Toolholder Solutions for Moldmaking

Designed for accuracy to meet the demands of machining molds, Lyndex-Nikken offers three advanced toolholder solutions: MMC Collet Chucks, SK Collet Chucks and Shrink Fit Toolholders.

MMC Collet Chucks are highly flexible for machining molds and dies, providing both clearance and accuracy in small diameter cutting. Featuring a slim and compact body for precision machining with small diameter tools (up to 0.5"/12 mm), the MMC Collet Chuck is ideal for high-speed machining applications where clearance is needed. The MMC is precision ground and pre-balanced which helps ensure accuracy and reliability during high-speed operations up to 40,000 rpm. Runout accuracy is reported to be 0.00012" or better at four times diameter stickout of the cutting tool.

SK Collet Chucks feature a narrow body design to access tight spots in a mold. Key to the design is the patented titanium nitrided bearing nut that increases cutting performance and tool life durability by providing more efficiency than a conventional ball bearing built-in nut; good sliding effect due to surface hardness of HV-2,200; no damage — no friction or corrosion occurs internally; less micro vibration with collet flange contact; and an increase in cutting performance and tool life durability with more cutting rigidity.

The company’s Shrink Fit Toolholders provide optimal surface finish and extreme gripping, making them ideal for high-speed moldmaking applications. Shrink Fit Toolholders have 0.0002" or better runout and are pre-balanced for up to 20,000 rpm — this results in increased cutting tool life, material removal rate and mold accuracy. Lyndex-Nikken also offers a heat induction Shrink Fit Unit to quickly heat up the toolholder to expand the inside diameter. As the holder cools, it shrinks down around the tool, keeping the shank securely in place with its concentric gripping strength.
