August 18, 2011 12:05 pm
Murata Machinery, Ltd. (brand name ‘Muratec’) is a global leader in providing state-of-the-art technology for CNC Turning process fully integrated in-house with built-in automation for a wide range of applications, especially for the medium and large volume production industries. Muratec has accumulated over the past 2 decades, application know-how covering a wide range of components, simple to most complicated and high precision requirements. Fully servo-controlled 3-axis Integrated Gantry Loaders are the key solution offered with every type of machine in the full range to handle work pieces up to 350 mm diameter, weighing up to 20 Kgs.
Muratec’s automation solutions include not just loading and unloading the work pieces from the machine chucks with the unique gantry loader chucks, but also full range of peripherals for work piece feed-in, poka-yoke, turnaround from one operation to next, washing, post-process gaging, feed-out, transfer and line layouts. For each of these peripherals, Muratec has standardised modules to cover a range of product sizes or designs and builds customised solutions to match individual production volumes and variations. Ultimate aim of automation is to achieve high levels of efficiency of productivity on 24×7 basis with stable quality-controlled production output.
Work piece Feed-InMain factors to decide the type of feed-in unit are:• Ease of feeding the work piece by even semi-skilled labour• Stock volume to let the full system operate unattended for certain minimum period such as lunch time break• Ensure that every work piece is picked up by the gantry loader in safe environment and stably load onto the machine chuck.
The most standardised solution to cover a wide range of round or non-round, symmetrical or non-symmetrical work pieces to feed-in, is the pallet feeder. Basically there are 2 types: stacking type and flat non-stacking type. The pallet jigs can be easily designed and manufactured locally if required to suit the input casting or forging or cut bars of varied shapes. For round work pieces, the simple 3-pole setting design adds to flexibility and reduction in set-up change time as well.
Re-chucking / Poka Yoke stationDepending on the quality of the feed-in material, simple re-chucking station is provided which can be designed for Poka Yoke check as well. This eliminates wrong or improper work piece loading and thus avoids accidents and damage to chucks.
