Hemel Hempstead-based Microprecision – a specialist in the field of precision component manufacturing – is now exclusively distributing a high precision and cost-effective range of CNC gear production machine tools from South Korean company S&T Dynamics.
Microprecision was founded in 1978 to provide precision engineered subcontract parts to the civil, military, aerospace, motorsport, medical, and commercial markets. Today, the company specialises in the manufacture of components that include a gear element such as gears, rotors and actuator parts.
As a supplier to the aerospace industry, Microprecision holds AS9100 Revision C registration in addition to NADCAP accreditation for chemical processes and NDT. Microprecision Machine Tools began in 2010 in order to retail key specialist machine tools that the company used on its own production site.
The range of gear production machines from S&T Dynamics, which includes hobbers, shapers, shavers, deburrers and associated accessories, offers quality levels normally seen on top of the range machines, but without the price premium.
The company's faith in the capabilities of the range is reflected in the fact that it uses two brand new S&T machines in its own 20,000ft² manufacturing facility – which it uses not only for its own advanced production, but also for customer demonstrations.
Indeed, before making the decision to act as a distributor, Microprecision made sure the machines could meet the demands of the aerospace industry – with extensive inspection and testing of machined components before they were shipped. Once the machines and the manufactured components passed Microprecision's quality control standards the decision to distribute the machines was given the green light.
The S&T gear manufacturing range comprises: GHO-200, -350 & -500 CNC vertical gear hobbing machines, each with corresponding bed capacity. This is a powerful range of machines offering high precision capabilities due to low surface pressure and high cutting resistance. With a Global User Data (GUD) resource, separate programming is unnecessary and gear production is reported to be relatively straightforward – all that is required is the cutter specifications, the workpiece specifications and the cutting conditions.
There are two GHO-200 machines installed at Microprecision in constant use and available for inspection and machining trials. Having the two machines in operation in the UK by the vendor means that any prospective purchasers can draw upon firsthand experience on set-up and operating procedures, plus the capacity to subcontract work and train operators on the machines before new machines are delivered onsite. This ensures the customer is up and running quickly – with the ability to ramp up production progressively.
GSP series CNC shaping machines are also included in the range; these 3-axis machines offer high precision shaping via high strength columns and counter columns. They also offer reduced installation space due to a front loading cabinet and the GUD environment for easy programming.
GSV series CNC shaving machines are next in the range. The 4.9kW spindle motors and 3-axis motion combine to offer power, easy operation and high precision. Like the two machines above, they also come complete with a magnetic chip separator to aid chip processing. The GSV range also uses the GUD environment for convenient programming.
TCR chamfering (deburring) machines offer powerful through their high strength, high precision cutting spindle. An inverter also provides the capability to offer a variable speed transmission for optimal control of the work spindle and work slide. Convenience is further enhanced with the simple arm-type control panel that allows the operator to adjust its position.
TCG chamfering machines offer the same high strength, high precision spindle, inverter control, and arm-type control panel as the TCR range. In addition, no separate change gear is needed due to the deployment of a settable split plate.
“With clients across a multiple industries, including civil, military, aerospace, medical, general industrial and motorsport, Microprecision is committed to quality and is happy for potential customers to come and see the machines working in a production environment,” states Microprecision’s managing director, Terry Grubb. “We’re also more than happy for customers to test the machines with their own parts prior to purchase.”
He continues: “If a client purchases a machine, Microprecision can offer training in a production environment, including part programs, tooling and product development. World-class service support is also part of the package, with preventative maintenance, breakdown cover and out-of-hours tech support.”
Although relatively unknown in the UK, South Korea-based S&T through its subsidiaries, provides various products for the defence, wind power train, automotive, machine tools, casting and heat treatment industries worldwide.
Its machine tools include machining centres, CNC lathes, grinding machines, milling machines, gear cutting machines and flexible manufacturing systems. The company was founded in 1959, employs over 11,500 people and has grown revenues to $517.8 million.
