Tool-free cam clamping for modular workholding

norelem has introduced new cam screws with integrated clamping levers designed for tool-free clamping operations in assembly, laser processing and modular fixture applications. The new additions are intended to simplify workpiece handling, reduce setup times and support flexible workholding configurations in manufacturing environments requiring frequent workpiece changes.

Tool-free clamping for fast setup operations
The cam screw design enables operators to clamp and release workpieces directly through an integrated lever mechanism without using external tools such as torque wrenches or Allen keys. The system is intended for production environments where workpieces must be repositioned or exchanged at short intervals, including assembly stations, manual workstations, test fixtures and laser processing applications.

The integrated clamping lever also allows flexible handle positioning across a 360-degree range, enabling adjustments that help avoid interference contours within compact fixture layouts.

Multi-clamping configurations for modular manufacturing
According to norelem, the cam screws can support cost-efficient multi-clamping setups in modular manufacturing environments. The use of multiple cam screws with clamping levers enables simultaneous loading of several workpieces onto clamping pallets or fixture systems prior to machine processing. This approach can reduce machine setup times and improve handling efficiency for complex fixtures or grouped component assemblies.

The system is also suitable for fixture plates used in milling operations where rapid clamping and repositioning are required.

New variants for different clamping applications
norelem has expanded the product range with multiple versions designed for varying clamping requirements and workpiece materials. The new portfolio includes versions with hexagonal brass clamping nuts intended to provide secure clamping while reducing the risk of material surface damage. Additional versions incorporate clamping washers designed for securing raw blanks, cut-off sections, forged parts and cast components.

The available thread sizes range from M6 to M16, while the clamping force range varies from 1.2 kN to 2.8 kN depending on the selected configuration.

The product variants are intended to support different fixture geometries, load requirements and material handling applications within industrial production systems.

Applications in assembly and laser processing environments
The cam screw systems are primarily targeted at assembly and laser processing environments characterized by short production cycles and medium mechanical loads. Potential application areas include mounting fixtures, testing gauges, manual assembly stations and pre-assembly systems for component groups. The simplified clamping operation may also support ergonomic improvements in manual workstations by reducing tool handling requirements during repetitive setup operations.

Standardized components for modular engineering systems
The product expansion reflects broader demand for modular workholding and flexible fixture systems within manufacturing automation and lean production environments. Standardized clamping components are increasingly used to reduce fixture design complexity, simplify maintenance and accelerate machine changeovers across flexible production lines.

Additional Context: technical specifications and competitive benchmarking not included in the original announcement
In the modular clamping and workholding segment, manufacturers including Halder, AMF, Elesa+Ganter and Carr Lane Manufacturing offer comparable cam-operated clamping systems and quick-change fixture components for industrial assembly and machining applications. Key benchmarking parameters include clamping force, setup speed, ergonomic operation, fixture flexibility, material compatibility and resistance to mechanical wear.

Industrial workholding systems are increasingly designed to support modular production environments, shorter batch sizes and faster machine changeovers. Tool-free clamping technologies are becoming more common in assembly automation, laser processing and flexible manufacturing systems where reduced setup time and simplified operator handling are critical productivity factors.

The presented solution is differentiated primarily through the integration of tool-free lever-operated clamping, 360-degree handle positioning, compatibility with multi-clamping fixture systems and support for a broad range of workpiece geometries and industrial assembly applications.
