Jergens Inc. announces fixture plate machining kits and new receiver bushing plugs for its popular line of Ball Lock quick-change mounting systems. The machining kits consist of one fixture plate, four extra-long Ball Lock shanks and four spacers that provide clearance between the fixture plate and subplate below. This open space allows cutting tools to "break through" the fixture plate without damaging the subplate, making it possible to machine fixture plates while mounted to the same subplates they will be used with during production.
Another convenient development is the company’s new simple-to-install plugs that prevent chips and coolant from accumulating inside receiver bushings that are not in use (during certain operations). This saves time by eliminating the need to clean out receiver bushings in between setups. The receiver plugs are blue anodized aluminum, a durable construction for better resistance to hot chips when compared to plastic plugs. The flush mount design does not protrude above subplate surface making it easy to clean of and ensuring no interference in machining. These plugs are available in standard sizes to accommodate different hole openings, and come with an O-ring and tapped hole for easy installation.

- bushing
bushing
Cylindrical sleeve, typically made from high-grade tool steel, inserted into a jig fixture to guide cutting tools. There are three main types: renewable, used in liners that in turn are installed in the jig; press-fit, installed directly in the jig for short production runs; and liner (or master), installed permanently in a jig to receive renewable bushing.
- clearance
clearance
Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- fixture
fixture
Device, often made in-house, that holds a specific workpiece. See jig; modular fixturing.
