Why Coolant Matters In Cold Saw Cutting Quality

Cold saws are widely used in metalworking because they produce clean, accurate cuts with excellent repeatability. However, many cutting problems attributed to blades or machines can often be traced to a much simpler cause: coolant. Metalworking machinery supplier Dimakin sets out why coolant matters in cold saw cutting quality.

Although described as ‘cold cutting’, the process still generates considerable heat where the blade meets the workpiece. Without effective cooling and lubrication, heat builds up in both the blade and the material, reducing cutting accuracy, accelerating tool wear and affecting surface finish.

Unlike abrasive saws, cold saws use a toothed HSS or TCT blade to shear metal cleanly. Coolant plays a vital role by removing heat from the cutting zone while reducing friction between the blade teeth and the workpiece. The fluid helps maintain stable cutting conditions, particularly during long production runs or when machining difficult materials.

Effective coolant flow also improves surface finish by flushing swarf away from the cut, preventing chips from being recut and reducing burr formation. Lower friction means smoother cutting, less vibration and longer blade life, helping to reduce downtime and operating costs.

Coolant quality is equally important. Poor-quality or incorrectly mixed fluids provide inadequate lubrication and cooling, leading to increased blade wear, residue build-up and inconsistent cutting performance. Using a high-quality soluble cutting fluid at the correct concentration helps maintain reliable cutting conditions while protecting both the machine and the tooling.

Rather than being treated as a simple consumable, coolant should be regarded as an integral part of the cutting process. Correct coolant selection and maintenance deliver measurable improvements in cutting accuracy, surface finish, blade life and overall productivity.

Gentiger Brings Precision And Performance To Copper Alloys

Long-standing Prosaw customer Copper Alloys has once again chosen to strengthen its manufacturing capabilities with a significant investment in three new Gentiger GT-HS bandsaw machines, enhancing its production capacity after the company secured a major new contract for the supply of its exotic alloys.

With more than 20 years of partnership between the two companies, Copper Alloys turned to Prosaw to support the increased demand and precision requirements associated with cutting high-performance materials. To meet these needs, the company has ordered three Gentiger saws, offering round cutting capacities of 430, 615 and 850 mm. This new equipment will enable Copper Alloys to apply efficient cuts to a wide range of exotic metals used across advanced sectors such as aerospace, defence, and high-integrity industrial applications.

A key part of the workload involves topping and tailing large non-ferrous alloy billets, as well as conducting various pre- and post-forging cutting operations. To streamline this, Prosaw designed and manufactured a bespoke heavy-duty rotating infeed table, engineered specifically to allow faster, safer, and more ergonomic rotation of billets during cutting.

Once fully commissioned, the new equipment will deliver notable performance gains for Copper Alloys. Faster cutting speeds, greater machine efficiency, and extended blade life all contribute to reduced operating costs and improved overall productivity. Each machine also features integrated power-usage monitoring for every cut, an increasingly valuable data point as energy costs continue to rise across the manufacturing sector.

This latest investment reinforces Copper Alloys commitment to high-precision sawing machines and continuous improvement, ensuring they remain a trusted supplier of advanced alloys to industries where quality and reliability are paramount.More information www.prosaw.co.uk

Nova 1200 Bandsaw Suits Large-Scale Ring Cutting

A new Nova 1200 bandsaw from Saws UK has been installed in the north of England to support the production of large rings for the oil and gas industry. Now fully operational, the machine is processing high-performance materials including Hastelloy and Inconel, strengthening the region’s capability for heavy-duty cutting applications.

Specifically configured for large-diameter ring production, the Nova 1200 features an electrically powered table that provides a positive, controlled feed throughout the cutting cycle. The design ensures smooth material movement and delivers the accuracy and repeatability required when machining heavy sections, even as ring geometry changes during the cut.

Equipped with a 54 mm blade, the machine is designed for demanding large cross-section applications. Combined with precise feed control, it maintains stable cutting conditions during extended production runs, making it particularly well suited to high-nickel superalloys and other difficult-to-machine materials.

A rigid saw frame minimises vibration and keeps the blade on a true cutting path, helping to prevent blade wander when processing thick, dense sections. The result is improved cut quality, extended blade life and lower operating costs through reduced blade changes.

Operator safety is integral to the machine’s design. The cutting area is fully enclosed within a robust safety cage, while interlocked guards prevent operation unless all access points are secure. An integrated light-beam protection system immediately stops the machine if the protected zone is breached, maintaining a safe working environment without compromising productivity.

The Nova platform has been used in industrial cutting applications since 1994 and has built a strong reputation for processing aluminium alloys, high-tensile steels and nickel alloys. The latest installation expands large-ring cutting capacity in the North of England, providing a reliable, high-performance solution for manufacturers serving the demanding oil and gas sector.

