02mm. The height of 9 top post is 10mm, the diameter is 0.
1mm. All these structures are to use 4mm to establish milling cutter to be in what the treatment when 15000r/min and 600mm/m comes out to say according to the company, the characteristic of this kind of design is to move quiet, have hardly inertial and definition is high. Accordingly, this machine tool very apply to the workpiece such as the medical apparatus and instruments with treatment very slashing requirement. "Actually, this machine tool is had enough precision, stability and but repeatability, can be in same aspirant travel rough machining, semifinishing machining mixes a platform finish machining. " Larry Jones of selling manager of NTC company district says so. Differ with the machine tool of the indirect opening that uses component of ball, metal to serve as motion and dormant component, z μ 3500 introduced pressurization oily film. Mechanical component slides along oil, won't contact directly between, eliminated the friction that creates vibration and hot accumulation thereby. "And, stick the structural configuration of slippery motion in order to reduce so, clearance vacillate phenomenon also is a problem no longer, because the change of linear electromotor direction is completed for an instant almost, " Mr Jones says, "Such, when doing circularity test, the machine tool can maintain those who be less than 1 μ M is homocentric degree. " he compares this action ice hockey competition. "The ice hockey that float resembles float going up in air in the component on oily film, " his explanation says, "When hitting it gently, it flies, hit a certain corner, fly to another direction again next, seem to need not be overcome it seems that inertial. " a lot of machine tools are mixed in null of operation personnel setting undertake other before each preparation works, must move a few minutes to undertake first " warm-up " . The temperature after because of the machine tool movement rises rises, the bearing of the machine tool and other metal component can expand a little and affect precision. However, z μ 3500 because have the design of metalloid contact, together with 60UKgal (1 UKgal=4.
54609dm3) cooling device is oily to hydraulic pressure static force undertake recycle and make its maintain low temperature, the machine tool starts several seconds to be able to throw the job instantly. Additional, operation personnel also need not worry can temperature rise causes deviation to need to undertake compensating process designing. This machine tool is compared other a lot of congener machine tools want quiet much, because its machine noise exclusively,be the sound that cutting tool comes up against workpiece. Quiet, the workshop of little interference is very beneficial to employee. Because do not have metallic contact, mechanical component wears away not easily, prolonged the life of the component so, reduced maintenance cost. Say according to Mr Jones, change two years oily, change 6 years oily filter -- to maintaining for system of hydraulic pressure static power already enough.
