HWR

What is HWR?

HWR is a German company specialized in mechanical engineering, developing and manufacturing clamping solutions for the demands of CNC machining. The company’s official name is HWR Spanntechnik GmbH, and it was founded in 1989. HWR focuses especially on the precise, repeatable, and flexible clamping of workpieces during machining, where high dimensional accuracy, short setup times, and maximum process reliability are essential. The company’s solutions are designed for machine shops and manufacturing plants producing single pieces, small batches, or automated series production.

HWR as a Developer of Clamping Solutions for Machine Shops

At the core of HWR’s operations is the optimization of clamping during machining. Clamping solutions directly impact machining accuracy, surface finish, cutting parameters, and machine utilization. HWR develops its products based on real-world machining needs, taking into account the unique requirements of both turning and milling. Their solutions are suitable for a wide range of machinable materials, such as steels, aluminum, and cast iron, and can be used in both horizontal and vertical machining centers.

HWR and Modular Clamping Technology

HWR is especially known for its modular approach, where clamping systems can be quickly adapted to different workpieces. Modularity is a key advantage in modern CNC machining, where batch sizes vary and flexibility is essential. HWR’s solutions utilize features such as zero-point clamping, compensating jaw constructions, and low-profile clamps that allow access to multiple surfaces of the workpiece in one setup. This minimizes the need for reclamping and improves the repeatability of dimensional accuracy.

HWR Products for Process Reliability in Machining

HWR’s clamping solutions are designed to withstand the forces and vibrations generated during machining. Stable clamping enables consistent cutting conditions, which extends tool life and reduces wear. The clamping solutions are suitable for both manual and automated production, where pallet systems and robotic handling place additional requirements on clamping technology. HWR’s solutions help machine shops improve throughput and production predictability.

HWR in the International Mechanical Engineering Industry

HWR operates internationally, and its products are widely used in European mechanical engineering and globally. The company’s solutions have also gained traction in Finnish machine shops, where reliable quality, easy implementation, and durable clamping solutions are valued. HWR’s position is based on long-term product development and a focus on solutions designed for real-world machining—not just in theory.

Summary

HWR is an established manufacturer of clamping solutions for the mechanical engineering industry, with products that support precise, efficient, and flexible CNC machining. The company’s solutions help machine shops improve process reliability, reduce setup times, and maximize the effective use of machining capacity. HWR’s clamping technology is an essential part of modern machining, where accuracy and repeatability are critical requirements.
