Challenge SCM Corner Rounding Machines

Challenge Machinery builds production-grade corner rounding machines designed for commercial print environments. The Challenge SCM hydraulic corner rounder delivers consistent, high-force cuts through thick stock and laminated materials that would bog down lighter machines. Challenge also offers manual models for shops that need precision without the hydraulic power. As an authorized Challenge Machinery dealer, Mid-State Litho has direct access to parts, service, and factory support. Challenge builds their equipment in Grand Blanc, Michigan — just 20 minutes from our facility — giving us the closest dealer relationship of any authorized distributor.

Lassco Wizer Corner Cutters

Lassco Wizer corner cutters include the CR-55 manual, CR-50P electric, and CR-50XP pneumatic models. The pneumatic CR-50XP is the fastest and highest-force option in our lineup, designed for production binderies and finishing departments that process high volumes daily. The electric CR-50P handles medium to high daily volumes with motorized operation and consistent results. The manual CR-55 is a solid workhorse for shops doing occasional corner rounding. Lassco Wizer machines are known for durability and straightforward operation. Contact our team for help choosing the right Lassco model for your production requirements.

How to Choose the Right Corner Rounding Machine

Manual corner rounders are best for occasional use and small batches — business cards, gift tags, and short-run specialty items. They require no power and have the lowest upfront cost. Electric corner rounders suit daily production environments with medium to high volume, delivering consistent results without operator fatigue. Pneumatic and hydraulic corner rounders handle the thickest stock and highest volumes — laminated materials, heavy board, and production runs of thousands of pieces per day. Consider your daily volume, maximum stock thickness, and whether you need multiple die radius options when selecting a machine. Contact Mid-State Litho for a personalized recommendation based on your production needs.

Frequently Asked Questions

What is a corner rounding machine and what is it used for?

A corner rounding machine (also called a paper corner rounder or corner cutter) cuts precise rounded corners on stacks of paper, card stock, or board. It is used by print shops, binderies, and finishing departments to add a polished, professional finish to business cards, postcards, menus, ID badges, greeting cards, and promotional materials. Corner rounding also eliminates sharp edges for improved durability and safety.

What is the difference between manual, electric, and pneumatic corner rounders?

Manual corner rounders require hand operation and are best for occasional use and small batches. Electric models use a motor to cut consistently at higher speeds, ideal for daily production. Pneumatic (air-powered) and hydraulic models deliver the highest force and fastest cycle times, designed for thick stock, laminated materials, and high-volume production environments.

What corner radius sizes are available?

Most corner rounding machines use interchangeable dies that allow you to switch between different radius sizes. Common radii include 1/8 inch, 1/4 inch, 3/8 inch, and 1/2 inch. Some machines offer metric die options as well. The radius you need depends on the finished product — business cards typically use 1/8 or 1/4 inch radius.

How thick of a stack can a corner rounder handle?

Stack capacity varies by model and power type. Manual corner rounders typically handle 1-3 sheets at a time. Electric models can process stacks of 10-30+ sheets depending on paper weight. Pneumatic and hydraulic machines handle the thickest stacks — up to 2 inches or more of paper in a single stroke.

Can corner rounding machines cut laminated materials?

Yes, but machine selection matters. Standard manual corner rounders may struggle with laminated stock. Electric models handle light to medium lamination. For consistently clean cuts on laminated materials, a pneumatic or hydraulic corner rounder (like the Challenge SCM hydraulic or Lassco Wizer CR-50XP pneumatic) delivers the force needed to cut through laminate layers without tearing or delaminating.
