ASG-550 is a four axle servo-control CNC saw grinder; the grinding angles, the teeth numbers, and the teeth depth can be automatically set up and controlled. No mater face grinding, top grinding or saw grinding, all of these actions can be done in one time. Without spending a long time on grinding, this machine can make the high quality and accurate grinding performance. The following is part of the features of ASG-550:

• Ceramic magnet chucks provide superior holding power that never fades, and it is easy to replace the chucks.
• Relief angle grinding can be finished in one action.
  • This 4 axle servo-control CNC grinder allows setting various feeding curves according to different saw blade diameters.
• Installed the basic automatic lubrication system.
• Equipped with standard spray mist filtration system that with cooling water recycle function.

AUTOMATIC HSS CUTTERHEAD GRINDER

Jeffer Machinery’s grinder is accurate and durable that is well approved by customers in both domestic & export markets. “Our grinder exporting to Europe is CE Certified to European standards, and we have attained high quality standards and believe in providing flawless products to our customers,” Mr. Daniel Lin pointed out the high self-motivation that every Jeffer’s worker has. “And each our product is well checked by our QC team before dispatching in order to make sure that our customers get the finest machine. Our products are precise and perfectly suit the purposes they are meant for.”

It is worth mentioning that Jeffer Machinery Co., Ltd. its production process is well documented to make sure continuous process improvement. The whole production process is carried out in-house, no matter preliminary design, production or the final inspection, they are managed through an IT network with CAD, PDM and CAM capabilities. Besides, all Jeffer Machinery grinders are accepted in the national and international markets and are known for their durability and specialized features.http://www.azom.com/news.asp?newsID=19282

The UltraGrind CNC is designed for the precision production environment such as aerospace and higher volume manufacture including automotive, as well as high-precision sub-contract machining for biomedical, high-end process tool/die sets, F1 and motorsport engineering.

Viewed as a key strategic development, a special UltraGrind project team was created to design the machine. They carried out customer surveys not only with J&S customers but many users of other equipment to ensure this project met market requirements now and in the future. From the feedback this team were able to create the specification, build and test the machine to ensure that it achieved the highest levels of accuracy and flexibility always associated with Jones & Shipman machinery. Built on a one-piece bed design, the machine combines great rigidity, stability and stock removal rates whilst maintaining high precision. It incorporates many mechanical, electrical and software features, suggested from the customer research, that ensure it is easier to operate and change over in demanding production environments.

Mike Duignan, Managing Director of Jones & Shipman commented: “The launch of the new UltraGrind machine is an exciting development for the precision grinding industry. The machine brings new standards of accuracy for a one-piece bed grinder, keeping the company at the forefront of the precision tool technologies industries. We will be demonstrating a working prototype at the CIMT so visitors to the Show will be able to see all the machine’s distinct advantages. We have already received a number of orders for the UltraGrind, including one for two machines from a premium subcontractor to the aerospace industry.”

A brand new modular wheelhead design ensures customers have a wide choice of external and internal grinding spindle combinations, effectively allowing the customer to specify a custom machine, but without the cost and build time associated with it. The modular wheelhead design gives wheel sizes up to Ø500 x 100mm (Ø20″ x 4″) and wheel spindle power up to 15kW (20hp), with ultra rigid spindles providing substantially increased metal removal rates and increased productivity.

Angular wheelhead positional accuracy and repeatability are assured via a high precision 1° Hirth coupling. An optional true B axis programmable to 0.001° utilising feedback from a high accuracy encoder mounted directly to the rotational spindle axis, infinitely variable positional resolution can be achieved. The machine currently offers 650mm or 1000mm (25″ or 39″) between centres (with larger machine length capacities planned) and centre heights of 180mm, 200mm and 250mm (7″, 7¾” and 9¾”). The increased diameter capacity (of up to 500mm (19½”)) means there are options to cater for larger mass components up to 450Kg (990lb), and odd shaped components, which can result in high rotational inertia.

The UltraGrind machine uses a brand new Jones & Shipman’s proprietary Windows® based graphical programming software suite, which further builds on the success of the Easy software that removes the requirement for operators to input code, although ISO programming is fully supported and codes can be easily viewed and used if that is the customers preference. The user-friendly software is built around a Fanuc® 320i with touchscreen control system. This reduces the time needed for operator training, machining set-up and changeover times.

Simplicity does not limit flexibility, however. A full suite of dressing and grinding programs are available for the operator. Easy to follow Jones & Shipman set up pages allow the operator to digitise diamond and wheel positions by means of a simple user-friendly touch screen interface. Graphical images that represent programs and set-up are simply touched to program, providing quick and simple input. A wide range of additional options including gauging and autoloading are also available.
