Simple installation, use and programming as well as flexibility and efficiency are the factors that are increasingly driving the use of robots in the engineering sector. A growing trend, in Italy and abroad, that not only considerably simplifies the factory and increases its productivity, but also entails a considerable progress on the work front by delegating risky and repetitive tasks, with low added value, to industrial and collaborative robots. But not all robots are the same or capable of the same ‘miracles’. This is evident when analysing the collaboration that has grown between a leading multinational company in automation and industrial robotics and a globally-recognised excellence in the development, production and sale of highly technological components for machine tools. A collaboration that has made a difference, because it has led to the development of a state of the art robot-spindle application.

Spindle Showdown! Product Comparison: 60C to HSD AT/MT 1073

Spindle Showdown!

Product Comparison: 60C to HSD AT/MT 1073

Spindle Showdown Product Comparison 60C HSD MT1073

This Spindle Showdown will compare our High Speed 60C Spindle to the HSD AT/MT 1073.

The HSD AT/MT 1073 is a very common type of spindle in a lot of machine shops. It’s an entry level style of spindle for table machines. This model runs at 24k RPM, has 3kw of power and a 2 pole motor. It is fan cooled with a shaft driven fan so it can get very loud. It has an aluminum body, harting connector, and weights over 17 pounds. If you wanted to cut at higher speeds, you’re limited to only 24k RPM.

If you’re looking for an upgrade/replacement, we recommend our 60C. It’s half the weight of the HSD 1073 and is almost equal in power. It’s a 4 pole motor so it has about double the torque of the HSD. It cuts twice as fast, smoother, and with high precision. As you cut, the dimensions will stay stable because of the liquid cooling. It will also last longer.

We can customize your upgrade to ensure exact compatibility. The voltage, harting connector, and collet dimensions will be fit to your needs.

Product Highlight – HSK 63F Gripper

Product Highlight – HSK 63F Gripper

HSK 63F Tool Clamp Gripper

This product highlight is on our HSK 63F Gripper. (Video Below)

The tool holding clamp group is a.k.a. a gripper. The gripper is a wearable item just like bearings. Replacing your tool gripper once or twice is common.

Our HSK 63F Gripper is compatible with all HSK 63F, HSK 63B, and HSK 63D spindles. The tool gripper is interchangeable with the REBO and OTT Jakob HSK models.

Note: Grippers made by Ott Jakob and IMS require a tool to be present if the spindle is rotating. Do not mix fingers of the gripper even if it is the same manufacturer.

Our HSK 63F Gripper is of hard alloy steel, precision ground surfaces, and a low friction wear resistant coating. The grippers are of a common dense standard. These high speed designs are for high speed machines. These grippers have been individually balanced to provide low vibration usage during the life of the clamp group.

Maintenance is very important for your high speed gripper to prevent any excess or expedited wear or damages. Maintain with a rust preventative spray on your gripper and the correct concentration of coolant for corrosions. Check tool grippers weekly for wear and lubricate the tool  grippers every month with grease. Replace the tool if it is worn or damaged. You can cause damage to the rest of your equipment if you do not replace the tool. 

We will have a more detailed and comprehensive video blog about maintenance and care of your spindles and equipment in the upcoming weeks. Be sure to check back as we will be launching a continuous series on our spindles, spindle maintenance, and more!

Shop now for this HSK 63F Gripper.

Latest Repair – GMN Spindle (TSSV – 20k rpm, 4 pole, liquid cool)

Latest Repair

GMN Spindle

New repairs are rolling on this new year and we want to provide you a behind the scene look at one of our repairs.

GMN TSSV – 20k rpm, 4 pole, liquid cool

GMN Spindle (TSSV - 20k rpm, 4 pole, liquid cool)

Stay tuned and we’ll update you as we:

  • Inspect the spindle
  • Set up a cooling system for spindle
  • Vibration analysis to see if bearings showing signs of wear and/or damage
  • Design a high pressure hydraulic system to open the chuck to provide a tool change
  • Evaluate it and present a report to the customer

If it requires disassembly, we request permission from the customer.

Spindle Comparison: 70C versus IMT ECO80 Spindle

Spindle Comparison: 70C vs IMT ECO80 Model

This post is a spindle comparison of two HSK 25E spindles. Both are high precision and high speed: 30,000 and higher. The 70C is manufactured in the USA and the IMT comes from Germany.


70C is designed to fit in the same envelope as an IMT ECo80 spindle and in this post, I will highlight some of the features of the 70C.

The 70C has a similarly sized shaft to allow the same access as the IMT model. The 70C has a 316 stainless steel cover to further protect the spindle from splashing.Spindle Comparison: 70C vs IMT ECO80 ModelSpindle Comparison: 70C vs IMT ECO80 Model


70C also has a splash guard in the rear.

Spindle Comparison: 70C vs IMT ECO80 Model



70C is a 2.7kW motor compared to the IMT’s 1.9kW (To be fair: IMT does offer a 2.8kW version. HS Spindles does as well but it is a 4 pole motor with much higher torque).

The 70C uses larger bearings in the front and is a more robust design throughout.

The 70C uses a stronger drawbar than the IMT and allows for commercially available clamp groups to be used (Bellodi, OTT Jakob, IMS).

70C is capable of 40,000 rpm versus this IMT model rated at 30,000 rpm.

The 70c is made in the United States and the IMT is made in Germany.


Dynamic Balancing – Vibration Analysis

All spindles are dynamically balanced and have a vibration analysis performed. If any critical speeds are detected, we’ll inform you of the speed zones to avoid to help your spindle last longer.

We also offer rotordynamic analysis services to machine builders, spindle manufacturers and test rig developers. Shafts and shaft mounted items are analyzed in reference to the type of bearings, stiffness and natural frequency. Shaft mounted items can be designed with confidence knowing the critical speeds of the assembly and how design them in regards to mass, center of gravity and polar inertia properties.
