Dynamic Balancing Machines
The DB1 and DB2 range are single plane, static balancing machines. The DB3 and DB4 are two plane, dynamic balancing machines. The Single plane machines are often used for balancing relatively flat objects such as grinding wheels, cutter blocks, impeller, diamond polishing plates etc. The Dynamic machines can be used to balance any rotating component, the DB3 having a maximum component weight of 20 Kgs, and the DB4 of approximately 45 Kgs.
All machines are extremely simple to operate. After calibration the imbalance position, is indicated within approximately 5 seconds of starting the machine.
The exact weight needed for balance can be displayed to a resolution of 1 milligram. The output can also be in ounces. Software provided allows the machines to be connected to a PC for graphical and numerical indication and to allow balancing parameters and results to be printed for certification purposes. Result can be shown in terms of G, g/mm or pass/fail.
Purpose made mandrels are recommended. Coborn are able to produce mandrels to your exact specification or requirements, including Hydraulic Mandrels for small components.
The DB2 range includes thre machines that allow versatility, the basic DB2 has static pillars, the DB2+ has movable pillars allowing various mandrels to be used, and the DB2B has two pick up sensors which are independant, so the component can be balanced on the left or right of the moveable pillars. The DB2B can be changed into a DB3 on-site without mechanical modification, by exchanging the Amplifier, if move complicated components requiring dynamic balancing are undertaken. Please see the Product Information Page for more details about the entire range.

PB2
The very successful PB1 has been superseded by the updated PB2. The physical characteristics are exactly the same. The internal design has been simplified and obsolete or non conformity components removed.
This should mean repair prices can be kept to a minimum and the list price and spare part prices can be kept at the same level as the old PB1.
The latest COBORN balancing machine has been designed in-house to fill a niche in the marketplace. It is a portable, hand-held device, battery-powered, and capable of in-situ balancing. Principle uses are for gem polishing skive plates and machine tool spindles.
Easy Operation
Push button operation and auto set up means balancing becomes quick and simple.
Dual Display
Liquid crystal display for data display, and linear scale to show out of balance.
Strobe
Built-in strobe light for identification of out of balance position. The light is mounted in the rear of the enclosure to enable the displays to be read at the same time.
Pickup
External custom-designed pickup allows sensitive balances to be obtained.
Battery Powered
The unit is powered from a high powered alkaline battery pack. This enables the user to operate the equipment in any environment. A power supply / battery charger is also supplied as standard.
