We all know that the Covid-19 pandemic has had a huge impact on our everyday lives, from socialising and seeing our families, to working from home. The British economy shrank by nearly 10% in 2020, this is the biggest slump in more than 300 years. But now, in May 2021, things are looking up, with the prospect of vaccines allowing us to go back to a new normal. There are some initial signs that a wave of optimism has swept British companies as the economy gradually reopens following a third national lockdown in the past month, with pubs reopening and non-essential retail opening their doors once again. The country is beginning to recover from the large slump caused by the global pandemic.

UK manufacturing

UK factories were not directly affected by the lockdown restrictions at the start of 2021, many of their customers were. Meaning many took advantage of the furlough scheme offered by the UK government.
April saw an acceleration in the rate of the UK manufacturing industry. Growth of output as well as orders were among the best seen in seven years. In a recent survey, nearly half of smaller British manufacturers are expecting to recover their pre-pandemic health in the coming months, many of these plan to invest in hiring, plant and machinery. The South West Manufacturing Advisory Service (SWMAS) and Manufacturing Growth Programme said 48% of small and medium-sized manufacturers expected to meet their pre-COVID position in the next three months. The IHI Markit/CIPS Purchasing Managers’ Index® rose to 60.9 in April, up from 59.9 in March. The latest reading is the highest since July 1994’s record high 60.0.

Impact on CMT

Curtis Machine Tools were impacted by the pandemic, just like thousands of other business in the UK last year. Fast forward to the first half of this year and business is booming. We have received enquiries for standalone and production line machines from across the globe and even managed to pick up new customers. These customers are currently really impressed with our customer service and grinding solutions we can provide. In May 2021, we will have dispatched 3 VECTOR Twin grinding machines as well as having various initial consultations with potential customers, and development projects taking place.

Our latest VECTOR Twin grinding machine has been dispatched this week, ready to be delivered to our customer, a major automotive supplier, in the USA. Manufacturing this machine has taken several months of designing, assembling and testing to make sure it is to the exact requirements of our client.

VECTOR Twin

The VECTOR Twin can be used to grind a number of different components, depending on the requirements of our customers. Many of our customers manufacture small, high precision components within the automotive, medical and defence industries. The Twin, from the VECTOR family of grinding machines, inorporated an indexing twin-spindle workhead, this allows loading and some secondary operations to be performed concurrently with the grinding process. Using this machine means that the process can be nearly halved in time, therefore improving productivity.

This particular machine uses a conveyor system which holds a number of pallets containing components. This reduces the amount of human interaction that the machine needs to operate. Once the pallet has finished being ground, the conveyor system moves it to the end of the machine, ready for the operator to pick up. An SPC drawer has been incorporated into the machine to allow the operator to inspect finished components whilst the machine is still running. This machine also features a Staubli robot and Siemens control system.

CIMT 2021

CIMT (China International Machine Tool Show) 2021 was a huge success for the machine tool industry. Unfortunately, colleagues from CMT and many international attendees were unable to attend, due to Covid-19 restrictions. Our representatives at Rieckermann attended the show to meet with potential customers and showcase the engineered grinding solutions CMT can provide, with our 45 years’ experience in the machine tools industry.
Some of our team at our headquarters in Essex, UK were available to take part in video calls to speak with potential clients. Rieckermann team members had some in depth discussions about what CMT can offer, the capabilities of our machines and the requirements of potential customers.

CMT and Rieckermann worked closely to ensure we could provide attendees with the best possible experience. We created a slideshow that was interactive on the stand for viewers. CMT also send out a number of different components that our VECTOR family of grinding machines would be able to manufacture. Employees at Rieckermann were also helpful with translating documents into Chinese, and printing copies ready for the show, see below for the link to our Chinese (simplified) Brochure.

Although our team was disappointed to not be able to attend CIMT, the use of technology made the event enjoyable. However, we hope that in the future we will be able to attend exhibitions in person to build a better relationship with potential customers. CMT were very impressed with the professional stand at CIMT and thank them for their hard work.

VECTOR Twin and Quad

Is a well-established British manufacturer of high precision grinding machines for small components. We supply bespoke engineered grinding solutions to manufacturers worldwide and have over 45 years’ experience within a variety of industries, such as automotive, cutting tools and defence.
   Our Grind in a Box patented technology has proved to be a global success, based on this innovative concept, CMT have designed and manufactured the VECTOR family of grinding machines. The Engineering team at CMT are constantly developing new machining methods and applications that are precisely tailored to the needs of our customers and market conditions, in order to maximise the efficiency of production. The integration of additional processes such as:

  • Vision systems
  • Automation
  • Workpiece inspection
  • Deburr, wash and dry
  • Laser marking, packaging and much more.

