PRESI MINITECH 300 SP1 – Maximum Flexibility and Power for Large Sample Surfaces

The MINITECH 300 SP1 by PRESI is the most powerful manual single-wheel grinding and polishing machine in the MINITECH series. Designed for laboratories that process larger samples or require a higher removal rate, it combines a generous working area with maximum precision and robustness.

By accommodating work wheels up to 300 mm in diameter, the MINITECH 300 SP1 offers a significantly larger surface area. Its high-resistance composite housing and intuitive controls make it the perfect choice for metallographic sample preparation in both industry and research.

Key Features & Benefits:

• Large Working Area: Compatible with wheels from Ø 200 mm to Ø 300 mm – ideal for large components or the simultaneous manual processing of multiple samples.
• Superior Smoothness & Power: A reinforced drive ensures constant speed and vibration-free polishing, even under high pressure and with large wheels.
• Intuitive LCD Control: Clear display and easy adjustment of speed, direction of rotation (clockwise/counter-clockwise), and time.
• Durable Design: The corrosion-free composite housing is chemically resistant and can be cleaned effortlessly thanks to its smooth surfaces.
• Optimized Water Management: An integrated rinsing system with flexible water supply guarantees efficient cooling and prevents residue on the wheel.
• Ergonomics: Despite the larger wheel capacity, the machine remains compact and offers an optimal working height for precise manual sample guidance.

Technical Specifications at a Glance:

• Number of Wheels: 1 (Single-wheel machine).
• Wheel Diameter: Ø 200 mm to Ø 300 mm.
• Speed: Variably adjustable from 50 to 600 RPM.
• Rotation Direction: Selectable clockwise and counter-clockwise rotation.
• Drive: Powerful motor with soft start for maximum control.
• Housing: High-strength, chemically resistant composite material.

Areas of Application:

The MINITECH 300 SP1 is the ideal tool for preparing large-surface samples in the automotive industry, aerospace, and heavy industry. It is excellently suited for metals, alloys, and composite materials requiring large-scale flatness.
