Band saw tooth tip hardening machine Type BHM 80

Heating occurs in a continuous process. A cooling water system is required for cooling the generator or inductor that heats or hardens the teeth.

Direct connection to the water main at a pressure of 3 bar. Only to be recommended if the water is not too cold and the price of water is low.
Cooling unit that cools down the heated water during operation and returns it to the generator with the help of a pressure pump (operating pressure 3.5 - 4 bar expensive solution).
Cost-effective solution
1 water tank with a content of ca. 450 litres with a pressure pump 3.5 - 4 bar fitted with an adjustable temperature probe that controls a solenoid valve feeding fresh water from the mains. For an 8-hour day and normal daytime temperature the amount of water used is approx. 60 litres. The heated water then runs off via an overflow into a drain or can be collected for other purposes.
Note: The water is used for cooling only and is not contaminated.

Technical data:

Dimensions:	Width: 230 cm
	Depth: 75 cm
	Height: 130 cm
Total power:	approx. 3 kW
Water flow:	(Inductor) approx. 2.5 litres/min.
Drive power:	Band saw feed (friction drive) steplessly adjustable via gear motor
	by means of a potentiometer
Winder unit:	via slipping clutch with gear motor drive
Generator power:	2 kW for the Himmel generator HG 34 shown
Weight:	205 kg
Operating voltage:	230/400 Volt, 3 Phase, 50 cycles or
	230/440 Volt, 3 Phase, 60 cycles
	Other voltages via a transformer
Note:	All types and makes of generator from 2-6 kW with cable outlet
	can be used, heating capacity 40-50 teeth/min.
	Tube generators are better suited for this purpose. Electronic converters or generators are only partly suitable for the purpose of the operating time.
