Mach 2010 Preview Information

High productivity workholding and machining equipment to be showcased Workholding and machining systems specialist, 1st Machine Tool Accessories (1st MTA) will be exhibiting a wide variety of new productivity enhancing equipment for the first time in the UK. Chucking and rotary table developments from Kitagawa Europe will include the company’s NV, QJR and DHP/DHF series collet chucks, as well as GT series rotary tables. In addition, the company will be showcasing Chick’s recently-launched One-Lok advanced CNC workholding system and the Darex XT3000 semi automatic drill refurbishment module, along with versatile Alpha Magnetics magnetic workholding equipment and the extensive range of Tecnomors automation grippers, indexing chucks and manual 5th axis vices. Kitagawa’s new NV chuck range has been developed to meet demands for large vertical lathe power chucks. Produced in eight models for components from 62 to 1000 mm diameter, NV series units feature a protective jaw cover and scraper system that prevents the ingress of swarf or coolant into the chuck mechanism. They are rated for maximum speeds up to 2900 rev/min and are designed for use with standard range Kitagawa jaws and Y2035R type cylinders. Kitagawa’s latest QJR08, QJR10 and QJR12 quick change chucks are interchangeable with the company’s popular large through-hole B208 / B210 / B212 and BB208 / BB210 / BB212 models. The new units’ base jaws, which are rapidly and simply changed using a manually operated wrench, feature metric serrations to accommodate a wide variety of popular jaw types. Recently-introduced Kitagawa DHP and DHF collet chucks provide secure and accurate clamping of components up to 65 mm diameter. DHP variants generate a powerful pull back action for first operation work, while DHF models feature a removable bore stop, fixed collet position and high accuracy to ensure precise second operation machining. The compact new chucks are offered with standard A5, A6 and A8 mounts to suit all popular machine tool types and have been designed to be both compatible and quickly interchangeable with other popular quick change collet clamping heads, without the need for special purpose adaptors. High clamping torques, extreme rigidity and fast operation are key features of Kitagawa’s new GT series heavy duty rotary tables. Available in three models with tables from 200 to 320 mm diameter, the new units incorporate a novel piston design that delivers component clamping torques of up to 2800 Nm. Productivity is further enhanced by the tables’ rigid yet compact design, which allows maximum metal removal rates to be combined with high indexing accuracy and repeatability. The GT series also features a rapid clamping action for reduced cycle times and maximum production throughput. Providing the speed, precision and flexibility demanded by modern CNC machining operations, Chick’s One-Lok eliminates the shortcomings of standard knee mill vices based on 1950’s technology. Its maximum grip capacity of 17 in (432 mm) is complemented by Chick’s new ‘Boltfast’ jaw system – enabling jaws to be replaced quickly and efficiently with a locational repeatability of 0.0008 in (0.02 mm). The system’s compact, modular design also features innovative ‘squeeze’ clamping, which imparts a pull down action and virtually deflection-free clamping with a maximum retaining force of 4.5 tonnes. The Darex XT3000 semi automatic drill refurbishment module ensures rapid, accurate and cost-effective drill sharpening, regardless of operator skill levels. Fulfilling international aerospace standards for controlling key geometry, the new module delivers faster and more accurate regrinding of drills up to 21 mm diameter by ensuring precise control of drill set up, sharpening loads and cycle times. 1st MTA will also be marking its recent appointment as agent for US-based Alpha Magnetics with an extensive display of the company’s magnetic workholding equipment. Products on show will include the versatile A-pod workholding system, Eagle Lift magnetic lifting equipment and APB / AMR series milling magnets. 1st MTA’s comprehensive range of workholding solutions will also be complemented by a display of Tecnomors self-centring automation grippers, indexing chucks and 5th axis manual vices. In addition, the company will be demonstrating numerous examples from its long established and proven machining and workholding products ranges, including Abbott and Leave fixturing and clamping products; OK-Vises; Brighetti reduction bushes; CoolJet high pressure coolant systems; Micromag filtration units; machine mounts; and Overbeck deburring twister lathes.
