Punch Press
Thursday, June 21st, 2012Punch presses are used when processes require hole to be punched in material. From small and manual to large, complex CNC machines, punch presses vary depending on the scale of the operation. Most punch presses have either a portal (bridge) frame or a “C” type frame. The following are some of the criteria used to determine what type of punch press you need:
Size of work area
Drive type
Force rating
Weight of the workpiece
Drive Type
The drive type is the system used to deliver force to the ram. There are several different types used for different purposes.
Flywheel
A flywheel is a constantly rotating machine. With flywheel, adjusting the speed during the process is difficult. With the advent of newer systems, these types of presses are no longer common.
Mechanical
There are two types of mechanical punches: full revolution and part revolution. The full revolution requires the crankshaft to rotate a full turn before coming to a stop. The full turn is necessary because specific slots must catch raised keys in order to stop the rotation. More advanced machines use a part revolution which works with a braking system.
Hydraulic
These presses use a hydraulic cylinder are can be controlled by a valve or by a valve and feedback system. Valve controlled hydraulic presses let the ram stroke up and down in a one-stroke operation. The valve and feedback system offers control proportionally so the stroke can be set to fixed points. This system provides more flexibility and increases punching rates.
Servo drive turret
This type of punch press uses twin AC servo drives connected to the drive shaft. This system is effective because it has the speed of hydraulic systems as well as the control provided with clutches and brakes. Although this type of punch matches the speed of hydraulic systems, it has no hydraulic parts which means it needs less maintenance. Servo drives also reuse the energy that gets generated during deceleration. This lessens the amount of power needed to run the machine.

The Brake Press
Wednesday, June 20th, 2012The brake press, also known as press brakes are very useful shaping sheet metal. Typically they work with a table below which holds the die and a moveable beam above where the punch is located. There are several types of brake presses available and they are described by the types of force applied in the process.
Mechanical Press – A clutch is used along with a flywheel to operate a crank. Mechanical presses are known for their speed and accuracy.
Hydraulic Press – Uses two hydraulic cylinders located on the sides of the press. They move the upper beam.
Servo-electric Press – Exerts force by driving a belt drive or ballscrew with a servo-motor (a motor with encoders to provide accurate positioning and speed).
Pneumatic Press – Uses air pressure to provide force.
Applications
Mechanical presses have long been the dominant type in the world of machining. But since the 1950s, hydraulic presses have become the most popular as a result of advances in hydraulic and computer technologies. Now, hydraulic presses are known to be very reliable and accurate. They are also considered a safe option because the ram’s motion can be stopped much easier than that of flywheel-driven mechanical presses. Servo-electric and pneumatic presses are ideal for processes requiring lower amounts of force (tonnage).

Novel Use For a Water Jet
Thursday, June 14th, 2012Water jets are great for processing metals for food-related uses. But what about food itself? Paprima’s Ultra-High Pressure water jet is a great method for cutting food for several reasons. Water jets are much more hygenic than traditional methods because they don’t involve blades which have been known to transfer bacteria and pathogens onto food products. And this particular water jet uses a continuous stream of drinking water rather than mixing water with an abrasive. The UHP water jet has an opening of about .004″ which is small enough to cut delicate foods producing a clean cut with no bruising.
The nozzle on the UHP moves water at 3 times the speed of sound providing extreme cutting power. The diamond nozzle should be able to last approximately 3 months being used continuously.
Milling 101
Tuesday, June 12th, 2012Milling is basically the process of removing material. It began centuries ago as a way to process grains using stones.
Eventually, it also came to include metal processing with rotating cutting tools. As milling evolved, the array of tools that could be employed increased greatly as did the precision. Choosing the right tool and the proper machining parameters in milling is essential to achieve an optimum outcome.
Types of Milling
Face Milling – Used for making flat surfaces. The cutters usually have a single row of inserts. The tools used for face milling will preferably have a lead angle for long tool life.
Slot Milling – Used to produce slot and channels. Mainly, slot milling is done with either a disk mill or an end mill. Disk mills are usually used for operations that are perpendicular to the spindle rotation. Types of disk mills are high-speed steel, brazed carbide, and indexable-insert-based. These will be used for operations perpendicular to the spindle rotation. End mills are used when the slot needed must be parallel to the spindle rotation and often result in poorer quality due to poor chip formation and other factors. End mills have a smaller tool diameter and greater length which causes them to be less stable than all other milling cutters.
Periphery Milling – Creates a primary surface that is parallel to the spindle rotation. Often times, there is also a secondary surface generated. Types of periphery milling cutters include: solid carbide, high-speed steel, and indexable-insert-based.
Specialty Applications
There are additional types of milling that can be used for specific jobs. Here are a couple:
Ramping – Used for making angled surfaces or for making a pocket at the point of entry.
Helical and Circular Interpolation – Used to create a cylindrical surface or to make entry points that can be used later.
Strippit LP-1225: Punching Productivity – Laser flexibility
Monday, June 11th, 2012The Strippit LP-1225 machine redefines laser/punch combination technology with an efficient, economical design from the company that introduced combination technology to the marketplace in 1978. Why Combination Technology? In today’s manufacturing environment the need to produce piece parts more efficiently is a constant demand. Laser cutting reduces secondary finishing, cuts
exotic materials and processes intricate shapes. Combination technology is ideal for components that require holes, forms and profiles. While combination technology provides all-in-one processing, it often requires a substantial investment, forcing users to produce complex, higher value parts in order to achieve a return on investment. The Strippit LP-1225 redefines combination
technology with the perfect balance of functionality and economy, combining field proven LVD – GE Fanuc laser technology and LVD Strippit punch press technology in a price sensitive integrated machine.
The Laser
GE Fanuc CO2 laser resonator generates up to 2500 Watts of cutting power to cut intricate shapes in metals and non-metals Complete integration of the GE Fanuc laser source, CNC control, AC digital motors and amplifiers offers a high degree of reliability and superior processing speed.
GE Fanuc resonator is equipped with long-life discharge tubes, a cyclone cleaner unit, and photo catalytic elements to maximize resonator performance and longevity Laser power is matched to the axis speed to achieve a constant width of cut with a small heat-affected zone.
Large 11.8” x 17.7” (300 mm x 450 mm) programmable parts chute allows finished laser-cut parts to be directed through a drop door, eliminating the need to tab or micro-joint laser-cut parts for manual removal from a nested sheet.
The Punch Press
Stress relieved, single piece bridge frame and widespread axis bearing system provide rugged performance Precision servo controlled hydraulic system delivers high punching and forming rates Direct drive axis reliably maintaining accuracy of ± .004” (0,10 mm) with a repeatability of ± .002” (0,05 mm) over the entire table is consistently achieved.
Compactly designed 33-station thick tool style turret lends large capacity Three 2” (50,8 mm) direct-drive auto index stations accept standard, tapping or wheel style tooling Quick change dies bases in the 1/2” (12,7 mm) and 1-1/4” (31,7 mm) stations reduce tool change time and increase uptime Smart Clamp™ feature automatically determines exact clamp locations to provide the smallest possible nopunch zone.
