Tapping Machine with 4 mm Tapping Capacity is manufactured by Micro Engineering Works. Micro Engineering Works is an ISO 9001:2000 accredited organization that offers Tapping Machines, Precision Drilling Machines, related parts and accessories. The model number of the machine is PHSTM-TC4-404. In Tapping Machine, the hardened and ground spindle is driven by a specially designed pulley is driven by a F.H.P., single phase mains operated motor to attain High Speed Tapping. The machine provides a stepless Electronic regulator to achieve low and high RPM accordingly. Precision High Speed spindle bearings are housed in accurately lapped bores of its hardened and ground spindle of the main pulley, which forms the basis of extremely accurate machine operations. Conveniently placed control, compact design and precision geometry are some other features. The Tapping Machine with 4 mm Tapping Capacity is useable with Three Jaw Key tightening chuck. The spindle, rotating in Bronze bearing is driven by a frictionless felt mounted pulley. The machines are equipped with a screw depth stop adjustment in the swivel base. The Tapping Machine with 4 mm Tapping Capacity operate on the friction cone principle, giving a high degree of sensitivity and flexibility to avoid breakage of taps which is much appreciated in the field of instruments, watch making industry, electrical industries and spectacle industries.
