Machining of Bulky Parts

What is a Bulky Part? Any part that is too large or difficult to handle using normal work holding or machining methods. For example, to machine an aluminium profile that is 6 feet long would require a CNC mill with a large enough bed to handle the part length. 

  What to do? With standard components, Suhner offers several options to accomplish the task. One option would be to use the Suhner MULTImaster system, which can drive up to eight (8) drilling spindles with a single electric motor via flexible shafts. This is a worldwide unique solution, thousand times proven since decades. 

  How it works? The MULTImaster system is made up of three (3) main components:

• Drilling spindle – available in three sizes of quill feed units and three sizes of basic drilling spindles
• Flexible shaft (cable which transfers rotary motion) – three standard lengths and sizes available
• Base unit (electric motor with flex shaft connections) – available in different motor sizes

Instead of directly driving a spindle with a motor, the base unit uses a 3 kW motor and belt and pulley combination to drive the drilling spindles through flexible shafts. The flexible shaft can then be connected to a variety of Suhner drilling spindles. 

 

This set-up offers several advantages:

• Efficiency: one motor and controls rather than multiple
• Versatile mounting: mount units in any direction
• Remote operation: move motor away from coolant
• Weight: units are lighter without motor directly coupled
• Close mounting: allows for close hole distances

What is the greatest advantage of the modular Suhner products? In one word, it would simply be flexibility. With the available options of varying speed, flexible shaft length, motor size and a wide variety of spindle types, there is no part too ‘Bulky’ for the Suhner spindle system. 

  It is this kind of flexiblity and ingenuity that has made the company a leader in Automation Equipment for 100 years. The company has a full line of drilling, tapping, milling, multiple spindle heads and slide units.
