Bilz Tool Co. Inc. has developed a new generation of ThermoGrip shrink fit machines. The new model series, ISG3400, feature a bench top and a free-standing machine with the latest technology in liquid cooling and shrink fit technology. One model features completely automated heat shrink cycles and cooling cycles for hands-free operation. The bench-top model features the same capabilities with manual operation.
Both models feature the standard range of shrink fit tool capacity, from 3mm-32mm for carbide and 6-32mm for HSS tooling. The floor standing machine can be expanded up to 50mm with quick-change ThermoGrip coils. The new machines feature fast shrink fit process of 45 seconds or less depending on tool style and size. Both machines are available in 480volt, 3 phase electrical power eliminating the need for an external transformer/generator.
Features of both machines include:
Direct shower cooling process — no risk of operator injury, as tools cool down to room temperature while still in the heating position.
Maintaining tool TIR and concentricity by uniform cooling of the assembled tool within seconds – processor controlled.
No "sweating" of the toolholders due to condensation of (too) cold cooling adapters from "active" coolers.
Protection against corrosion for the tool and the shrink fit chuck with supplied coolant.
Minimal electrical consumption. 98 percent of the energy is transformed into "heating power" via the patented induction coil.
Contour independent cooling — No damage of the cutting edge by cooling elements and no additional cooling adapters necessary for different shrink chuck geometries
Patented quick change coil system — Developed by Bilz for simplified coil change Control Panel and software simply select the tool style and size and start the heating process — fixed parameters for all standardized ThermoGrip shrink chuck geometries are included.
The automated feature prevents overheating of shrink chucks and insures proper handling.
Up to 50 custom tool settings for special parameter tools can be stored.
Features of the new ISG3400WK:
All features above, plus Fully automatic shrinking and cooling process — no risk of operator burn injuries.
Both toolholder lift and coil tower are fully automated.
No handling of "hot" shrink holders, single location process of heating and cooling without handling of the tool assembly.
Related Glossary Terms
- chuck
chuck
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- 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.
- high-speed steels ( HSS)
high-speed steels ( HSS)
Available in two major types: tungsten high-speed steels (designated by letter T having tungsten as the principal alloying element) and molybdenum high-speed steels (designated by letter M having molybdenum as the principal alloying element). The type T high-speed steels containing cobalt have higher wear resistance and greater red (hot) hardness, withstanding cutting temperature up to 1,100º F (590º C). The type T steels are used to fabricate metalcutting tools (milling cutters, drills, reamers and taps), woodworking tools, various types of punches and dies, ball and roller bearings. The type M steels are used for cutting tools and various types of dies.
- toolholder
toolholder
Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.
- total indicator runout ( TIR)
total indicator runout ( TIR)
Combined variations of all dimensions of a workpiece, measured with an indicator, determined by rotating the part 360°.
