Gear wheel 50z for threads and feeds for the MN80 lathe

MN 80 Spindle Pin / Coupling for MN 80 Lathe - that the wheel assembly is solid and free of play. The clutch hole is 10H7, the 4mm pen is recessed into the body. This part complements the toothed basic twin wheel 30/20 and also the toothed wheel 30z. Clutch diameter for couplings is 14mm, identical to gearing gears for lathe MN 80

MN 80 - The toothed gear is very precisely chopped and the chosen production technology ensures the zero rolling of the wheel rims to each other. Everything cut.

Basic gear 30z for MN 80 lathe, including pen Suitable for thread cutting when the value of the replaceable sprocket at the position of the wheel A is not 20 teeth and therefore does not use the basic toothed wheelset 30 / 20 teeth. In this particular case, we must use this gear with a pin and a pin to install any toothed wheel A in the assembly with this wheel as a basis for assembling the gear. This toothed wheel serves as a tray for wheel A, which is mounted on the shoulder. Conversion continues with wheels B and C, which are firmly connected together with the Bronze Clutch and followed by wheel D. The gearwheel is attached to the upper fixed pin of the lyre under the sprockets the speed of the feed screw. In the basic assembly, the toothed wheel 30 / 20z operates in one piece, since the tooth exchange gear 20 has a hole 14H7 and a groove at a depth of 2 mm unmanufactured. if necessary, cutting a thread whose pitch requires a different number of teeth than 20, the wheel shown as a base for the wheel A of the gear set must be installed on the base pin. This part is made with a precise hole 10H7 without bronzing, since it is mainly used for cutting threads at low speeds and therefore does not fulfill the function of the shift wheel in both conventional and high-speed turning. Material: 12,050 (C45), toothed with precision on a precise mandrel with minimal run-out. The ball is of course a pen that is not in the pictures. Everything is also grounded.
