Indexing table machines – find manufacturers and suppliers

Indexing table machines in the machine tool sector are special production systems that automatically position and transport mechanical workpieces or components and prepare them for processing steps such as milling, drilling, turning or grinding.

They are among the central automation components in modern production lines and enable efficient and precise processing of large quantities.

Below you will find the functionality and types of indexing table machines, as well as a brief overview of their areas of application and their advantages:

How indexing table machines work:

The core of an indexing plate machine is the indexing plate, a rotating or stepping disk that picks up workpieces and positions them precisely for subsequent processing stations.

1. Indexing:
   The indexing table moves in defined steps (index steps) so that each processing station can reach the workpieces precisely and with repeat accuracy.
2. Clamping:
   The workpieces are fixed in place using clamping devices, grippers or magnets to ensure that they remain stable and secure during processing.
3. Synchronization:
   Sensors and control systems ensure that each position of the plate is precisely synchronized with the machining cycles of the machine tools, avoiding process interruptions and collisions.
4. Integration:
   The indexing table can be operated as a stand-alone machine or as part of a manufacturing system with multiple machine tools.

Types of indexing table machines:

Indexing table machines can be differentiated according to the type of movement, design and area of application:

1. Horizontal indexing tables:
   The workpieces are transported on a horizontal plane; ideal for turning or milling on the side surface of workpieces.
2. Vertical indexing tables:
   The workpieces are clamped vertically, which saves space and is advantageous for certain machining operations, e.g. drilling holes from above.
3. Indexable or stepping indexing plates:
   The plate moves in precise steps, giving each station sufficient time for processing.
4. Continuously rotating plates:
   Suitable for high-speed production where machining and transportation take place simultaneously.
5. Plates with tool magazine or gripper device:
   For workpieces of different sizes, shapes or materials that need to be processed flexibly.

Use of indexing plate machines:

Indexing table machines are widely used in the automotive industry, mechanical engineering, aviation and precision engineering:

1. Milling and drilling:
Automatic positioning of workpieces for multiple machining.

2. Turning and grinding:
Centralized fixing and rotation for uniform machining.

3. Assembly processes:
Workpieces are prepared for assembly or transferred to downstream stations.

4. Mass production of series components:
High quantities can be processed efficiently and precisely.

5. Integration into production lines:
Combination with robot cells, machine tools and testing systems for end-to-end automation.

Advantages of indexing table machines:

The use of indexing table machines in the machine tool industry offers several advantages:

• Precise positioning of workpieces for repeatable machining.
• Simultaneous processing of several workpieces and shorter cycle times.
• Adaptable for different workpiece sizes, shapes and materials.
• Workpieces are held securely in place, minimizing damage.
• Integration with robotics, tool magazines and control systems enables almost fully automated production processes.
• Compact design compared to linear conveyor systems or several individual machines.
• Synchronized processing and transport prevent waiting times between stations.

Indexing table machines for machine tools are key components of modern production systems that enable precision, efficiency and flexibility in series production. They are not only used for the exact positioning of workpieces, but also for optimizing production processes and reducing cycle times. Thanks to their adaptability to different workpieces and processing steps, they are indispensable in numerous industries, from automotive and mechanical engineering to precision manufacturing and aviation.

Below you will find an overview of the most important criteria to look out for when purchasing indexing table machines:

A structured approach is crucial when purchasing indexing table machines for the manufacturing industry, as these machines have high investment costs, complex technology and long life cycles. The selection directly influences the production capacity, precision and cost-effectiveness of the manufacturing processes.
First of all, the machine must be precisely matched to the manufacturing process and the workpieces:

• Indexing tables must be able to accommodate different workpiece dimensions and geometries.
• Steel, aluminum, plastics or sensitive materials require different clamping and handling solutions.
• Determine how many processing steps or test systems the plate has to handle simultaneously.
• The turning or indexing speed depends on the cycle time, the machining duration and the desired throughput.
• The indexing table must be able to safely support and transport the weight of all workpieces.
• High positioning accuracy is essential for precise machining and assembly.
• The design determines the flexibility and robustness of the machine:
• Horizontal vs. vertical design: depending on the available space and type of machining.
• Indexed or continuous movement: Step-by-step movement for precise machining, continuous movement for high throughput.
• Drive type: Servomotors, electric motors or pneumatic systems influence accuracy, speed and maintenance requirements.
• The clamping and fixing systems should be as flexible and robust as possible and suitable for different workpieces.
• Position and end position sensors for controlling and monitoring production processes are also important.
• Indexing table machines are often integrated into complex production lines. You should therefore bear this in mind when purchasing:
• Interfaces for synchronization with milling machines, drills or robots.
• Control systems such as PLC, CNC or Industry 4.0-compatible solutions facilitate monitoring and process control.
• Gripper systems for feeding or removing workpieces.
• Option to integrate additional processing stations or test modules at a later date.
• The machine must comply with occupational and industrial safety standards:
• Machinery Directive and CE marking as legal conformity for operation in Europe.
• Protective devices such as covers, emergency stop switches, interlocks to protect operating personnel.
• Operation and maintenance must be carried out without risk.
• Depending on the industry, ISO, VDI or industry-specific standards for precision and safety.
• In addition to the purchase price, long-term costs also play a role:
• Life cycle costs: energy consumption, maintenance costs, wearing parts and ease of repair.
• Availability of spare parts: Short delivery times reduce production downtime.
• Manufacturer reliability: Long-term support, service contracts and technical support ensure operation.
• Flexibility and service life: Adaptability to future workpieces or production changes increases profitability.
• An experienced supplier is crucial for successful investments:
• Proven experience in shifting plate machines and production lines.
• Technical support, training for operators and maintenance personnel.
• Proof of supplier quality management through ISO or industry-specific certifications.

The purchase of indexing table machines requires a comprehensive analysis of technical, economic and safety-related criteria. The machine must be precisely matched to the workpieces, processing steps and production environment, while at the same time being flexible, durable and easy to maintain. An experienced supplier with comprehensive service and a reliable supply of spare parts is crucial to ensure efficient, precise and economical long-term production operations.
