Douglas Curtis Machine Tools Ltd was founded in 1973 by the late Douglas Curtis and his son Rick, with the proceeds from the sale of their toolmaking company, previously established in 1961. DCMT saw the need for “as new” rebuilding services to users of metal-cutting machine tools. Although market conditions were tough during these years, DCMT’s commitment to quality and customer support enabled it to flourish.
It was evident during this decade that besides accuracy and reliability customers needed greater productivity, and advances in industrial control systems offered the opportunity to extend the productivity of existing machines by retrofitting electronic control systems. This in turn facilitated automation of parts handling, and enabled enhancements in quality control using both proprietary and bespoke gauging.
During this decade, DCMT was undertaking increasingly ambitious projects demanding design, prototyping, integration with third party equipment, documentation, and post-sales backup in areas including grinding, honing, assembly, and testing. Parts handling grew to become significant, with modularised systems being applied to multiple stages in part manufacture.
The years around the turn of the Millennium saw the evolution of DCMT into 3 companies, directed towards:
- Product assembly and functional test systems
- Design and manufacture of specialist grinding equipment Douglas
- Special purpose machinery and automation systems
In 2005 DCL and CMT were reunited under the CMT banner, to pool their resources in developing a new small parts cylindrical grinder. DCL had developed a portfolio of grinding machines such as:
- Novel “UCG” for difficult centreless applications
- Diamond face grinder with very high cutting forces
- Cam-ring grinder with extremely precise high speed contouring
- Diesel injector needle grinders
- Wheel-bearing face match grinding with under-load gauging
- Face-and-thread grinder for fuel injector parts
- 4-axis grinders for spiral grinding
- Multi stage bore, seat and face grinder
CMT’s continued machine development programme gave birth to the Vector. The new machine would benefit from these innovations, and aim at a more clearly defined customer base.
Like earlier DCL machines, parts handling was to be integral with the machine. Key features of the Vector were:
- Retention of high-pressure grinding fluid
- Flexibility to accommodate pre-and post- grind operations such as gauging and deburring
- Suitability for linking into sequential manufacturing cells.
The first two ‘Vector’ grinders were sold in 2006 to a customer grinding diesel injector parts. There followed a period of market led application developments, leading to numerous variants in workpiece presentation and holding, and process refinements in respect of grit types, fluids, machine parameters, monitoring strategies and secondary operations.
During 2009 CMT succeeded in winning orders for two full production lines, the first Vector based cells incorporating modules from third parties that were integrated by ourselves.
In 2013 we sold our first (and only) rotary transfer face grinder.
The experience gained to-date from over four decades of machine tool design and manufacture has stood us in good stead for future growth, recognising the need to invest internally on new development projects, technology and to attract talented and innovative engineers.
We continue to improve and develop the Vector machine according to our customers’ application requirements, both in existing and future market sectors.
Curtis Machine Tools Ltd remains constant to Doug and Rick’s guiding philosophy and determination to provide the best products and service. Our proven success within the bespoke engineered machine tools sector is a direct measure of our ability to contribute to the success of our customers.
