With the shift in the Australian manufacturing sector towards small to medium sized niche operations, comes the increasing demand for specialist high-performance cutting tool solutions.
The machining of the complex parts, with intricate forms and profiles, has resulted in the need for local suppliers to deliver special cutting tools with unique geometries and advanced ceramic coatings in rapid delivery times.
Since 2016, Guhring has supplied customised cutting tools from its Production and Service Division based in Melbourne. The major growth area has been the supply of custom-made solid carbide rotating cutting tools. The high-performance range includes step drills, form/profile end mills, special reamers, compression routers and day model cutters. Encouraged by this success, Guhring has just announced a major new investment in CNC grinding and PVD coating equipment to further support local manufacturers.
“High productivity, excellent economic efficiency and optimal machining have been the hallmarks of Guhring products for over 100 years,” says Brendan Smith, Managing Director of Guhring Australia.
Guhring customers’ trust is well-founded, with tool material, geometry and coating all perfectly matched to one another. Guhring’s revolutionary coating technology, complemented by state-of-the-art R&D, ensures technological leadership in rotary cutting tools worldwide.
Guhring Australia sources carbide rods exclusively from its production plants in Germany, to ensure the highest-quality materials. The grinding of special tools is done on Guhring-built CNC grinding machines and PVD coatings are deposited using advanced coating technology, developed at the company’s coating machine building division in Berlin, Germany.
Guhring-built seven-axis CNC grinding machines are utilised in its Melbourne production facility. A major upgrade of the PVD coating machine has helped to reduce delivery times and increase the range of products available.
“We are fortunate to be able to harness global expertise locally to best meet the strict delivery requirements of the most technologically astute customer.” adds Smith.
Super-fast special tool delivery
The time required to supply special carbide cutting tools is influenced by three factors: the supply of raw materials, the machine capacity in the grinding division, and access to an advanced PVD coating chamber.
The Guhring grinding division operates 24-hours per day mid-week, as well as regular weekend shifts to keep delivery times at a minimum. The team of highly skilled staff are specialists in small batch production of complex and intricate cutting tools. We are constantly investing in new CNC machinery to help reduce delivery times even further. The on-site PVD Coating Division at Guhring operates two shifts per day and provides a rapid coating service for special cutting tools. Urgent orders can be PVD-coated and ready for shipment within hours of grinding.
Guhring has over 47 service centres in all corners of the world. To maintain the highest standard in special tool production, Guhring uses a central tool design database located at its headquarters in Germany. This can be accessed online directly by the Melbourne office. The online SAP-integrated database uses Guhring’s own standard tool templates for designing special tool types such as step drills, profile end mills and reamers. The custom designs are then allocated a unique tool number. Production as well as customer approval drawings are issued via email. Using such a centralised system allows Guhring to design special high-performance tools anytime, anywhere around the world to the exact same standard.
Minimising machine downtime
An important aspect of maintaining short turnaround times for special cutting tools is to keep machine downtime to a minimum. This is achieved by keeping all production equipment serviced and maintained to the highest possible level. Guhring‘s machines are built by its machining division in Germany. Service, maintenance and upgrades are done by the same technicians that built the machines in the first place. The production staff working at the subsidiaries and the producers of machines in Germany work for the same company. This creates an alignment of knowledge that helps to minimise machine downtime and encourage the upgrading of machines with the latest hardware and most up-to-date software.
The combination of a large carbide stock, in-house CNC grinding and PVD coating makes Guhring the one-stop-shop for the supply of special tools in the fastest delivery times. The success of small-to-medium niche manufacturers of specialised and complex parts has resulted in a growth in demand for custom-made precision cutting tools. Guhring has recognised this growth in demand and responded by expanding its local production and service division with the installation of grinding machines and a major upgrade of its advanced PVD coating unit. The investment has significantly increased Guhring’s capacity to produce special carbide tools to meet unique customer demands. It all comes down to delivering sharper, more agile thinking, as required in today’s highly competitive manufacturing world.
