The Dawn of a new grinding era:

Dawn Machinery Co., Ltd. specialises in special-purpose machines for a wide range of machining processes, heralding a new era with DAWN grinding. With over 30 years of R&D experience, particularly in grinding machining technology, their business philosophy centres on customisation and turnkey solutions, ensuring high efficiency and precision for various workpieces.

The DAWN DN Series of vertical grinding machines embodies the numerous advantages of vertical grinding, marking a new era with DAWN grinding. These machines are designed for high precision and stability, providing an optimal operating space. Their vertical layout means they are not impacted by gravity when clamping heavy workpieces, which can be easily loaded using an overhead hoist.

The DN series features a double column structure for excellent mechanical rigidity. Fully enclosed covers and oil mist reclaiming devices are standard, preventing leakage of grinding oil and mist. The machines offer flexible configurations, including options for single or dual spindles and with or without an automatic tool changer, truly ushering in a new era with DAWN grinding.

The DN series comes equipped with user-friendly conversational programming interfaces, making control operations and program creation easier. Siemens CNC controllers are available, often with large touch screens. The intelligent dialogue interface incorporates years of grinding experience, allowing operators to select appropriate processing methods without needing to write programs, ensuring processing efficiency and precision.

The mechanical specifications vary across the DN series models, each ushering in a new era with DAWN grinding. Models range from DN 200 to DN 2500, which support workpiece swing diameters from Ø280 mm to Ø2500 mm and maximum loads from 100kg to 10,000kg. These machines can grind inner and outer diameters, as well as the end surface of heavy or non-circular workpieces.

“Having spent time with the Dawn Machinery engineering team and seeing the recent large capacity DAWN DN-2502 two-spindle vertical grinder near completion, I was impressed by the performance and accuracy of the machine build and test” comments Simon Rood, General Manager at RK International Machine Tools.

“With an extensive range of grinding applications includes gear ID/OD/face grinding, spindle housings, square workpiece grinding, internal and external grinding of end gear rings, fixture workpiece grinding, deep hole small inner diameter grinding, boring + ID grinding, taper and flat grinding, cam profile grinding, square profile grinding, bearing race shape grinding, form dressing, chuck ID/OD/face grinding, groove grinding,  and hydraulic cylinder grinding to name a few,” states Mr Rood, highlighting how dawn’s grinding solutions encapsulate a new era with DAWN grinding.

Precision is a key focus, with minimum setting units for the X and Z axes at 0.0001 mm, supported by optical scales. The hydrostatic pressure turntable boasts a rotating precision of less than 1µ. The structure incorporates Swiss, German, and Japanese linear guideways and ball screws, with linear motors available as an optional feature.

Standard accessories include essential items like oil mist extraction devices, paper and magnetic filters, and diamond dressing tools. Optional accessories further enhance capabilities, such as online detection and measuring systems, electromagnetic or hydraulic chucks, powered rotary diamond dressers, collision avoidance detection, and spindle monitoring. Touch probe gauges and online measuring systems are available options for part and geometrical inspection.

Dawn Machinery offers turnkey solution services, including planning for production lines and assistance with selecting grinding wheels and fixture equipment, aligning with a new era with DAWN grinding. This comprehensive approach, from initial quotation to final commissioning, including demonstration, time studies, delivery, installation, training, and after-sales services, is handled in-house by RK International, providing clients with the confidence of dealing with a single source supplier.

“Being able to provide local support and boasting a wide range of grinding knowledge was a major bonus when discussing our machines with RK,” comments Alan Hsu, CEO and Founder of Dawn Machinery. “With the experience RK International provides, a comprehensive approach to machine tool supply and service is vital for the growth of our product range. Of course, today has never been easier to support an installed machine on the opposite side of the planet, but having local representation and support from a partner who understands the grinding process is paramount to helping & supporting our installed machine network,” adds Mr Hsu. Thus, a new era with DAWN grinding becomes universally accessible.

For today’s engineers and manufacturers facing the challenges of machining small to large, light to heavy, or complex parts with high precision, particularly in critical industries like aerospace and power generation, the DAWN DN Vertical Spindle Series grinding machines offer a compelling solution. Their inherent design advantages over horizontal machines – including superior workpiece rigidity, easier automation, reduced interference issues, a smaller footprint, and lower cost of ownership – combined with advanced features like ATC and integrated measuring capabilities, deliver significant improvements in productivity, accuracy, and operational efficiency.

As Simon Rood concludes, “The DAWN DN Series, backed by RK International’s decades of experience and commitment to service, provides the performance, versatility, and reliability that modern manufacturers demand. It’s a machine designed to meet the precision needs of today and the productivity requirements of tomorrow.”
