Precision - Import export

Shinano Kenshi is one of the world's leading OEM manufacturers of stepper motors, servo motors, brushless DC motors and custom motors.

The classic solution for many slip ring applications: At MACK you will find the right leg brush holder for your technical requirements. Without any doubts. Our tried and trusted holder model is available with one or two legs, with fixed or adjustable carbon brushes, in metal or – as a special version – in plastic. Together we can develop the individual version that meets your requirements. As with most MACK products: We do everything ourselves, and only in our own facilities – from the production of the main parts to the completion of all assembly work. This is how we can guarantee you maximum precision and process security.

Our high-precision glass beads are usually made of soda glass or borosilicate glass, but on request we can also supply quartz glass, sapphire glass or optical glasses. The standard tolerance is ± 0,02 mm. Without surcharge, the surfaces can be supplied matt or polished. You need even higher precision? No problem: We can also supply customized glass beads with tolerances of ± 0,01 and ± 0,005 mm. Precision glass beads

The portal and multitasking machines of the P series offer maximum precision and flexibility for machining large, complex and high-precision workpieces. Outstandingly suitable for machining prismatic and cubic workpieces in a single set-up and mounting position. An extremely heavy cast iron design with optimum damping properties and the INA linear guiding system equipped with hydro mechanical damping slides provide the basis for the ultra-modern table and gantry design portal machines. Areas of application: Mechanical engineering, new energy, tool and mold making industries, subcontracting sector and other industrial markets with very large, complex, and precision workpieces. - Table or gantry design with clamping tables of any size and NC rotary tables - Multitasking: Milling and turning on one machine Longitudinal (X): 3,000 mm - unlimited Vertical (Y): 1,500 – 3,000 mm Cross (Z): 4,000 – 10,500 mm Crossbeam (W): 1,000 – 4,000 mm

Examples of applications include pressure switches or thermostats: Deep-drawing techniques to manufacture seamless tubing up to 50mm ID and 450mm length - in wall-thicknesses as low as 0,064mm. Based on this, our smalles precision bellows start with only 6X4,2mm. Mainly requested with individual bottom shape, they are performing as reliable force transmitters. Besides bronze and brass, stainless steel and other alloys are available.

Stainless steel bellows, formed from seam-welded thin wall tubing Stainless steel bellows, formed from deep-drawn seamless tubing Bronze and Brass bellows for measuring and controlling applications Hydroformed bellows from exotic alloys as Beryllium copper or Monel400 Customized designs and end forms, also off-the-shelf standard solutions Special coatings on demand

Deep-drawn tubes from stainless steels (with a closed side or open) Deep-drawn tubes from non-ferrous metals as bronze, brass,... Seamless sleeves made with stamping processes Ultra thin-walled tubing in Beryllium copper or other special alloys Annealing services in vacuum furnaces Washing technologies for soap and oil The precision tubing is needed at Mera Bellows to manufacture seamless metal bellows.
