 degrees or 180 degrees to drill the next set of holes, creating a workpiece with evenly distributed holes.
• Creating keyways andslots on workpieces: The rotary table can be used together with a standard milling machine to create keyways and slots on various workpieces. To do this, the workpiece is clamped to the rotary table, and then the table is rotated manually or indexed to the desired cutting position. Afterward, the milling cutter is then set to cut the keyway at the appropriate depth and width. Finally, the rotary table is rotated to the next cutting position and then repeated as necessary.
• To create gearsshapes andcontours: Rotary tables can also be used to create gears, complex shapes, and contours on workpieces. Generally, the workpiece is first secured to the table of the rotary machine. Next, the cutting tool is then set up and programmed to make the desired cuts. The rotary table is then indexed or rotated, so the workpiece is in the appropriate position for each cut. With this method, Machinists can easily create contoured profiles on irregularly shaped workpieces.
• Drilling and Reaming Circular Workpiece: A rotary table can also be used to simplify circular drilling and reaming operations. The workpiece is clamped to the rotary table with faceplates or T-slots. Afterward, the drill or reamer is then fed vertically or horizontally to make the required holes in the workpiece. Finally, the rotary table is rotated to the next position so that another hole can be made. The technique is quite simple and can be used by all skill levels.

How to choose Rotary Table 100 mm

With the demand for rotary tables increasing in the machinery market, it has become crucial to understand how to choose the proper machinery.

One should take into account the following factors:

• Heavy-duty design: A rotary table with a heavy-duty design is crucial for good stability during operation when dealing with large workpieces and high levels of cutting forces. It's important to have stable support from the equipment's weight distribution evenly throughout its base.
• Precision Bearings: The use of precision bearings in a rotary table significantly contributes to its smooth and accurate rotation. These high-quality bearings reduce friction, ensuring that the table turns effortlessly and maintains precision throughout the machining process. Invest in a rotary table equipped with precision bearings to enjoy worry-free use and dependable performance.
• Direct Drive System: Consider Direct Drive System. For improved efficiency and minimal maintenance requirements, consider choosing a rotary table with a direct drive mechanism over those with traditional belt or gear-driven systems. The absence of complex transmission systems simplifies maintenance and reduces the amount of time needed to care for the equipment.
• Workpiece Weight Capacity: The weight rating of a rotary table refers to the maximum mass it can hold while rotating. It is vital to note that exceeding the specified weight limit may cause damage or widespread failure. Be careful to choose a table whose weight capacity corresponds with how much you'll use it.
• Table Coating: Workpiece protection is important. To protect workpieces from scratches and other forms of damage during machining, it's crucial to have a coating on the rotary table, such as plastic or rubber. This coating acts as a cushion, preventing direct contact between the table and the workpiece, thereby reducing the risk of unwanted blemishes and maintaining the integrity of the workpiece.
