Manufacturing Technology

Double spindle turning machine Sacma’s range of CNC machines for secondary operations meets the needs of productivity and precision required by this specific market. The range includes three machine architectures: single spindle, double spindle and multi spindle (four) on an indexing table. The machines are equipped with leading-edge equipment (direct drive technology coupled with torque motors), allowing high performance and precision. Multi spindle configuration allows for the maximum productivity, making possible the execution of diverse operations in overlapping processes. Parts loading and unloading can be performed in a dedicated location, keeping the working part in process over the spindle. Sorting and feeding can be optimised by customising the solution to each machine based on each part and the needs of the client. All spindles are indexable and inde- pendent, which allows for optimisation of feeding. The machines can be customised with various feeding solutions, such as vibrator bowls, linear vibrators, motorised belts, robotics and

Three-axis wire forming YHM Springtech Machinery Co is a Taiwanese company that has been involved in wire forming machinery since 1987.

Options include standard cams and tools for quick set-up, stereo microscope for micro spring set-up, micro payoff for micro wire, profile magnifier for production monitoring, and spring gauge for spring measuring and offset. The company states that it is dedicated to the development of its machines, and it has progressed from two-axis to three-axis machines, all controlled by servo. The working range of pitch and outside diameter dimensions of the three-axis machine are wider than the two-axis machine. By simply entering the program, it is easier and faster to set up different complicated compression springs. Regarding consistency and speed, for common compression springs the three-axis machine is still competitive with the two-axismachine. Themachine can run 24/7 with a probe gauge, decreasing labour requirements. YHM’s latest technique for tooling is UVw surface treatment, which provides a glossier surface in order to efficiently avoid wire scraping and heating during production. With UVw surface treatment, the production rate can be increased by 30 to 50 per cent, and the cycle time of tooling can be enhanced two to five times. YHM Springtech Machinery Co www.wire-machine.com.tw HTL claims a global reputation in the fastener tooling markets for quality tooling solutions that offer reliability and competitive cost-per-piece production, specialising in safety- critical applications, rolling after heat treat and rolling exotic materials. Its range includes flat dies, cylindrical dies, forming dies, planetary dies, medical products and aerospace punches. Reed has been involved in the manufacturing of machines and tooling for the fastener industry for more than 90 years. The company’s manufacturing facilities, in Auburn, USA, and Haryana, India, specialise in cylindrical thread rolls, flat milled dies (licensed products), flat dies, planetary

The company has developed machines for bending, forming, coiling, winding, stamping, chamfering, stripping, threading, tapping and heading actions with wire, tube, strip or stock material. Machines of the CNC spring coiler series can be used to produce items such as cylinder springs, compression springs, conical springs, hourglass springs and flat spiral cables for many industry fields.
