The client selected the KEMROC KDS 20 diamond saw<\/strong><\/a>, equipped with a concrete blade (800 mm diameter),<\/strong> and mounted it on a BROKK 180E<\/strong> machine with an extendable arm<\/strong>, an ideal setup for operating within narrow tunnel profiles.<\/p>\n\n\n\n The project spanned a duration of 2 months<\/strong>, requiring cutting a total of 400 meters<\/strong> along the vertical tunnel walls. The target cutting depth varied between 10 and 15 cm, with an expected production rate of approximately 40 linear meters per day<\/strong>, adjusted for non-continuous operation cycles dictated by site logistics.<\/p>\n\n\n\n Tunnel environments present significant operational limitations: Faced with these challenges, the project team evaluated multiple cutting options. The KEMROC KDS 20<\/strong> was chosen for its: High productivity in confined spaces<\/strong>, ability to achieve precise, clean vertical cuts<\/strong>, minimal vibration and noise compared to impact tools, proven performance on BROKK electric demolition robots<\/strong>, which offer superior maneuverability in tunnels, and efficient blade consumption, only 1 diamond disc<\/strong> was used over the entire 400-meter scope.<\/p>\n\n\n\n Once mounted, KEMROC Diamond Saw KDS 20<\/strong> delivered excellent results: Productivity averaged 40 linear meters per day<\/strong>, aligned with the project\u2019s targets, a testament to the reliability of the KDS Diamond Saw as a smart solution under continuous use.<\/p>\n\n\n\n <\/p>\n\n\n\n The project team reported high satisfaction with the KEMROC KDS solution: “The KDS 20 proved to be an excellent choice. We completed all vertical cuts as specified, with minimal blade consumption and without the vibration issues associated with conventional cutting methods. The setup with BROKK 180E was ideal for our confined work area.”<\/p>\n\n\n\n <\/p>\n\n\n\n KEMROC\u2019s KDS Diamond Saw<\/strong><\/a> once again demonstrated its value in a critical infrastructure application, enabling safe, precise, low vibration, and efficient cutting in a challenging SNCF tunnel<\/strong> environment.<\/p>\n\n\n\n The success of this project reinforces KEMROC\u2019s position as a trusted partner for smart cutting solutions in railway, tunnelling<\/a>, demolition<\/a>, and civil engineering<\/strong> sectors across Europe.<\/p>\n\n\n\n KEMROC KDS Diamond Saw Powers Tunnel Cutting in SNCF Project, France BROKK 180E with KEMROC KDS 20 | Vertical Cuts in Limestone Rubble and Concrete In a recent SNCF (French National Railway) tunnel project in France, ALSACIENNE DE MINAGE ET DEMOLITION were tasked with executing precision cutting in a confined and challenging underground environment.

<\/figure>\n\n\n\nTunnel Cutting<\/strong> Application Challenges<\/strong><\/h4>\n\n\n\n
1. Space constraints limited the use of larger hydraulic equipment.
2. Dust suppression and cooling were critical; water supply was available onsite to enable wet cutting<\/strong>
3. The site required vertical cuts<\/strong>, demanding high stability and precise control.
4. In addition, the material composition, a mix of concrete<\/strong> with embedded limestone rubble<\/strong>, presented a variable cutting profile, placing additional demands on tool performance and wear resistance.<\/p>\n\n\n\nWhy KEMROC KDS Diamond Saw?<\/strong><\/h4>\n\n\n\n

<\/figure>\n\n\n\nPerformance on Site<\/strong><\/h4>\n\n\n\n
1. The Tunnel cutting process was stable and smooth, with operators able to maintain consistent depth and line<\/strong> across all wall sections.
2. The BROKK 180E<\/strong>\u2019s extendable arm provided the reach and positioning flexibility required for vertical cutting along the tunnel walls.
3. Water cooling effectively managed dust and blade temperature, ensuring safe and efficient operation.<\/p>\n\n\n\nResults & Customer Feedback<\/strong><\/h4>\n\n\n\n