A CHANGE OF MACHINE STYLE BRINGS BENEFITS TO COMBINED ENGINEERING SERVICES WITH INVESTMENT IN XYZ TMC

Combined Engineering Services (CES) was born following the 2018 merger of Brecon Designs (formed in 2007) with another local engineering company, Infinite Engineering Design. Since then, managing director Steve Willams and his team have seen continued growth.

From humble beginnings with a facility housing little more than a turret mill, manual lathe and wire eroder, CES now has substantial CNC machining capability. This allows the company to manufacture tooling, jigs and fixtures, along with the design and build of special-purpose machines. The aim of CES is to build lasting customer relationships by working with integrity to provide cost effective solutions, providing mutual security for both parties.

CES made its first step into CNC milling by investing in an XYZ VM 4000 bed mill, with Willams outlining that it was the ProtoTRAK control that made the company gravitate towards XYZ.

“As with many companies, our first step into CNC was made with great trepidation but we gelled with ProtoTRAK control,” he confirms. “Since that first machine, we now have seven more XYZ bed mills with different capacities and generations of controls, along with a flat-bed lathe that also has the ProtoTRAK CNC.”

This progressive and forward-thinking business located just off the ‘Heads of the Valleys’ in South Wales has now made further investment to enhance its capability and help to improve productivity.

Chris Bow, design director at CES, explains: “The bed mills have served us well and continue to do so, but it became apparent that we needed to try something different on our next machine tool purchase to remain competitive. When we’re not successful in winning work following a quote, we always look at why didn’t we win the job. These investigations led us to look at our machining capability.”

He continues: “We arranged a visit to the XYZ head office in Devon to look at several options. On our return we concluded – following the advice provided by the XYZ sales team – that the 750 TMC with its enclosed layout would be a good fit for our business.

“We knew the TMC would allow us to improve material removal rates and reduce cycle times due to its 11 kW BT40 spindle. In addition, the travels of 743 mm in the X axis and 425 mm in Y, mated with the 20 station BT40 tool changing carousel, would open up the opportunity to load a number of parts on the bed at the same time. In turn, this would push us towards lights-out machining and subsequently help us achieve the goal of lowering our manufacturing cost per part.”

Chris continues with the justification of the purchase by adding: “Another improvement for the business was better staff utilisation due to less operator input during component manufacture. The potential to walk away from the machine for the whole of the process brings its own increase in efficiency, creating more capacity within the workshop and helping to reduce takt time when we build one of our special-purpose machines”.

Now the new machining centre is up running, CES is benefitting from the flexibility that the XYZ TMC range offers. Having taken advantage of the optional front-mounted electronic handwheels, all the programmers and operators at CES can jump on the machine and use it in a manual capacity for simple machining operations if required.

The transition to the XYZ TMC from existing bed mills at CES was easy due to the resident conversational programming in the control. Having made an investment in CADCAM software, CES is now in a position to use all of today’s latest technology, both on the ProtoTRAK 15” touchscreen RMX control or through CADCAM to manufacture parts quickly and cost effectively.

XYZ’s TMC (Toolroom Machining Centre) brings the added versatility of a tool-change system, while maintaining the familiarity of the latest version of the ProtoTRAK control system. The use of the RMX ProtoTRAK CNC provides a high level of familiarity for exiting users of XYZ bed mills. For those not familiar, its touchscreen interface and easy-to-use programming tools make the control suitable for low-to-medium production batch sizes. Combining that with a fully enclosed machining envelope and either a 12- or 20-station automatic tool changer, make the XYZ TMC a great choice machine for any business looking to step up productivity.

“The one thing that we didn’t see coming when the machine was installed was the enthusiasm from the team of machinists here at CES,” reports Chris. “They all have a desire to use the machine and help the business reap the benefits of this new technology. Due to software enhancements – such as the ‘defaults’ setting where operators can set the control features to their own liking, the TRAKing feature to put them in control by winding handwheels to execute the program, and the fact the machine has been fitted with a swarf conveyor to cut down on machine cleaning time – all the team have shown willingness to get involved.

“This is helping the company move forward and be more competitive when it comes to quoting for work as the enthusiasm from the team means they’re now looking at manufacturing parts in a different way and employing production methods that were not possible on our older machines. It’s not just the machine that’s making a difference here at CES but the staff too.”

Today, the workshop team at CES is able to offer a complete range of services from CNC milling and turning, through EDM to metal finishing and machine building. The company’s acquisition of the adjoining unit in 2021 allowed it to expand into clearly defined work areas, giving a more controlled production flow from workshop through build and inspection.