These are designed, developed, and integrated into the VECTOR, providing a complete turn-key process. CMT offer limitless possibilities to engineer and implement the user-specific requirements. With hundreds of machines ranging from a standalone solution to fully automated production lines, CMT is one of the market leaders in this field and your partner when it comes to process orientated solutions.
Our machines are fitted with the latest technology, including Siemens control systems, and our engineers have a high level of understanding using both Fanuc and Staubli robotics.

All the VECTOR machine variants share the same grinding platform, with a long radial stroke and a short axial stroke, for single and multi-plunge operations or peel grinding of profiles. VECTOR machines have been designed to give maximum productivity and precision with an exceedingly small footprint, providing an excellent ROI.

VECTOR Twin

The VECTOR Twin incorporates an indexing twin-spindle workhead, allowing loading and secondary operations to be performed. This additional spindle allows loading and unloading to take place whilst grinding is in process on the other spindle, giving a spark-to-spark time approaching zero, making it ideal for cycle time optimised production.

VECTOR Quad

Vector Quad

The VECTOR Quad is based on the proven VECTOR Twin, revolutionising production grinding. The Quad uses an innovative four-spindle workhead, enabling the outer diameters or contours to be ground simultaneously on two workpieces, using the same grinding wheel, doubling the output. The Quad has a maximum diameter of 45mm.

Vector production grinder

With more than 40 years’ experience in producing engineered grinding solutions for high volume production environments, Curtis Machine Tools continues to enjoy global success with its range of VECTOR production grinding machines and is celebrating the sale of its 100th VECTORTM grinding machine to Cummins in the USA for the production of diesel injection components.

 

A market survey in 2005 showed that over 90 percent of all grinding applications had a grinding length of less than 75mm, with the key market being high precision fuel injection components and turbochargers. CMT reacted to this survey and developed the Curtis VECTOR range with a grinding length of 100mm and integrated 3-axisloading system designed for high volume cylindrical grinding, typically 250,000 to 1,000,000+ parts per year.
The first VECTOR grinders were sold in 2006 to a customer in India grinding diesel injection components. From this point, the VECTOR has seen continuous development, enabling CMT to offer a multitude of options in workpiece presentation and holding. This, combined with process refinements in respect to grid types, grinding fluids and machine parameters, has given the VECTOR a truly market leading set of performance characteristics.
The key to optimising cycle times on high volume grinding machines is to reduce the ‘dead time’ to a minimum. The VECTOR Twin is the advanced machine in the range, having two work spindles mounted in an indexing drum, allowing loading and grinding operations to be carried out concurrently, giving cycle time reductions of up to 50 percent.

grinding area

This photograph shows the working area of the VECTOR Twin with its main feature: When the door is closed, the grinding area is sealed and all coolant and debris is contained. The coolant is piped through the bottom of the guard and mist is removed by an integrated extractor for conventional grinding. For high-speed grinding a separate unit having a higher capacity is used.

The grinding wheel is mounted on cross slides, allowing grinding to take place by moving the wheel to the left and dressing by moving to the right. The dressing unit behind the grinding wheel is either fixed, rotary disc or diamond roll.
The left-hand wall of the fixed guard is a divider plate between the two work spindles. These are mounted in a drum that can be rotated through 180 degrees to index the spindles between the grinding and loading positions.
The splash guard, above the grinding wheel, rotates round the wheel so that when the wheel is retraction for loading, the splash guard covers the front of the wheel, stopping any coolant being released by the wheel being thrown past the divider plate as the workhead indexes. Grinding takes place on the spindle within the dirty area, while loading takes place in the clean area.

VECTOR Twin

Grinding and loading therefore take place at the same time. The index time for the workhead drum is 1.2 seconds, giving a part to spark time of less than 2 seconds. In addition, secondary operations can be carried out on the component in the loading position, such as brush deburr, post process diameter gauging, pre-process length positioning, washing, laser marking etc.
As the coolant and grinding debris are totally contained within the fixed grinding guard, the pick/place locations can be close to the work spindle. Loading systems can be integrated into the without any risk that the loader slides will become contaminated. This makes for short robot movements and allows the machine to have a very small footprint of only 1,200 mm wide, including the loading system pallet storage for the components.
The fixed guard also makes all machines in the VECTOR range suitable for high speed super abrasive grinding wheels, as the wheel and high-pressure coolant are fully enclosed.
